vantin max dose

The disposition of cefpodoxime in 24 subjects with various degrees of renal function after administration of a single oral dose of 200 mg of cefpodoxime proxetil (equivalent to 200 mg of cefpodoxime activity) was studied. Subjects were assigned to one of four groups (six per group): group I, normal renal function (creatinine clearance [CLCR], greater than ml/min); group II, mild renal impairment (CLCR, 50 to 80 ml/min); group III, moderate renal impairment (CLCR, 30 to 49 ml/min); or group IV, severe renal impairment (CLCR, 5 to 29 ml/min). Although cefpodoxime terminal elimination half-life in group I (2.55 +/- 0.25 h [mean +/- standard deviation]) was not significantly different from that in group II (3.53 +/- 0.74 h), the half-life values for group III (5.90 +/- 1.67 h) and group IV (9.80 +/- 1.21 h) were significantly prolonged compared with those of group I. The mean absorption rate constant was similar among groups and ranged from 0.68 to 0.85 h-1. All groups exhibited absorption lag-times which were comparable (0.30 to 0.41 h), and the apparent volume of distribution was similar among groups. Cefpodoxime apparent total body clearance (CLP/F) values in groups II, III, and IV (132 +/- 29, 112 +/- 41, and 55.7 +/- 9.9 ml/min, respectively) were significantly lower than that in group I (238 +/- 44 ml/min). Cefpodoxime CLP/F was positively correlated with CLCR (r2 = 0.79; P less than 0.05): CLP/F = (1.9 CLCR) + 18.4. Renal clearance also declined with decreasing renal function. Adjustments in cefpodoxime organism and on the site and severity of infection. Simulated plasma concentration-time data from this study suggest that 200 mg of cefpodoxime proxetil administered every 12 to 24 h to subjects with CLcr between 30 and 49 ml/min and 200-mg dose taken every 24 h by subjects with CLcr between 5 and 29 ml/min will maintain cefpodoxime concentration in plasma similar to those in subjects with normal renal function who receive a standard dosage mg every 12 h.

vantin reviews

Cefpodoxime proxetil is a new orally administered cephalosporin which has a favorable spectrum of activity against respiratory pathogens. Concentrations of cefpodoxime in serum and bronchial mucosal biopsy were measured in 13 patients without active respiratory tract infection undergoing fibreoptic bronchoscopy. Samples were taken between 1 and 6 h after a single oral dose of cefpodoxime proxetil equivalent to 200 mg of cefpodoxime base. In twelve patients who completed the study, mean serum concentrations were 1.7 mg/L (S.E.M. 0.4) and in ten patients mean bronchial biopsy concentrations were 0.9 mg/L (S.E.M. 0.2). The mean penetration was 54% (S.E.M. 6.1). Cefpodoxime was undetectable in biopsies from two patients. The majority of serum and biopsy concentrations were in excess of the MIC90S for Haemophilus influenzae and Streptococcus pneumoniae. Cefpodoxime proxetil may be worthy of further study in clinical trials in patients with respiratory infections.

The disposition of cefpodoxime after single, oral 200-mg doses of cefpodoxime proxetil (cefpodoxime equivalents) was investigated in an open-label study of six patients with end-stage renal disease currently maintained on hemodialysis. Subjects were randomly assigned to one of two treatment groups, which differed in the sequence of the interdialytic and intradialytic periods. Doses were separated by at least 2 weeks. Blood samples were serially collected for 48 hours after each treatment; if obtainable, urine was also collected over this same period. During the intradialytic period, hemodialysis was scheduled to begin approximately 3 hours after dosing, and dialysate was collected before and until the end of dialysis. Average cefpodoxime elimination half-life for the interdialytic period was 18.0 +/- 6.5 hours; apparent total body clearance was 28.6 +/- 13 mL/minute. The half-life during hemodialysis, 2.66 +/- 0.74 hours, was considerably shorter than that after hemodialysis, 19.2 +/- 3.5 hours, in the intradialytic period of the study. Hemodialysis clearance of cefpodoxime was 120 +/- 31 mL/minute, which was 57.1 +/- 13% and 71.7 +/- 25% of the hemodialysis clearance for urea nitrogen and creatinine, respectively. The 2.86 +/- 0.25 hour hemodialysis session removed 22.4 +/- 2.9% of the administered dose, as assessed by cefpodoxime recovery in dialysate. A maximum rebound in cefpodoxime plasma concentration of 0.41 +/- 0.33 mcg/mL was observed, at about one-half hour after the end of hemodialysis. Based on these results, dosage adjustment is not required, but extension of the dosing interval is warranted.(ABSTRACT TRUNCATED AT 250 WORDS)

U-76,252 is the prodrug of U-76,253. MICs of U-76,253 were 0.015 to 0.06 microgram/ml for greater than or equal to 90% of the strains of Streptococcus spp., Haemophilus influenzae, and Proteus mirabilis; 0.25 to 1 microgram/ml for Branhamella catarrhalis, Escherichia coli, Klebsiella spp., and Citrobacter diversus; 1 to 8 micrograms/ml for Staphylococcus spp.; and 2 to greater than 16 micrograms/ml for other members of the family Enterobacteriaceae and Aeromonas hydrophila; for 72% of the latter group, MICs were less than or equal to 4 micrograms/ml. MICs for Pseudomonas aeruginosa and Enterococcus faecalis were greater than 16 micrograms/ml.

vantin renal dosing

The bioavailability of cefpodoxime proxetil tablets relative to an oral solution of cefpodoxime proxetil in a sucrose/alcohol/citric acid vehicle was studied in 11 healthy volunteers in a randomized, crossover study. Fasted subjects took one cefpodoxime proxetil 100 mg tablet or 50 mL of a 2 mg mL-1 cefpodoxime proxetil oral solution on two separate occasions. In a third study period, all subjects took a 100 mg dose of the oral solution with a high-fat meal to investigate the effect of food on cefpodoxime proxetil absorption from the oral solution. Serial blood samples were obtained over a 24 h period, and urine was collected for 48 h after dosing. Cefpodoxime concentrations in plasma and in urine were determined using HPLC methods. The bioavailability of cefpodoxime proxetil tablets relative to the oral solution was 82%, as determined from AUC ratios. There was no difference in the rate of cefpodoxime absorption between dosage forms. Food had no effect on the extent of drug absorption from the oral solution but did result in delayed absorption. These results suggest that complete dissolution of cefpodoxime proxetil is critical for optimal bioavailability.

Twenty nine children were treated with cefpodoxime proxetil (CPDX-PR, CS-807) and the clinical efficacy and side effects were evaluated. Ages of the patients ranged from 2 months to 10 years. Dose levels of CPDX-PR ranged from 7.5 to 12.0 mg/kg/day for 5 to 12.7 days. The 29 patients included 9 tonsillitis, 2 otitis media, 5 scarlet fever, 3 bronchopneumonia, 1 lymphadenitis, 8 urinary tract infections and 1 staphylococcal scalded skin syndrome, and they were evaluated for the clinical efficacy of CPDX-PR. Results were excellent in 21 and good in 8 patients. Out of the 29 patients, 3 cases showed diarrhea and 2 cases showed elevated GOT and GPT. The pharmacokinetics of CPDX-PR was studied in 9 patients whose ages ranged from 1 to 9 years. The serum peak concentrations of CPDX in 5 patients were between 1.37 and 4.10 micrograms/ml (mean: 2.53 micrograms/ml) at 1 to 6 hours after dosing 3 mg/kg before meals. Those of 4 patients ranged 3.29 to 4.88 micrograms/ml (mean: 4.36 micrograms/ml) at 2 hours after administering 6 mg/kg before meals. Portions of CPDX excreted into urine within 6 hours ranged from 20.3 to 34.3% (mean 27.1%) in 5 patients who were given 3 mg/kg, and ranged from 24.1 to 65.7% (mean 41.1%) in 4 patients given 6 mg/kg.

For kinetic studies,24 Wister rats of either sex, 3 months of age, (180-210 gm) were used.(Group I-IV; n=6) Blood samples collected from each animal of Group IV through heart puncture at 0 hour to serve as predrug control. All the group (I-IV) received cefpodoxime proxetil 20 mg/kg once orally as a single dose. At the end of 1,4,12 and 24 hour post oral administration, GroupI,II,III and IVwere utilized for kinetic studies. Blood samples were collected from each animal and vital organs viz brain, lung, liver, spleen, kidney and heart were dissected out for drug analysis and determination of weight. For biochemical parameters, tissue residue and spermatozoa motility, twelve male rats were randomly divided into Groups A and B (n=6) Group B received cefpodoxime (20mg/kg orally bid 7 days) while Group A served as control. Biochemical parameters [Blood glucose, protein, Aspartate transaminase(AST), Alanine transaminase(ALT)and hemoglobin] were measured at 0 and 7 th day while sperm count (total,live and dead)and mean organ weight (study and control group) and tissue residue of drug were evaluated at the end of treatment. Absorption of cefpodoxime was observed at 2 hour and reached a maximum at 4 hour and persisted in blood till 24 hour. Elimination half life in lung was highest followed by heart, liver, kidney and spleen while t½ k in plasma was very low suggesting more affinity of cefpodoxime for tissues than blood.

Linezolid is the first of a new class of antibacterial drugs, the oxazolidinones. It has inhibitory activity against a broad range of gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), glycopeptide-intermediate S. aureus (GISA), vancomycin-resistant enterococci (VRE) and penicillin-resistant Streptococcus pneumoniae. The drug also shows activity against certain anaerobes, including Clostridium perfringens, C. difficile, Peptostreptococcus spp. and Bacteroidesfragilis. In controlled phase III studies, linezolid was as effective as vancomycin in the treatment of patients with infections caused by methicillin-resistant staphylococci and also demonstrated efficacy against infections caused by VRE. Further phase III studies have demonstrated that linezolid is an effective treatment for patients with nosocomial pneumonia, for hospitalised patients with community-acquired pneumonia, and for patients with complicated skin or soft tissue infections (SSTIs). In these studies, linezolid was as effective as established treatments, including third-generation cephalosporins in patients with pneumonia, and oxacillin in patients with complicated SSTIs. Oral linezolid 400 or 600mg twice daily was as effective as clarithromycin 250mg twice daily or cefpodoxime proxetil 200mg twice daily in the treatment of patients with uncomplicated SSTIs or community-acquired pneumonia. Linezolid is a generally well tolerated drug. The most frequently reported adverse events in linezolid recipients were diarrhoea, headache, nausea and vomiting. Thrombocytopenia was also documented in a small proportion (about 2%) of patients treated with the drug.

The antibacterial activity of cefpodoxime proxetil was studied in an in-vitro model simulating doses of 100, 200 and 400 mg. Strains of Klebsiella spp. Proteus mirabilis, Escherichia coli, Streptococcus pyogenes, and Haemophilus influenzae were effectively reduced by a dose of 200 mg. While for Esch. coli no dose-activity relationship was observed--the maximal effect was achieved with a simulated dose of 100 mg--Staphylococcus aureus could be reduced effectively only by a simulated dose of 400 mg. The lower doses showed stepwise lower activities. Apart from broad spectrum beta-lactamases like SHV 2 or TEM 5 the presence of plasmid coded beta-lactamases in Esch. coli and H. influenzae did not affect the antibacterial activity of cefpodoxime proxetil. The results show that cefpodoxime was more active against Gram-negative bacteria than amoxycillin, and comparable activity to intramuscular cefotiam in the in-vitro model.

The aim of this study is to develop a simple and applicable HPLC method for the detection of cefpodoxime acid (CFA) in rabbit plasma after oral administration of cefpodoxime proxetil (CFP) loaded chitosan-alginate (CH-ALG) beads formulation. CFP is a prodrug that is deesterified in vivo to its active metabolite CFA to exhibit antibiotic activity. Chromatographic separation of CFA and internal standard (IS) was achieved by a RP18(C18), Phenomenax®100, (250×4.6mm) with the mobile phase consisting of (0.02mol/l (20mM) ammonium acetate solution and acetonitrile (92:8, v/v, pH=4.6) at a flow rate of 1.0ml/min. The method was validated according to the requirements of US-FDA guidelines for bioanalytical method validation. The linear regression analysis for the calibration plots showed good linear relationship (R(2)=0.9905) in the working concentration range of 0.5-50μg/ml. The limits of detection and quantification (S/N=3) were 0.069 and 0.136μg/ml. Plasma CFA levels were successfully determined in rabbit with satisfactory precision and accuracy. The analyte was found to be stable after a number of stability studies. The proposed HPLC method was successfully applied to pharmacokinetic study in rabbits for CFP loaded CH-ALG beads and marketed immediate release (IR) tablets. All pharmacokinetic parameters were assessed.

vantin generic name

Cefpodoxime proxetil is an orally absorbed broad spectrum third generation cephalosporin antibacterial. It is a prodrug that is de-esterified in vivo to its active metabolite, cefpodoxime. After single- and multiple-dose (12-hourly) administration of cefpodoxime proxetil in the therapeutic dose range of 100 to 400mg of cefpodoxime equivalents, average peak plasma concentrations of cefpodoxime range from 1.0 to 4.5 mg/L and occur between 1.9 and 3.1 hours after administration. The half-life of cefpodoxime ranges from 1.9 to 2.8 hours. The absolute bio-availability of cefpodoxime proxetil tablets is 50%, and absorption is enhanced by concomitant administration of food. Raising gastric pH by pretreatment with antacids or H2-receptor antagonists results in reduced absorption. Binding of cefpodoxime to human plasma or serum protein is low (18 to 23%), suggesting that cefpodoxime should readily transfer across the capillary lining into tissues. Cefpodoxime undergoes minimal metabolism in humans. Drug not absorbed is degraded in the gastrointestinal tract and excreted in the faeces. As expected for a drug eliminated primarily by renal excretion, the disposition of cefpodoxime is altered in patients with impaired renal function; the half-life increases, while apparent plasma clearance and renal clearance decrease. The pharmacokinetics of cefpodoxime after oral administration of cefpodoxime proxetil are not affected by age.

This observational study was designed to assess the acceptability of oral antibiotics (including generics) commonly prescribed to children by primary care physicians in France. It was given to 50 pediatricians and 50 GPs in private practice. For each patient, the physician and parents completed a questionnaire, and parents filled out a log for each drug intake.

vantin antibiotic dosage

Cefpodoxime, the active de-esterified molecule of the orally absorbable cephalosporin cefpodoxime proxetil, inhibits streptococci, Neisseria spp., and most Enterobacteriaceae, with MIC50 and/or MIC90 values of less than or equal to 2 mg/L; with regard to the latter family of bacteria, the MIC50 and/or MIC90 values of cefpodoxime are consistently greater than or equal to 4 mg/L for only Enterobacter cloacae, Citrobacter freundii, Serratia marcescens, and Morganella morganii. The MIC50 of cedpodoxime for coagulase-negative staphylococci is greater than 2 mg/L, while the MIC for Staphylococcus aureus strains is 4 mg/L. In comparison with other orally absorbable cephalosporins, cefpodoxime is slightly less active than cefixime, cefetamet, and cefotiam against Gram-negative bacteria, but more active than cefuroxime, cefaclor, and cefalexin. Against staphylococci, the activity of cefpodoxime is comparable to that of cefotiam and cefuroxime, and superior to that of cefaclor, while cefixime and cefetamet have insufficient activity against these species. In common with other cephalosporins, cefpodoxime has no activity against enterococci. In vitro models simulating human serum cefpodoxime concentrations demonstrate that a dosage regimen of 200mg is probably sufficient to treat most infections. However, further study is needed to clarify whether infections due to bacteria such as S. aureus, with higher cefpodoxime MICs, can be treated with this dose regimen.

Cefpodoxime proxetil (CS-807, CPDX-PR), a new cephalosporin antibiotic, was investigated for its usefulness in pediatrics. 1. The total number of patients treated were 21 with their ages ranging from 3 months to 9 years and 1 month, consisting of 5 male and 16 female infants. 2. Single dosages of the drug ranged between 4.4 mg and 5.8 mg/kg with oral administration for 3 times daily in fasting. A total aggregated dosage was between 46.4 mg/kg and 200.0 mg/kg. The length of administration was 3 to 12 days. 3. The breakdown of symptoms were 9 cases of acute pharyngitis, 5 cases of acute tonsillitis, 3 cases of acute bronchitis, and 1 case each of impetigo + purulent rhinitis, cervical lymphadenitis, scarlet fever, and urinary tract infection. 4. The clinical efficacy rate was 100% with 18 excellent responses and 3 good responses. 5. The bacteriological efficacy rate was 90.9% in eradication rate, based on results on 17 strains of suspected causative microorganism among which 10 strains were eradicated, 1 strain was decreased, and 6 strains were unknown. 6. There was no side effect during the treatment and after the discontinuation, while, in clinical laboratory tests, GOT and GPT were elevated in 1 case which was judged as abnormal. No patient refused the drug. CPDX-PR was considered to be very useful drug because of its excellent efficacy and safety in pediatrics in treating infectious diseases.

A multicenter study was conducted in which the in vitro activity of cefpodoxime (the active metabolite of the prodrug ester cefpodoxime proxetil) was compared with those of cefixime, cefuroxime, cefaclor, cefadroxil, and clarithromycin against 5556 recent clinical isolates. Cefpodoxime demonstrated potent activity against members of the Enterobacteriaceae, in particular against species generally resistant to the established oral cephalosporins such as Proteus vulgaris [minimum inhibitory concentration (MIC)50, 0.12 microgram/ml], Providencia rettgeri (MIC50, 0.015 microgram/ml), and Serratia marcescens (MIC50, 2 micrograms/ml). Cefpodoxime was very effective against the fastidious organisms most frequently associated with respiratory infections, such as Streptococcus pneumoniae (MIC90, 0.12 microgram/ml), Haemophilus influenzae (MIC90, 0.12 microgram/ml), and Moraxella catarrhalis (MIC90, 1 microgram/ml). In contrast to other orally administrated third-generation cephalosporins (cefixime or ceftibuten), cefpodoxime demonstrated reasonable activity against oxacillin-susceptible staphylococci, with MIC50 ranging from 1 to 2 micrograms/ml buy vantin online . All cephalosporins tested demonstrated poor activity against Pseudomonas spp., Xanthomonas spp., Enterococcus spp., and oxacillin-resistant staphylococci. Cefpodoxime had the widest spectrum of activity of all tested oral cephalosporins.

One hundred sixty-three women with uncomplicated acute lower urinary tract infections were included in a multicenter randomized study comparing cefpodoxime-proxetil (one 100-mg tablet twice daily) with trimethoprim-sulfamethoxazole (one double-strength tablet [160/800 mg] twice daily) for 3 days. A total of 30 women in both arms were excluded from the study for various reasons. buy vantin online At 4 to 7 days after the discontinuation of therapy, 62 of 63 (98.4%) cefpodoxime-proxetil recipients and 70 of 70 (100%) trimethoprim-sulfamethoxazole patients were clinically cured and demonstrated bacteriological eradication, respectively. At 28 days after treatment, 48 of 55 (87.3%) and 43 of 50 (86%) cefpodoxime-proxetil recipients as well as 51 of 60 (85%) and 42 of 50 (84%) trimethoprim-sulfamethoxazole recipients were clinically cured and demonstrated bacteriological eradication, respectively. Independently of the prescribed regimen, a significant difference (P < 0.001) in failure rates was observed only for patients with a previous history of three or more episodes of acute cystitis per year. With the exception of one patient in the trimethoprim-sulfamethoxazole arm who discontinued therapy because of gastrointestinal pain, both antimicrobials were well tolerated. In conclusion, cefpodoxime-proxetil treatment for 3 days was as safe and effective as trimethoprim-sulfamethoxazole for 3 days for the treatment of uncomplicated acute cystitis in women.

vantin drug classification 2016-10-24

Antimicrobial resistance among organisms that cause acute otitis media (AOM) and new approaches in the prevention and treatment of AOM are discussed. Organisms commonly responsible for causing AOM include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. The evolution of pneumococcal resistance to penicillins, erythromycin, trimethoprim-sulfamethoxazole, and oral cephalosporins may require treatment with agents such as vancomycin or rifampin in certain patients. H. influenzae and M. catarrhalis are becoming increasingly resistant to penicillins, trimethoprim-sulfamethoxazole, oral cephalosporins, and macrolides. Mechanisms of resistance include changes in penicillin-binding proteins, production of beta-lactamase, alterations in target enzymes, and inhibition of drug access to the site of action. Because of changing resistance patterns and the limited spectra of activity of many currently available antimicrobials, new buy vantin online antimicrobials have been developed in the hope of improving therapy. While amoxicillin and trimethoprim-sulfamethoxazole are appropriate first-line agents, children at risk for resistant infections may be treated initially with cefuroxime axetil, cefpodoxime proxetil, cefprozil, or amoxicillin-clavulanate. After local resistance patterns, patient adherence to therapy, in vitro data, and cost factors have been weighed, other agents to consider include loracarbef, clarithromycin, azithromycin, and ceftriaxone. Along with the efforts to improve treatment, research is focusing on the prevention of otitis media with bacterial and viral vaccines. The emergence of resistant strains of organisms causing AOM has complicated its treatment.

CS-807 is a new oral prodrug of R-3746, a cephalosporin derivative, with potent in vitro and in vivo antibacterial activity against both gram-positive and gram-negative bacteria. The susceptibility of about 1,200 clinical buy vantin online isolates to R-3746 was determined by the agar dilution method. Ninety percent or more of pathogens such as Staphylococcus aureus, streptococci, Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, indole-positive and indole-negative Proteus spp., Providencia rettgeri, and Haemophilus influenzae were inhibited at concentrations ranging less than or equal to 0.01 to 1.56 micrograms/ml. Furthermore, at a concentration of 3.13 micrograms/ml, 50% or more of Staphylococcus epidermidis, Morganella morganii, Citrobacter freundii, and Serratia marcescens strains were also inhibited. Pseudomonas aeruginosa and Xanthomonas maltophilia were resistant to R-3746. The activity of R-3746 was scarcely influenced by several growth conditions. R-3746 was highly resistant to hydrolysis by beta-lactamases derived from various species of bacteria. Killing-curve studies demonstrated bactericidal activity of R-3746 at concentrations above the MIC. R-3746 showed high affinity for penicillin-binding proteins 1, 3, and 4 of Staphylococcus aureus and 1A, 1Bs, and 3 of Escherichia coli. Systemic infections in mice caused by various pathogens, including beta-lactamase-producing strains, responded well to therapy with oral doses of CS-807.

Cefpodoxime proxetil (CPDX-PR, CS-807) dry syrup was administered orally to 31 patients with various infections at daily dose levels between 5.4 and 10.9 mg/kg divided into three doses. 1. The subjects were 3 patients with urinary tract infections, 25 with tonsillitis and 1 patient each with bronchitis, pneumonia, and cervical lymphadenitis. Clinical effects were excellent in 16 cases, good in 14, and fair in 1 (tonsillitis), with an overall efficacy rate of 96.8%. 2. Organisms suspected as pathogens were 32 strains (6 strains of Staphylococcus aureus, 2 of Streptococcus pyogenes, 1 of Enterococcus faecalis, 15 of Haemophilus influenzae, 5 of Haemophilus parainfluenzae and 3 of Escherichia coli). Bacteriologically, eradication of pathogens were observed in 30 strains, decrease in one (H. parainfluenzae), and no change in another (E. faecalis), thus the eradication rate was 93.8%. 3. Side effect was observed in 1 case (slight eruption buy vantin online ) but it was possible continue the treatment. Abnormal laboratory test values were observed in 1 case of a slight prolongation of prothrombin time and eosinophilia, but they were not serious. Diarrhea was not observed in any patients. 4. All the medication was done on schedule. No refusal of the drug occurred due to its taste or odor.

The pharmacokinetic, economic and practical aspects of sequential therapy with iv and oral cephalosporins are reviewed. New broad spectrum oral cephalosporins, such as cefixime, cefpodoxime proxetil and cefetamet pivoxil achieve serum concentrations above the MICs for most Enterobacteriaceae for at least as long as for parenteral cefuroxime. Substantial cost reductions are possible with an early switch from iv to oral cephalosporins. The clinical studies that have been performed so far have important shortcomings. Well designed clinical studies are necessary to prove the feasibility of sequential buy vantin online therapy with cephalosporins for serious infections in hospitalized patients.

The evaluation of seven widely-used antibiotic preparations [five cephem antibiotics; cefaclor (CCL), Cytoxan 50 Mg cefpodoxime proxetil (CPDX-PR), cefdinir (CFDN), cefditoren pivoxil (CDTR-PI), cefcapene pivoxil (CFPN-PI), one macrolide; clarithromycin (CAM) and one penem; faropenem sodium (FRPM)] for children were performed from a standpoint of water-solubilities, both as a preparation and as a component drug. As the results, these preparations showed great differences in the water-solubilities when added 10 ml water to 0.5 g of each preparation. That is, their solubilities differed from about 40% (CFPN-PI) to 100% (FRPM) as a preparation, and from nearly 0% (CAM) to 100% (FRPM, CCL) as a component drug. Additionally, about a half of the insoluble residues were found to be the component drug, in the cases of three preparations (CPDX-PX, CFDN, CDTR-PI) which were solubilized at 80-90%. From these results, it was suggested that the marketed antibiotic preparations for children might be classified into three categories; i.e., [A] preparation for solution and suspension (FRPM, CCL), [B] preparation suitable to suspension (CPDX-PR, CFDN, CDTR-PI), and [C] fine granule preparation for children unsuitable to suspension (CFPN-PI, CAM). Consequently, the names for dosage-forms of these preparations should be standardized.

Carboxylesterases (CE) are ubiquitous enzymes responsible for the detoxification of xenobiotics. Many therapeutically useful drugs are metabolized by these proteins which impacts upon the efficiency of drug treatment. In some instances, CEs convert inactive prodrugs to active metabolites, a process that is essential for biological activity. Such compounds include the anticancer agents CPT-11 (3) and capecitabine (4), the antibiotics Ceftin (9) and Vantin, as well as the illicit street drug heroin (6). However, more commonly, CEs hydrolyze many esterified drugs to inactive products that are then excreted. Agents such as flestolol (11), meperidine (5), lidocaine (8) and cocaine (7), are all hydrolyzed and inactivated by these enzymes. Therefore the efficacy of esterified drugs will be dependent upon the distribution and catalytic activity of different CEs. In this review, we examine the structural aspects of CEs and their roles in drug detoxification Geodon Maximum Dose and propose that modulation of CE activity may allow for improvements in, and potentiation of, drug efficacy.

The study enrolled 851 patients. Comparable clinical cure rates were observed among Viagra 400 Mg evaluable patients in the 3 treatment groups at both the posttreatment and followup visits: at the posttreatment visit, cure rates were 90.5% (162/179) for cefditoren 200 mg, 89.7% (148/165) for cefditoren 400 mg, and 92.2% (153/166) for cefpodoxime 200 mg; at the follow-up visit, they were a respective 88.4% (160/181), 87.2% (143/164), and 90.4% (151/167). Of the 171 strains of Streptococcus pneumoniae isolated before treatment, 22 (12.9%) had reduced susceptibility to penicillin, 5 (2.9%) of them penicillin resistant (minimum inhibitory concentration > or = 2 microg/mL). At the posttreatment visit, the overall eradication rates of pathogens isolated from microbiologically evaluable patients were 88.7% (134/151), 89.9% (134/149), and 95.7% (134/140) in the respective treatment groups (P = 0.031, cefditoren 200 mg vs cefpodoxime). Eradication rates of S pneumoniae were 93.8% (45/48), 95.7% (45/47), and 95.6% (43/ 45) in the respective treatment groups; those of Haemophilus influenzae were 90.2% (46/51), 97.7% (43/44), and 97.4% (37/38). The rates of resolution and/or improvement in clinical signs and symptoms were comparable between groups. The study drugs were well tolerated, with 1.7%, 2.5%, and 1.4% of patients in the respective groups discontinuing study drug prematurely due to a treatment-related adverse event, the majority of these associated with the digestive system.

Self-nanoemulsifying drug delivery systems (SNEDDS) were developed with the objective to overcome problems associated with the Imdur Medication Uses delivery of cefpodoxime proxetil (CFP), a poorly bioavailable high dose antibiotic having pH dependant solubility. Solubility of CFP in oily phases and surfactants was determined to identify components of SNEDDS. Various surfactants and co-surfactants were screened for their ability to emulsify selected oily phases. Ternary phase diagrams were constructed to identify area of nanoemulsification for the selected systems. The influence of CFP and the pH of dilution medium on the phase behavior of selected system were assessed. The globule size of optimized CFP SNEDDS in various dissolution media was determined to check the effect of pH on its behavior. The optimized CFP SNEDDS needed surfactant content less than 40% and yielded nanoemulsion of mean globule size 170 nm, which was not affected by the pH of dilution medium. The optimized SNEDDS released CFP completely within 20 min irrespective of the pH of dissolution medium.

Cefpodoxime proxetil, a new oral cephalosporin, is the prodrug ester of cefpodoxime. Minimal inhibitory concentrations (MIC) of RU 51746 (sodium salt of cefpodoxime: CPD) were evaluated by agar dilution for 1 696 bacterial strains isolated in 5 hospitals. For Enterobacteriaceae, MIC 50 and 90% were respectively (micrograms/ml): (1) naturally non bêtalactamase producing species: E. coli, Shigella and Salmonella Flonase Generic Cost 0.25-0.5; P. mirabilis 0.06-0.12. (II) chromosomal penicillinase producing species: Klebsiella 0.12-1. (III) chromosomal cephalosporinase producing species: E. cloacae and C. freundii 2-greater than 128; S. marcescens 2-64; indole + Proteus 0.25-64; P. stuartii 0.25-16. Activity of CPD was not modified on plasmid mediated penicillinase producing strains, but CPD was inactive on cephalosporinase hyperproducing strains, and on broad spectrum bêtalactamases producing strains. CPD was inactive on P. aeruginosa (MIC greater than or equal to 64) and on A. baumannii (16-pi 128). Haemophilus, regardless on bêtalactamase production status, were very susceptible to CPD (MIC less than or equal to 0.25) and B. catarrhalis was generally inhibited by 0.12 to 1. CPD was poorly active on methicillin susceptible Staphylococci (MIC 50 and 90%: 2-4) and inactive on methicillin resistant strains. Enterococci and Listeria monocytogenes were generally resistant; Streptococci A, B, C, G and Pneumococci were inhibited by low concentration: 0.002 to 0.25 (MIC 50 and 90%: 0.016-0.032) whereas MIC for other Streptococci were 0.004 to 32 (MIC 50 and 90%: 0.25-4). These antibacterial properties placed CPD in excellent position among oral cephalosporins.

Upper respiratory tract infections in children are common and usually self-limiting conditions, which include acute otitis media (AOM), acute rhinosinusitis (ARS), and acute pharyngitis (AP). Management of pediatric AOM considers observation strategy for selected and uncomplicated cases, older than 2 years of age, only when adequate follow-up can be ensured. Otherwise, an antibiotic treatment should be prescribed. Amoxicillin should be preferred as the first-choice therapy. Switch therapy to ceftriaxone is suggested if amoxicillin regimen failure occurs within 48-72 hours. The diagnosis of ARS is established by the persistence of purulent nasal of post-nasal draining Imdur Heart Medicine lasting at least 10 days especially if accompanied by supporting symptoms and signs. Amoxicillin is the first choice drug for mild ARS in children. When symptoms persist or worsen, amoxicillin/clavulanate or cefpodoxime proxetil, or ceftriaxone are recommended. Clinical criteria alone are not sufficiently accurate in children with AP to distinguish bacterial and viral etiology. Thus microbiological evaluation is needed and positive throat culture or rapid antigen detection test are required to establish the diagnosis of streptococcal pharyngitis and consequently to prescribe antibiotic treatment. The first choice treatment in European countries still remains amoxicillin or amoxicillin/clavulanate.

Six newly developed oral cephem antibiotics, which included 5 with an aminothiazolyl side chain, viz., cefixime, cefotiam hexetil, cefpodoxime proxetil, cefteram pivoxil, ceftibuten, and one with a conventional side chain design, BMY 28100, were tested for their antimicrobial activities. Three traditional oral beta-lactam antibiotics, ampicillin, cephalexin, and cefaclor, were used as reference antibiotics. The 5 aminothiazolyl cephems were more active than the reference drugs against clinical isolates of Escherichia coli, Klebsiella pneumoniae and Haemophilus influenzae. All 6 new drugs showed poor activity against clinical isolates of Enterobacter cloacae, Pseudomonas aeruginosa, and enterococci. They were better than cephalexin and cefaclor, but slightly poorer than or the same as ampicillin in activities against Streptococcus pyogenes and Streptococcus pneumoniae. Cefotiam hexetil, BMY 28100, and cefpodoxime proxetil were also more active than cephalexin against Staphylococcus aureus. Although the 6 tested new oral cephems demonstrated little difference in their activities against different bacteria, they all showed greater antimicrobial activity than the traditional oral antibiotics now in clinical use.

In order to compare the clinical efficacy and safety of cefatrizine (Cefaperos) and cefpodoxime proxetil (Orelox) in the treatment of secondarily infected chronic obstructive pulmonary disease (COPD) in adults, a multicentre, randomized, open study was conducted by 60 general practitioners in two parallel groups of patient suffering from COPD complicated by an acute episode of superinfection (Anthoniesen stages 2 and 3). After verification of the eligibility criteria, written consent and randomization, the patients received, for 10 days, either cefatrizine at the dose of 1 g/day or cefpodoxime proxetil at the dose of 400 mg/day. A self-assessment form was given to the patient. A telephone visit was planned for D3. The final visit on D11 +/- 1 evaluated clinical efficacy (success or failure) and safety. The study population was composed of 250 patients with a mean age of 59.9 +/- 15.9 years (sex ratio M/F = 1.5). The principal etiology of COPD was chronic bronchitis in 67.5% of patients, longstanding asthma in 24.5% and emphysema in 6.8%. The mean history of the disease was 13.0 +/- 10.8 years. The Anthoniesen score was equal to 2 in 73.6% of patients, 3 in 8.8% of patients and 1 in 17.6% of patients. No significant difference concerning these criteria was observed between the two study groups. The clinical success rate was equivalent in the two groups. The time to regression of clinical signs tended to be shorter, up until the sixth day (mainly between D4 and D6) for patients treated with cefatrizine (p = 0.09; NS). The clinical safety was considered to be good and was comparable in the two study groups. This study concluded on the equivalent clinical efficacy of cefatrizine and cefpodoxime proxetil in the treatment of superinfections of COPD in general practice (97.5% and 99%, respectively), with a satisfactory and comparable safety, but with a much lower cost of treatment for cefatrizine. This conclusion is particularly important in the context of opposable medical references, as, although the treatment of superinfections of COPD by second and third generation cephalosporins is frequently proposed, the prescription of a less expensive cephalosporin appears to be more relevant.

We have carried out laboratory and clinical studies on cefpodoxime proxetil (CS-807, CPDX-PR). The results are summarized as follows. CPDX-PR was given via oral administration to each 2 children at a single dose of 3 mg/kg and to each of 3 children in a 100 mg tablet. After the oral administration, mean peak serum levels of CPDX obtained for the 2 dose levels were 1.86 +/- 0.35 micrograms/ml and 2.16 +/- 0.63 micrograms/ml at 2 hours, respectively, and mean half-lives were 1.31 +/- 0.02 hours and 1.47 +/- 0.18 hours, respectively. The mean urinary excretion rate of CPDX was 32.8 +/- 1.0% in the first 12 hours after the oral administration of 3 mg/kg. When a dose of 100 mg tablet was given to each of the 3 children, urinary excretion rates in the first 12 hours were 43.5%, 48.6% and 24.8%, respectively. Treatment with CPDX-PR was done in 38 cases of pediatric bacterial infections; 19 cases of tonsillitis, 3 cases of pharyngitis, 1 case of bronchitis, 3 cases of pneumonia, 3 cases of scarlet fever, 2 cases of impetigo, 4 cases of UTI and 1 case each of phlegmone, subcutaneous abscess and balanitis. Results obtained were excellent in 23 cases, good in 15 cases. No significant side effect due to the drug was observed in any cases.

Overall clinical cure (defined as not requiring antimicrobial treatment during follow-up) at the 30-day follow-up visit. Secondary outcomes were clinical and microbiological cure at the first follow-up visit and vaginal Escherichia coli colonization at each follow-up visit. The hypothesis that cefpodoxime would be noninferior to ciprofloxacin by a 10% margin (ie, for the difference in the primary outcome for ciprofloxacin minus cefpodoxime, the upper limit of the confidence interval would be <10%) was formulated prior to data collection.

The aim of this study is to develop a simple and applicable HPLC method for the detection of cefpodoxime acid (CFA) in rabbit plasma after oral administration of cefpodoxime proxetil (CFP) loaded chitosan-alginate (CH-ALG) beads formulation. CFP is a prodrug that is deesterified in vivo to its active metabolite CFA to exhibit antibiotic activity. Chromatographic separation of CFA and internal standard (IS) was achieved by a RP18(C18), Phenomenax®100, (250×4.6mm) with the mobile phase consisting of (0.02mol/l (20mM) ammonium acetate solution and acetonitrile (92:8, v/v, pH=4.6) at a flow rate of 1.0ml/min. The method was validated according to the requirements of US-FDA guidelines for bioanalytical method validation. The linear regression analysis for the calibration plots showed good linear relationship (R(2)=0.9905) in the working concentration range of 0.5-50μg/ml. The limits of detection and quantification (S/N=3) were 0.069 and 0.136μg/ml. Plasma CFA levels were successfully determined in rabbit with satisfactory precision and accuracy. The analyte was found to be stable after a number of stability studies. The proposed HPLC method was successfully applied to pharmacokinetic study in rabbits for CFP loaded CH-ALG beads and marketed immediate release (IR) tablets. All pharmacokinetic parameters were assessed.

Compound U-76,252 (Upjohn) is a cephalosporin ester that enhances oral absorption of the active free acid cephem, U-76,253. The active form structurally resembles parenteral aminothiazolyl-methoxyimino cephalosporins such as cefotaxime and its desacetyl metabolite. The g-negative antimicrobial activity of U-76,253 A (sodium salt of U-76,253) was most similar to that of cefixime and more potent than that of cefaclor or cefuroxime among the orally administered cephalosporins. Against g-positive bacteria, U-76,253 A was more active than cefixime. U-76,253 A was relatively stable to hydrolysis by five beta-lactamases (Type Ia, TEM-1, K1, CARB-2, and OXA-1), a stability most similar to cefotaxime and superior to that of cefaclor. Only the Type Ia (P99) enzyme was significantly inhibited by U-76,253 (IC 50 = 2.0 microM).

A number of oral third-generation cephalosporins (cefixime, cefetamet pivoxil, ceftibuten and cefpodoxime proxetil) have been widely trialled and are becoming available. In addition, cefdinir may also be marketed. Compared with first- and second-generation agents, the oral third-generation cephalosporins have an improved antibacterial spectrum and reduced minimum inhibitory concentrations against common Gram-negative pathogens. In contrast, with the exception of cefdinir, they are less active against Staphylococcus aureus. They have favourable pharmacokinetic profiles and are generally administered in once- or twice-daily regimens. They are well tolerated, but cefixime has been associated with a particularly high rate of diarrhoea. Possible clinical indications for the use of oral third-generation cephalosporins include upper and lower respiratory, genitourinary and soft-tissue infections and follow-on treatment of severe infections requiring hospitalisation. At present, these drugs offer no particular clinical advantages over standard therapy in most circumstances. However, they may be considered where there is hypersensitivity to penicillins, a high incidence of resistance to first-line therapy in the community, or failure of standard therapy. Further studies are needed to define the efficacy of oral third-generation agents in the prevention of rheumatic fever and as follow-on therapy for severe infections. The oral third-generation cephalosporins are generally more expensive than standard agents, but detailed studies that include extended costs (e.g. treatment of adverse effects, treatment of clinical failure, return visits to physicians) have yet to be reported.

The pharmacokinetics, bacteriological and clinical efficacy, and safety of the suspension formulation of cefpodoxime proxetil, an oral cephalosporin antibacterial, were evaluated in paediatric patients with various infections. With single doses of 3 and 6 mg/kg (cefpodoxime equivalent) a dose response was evident in the serum concentration values. Absorption, as evidenced by serum concentrations and areas under the concentration-time curve, was enhanced when the suspension was administered before a meal. The overall clinical efficacy (defined as an excellent or good response) in evaluable patients (those from whom a pathogen was isolated) was 94.7% (451 of 476). Bacteriological eradication rates were as follows: Gram-positive bacteria 91.3%; Gram-negative bacteria 88.6%, and 90.0% overall. Side effects occurred in 17 (2.29%) patients, and transient and reversible abnormal laboratory values were found in a few patients.

A total of 220 adults and children > 10 years old (mean 29.5 +/- 11.7 years) with pharyngitis/tonsillitis were randomized to receive either cefpodoxime proxetil 100 mg bid for 5 days (n = 113) or phenoxymethyl penicillin, 600 mg tid for 10 days (n = 107). At the end of treatment of the 166 evaluable patients, a satisfactory clinical response was obtained in 85/88 (96.6%) patients treated with cefpodoxime proxetil and in 75/78 (96.1%) treated with phenoxymethyl penicillin. Group A beta-hemolytic streptococci (GABHS) eradication was similar in both groups: 79/82 (96.3%) patients in the cefpodoxime proxetil group and 64/68 (94.1%) patients in the phenoxymethyl penicillin group. At follow-up (20-30 days after the end of treatment) the GABHS eradication persisted in 67/72 (93.1%) patients treated with cefpodoxime proxetil and in 56/61 (91.8%) patients treated with phenoxymethyl penicillin. Significantly better compliance (p < 0.01) was noticed with the cefpodoxime proxetil regimen compared with the phenoxymethyl penicillin regimen, with only 2/110 (2%) poorly compliant patients in the cefpodoxime proxetil group vs 17/104 (16%) in the phenoxymethyl penicillin group. Thus, the shorter duration of therapy, in conjunction with demonstrated clinical and bacteriological efficacy that is equivalent to standard therapy, makes cefpodoxime proxetil an acceptable alternative for the treatment of GABHS pharyngitis/tonsillitis.
