A significant increase in PWV was observed in both glipizide (mean (SEM) change at 24 months 2.8 (2.7) m/s, p = 0.012) and metformin (2.2 (0.7) m/s, p = 0.01) groups during the follow up period. In contrast, PWV remained unchanged in the placebo group. The increase in PWV in the treatment groups was significant compared with placebo (analysis of variance p < 0.05). Other cardiovascular or metabolic variables did not change significantly compared with placebo during follow up.

Nateglinide is a short-acting, pancreatic, beta-cell-selective, K(ATP) potassium channel blocker that improves overall glycemic control in type 2 diabetes. Although nateglinide's mechanism of action is related to that of sulphonyl-ureas and repaglinide, important differences do exist. Nateglinide binds rapidly to the sulfonylurea SUR1 receptor with a relatively low affinity, and it dissociates from it extremely rapidly in a manner of seconds. This rapid association and dissociation gives nateglinide a unique "fast on-fast off" effect. Thus, nateglinide has a rapid onset and short duration of action stimulating insulin secretion in vivo and providing good control of postprandial hyperglycemia when taken immediately prior to meals. The rapid action of nateglinide on the beta cells stimulates and restores the normal physiological first and early phase of insulin secretion, consequently reducing postprandial hyperglycemia. This hypoglycemic effect of nateglinide leads to improved glycemic control, while the short duration avoids delayed hyperinsulinemia and hypoglycemia after meals. Nateglinide is not a sulfonylurea, but it shares the mechanism of action of commonly used oral hypoglycemic agents such as glibenclamide and glipizide. Like the recently introduced, short-acting agent, repaglinide, it does not incorporate a sulfonylurea moiety. However, nateglinide's effects on insulin secretion and glycemic control differ significantly from the sulfonylureas and repaglinide in that it preferentially stimulates acute phase insulin, better controls postprandial glucose excursions and spikes, and causes less hyperinsulinemia and hypoglycemia. Compounds with such a profile should not only achieve improved overall glucose control, but also reduce the risk of vascular complications which is the most important feature of nateglinide. Clinical studies with nateglinide have confirmed that it acts rapidly and both restores insulin release and attenuates the postprandial glucose spike. Nateglinide is both effective and well tolerated in the treatment of type 2 diabetes. The reported overall profile of adverse effects appears to be superior to that of other K(ATP) potassium channel blockers, the glucose modulator metformin and PPARgamma agonists such as troglitazone. Clinical comparisons of these agents have shown nateglinide to be more effective in attenuating postprandial glucose than any other oral hypoglycemic agent, and that treatment with both nateglinide and metformin provides additive effects that afford improved control of plasma glucose levels. The administration regimen for nateglinide, immediately prior to meals, also facilitates patient compliance. (c) 2001 Prous Science. All rights reserved.

These data support the importance of early insulin release in type 2 diabetes mellitus and indicate that, independent of the level of insulin resistance, stimulating insulin release early and briefly provides for more effective and tighter glycaemic control than increasing insulin exposure to a greater magnitude later.

Glypizide and i.v. tolbutamide were administered to a series of diabetics. On different days, 10 subjects (controls for themselves) received 1 mg glypizide anal 100 mg tolbutamide; a further 10 received 2 mg glypizide and 200 mg tolbutamide. Blood sugar and insulin and NEFA values were determined every 10' for one hour after the injection. It was found that the hypoglycaemising activity of glypizide was about 140 times that of tolbutamide. It also caused a greater incretion of insuline and a more marked reduction of NEFA.

A total of 160 newly diagnosed patients with fasting glucose 7.0-13.0 mmol/L and body mass index <30 kg/m(2) from five centres in China were randomized to metformin or glipizide GITS for 24 weeks. Early insulin secretion [the ratio of area under the curve (AUC) of insulin to glucose during 0-30 min (InsAUC30 /GluAUC30 )] and insulin sensitivity [Matsuda index (ISIM )] were assessed during the standard meal tolerance test before and after therapy. Plasma glucagon-like peptide-1(GLP-1) and glucagon levels were also measured.

We studied 44 elderly men with diabetic nephropathy who participated in a clinical trial. Glomerular filtration rate and renal plasma flow were measured by continuous infusion technique with five urine collection periods on two occasions 4 months apart. Protein and creatinine excretion rates were measured in the same specimens. In addition, two consecutive 24-hour specimens every month for 4 months were collected to analyze urine protein, creatinine, urea nitrogen, and electrolytes. A hierarchical random effects model was used to analyze the reproducibility from hour to hour, from day to day, and from month to month.

A solid self-nanoemulsifying drug-delivery system (solid SNEDDS) has been explored to improve the solubility and dissolution profile of glipizide. SNEDDS preconcentrate was systematically optimized using a circumscribed central composite design by varying Captex 355 (Oil), Solutol HS15 (Surfactant) and Imwitor 988 (Co-surfactant). The optimized SNEDDS preconcentrate consisted of Captex 355 (30% w/w), Solutol HS15 (45% w/w) and Imwitor 988 (25% w/w). The saturation solubility (SS) of glipizide in optimized SNEDDS preconcentrate was found to be 45.12 ± 1.36 mg/ml, indicating an improvement (1367 times) of glipizide solubility as compared to its aqueous solubility (0.033 ± 0.0021 mg/ml). At 90% SS, glipizide was loaded to the optimized SNEDDS. In-vitro dilution of liquid SNEDDS resulted in a nanoemulsion with a mean droplet size of 29.4 nm. TEM studies of diluted liquid SNEDDS confirmed the uniform shape and size of the globules. The liquid SNEDDS was adsorbed onto calcium carbonate and talc to form solid SNEDDS. PXRD, DSC, and SEM results indicated that, the presence of glipizide as an amorphous and as a molecular dispersion state within solid SNEDDS. Glipizide dissolution improved significantly (p < 0.001) from the solid SNEDDS (∼100% in 15 min) as compared to the pure drug (18.37%) and commercial product (65.82) respectively.

Nateglinide (A-4166) is an amino acid derivative with insulinotrophic action in clinical development for treatment of type 2 diabetes. The aim of this study was to determine whether nateglinide's interaction at the K(ATP) channel/sulfonylurea receptor underlies its more rapid onset and shorter duration of action in animal models. Binding studies were carried out with membranes prepared from RIN-m5F cells and HEK-293 cells expressing recombinant human sulfonylurea receptor 1 (SUR1). The relative order for displacement of [(3)H]glibenclamide in competitive binding experiments with RIN-m5F cell membranes was glibenclamide > glimepiride > repaglinide > glipizide > nateglinide > L-nateglinide > tolbutamide. The results with HEK-293/recombinant human SUR1 cells were similar with the exception that glipizide was more potent than repaglinide. Neither nateglinide nor repaglinide had any effect on the dissociation kinetics for [(3)H]glibenclamide, consistent with both compounds competitively binding to the glibenclamide-binding site on SUR1. Finally, the inability to measure [(3)H]nateglinide binding suggests that nateglinide dissociates rapidly from SUR1. Direct interaction of nateglinide with K(ATP) channels in rat pancreatic beta-cells was investigated with the patch-clamp method. The relative potency for inhibition of the K(ATP) channel was repaglinide > glibenclamide > nateglinide. Kinetics of the inhibitory effect on K(ATP) current showed that the onset of inhibition by nateglinide was comparable to glibenclamide but more rapid than that of repaglinide. The time for reversal of channel inhibition by nateglinide was also faster than with glibenclamide and repaglinide. These results suggest that the unique characteristics of nateglinide are largely the result of its interaction at the K(ATP) channel.

We prospectively followed Veterans Health Administration patients with type 2 diabetes initiating treatment with an OHA and not receiving any other diabetes pharmacotherapy for at least one year. Information on OHAs, weight, co-morbidities, other medications, demographics, and laboratory measurements was obtained from electronic medical records. Logistic regression was used to estimate 5-year mortality odds by weight change during the first year after OHA treatment initiation.

We provide the first evidence on the pharmacokinetics and pharmacodynamics of sulfonylurea derivatives in human MODY subjects. The half-life of glipizide did not change, and reached 3.8±0.7 and 3.7±1.8 h in the MODY and control subjects, respectively. The half-life of glibenclamide was increased only in some MODY subjects (t1/2 9.5±6.7 and 5.0±1.4 h, respectively). Importantly, the intra- individual responses of MODY (but control) subjects to glipizide and glibenclamide treatment were highly correlated. With regards to pharmacodynamics, we observed a differential response of control but not MODY subjects to the doses of glipizide and glibenclamide applied.

Diabetic patients who had fasting hyperinsulinemia (n = 53, 100%) had blood pressure > or = 140/90 at the time of presentation. Patients who had fasting serum insulin within normal range only 30% (n = 17) had hypertension. Patients of group one had good recovery from hyperglycemia and reduction in triglyceride values when treated with sulphonylurea (subgroup A) as compared to patients treated with biguanide (subgroup B). On the contrary patients of group two showed poor glycemic control, increase in blood pressure and rise in serum triglyceride titre when treated with sulphonylurea (subgroup A) while in the same group biguanide effectively produced euglycemia with normalization of blood pressure and decrease in triglyceride levels (subgroup B).

Sodium was measured in rat pancreatic islet exposed to tolbutamide, glipizide, diazoxide or sulfisomidine. When added to a medium with physiologically balanced cations these sulphonamides induced a significant rise of the islet content of sodium. The insulin-releasing compounds, tolbutamide and glipizide, had effects opposite to those of the hyperglycemic diazoxide in counteracting the increase of sodium obtained with removal of K+. The tolbutamide-induced increase in sodium was reversed to a decrease when Ca2+ was omitted from the incubation medium. The increase of sodium, which was also seen with non-hypoglycemic sulphonamides, is itself not sufficient for initiating insulin release. However, it may well represent an important mechanism contributing to the secretory response initiated by Ca2+ entry into the sulfonylurea-depolarized beta-cell.

This randomized, double-blind, placebo-controlled study (NCT01020123) was conducted over 4 months with an optional 2-month extension. Patients (n = 458) with HbA1c 7.5-10% were randomized to AZD1656 20 mg (n = 40) or 40 mg (n = 52) fixed doses or 10-140 mg (n = 91) or 20-200 mg (n = 93) titrated doses, placebo (n = 88) or glipizide 5-20 mg titrated (n = 94). Patients (n = 72) with HbA1c >10 and ≤12% received open-label AZD1656 (20-200 mg titrated). Primary outcome was placebo-corrected change in HbA1c from baseline to 4 months of treatment.

The effects of the first generation sulphonylurea compound gliclazide and the second generation sulphonylurea compound glipizide on strophanthidin toxicity was investigated in rabbits. The sulphonylurea pretreated animals were intravenously infused with 23 mumol/kg strophanthidin until the appearance of the first ventricular ectopic beat and continued thereafter until the appearance of ventricular fibrillation. The first generation sulphonylurea gliclazide increased, while the second generation sulphonylurea glipizide decreased the strophanthidin toxicity in a dose dependent manner. It was concluded that instead of first generation sulphonylureas, second generation sulphonylureas must be preferred in cardiac glycoside treated diabetics, when sulphonylurea treatment is necessary.

Insulin action was assessed by measuring insulin-mediated glucose disposal (KI) in 13 non-ketotic diabetic patients both before treatment and after normalization of plasma glucose by diet (5 patients) or sulfonylurea (glipizide) therapy (8 patients). While the KI of the diet-treated group was unchanged by therapy, that of the glipizide-treated group was significantly increased. The data show that chronic glipizide therapy is associated with a potentiation of insulin action, which may account for the major anti-diabetic effect of this drug.

Use of fenofibrate or gemfibrozil together with glyburide was associated with elevated overall risks of serious hypoglycaemia. CYP inhibition seems unlikely to explain this observation. We speculate that a pharmacodynamic effect of fibrates (e.g. activate peroxisome proliferator-activator receptor alpha) may contribute to these apparent interactions.

Indirect evidence suggests that sulfonylureas, in addition to stimulating insulin release, exert additional effects at extrapancreatic levels which are of value in the management of type 2 diabetes. In order to characterize in vivo some of these effects, insulin sensitivity was studied in 9 type 1 diabetics with no residual insulin secretory activity, during treatment with chlorpropamide (250 mg b.i.d. for 8 days) and with glipizide (5 mg t.i.d. for 8 days). Employing the glucose clamp technique with the aid of an artificial pancreas (Biostator), glucose disposal during insulin infusion (0.1 U buy glucotrol online /kg in 60 min) was calculated by the amount of glucose required to keep the blood glucose at preinfusion levels. Chlorpropamide and glipizide administration was accompanied by a significant increase of the amount of glucose required to clamp blood glucose levels, while serum (free) insulin levels were superimposable during the different clamping studies. In the absence of endogenous insulin release, these data strongly suggest that the two sulfonylureas employed enhance in vivo the peripheral sensitivity to insulin. Further studies are required to indicate a preferential site of action (liver, muscle, adipose tissue) of sulfonylureas.

Based on the in vitro blockade of adrenal catecholamines release by sulfonylurea, we searched for an anti-stress activity of this drug. Stress- buy glucotrol online induced hyperglycemia and insulin inhibition were employed as adrenergic stress indicators. A standard dose of the oral sulfonylurea glipizide (200 micrograms/100 g), administered 15 min before a 1-h restraint stress to intact or 80% pancreatectomized rats, produced total suppression of the stress-induced hyperglycemia-hypoinsulinemia, an effect followed by a significant post-stress hypoglycemia of 1 h duration. The latter effect was elicited by all the sulfonylureas assayed. In the 80% pancreatectomized rats, glipizide nearly halved the increases in plasma catecholamines at 30 min of stress, but did not modify those attained at 60 min, when glycemia was decreasing and insulinemia was still increasing. Moreover, behavioral experiments in intact stressed rats showed that the adrenergic overt behavior inhibition caused by propranolol was not produced either by glipizide or insulin, reinforcing that glipizide affect was not mediated by catecholamine inhibition. These findings suggest a blockade of catecholamines hepatic receptors by the anticipated insulin release induced by sulfonylurea. Thus, insulin fully dominated when insulin and catecholamines were administered in a stress-like sequence. A confirmation of these findings in diabetic patients subjected to surgical stress would allow a new therapeutic application of sulfonylurea. It is concluded that an anticipated insulin release plus an insulin dominant role over catecholamines activity might explain the anti-stress effect of sulfonylurea.

The pretreatment decreased the islet ATP/ADP ratio. Whereas glucose and α-ketoisovalerate were ineffective or weakly effective, respectively, when tested separately, their combination strongly enhanced the insulin secretion. Compared with glucose, the strong amplifier α-ketoisocaproate caused less increase in NAD(P)H-fluorescence and less mitochondrial hyperpolarization. Compared with α-ketoisovalerate, α-ketoisocaproate caused greater buy glucotrol online increase in NAD(P)H-fluorescence and greater mitochondrial hyperpolarization. Neither α-ketoacid anion enhanced the islet ATP/ADP ratio during onset of the insulin secretion. α-Ketoisocaproate induced a higher pyruvate content than glucose, slowly elevated the citrate content which was not changed by glucose and generated a much higher acetoacetate content than other fuels. α-Ketoisovalerate alone or in combination with glucose did not increase the citrate content.

Cytochrome P450 (CYP) 2C9 and CYP2C19 genetic mutant could influence the plasma concentration of glipizide in human subjects, which refers to glipizide safety and adverse effects in clinic practice. A further study to investigate the relationship of the concentrations between glipizide and its metabolites in human with different CYP mutants was valuable. We firstly develop a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for simultaneous quantification of glipizide and its hydroxylated metabolites in human urine. After simple protein precipitation with methanol including 4'-OH-tolbutamide and gliclazide (both are internal standards), the analytes were chromatographed on a reversed-phased column with a mobile phase of 0.1% formic acid in acetonitrile and 0.1% formic acid in water by a gradient elution. The ion transitions of the precursor to the product ion were principally protonated ions [M+H](+) at m/z 446.4→m/z 321.1 for glipizide, m/z 462.2→m/z 321.1 for the four hydroxylated forms of glipizide, m/z 287.2→m/z 188.0 for 4'-OH-tolbutamide, and m/z buy glucotrol online 324.1→m/z 127.1 for gliclazide. The method was linear over a concentration range of 0.02-20.0ng/mL. The intraday and inter-day variances were less than 9.9%, and accuracy was within ±6.8%. The method was successfully applied to the urinary phenotyping study in volunteers after a single oral administration of 5-mg glipizide tablet, and two new hydroxycyclohexyl metabolites of glipizide (OH-gp), 4-cis-OH-gp and 3-trans-OH-gp, were found in this study.

Indapamide was extracted from human whole blood with diethyl ether and was determined by a HPLC-UV method using an Inertsil ODS-3 column and an isocratic mobile phase consisting of 55% buffer solution (2 g KH(2)PO(4), 3 ml H(3)PO(4) and 3.5 ml triethylamine in 1l of H(2)O), 40% buy glucotrol online acetonitrile and 5% methanol for 12.5 min, and then a gradient flush from 100% isocratic to a mixture of 20% isocratic mobile phase and 80% methanol for 3 min. Indapamide and glipizide (internal standard) were eluted from the column at about 10.5 and 12.8 min, respectively. The method had within day precision values in the range +/- 1.2 to +/- 9.7% (n = 5) and between day precision in the range +/- 3.3 to +/- 9.7%. The method was linear over the range of 10-400 ng/ml of indapamide in blood (R = 0.999). The LOQ (s/n = 10) of the method was 10 ng/ml. The method was applied in a study of the pharmacokinetics and bioequivalence of generic indapamide capsules (2.5 mg) in comparison with reference indapamide tablets (2.5mg), in 20 healthy male Chinese volunteers. The mean values of major pharmacokinetic parameters of C(max), AUC(0-48), AUC(0-infinity), T(max), and t(1/2) of indapamide in healthy male Chinese volunteers after po a single 5 mg dose for the test product were 331.0 +/- 39.2 ng/ml, 6,193.7+/-873.5 ng h/ml, 7311.8+/-1,232.3 ng h/ml, 3.2+/-0.9h, and 17.3+/-2.8 h, respectively. There was no significant differences between the two formulations.

Sixty-eight percent of pediatric sulfonylurea ingestions reported to poison centers do not result in laboratory or behavioral effects. Consequently, if all exposed children are admitted overnight or for 24 hours for these exposures, it will result in 600 to 700 hospital admissions per year of children who will remain free of symptoms. We prospectively studied exposures reported to buy glucotrol online 10 regional poison centers to determine if it were possible to differentiate those patients who would have symptoms from those who would remain symptom free.

Sodium was measured in beta-cell-rich pancreatic islets of mice under steady state conditions or after 6 min of exposure to 1 mM ouabain. The islet content of sodium increased when 100 microM tolbutamide or 1 microM glipizide were added to an albumin-containing (1 mg ml-1) medium, but remained unaffected at 10-fold higher concentrations. Both sulphonylurea compounds promoted the uptake of Na+ in the presence of ouabain. Whereas tolbutamide was stimulatory at 10 microM or above in a medium containing 10 mg ml-1 albumin, only 0.1 microM was required in the absence of albumin. In the latter situation there was a reduction of the stimulatory action with increase of the tolbutamide concentration from 100 to 1000 microM. The inhibitory component in the sulphonylurea action on the Na+ uptake was particularly impressive with glipizide, maximal stimulation being reached at 10 microM in the presence of 1 mg ml-1 albumin. Diazoxide (400 microM) modified the glipizide action on Na+ uptake, making 1000 microM stimulatory instead of 1 microM. The latter concentration of glipizide became inhibitory after removal of K+. Glipizide stimulated the Na+ uptake both at low and high concentrations in a medium deficient in Ca2+ or when the cotransport buy glucotrol online of Na+, K+ and Cl- was blocked by 20 microM bumetanide. The observation that the sulphonylurea-induced islet accumulation of sodium is diminished at supramaximal concentrations reinforces existing arguments for additional effects of high concentrations of hypoglycemic sulphonylureas.

The interaction of glipizide and hydroxypropyl-pcyclodextrin was investigated in the present paper. The stability constant and molar ratio of glipizide buy glucotrol online and hydroxypropyl-beta-cyclodextrin was calculated from the phase soluility diagram. The solid state inclusion complex of hydroxypropyl-beta-cyclodextrin/glipizide prepared by neutralization method was characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and powder X-ray diffraction (XRD). It was found that the phase solubility diagram of the HP-beta-CD solution showed a typical AL-type, suggesting the formation of a soluble complex of 1 : 1 molar ratio, and the stability constant was 359 L x mol(-1) at 25 degrees C. The spectra of IR, thermograph of DSC and XRD pattern of the inclusion complex were remarkably different from the glipizide and hydroxypropyl-beta-cyclodextrin/glipizide physical mixture, and indicated that hydroxypropyl-beta-cyclodextrin/glipizide inclusion complex displayed amorphous characteristic. The experiment of solubility of inclusion complex indicated that the solubility of inclusion complex increased 25-fold.

Patients suffering from this disorder mimic symptoms of diseases and seek medical procedures and operations. We present a case of a patient who underwent a thorough investigation for unexplained persistent hypoglycemia. According to the algorithm approach to the non-diabetic Cozaar 150 Mg patient, we measured insulin and c-peptide plasma levels while glucose levels were low and looked for sulphonylurea, blood and urine traces. Following the above, an endoscopic ultrasound demonstrated a small pancreatic lesion and an explorative laparotomy was performed to detect an insulinoma. This procedure was complicated by partial colectomy due to colonic gangrene. Following the patient's recovery, hypoglycemia recurred and the laboratory tests were repeated, revealing trace amounts of glipizide in her serum and urine. Studies which examined the prevalence of the phenomenon among cases of unexplained hypoglycemia, including patients who were operated for presumed insulinoma, were reviewed. No specific therapy for factitious disorder has been established. Management is based upon psychotherapy which is often not very effective. We recommend that one has to keep in mind that negative tests for sulphonylurea traces in serum and urine, do not contradict the diagnosis of factitious disorder, and it is recommended to repeat these tests several times.

Despite extensive clinical experience with second-generation oral hypoglycemic agents, the relative dosing equivalence of glyburide and glipizide remains controversial. A prospective survey was conducted to determine the feasibility and cost of converting noninsulin-dependent diabetic patients from glipizide to glyburide. A total of 211 patients previously stabilized on glipizide were converted to glyburide and returned to their respective clinics at least once during the following six months. The mean daily dose (+/- SD) of glipizide before conversion was 18.7 +/- 12.32 mg; the mean daily dose of glyburide after seven Seroquel Highest Dose months was 9.9 +/- 6.52 mg (P less than 0.001, paired t test). Glyburide was well tolerated. The conversion program appeared to be successful and resulted in a 47% reduction in the mean daily dose after conversion from glipizide to glyburide, which, in turn, conferred a 43% savings in the projected yearly expenditures for second-generation oral hypoglycemics.

1. The effects of the sulphonylureas glibenclamide, glipizide and tolbutamide on relaxant responses to the K+ channel activator, cromakalim (BRL 34915), were investigated in rabbit isolated mesenteric artery. The interaction between glibenclamide and pinacidil, another K+ channel activator, was also studied. 2. Glibenclamide produced progressive parallel shifts to the right of the cromakalim and pinacidil concentration-response curves. The calculated pA2 values were 7.16 +/- 0.03 against cromakalim and 6.66 +/- 0.05 against pinacidil. 3. Glipizide and tolbutamide also produced parallel shifts to the right of the cromakalim concentration-response curve to yield pA2 values of 5.59 and 3.98 respectively. 4. Glibenclamide had little Zyrtec Buy inhibitory effect upon vasorelaxant responses to the Ca2+ channel blocker, nifedipine. 5. The results suggest that cromakalim and pinacidil activate an ATP-sensitive K+ channel in vascular smooth muscle which may differ from that of the pancreatic beta-cells.

Activated microglia are associated with deposits of aggregated proteins within the brains of patients with Alzheimer's disease (AD), Parkinson's disease (PD) and prion diseases. Since the cytokines secreted from activated microglia are thought to contribute to the pathogenesis of these neurodegenerative diseases, compounds that suppress cytokine production have been identified as potential therapeutic targets. CD14 is a glycosylphosphatidylinositol (GPI)- anchored protein that is part of a receptor complex that mediates microglial responses to peptides that accumulate in prion disease (PrP82-146), AD (amyloid-β (Aβ)42) and PD (α-synuclein (αSN)). As some GPI-anchored proteins are released from cells by treatment with glimepiride, a sulphonylurea used for the treatment of diabetes, the effects of glimepiride upon Augmentin 457 Dosage CD14 expression and cytokine production from cultured macrophages were studied.

Pancreatic islet homogenates Viagra Generic Online display calcium-sensitive transglutaminase activity, but the role of this enzyme in the process of insulin release remains to be elucidated. Tolbutamide, gliclazide, glisoxepide, glipizide and glibenclamide inhibited transglutaminase activity in islet homogenates. When the cationic response of islet cells to hypoglycaemic sulphonylureas was suppressed by exposing intact islets to quinine, tolbutamide, gliclazide and glibenclamide caused a rapid, sustained, reversible and dose-related inhibition of insulin release. The relative efficiency of distinct hypoglycaemic sulphonylureas as inhibitor of transglutaminase activity was in mirror image of their relative potency as insulin secretagogue. However, the dose-action relationship for the inhibitory action of these agents upon insulin release from quinine-treated islets was similar in response to either tolbutamide, gliclazide or glibenclamide. These results indicate that hypoglycaemic sulphonylureas may exert an inhibitory action upon insulin release, but suggest that such an effect is not tightly related to inhibition of transglutaminase.

Pinacidil, a potassium channel opener (PCO), relaxes vascular smooth muscle by increasing potassium ion membrane conductance, thereby causing membrane hyperpolarization. PCOs also act on cardiac muscle to decrease action potential duration (APD) selectively. To examine the enantiomeric selectivity of pinacidil, the stereoisomers of pinacidil (a 4-pyridylcyanoguanidine) and its 3-pyridyl isomer (LY222675) were synthesized and studied in canine Purkinje fibers and cephalic veins. The (-)-enantiomers of both pinacidil and LY222675 were more potent in relaxing phenylephrine-contracted cephalic veins and decreasing APD than were their corresponding (+)-enantiomers. The EC50 values for (-)-pinacidil and (-)-LY222675 in relaxing cephalic veins were 0.44 and 0.09 microM, respectively. In decreasing APD, the EC50 values were 3.2 microM for (-)-pinacidil and 0.43 microM for (-)-LY222675. The eudismic ratio was greater for the 3-pyridyl isomer than for pinacidil in both cardiac (71 vs. 22) and vascular (53 vs. 17) tissues. (-)-LY222675 and (-)-pinacidil (0.1-30 microM) also increased 86Rb efflux from cephalic veins to a greater extent than did their respective optical antipodes. The antidiabetic sulfonylurea, glyburide (1-30 microM), shifted the vascular concentration-response curve of (-)-pinacidil to the right by a similar extent at each inhibitor concentration. Glipizide also antagonized the response to (-)-pinacidil, but was about 1/10 as potent with a maximal shift occurring at 10 and 30 microM. Glyburide antagonized the vascular relaxant effects of 0.3 microM (-)-LY222675 (EC50, 2.3 microM) and reversed the decrease in APD caused by 3 microM (-)-LY222675 (EC50, 1.9 microM). Nitroprusside did not alter 86Rb efflux, and vascular relaxation induced by sodium nitroprusside was unaffected by sulfonylureas. Thus, the enantiomers of the 3-pyridyl isomer of pinacidil demonstrate enhanced stereospecificity in both canine cardiac and vascular tissues compared to the enantiomers of pinacidil. However, the relative selectivity of pinacidil and its 3-pyridyl isomer for cardiac and vascular smooth muscle remains unaltered. Sulfonylureas antagonize the more potent enantiomers in both tissues, supporting the involvement of an ATP-sensitive potassium channel in the action of PCOs; however, antagonism in canine vascular smooth muscle by sulfonylureas does not resemble classical competitive antagonism.

The effect of combined insulin-glibenclamide therapy on glucose control was evaluated in a double-blind placebo controlled study of 20 patients with non-insulin-dependent diabetes mellitus (NIDDM) and second failure to oral antidiabetic therapy with glibenclamide or glipizide. After an observation period of 1-3 months, insulin treatment was initiated which resulted in rapid improvement of the glycemic control within 6 weeks. Thereafter glibenclamide or placebo was added to insulin for a further 12 weeks. Glibenclamide improved the glycemic control as expressed by a diminution of blood glucose and HbA1c. This was observed in spite of the fact that the daily insulin dose was reduced by approximately 30% in the glibenclamide-treated group of patients. It is concluded that in NIDDM patients with second failure to glibenclamide ot glipizide therapy, the responsiveness to glibenclamide may be at least partially restored by a short period of insulin treatment. It is suggested that therapy with insulin and glibenclamide is an appropriate treatment regimen for NIDDM patients with second failure to sulfonylurea therapy.

Previous reports have suggested the involvement of voltage-activated calcium (Ca2+) channels in bone metabolism and in particular on the secretion of osteocalcin by osteoblast-like cells. We now report that potassium (K+) channels can also modulate the secretion of osteocalcin by MG-63 cells, a human osteosarcoma cell line. When 1,25-dihydroxyvitamin D3(1,25(OH)2D3)-treated MG-63 cells were depolarized by step increases of the extracellular K+ concentration ([K+]out) from 5-30 mM, osteocalcin (OC) secretion increased from a control value of 218 +/- 13 to 369 +/- 18 ng/mg of protein/48 h (p < 0.005 by analysis of variance). In contrast, in the absence of 1,25(OH)2D3, there is no osteocalcin secretion nor any effect of cell depolarization on this activity. The depolarization-induced increase in 1,25(OH)2D3-dependent osteocalcin secretion was totally inhibited in the presence of 10 microM Nitrendipine (a Ca2+ channel blocker, p < 0.005) without affecting cellular alkaline phosphatase nor cell growth. Charybdotoxin, a selective blocker of Ca2+-dependent K+ channels (maxi-K) present in MG-63 cells, stimulated 1,25(OH)2D3-induced osteocalcin synthesis about 2-fold (p < 0.005) after either 30, 60, or 120 minutes of treatment. However, Charybdotoxin was without effect on basal release of osteocalcin in the absence of 1,25(OH)2D3 pretreatment. Using patch clamp technique, we occasionally observed the presence of a small conductance K+ channel, compatible with an ATP-dependent K+ channel (GK[ATP]) in nonstimulated cells, whereas multiple channel openings were observed when cells were treated with Diazoxide, a sulfonamide derivative which opens GK(ATP). Western blot analysis revealed the presence of the N-terminal peptide of GK(ATP) in MG-63 cells, and its expression was regulated with the proliferation rate of these cells, maximal detection by Western blots being observed during the logarithmic phase of the cycle. Glipizide and Glybenclamide, selective sulfonylureas which can block GK(ATP), dose-dependently enhanced 1,25(OH)2D3-induced OC secretion (p < 0.005). Reducing the extracellular calcium concentration with EGTA (microM range) totally inhibited the effect of Glipizide and Glybenclamide on osteocalcin secretion (p < 0.005), which remained at the same levels as controls. Diazoxide totally prevented the effect of these sulfonylureas. These results suggest that voltage-activated Ca2+ channels triggered via cell depolarization can enhance 1,25(OH)2D3-induced OC release by MG-63 cells. In addition, OC secretion is increased by blocking two types of K+ channels: maxi-K channels, which normally hyperpolarize cells and close Ca2+ channels, and GK(ATP) channels. The role of these channels is closely linked to the extracellular Ca2+ concentration.

Over 10 years, haemoglobin A1c (HbA1c) was 7.0% (6.2-8.2) in the intensive group compared with 7.9% (6.9-8.8) in the conventional group--an 11% reduction. There was no difference in HbA1c among agents in the intensive group. Compared with the conventional group, the risk in the intensive group was 12% lower (95% CI 1-21, p=0.029) for any diabetes-related endpoint; 10% lower (-11 to 27, p=0.34) for any diabetes-related death; and 6% lower (-10 to 20, p=0.44) for all-cause mortality. Most of the risk reduction in the any diabetes-related aggregate endpoint was due to a 25% risk reduction (7-40, p=0.0099) in microvascular endpoints, including the need for retinal photocoagulation. There was no difference for any of the three aggregate endpoints between the three intensive agents (chlorpropamide, glibenclamide, or insulin). Patients in the intensive group had more hypoglycaemic episodes than those in the conventional group on both types of analysis (both p<0.0001). The rates of major hypoglycaemic episodes per year were 0.7% with conventional treatment, 1.0% with chlorpropamide, 1.4% with glibenclamide, and 1.8% with insulin. Weight gain was significantly higher in the intensive group (mean 2.9 kg) than in the conventional group (p<0.001), and patients assigned insulin had a greater gain in weight (4.0 kg) than those assigned chlorpropamide (2.6 kg) or glibenclamide (1.7 kg).

A sensitive and selective high-performance liquid chromatographic method for determination of intact glipizide in human plasma or urine has been developed. The plasma and urine samples were acid-buffered, before tolbutamide was added as internal standard. The samples were extracted with benzene, and the organic layer was evaporated to dryness. The residue was dissolved in equilibrated mobile phase (acetonitrile-0.01 M phosphate buffer pH 3.5, 35:65), and an aliquot of 20 microliters was chromatographed on a Spherisorb ODS reversed-phase column. Quantitation was achieved by monitoring the ultraviolet absorbance at 275 nm. The response was linear (0-1000 ng/ml) and the detection limit was 5-10 ng/ml in plasma or urine. The within-assay variation was less than or equal to 10%. No interferences from metabolites or endogenous constituents were observed. The utility of the assay was demonstrated by determining glipizide in samples from a diabetic subject receiving a therapeutic dose of 5 mg of the drug.

In hepatocytes isolated from fed rats, both tolbutamide and glipizide caused a dose-dependent activation of glycogen phosphorylase, possibly by a Ca2+-mediated mechanism. Maximal effects (about twofold) were already obtained when drugs were used at 0.5 mmol/L, the calculated concentrations of tolbutamide and glipizide responsible for the half-maximal effects being 60 and 30 mumol/L, respectively. The activation of glycogen phosphorylase caused the mobilization of glycogen and increased the cellular concentration of hexose 6-phosphates (glucose 6-phosphate plus fructose 6-phosphate) and that of fructose 2,6-bisphosphate. Under the influence of sulfonylureas, glucose formation was slightly stimulated while the rate of L-lactate production was more markedly incremented, indicating that sulfonylureas canalize the metabolic flux coming from glycogen mainly to the glycolytic pathway. These results suggest that a glycogenolytic action of sulfonylureas could collaborate to raise hepatic fructose 2,6-bisphosphate concentration in the fed animal.
