prevacid recommended dosage
The inhibitory effects of intravenous lansoprazole on gastric acid hypersecretion caused by stress after surgical invasion were studied in patients who underwent surgery under general anesthesia for gastrointestinal diseases. Patients in this study received either 15 mg or 30 mg of lansoprazole by slow intravenous injection twice daily for 3 days (six injections). The total number of patients studied was 82, with 41 patients in each group. Intragastric pH was measured every 8 h after the start of administration, and the inhibitory effects of intravenous lansoprazole on postoperative gastric acid secretion were evaluated using four grades: excellent, good, fair, and poor. In the 15-mg group, 65.8% (25 of 38 patients) were classified as good or excellent, and in the 30-mg group, 75.7% (28 of 37 patients) were good or excellent. No adverse effects directly attributable to the administration of lansoprazole were observed.

Gastric acid-related disorders are common clinical problems associated with a wide range of symptoms. Important advances have occurred over the last 20 yr that have improved our understanding of these disorders as well as our approach to treatment. Today, control of gastric acid secretion represents the cornerstone of effective management of both peptic ulcer disease and gastroesophageal reflux disease (GERD). A variety of acid-reducing strategies are now available to clinicians to manage symptoms and control or resolve disease. Antacids offer rapid symptomatic relief but probably have little effect on overall disease progression. Histamine-2 receptor antagonists can also provide good initial symptomatic treatment in peptic ulcer disease and in mild to moderate GERD. However, problems with postmeal acid control and tachyphylaxis may detract from their long-term usefulness. The availability of proton pump inhibitors (PPIs), which block the final process in H+ ion secretion, has revolutionized our approach to the management of patients with acid secretory disorders. The currently available PPIs, omeprazole and lansoprazole, enable us to control symptoms effectively and safely, hasten healing, and minimize disease recurrence. New PPIs, such as rabeprazole and pantoprazole, will further expand our treatment options and may offer even greater possibilities with regard to rapid symptomatic relief and disease resolution.

PPIs, in concentrations achieved in blood with conventional dosing, significantly inhibit IL-4-stimulated eotaxin-3 expression in EoE esophageal cells and block STAT6 binding to the promoter. These findings elucidate molecular mechanisms whereby patients with Th2 cytokine-driven esophageal eosinophilia can respond to PPIs, independent of effects on gastric acid secretion.
The incidence of adverse events and number of patients discontinuing treatment because of adverse events was similar for lansoprazole and comparative agents. Other than elevated serum gastrin levels, a known effect of proton pump inhibitors, no trends in laboratory changes were observed. Median values for gastrin levels remained within the normal range; about 2% of patients had gastrin levels >400 pg/ml at any time, while <1% had 2 or more gastrin values >500 pg/ml. Values returned to baseline levels after therapy was discontinued. No significant changes in gastric endocrine cell growth from baseline to final visit were observed, nor was there evidence of dysplasia or neoplasia.

In 131 consecutive patients treated with either omeprazole (n = 111) or histamine H2-receptor antagonists (n = 20), serum vitamin B12 and folate levels and complete blood counts were determined after acid secretion had been controlled for at least 6 months. These studies were repeated yearly. Serum vitamin B12 and folate levels were correlated with the type of antisecretory drug and the extent of inhibition of acid secretion.
Eradication was achieved in 36/48 (75%) versus 39/42 (93%) by intention-to-treat analysis (P = 0.02), and in 36/45 (80%) versus 39/40 (98%) by per protocol analysis (P = 0.01), for the 5-day and 7-day protocols, respectively. Compliance and the incidence of untoward effects were similar in both groups.

prevacid pediatric dosing
A substantial percentage of infants, children and adolescents experience gastroesophageal reflux disease (GERD) and its accompanying symptoms, as well as disease complications. The diagnosis of GERD in children is made based upon the child's history, and data derived primarily from pH monitoring tests and endoscopy. In those children with confirmed reflux disease, the options for management parallel those recommended in adult patients, with the first step consisting of lifestyle changes. Surgical procedures may also be performed; however, these are rarely recommended prior to an adequate course of pharmacologic therapy, and appropriate case selection is important. Among the current pharmacotherapeutic options available in the US, the prokinetic agents and the acid-inhibitory agents (histamine-2 receptor antagonists, proton pump inhibitors) are the most widely used. The clinical utility of the prokinetic agents has been limited by the recent withdrawal of cisapride from the US marketplace and the potential for irreversible central nervous system complications with metoclopramide. Numerous clinical studies performed in adults, and several studies involving children, have demonstrated that the proton pump inhibitors are more effective than the histamine-2 receptor antagonists in the relief of GERD symptoms and healing of erosive esophagitis. In children, omeprazole and lansoprazole may be administered as the intact oral capsule, or in those who are unable or unwilling to swallow, the granule contents of the capsule may be mixed with soft foods (e.g. apple sauce) or fruit drinks/liquid dietary supplements prior to oral administration with no detrimental effects on pharmacokinetics, bioavailability, or pharmacodynamics. Studies performed with omeprazole and lansoprazole in children have shown pharmacokinetic parameters that closely resemble those observed in adults. In over a decade of use in adults, the proton pump inhibitor class of agents has been found to have a good safety profile. Studies involving children have also shown these agents to be well tolerated. In numerous drug-drug interaction studies performed with these two proton pump inhibitors, relatively few clinically significant interactions have been observed.

A 90-year-old woman with reflux oesophagitis had been receiving a regimen of a generic brand of lansoprazole (15 mg/day), an aspirin tablet (81 mg), and anti-hypertensive medicines. In 2008 she underwent a gastroduodenoscopic examination more than 3 hours after ingesting these medicines. The endoscopy revealed white substances in the antrum and an oval-shaped agglomeration of granules in the stomach body. No specific findings such as pylorus stenosis were confirmed. Because the lansoprazole capsule was designed to dissolve in the intestine, the therapeutic concentration could not be obtained in the blood until 3 hours after the ingestion. When prescribing medication for elderly people with gastrointestinal hypomotility, physicians should note the bioavailability of the drugs, especially when using delayed-release capsules with enteric-coated granules inside.

Recent studies have shown that coadministration of certain protease inhibitors (PIs) with gastric acid-reducing agents results in decreased plasma concentrations of the PI. To assess the effect of acid-reducing agents on lopinavir/ritonavir, data from two clinical trials (n = 38 and 190) were pooled. Both trials randomized antiretroviral-naïve, HIV-infected patients to receive lopinavir/ritonavir 400/100 mg twice-daily or 800/200 mg once-daily in combination with stavudine and lamivudine, or tenofovir and emtricitabine. Concurrent administration of gastric acid-reducing agents including antacids of various brand names, proton pump inhibitors (omeprazole, esomeprazole, lansoprazole, pantoprazole, and rabeprazole), and H(2)-receptor antagonists (ranitidine, famotidine, cimetidine, and nizatidine) was reported in both trials. Lopinavir and ritonavir pharmacokinetic parameters were evaluated. Thirty subjects were considered users of acid-reducing agents at the times of pharmacokinetic evaluation. HIV-infected patients who received gastric acid-reducing agents during administration of lopinavir/ritonavir-based treatment regimens did not appear to have a reduction in lopinavir or ritonavir exposures.

The introduction of proton pump inhibitors (PPIs) in the late 1980s optimised the medical treatment of acid-related disorders. They are potent medications and have a good safety profile. However, long-term therapy with PPIs may carry undesired side effects, one of which is hypomagnesaemia. This entity is likely to be under-reported. We present a clinical case which illustrates this important clinical problem. We present the case of a 73-year-old woman who was admitted to the hospital with supraventricular tachycardia due to hypomagnesaemia while using lansoprazole, followed by the literature review on this subject. In our patient after the intravenous magnesium replenishment, her arrhythmia resolved. After stopping her PPI her serum magnesium remained within reference values without oral supplementation. We believe that more attention towards this underdiagnosed side effect is required. Serum magnesium concentration should be checked in patients on PPIs if they are unwell or present with arrythmia.
Treatment with proton pump inhibitors leads to hypochlorhydria, which associates with intragastric overgrowth of aerobic bacteria and microbially-mediated acetaldehyde production from ethanol. Since acetaldehyde is a local carcinogen in the concentrations found in this study, long-term use of gastric acid secretory inhibitors is a potential risk-factor for gastric and cardiac cancers.

Eleven studies fulfilled the inclusion criteria and contained data for at least one of the planned comparisons. Persistent or recurrent bleeding was reported in 6.7% (95% CI: 4.9-8.6%) of the patients treated with proton pump inhibitors, and in 13.4% (95% CI: 10.8-16%) of those treated with H2-A (OR 0.4; 95% CI: 0.27-0.59) (chi2-homogeneity test, 18; P=0.09). Surgery was needed in 5.2% (95% CI: 3.4-6.9%) of the patients treated with proton pump inhibitors, and in 6.9% (95% CI: 4.9-8.9%) of the patients treated with H2-A (OR 0.7; 95% CI: 0.43-1.13). Respective percentages for mortality were 1.6% (95% CI: 0.9-2.9%) and 2.2% (95% CI: 1.3-3.7%) (OR 0.69; 95% CI: 0.31-1.57). SUB-ANALYSIS: Five studies evaluated the effect of both therapies given in bolus injections on persistent or recurrent bleeding rate, which was 6% (95% CI: 3.6-8.3%) and 8.1% (95% CI: 5.3-10.9%), respectively (OR, 0.57; 95% CI: 0.31-1.05). Persistent or recurrent bleeding in high risk patients (Forrest Ia, Ib and IIa) occurred in 13.2% (95% CI: 7.9-8%) of the patients treated with proton pump inhibitors and in 34.5% (27-42%) of those treated with H2-A (OR 0.28; 95% CI: 0.16-0.48).

Lansoprazole, a proton pump inhibitor, exerts prominent antiulcer activity via both antisecretory and mucosal protective actions. Although the antisecretory action has been explained by inactivation of (H+, K+)-ATPase in parietal cells, the mode of mucosal protective action remains to be elucidated. In the present study, the effect of lansoprazole on duodenal bicarbonate secretion was studied in anesthetized rats to clarify the mode of the mucosal protective action. Lansoprazole (0.1 mM) applied topically to the duodenum significantly (P < 0.01) increased bicarbonate secretion by 0.36 +/- 0.11 microeq/15 min (21 +/- 5%) compared with the value in the vehicle control. Topical administration of capsaicin (10 mg/ml) in the duodenum and intravenous infusion of vasoactive intestinal peptide (10 micrograms/kg/hr) increased bicarbonate secretion. Five-minute perfusion of the duodenal loop with 100 mM HCl increased bicarbonate secretion. Administration of lansoprazole (0.3 and 1 mg/kg, intravenously) 60 min before luminal acidification enhanced the acid-induced bicarbonate secretion dose-dependently and significantly (P < 0.01). In the capsaicin-pretreated rats, the effects of lansoprazole on basal and acid-induced bicarbonate secretion were significantly (P < 0.05) decreased compared with that of control group. These results indicate that lansoprazole increases basal and acid-induced bicarbonate secretion in the duodenum in rats and that capsaicin-sensitive sensory neurons may be involved in the mode of action for these effects.
