Gasorab

Gasorab Uses, Dosage, Side Effects, Food Interaction and all others data.

Gasorab Sodium is an antiulcerant drug in the class of Proton Pump Inhibitors. Gasorab Sodium is a substituted benzimidazole which suppresses gastric acid secretion by inhibiting the gastric H+/K+-ATPase enzyme at the secretory surface of the gastric parietal cell. It is an enteric coated tablet, because of its coated formulation it is highly stable in stomach and because of higher pKa value of Gasorab Sodium it provides faster onset of action. It blocks the final step of gastric acid secretion.

After oral administration of 20 mg, Gasorab is absorbed and can be detected in plasma by 1 hour. The effects of food on the absorption of Gasorab have not been evaluated. Gasorab is 96.3% bound to human plasma proteins. Gasorab is primarily metabolized in the liver by Cytochrome P-450 3A (Sulphone metabolite) and 2C19 (Desmethyl Gasorab). Following a single 20 mg oral dose of Gasorab, approximately 90% of the drug is eliminated in the urine.The remainder of the dose is excreted in the feaces.

Gasorab prevents the production of acid in the stomach. It reduces symptoms and prevents injury to the esophagus or stomach in patients with gastroesophageal reflux disease (GERD) or ulcers. Gasorab is also useful in conditions that produce too much stomach acid such as Zollinger-Ellison syndrome. Gasorab may also be used with antibiotics to get rid of bacteria that are associated with some ulcers. Gasorab is a selective and irreversible proton pump inhibitor, suppresses gastric acid secretion by specific inhibition of the H+, K+ -ATPase, which is found at the secretory surface of parietal cells. In doing so, it inhibits the final transport of hydrogen ions (via exchange with potassium ions) into the gastric lumen.

Uses

Short-term treatment in healing and symptomatic relief of duodenal ulcers and erosive or ulcerative Gastroesophageal Reflux Disease (GERD).

Maintaining healing and reducing relapse rates of heartburn symptoms in patients with GERD.

Treatment of daytime and night time heartburn and other symptoms associated with GERD.

Long-term treatment of pathological hypersecretory conditions, including Zollinger Ellison Syndrome.

In combination with Amoxicillin and Clarithromycin to eradicate Helicobacter pylori.

Gasorab is also used to associated treatment for these conditions: Duodenal Ulcer, Gastric Ulcer, Gastro-esophageal Reflux Disease (GERD), Heartburn, Helicobacter Pylori Infection, NSAID Associated Gastric Ulcers, Non-erosive Reflux Esophagitis Disease (NERD), Vomiting, Zollinger-Ellison Syndrome, Erosive reflux esophagitis

How Gasorab works

Gasorab belongs to a class of antisecretory compounds (substituted benzimidazole proton-pump inhibitors) that do not exhibit anticholinergic or histamine H2-receptor antagonist properties, but suppress gastric acid secretion by inhibiting the gastric H+/K+ATPase (hydrogen-potassium adenosine triphosphatase) at the secretory surface of the gastric parietal cell. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, rabeprazole has been characterized as a gastric proton-pump inhibitor. Gasorab blocks the final step of gastric acid secretion. In gastric parietal cells, rabeprazole is protonated, accumulates, and is transformed to an active sulfenamide. When studied in vitro, rabeprazole is chemically activated at pH 1.2 with a half-life of 78 seconds.

Dosage

Gasorab dosage

Healing of Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD): 20 mg to be taken once daily for 4 to 8 weeks. For those patients who have not healed after 8 weeks of treatment, an additional 8 week course may be considered.

Maintenance of Healing of Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD Maintenance): The recommended adult oral dose is 20 mg once daily.

Treatment of Symptomatic Gastroesophageal Reflux Disease (GERD):The recommended adult oral dose is 20 mg once daily for 4 weeks. If symptoms do not resolve completely after 4 weeks, an additional course of treatment may be considered.

Healing of Duodenal Ulcers:The recommended adult oral dose is 20 mg once daily after the morning meal for a period up to four weeks. Most patients with duodenal ulcer heal within four weeks. A few patients may require additional therapy to achieve healing.

Helicobacter pylori Eradication: To Reduce the Risk of Duodenal Ulcer Recurrence-

  • Gasorab Sodium 20 mg Twice Daily for 7 Days
  • Amoxicillin 1000 mg Twice Daily for 7 Days
  • Clarithromycin 500 mg Twice Daily for 7 Days

All three medications should be taken twice daily with the morning and evening meals. It is important that patients comply with the full 7-day regimen.

Treatment of Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome: The dosage of Gasorab Sodium in patients with pathologic hypersecretory conditions varies with the individual patient. The recommended adult oral starting dose is 60 mg once a day. Doses should be adjusted to individual patient needs and should continue for as long as clinically indicated. Some patients may require divided doses. Doses up to 100 mg QD and 60 mg BID have been administered. Some patients with Zollinger-Ellision syndrome have been treated continuously with Gasorab Sodium for up to one year.

Side Effects

Gasorab Sodium may sometimes cause headache, diarrhoea, abdominal pain, vomiting, constipation, dry mouth, increased or decreased appetite, muscle pain, drowsiness and dizziness.

Precaution

Administration of Gasorab Sodium to patients with mild to moderate liver impairment resulted in increased exposure and decreased elimination. Caution should be exercised in patients with severe hepatic impairment.

Interaction

Gasorab is metabolized by the Cytochrome P-450 (CYP-450) drug metabolizing enzyme system. Gasorab does not have clinically significant interactions with other drugs metabolized by the CYP-450 system,such as Warfarin and Theophylline given as single oral dose, Diazepam as a single intravenous dose, and Phenytoin given as a single intravenous dose. In normal subjects, co-administration of Gasorab 20 mg QD resulted in an approximately 30% decrease in the bioavailability of Ketoconazole and increase in the AUC and Cmax for digoxin of 90% and 29% respectively.

Food Interaction

  • Take with or without food. Food delays drug absorption, but not to a clinically significant extent.

Elimination Route

Absolute bioavailability is approximately 52%.

Half Life

1-2 hours (in plasma)

Elimination Route

Following a single 20 mg oral dose of 14C-labeled rabeprazole, approximately 90% of the drug was eliminated in the urine, primarily as thioether carboxylic acid; its glucuronide, and mercapturic acid metabolites.
