103577-45-3 Usage

Adverse reactions

This product can cause constipation, diarrhea, dry mouth, abdominal distention, anemia, increased white blood cells and eosinophils, thrombocytopenia, elevated liver enzymes, headache, drowsiness, insomnia, skin rashes, itching, etc., and occasionally cause fever, increased total cholesterol and uric acid value, etc.

Uses

For the treatment of acid-reflux disorders (GERD), peptic ulcer disease, H. pylori eradication, and prevention of gastroinetestinal bleeds with NSAID use.

Uses

A H+,K+-ATPase inhibitor that displays antisecretory activity

Brief Introduction

Lansoprazole is in a class of drugs called proton pump inhibitors (PPI) which prevent the stomach from producing gastric acid.The other drugs in PPI family include:
  • rabeprazole (Aciphex),
  • omeprazole (Prilosec),
  • pantoprazole (Protonix),
  • esomeprazole (Nexium).
Proton pump inhibitors are used for the treatment of conditions such as ulcers, gastroesophageal reflux disease (GERD) and Zollinger-Ellison syndrome that are caused by stomach acid. Lansoprazole, like other proton-pump inhibitors, blocks the enzyme in the
wall of the stomach that produces acid. By blocking the enzyme, the production of acid is decreased, and this allows the stomach and esophagus to heal.

Uses

Lansoprazole is a proton pump inhibitor (PPI) similar to omeprazole that inactivates the hydrogen/potassium-stimulated ATPase pumps in parietal cells, thus inhibiting gastric acid secretion and increasing intragastric pH. It is a potent inhibitor of gastric acidity which is widely used in the therapy of gastroesophageal reflux and peptic ulcer disease. Lansoprazole is a racemic mixture of (R)- and (S)-isomers. Dexlansoprazole is an isomer of lansoprazole that has a similar spectrum of activity and toxicities. Lansoprazole therapy is associated with a low rate of transient and asymptomatic serum aminotransferase elevations and is a reported, but very rare cause of clinically apparent liver injury.
Lansoprazole's plasma elimination half-life is not proportional to the duration of the drug's effects (i. e. gastric acid suppression). The plasma elimination half-life is 1. 5 hours or less, and the effects of the drug last for over 24 hours after it has been given for 5 days or more.
Lansoprazole is a prescription medicine used to treat:
  1. gastroesophageal reflux disease (GERD)
  2. erosive esophagitis
  3. stomach ulcers
  4. duodenal ulcers
  5. H. Pylori infections
  6. Zollinger-Ellison syndrome

Chemical Properties

White Crystalline Powder

Gastric acid secretion inhibitor

R-(+)-Lansoprazole is the dextroisomer of lansoprazole and a kind of anti-ulcer drug. It is the substitution product of benzimidazole derivative byimporting the fluorine element in the molecular structure and the is the second proton pump inhibitor after omeprazole.  R-(+)-Lansoprazole has a better inhibitory effect for gastric acid secretion than that of other drugs (omeprazole, pantoprazole, rabeprazole) and it can significantly inhibit ulcer. It has a better Curative effect for ethanol-induced gastric mucosa lesion and acid hypersecretion induced duodenal ulcer than that of famotidine and omeprazole. In addition, This product also has an anti-Helicobacter pylori effect similar to that of Bismuth preparations and can be used to treat reflux esophagitis and Zollinger-Ellison syndrome.
pharmacodynamics   
R-(+)-Lansoprazole can transform into active sulfonamide derivatives. In the tubule acidic environment of parietal cells, which are connected to the sulfydryl of H+-K+-(ATP)adenosine triphosphatase(the last step of the enzyme catalyzed gastric acid secretion process),passivat H+-K+-ATP enzyme and Inhibit the gastric acid secretion regulated by central and peripheral nervous systems. The inhibition effect of gastric acid secretion of this product is at least as strong as omeprazole. In vivo studies of animal model have demonstrated that the inhibition effect for gastric acid secretion of R-(+)-Lansoprazole is inferior to H2 receptor antagonist ranitidine and famotidine, but just as effective as omeprazole. Unlike the H2 receptor antagonist, whether taken in the morning or evening, this product can inhibit gastric acid secretion during the day and night. It can also reduce the gastric acid secretion, inhibit the secretion of pepsin and its activity and clear pyloric campylobacter on gastric mucosa (A bacterium of causing recurrence. of peptic ulcer).
It can also be used to treat Helicobacter pylori infection, alongside antibiotics as adjunctive treatment, to kill H. pylori causing ulcers or other problems involves using two other drugs known as "triple therapy", and involves taking twice daily for 10 or 14 days lansoprazole, amoxicillin, and clarithromycin.

Pharmacokinetics

When this product transform into active AG-1812 and AG-2000, R-(+)-Lansoprazole in serum is metabolized quickly and completely into two main faeces: Lansoprazole sulfone and hydroxy orchid sola. About 14%~23% of doses are excreted in the urine as conjugated and non-conjugated hydroxylation metabolites and no prototype of this product is found. The half-life of this product is 1.3~1.7 h, about 2 h for elderly people and as long as 7 h for patients with severe liver failure. The Peak blood concentration can reach 1038μg/L within 2 h after taking 30 mg enteric capsules of this product.

Marketing internationally

The lansoprazole molecule is off-patent and so generic drugs are available under many brand names in many countries;there are patents covering some formulations in effect as of 2015.
Since 2009, lansoprazole has been sold over the counter (OTC) in the U.S. in a marketed by Novartis as Prevacid 24HR. In Australia, it is being marketed by Pfizer as Zoton.

Uses
