Omsynth Lifesciences Pvt. Ltd. is one of the leading manufacturer and exporter of Cimetidine. Cimetidine is a histamine H2-receptor antagonist widely used to reduce gastric acid secretion in the treatment of peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. It works by competitively blocking H2 receptors on the parietal cells of the stomach, thereby inhibiting acid production and promoting ulcer healing. The drug is administered orally or intravenously and is rapidly absorbed, with a bioavailability of around 60–70%. Cimetidine may also have mild antiandrogenic effects, which can occasionally cause gynecomastia or impotence in long-term use. Common side effects include headache, dizziness, diarrhea, and fatigue, while serious adverse effects are rare. It can interact with other drugs by inhibiting cytochrome P450 enzymes, affecting the metabolism of certain medications. Cimetidine has been largely replaced by newer H2 blockers and proton pump inhibitors but remains a historically important therapy for acid-related disorders.
