Ranitidine tablets IP 150mg are used to treat and prevent ulcers in the stomach and intestines. They are also prescribed for conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome. Additionally, ranitidine can be used to treat gastroesophageal reflux disease (GERD), a condition that causes heartburn and acid regurgitation. [1][2]
How does ranitidine work to reduce stomach acid?
Ranitidine is a histamine-2 blocker. It works by blocking the action of histamine on parietal cells in the stomach lining. Histamine stimulates these cells to produce acid. By blocking histamine, ranitidine effectively reduces the amount of acid secreted by the stomach. [3]
What are the common side effects of ranitidine?
Common side effects of ranitidine can include headache, dizziness, constipation, and diarrhea. Less common side effects may involve rash or fatigue. [1][2]
Are there any safety concerns or recalls related to ranitidine?
In 2019, concerns arose regarding the presence of N-nitrosodimethylamine (NDMA), a probable human carcinogen, in some ranitidine products. This led to voluntary recalls and market withdrawals by various manufacturers and regulatory agencies. [4][5]
What alternatives are available for treating acid-related stomach issues?
Other medications used to treat acid-related stomach issues include proton pump inhibitors (PPIs) such as omeprazole and lansoprazole, as well as other H2 blockers like famotidine and cimetidine. Antacids can also provide short-term relief from heartburn. [3][6]
When does the patent for ranitidine expire?
Ranitidine has been available for many years, and its primary patents have long expired. This has allowed for the availability of generic versions. DrugPatentWatch.com tracks patent expiries for numerous drugs, and ranitidine is not subject to active patent protection that would restrict generic entry. [7]
Who makes ranitidine tablets IP 150mg?
Following the expiration of original patents and subsequent recalls due to NDMA concerns, various pharmaceutical companies produce ranitidine. Specific manufacturers for ranitidine tablets IP 150mg can vary by region and availability.
What is the difference between ranitidine and omeprazole?
Ranitidine is a histamine-2 blocker that reduces acid production. Omeprazole is a proton pump inhibitor (PPI), which is a more potent class of acid-reducing medication. PPIs work by directly blocking the proton pumps in parietal cells, leading to a more significant and sustained reduction in stomach acid compared to H2 blockers. [3][6]
