Ranitidine hydrochloride tablets are used to treat and prevent the recurrence of ulcers in the stomach and intestines. They are also prescribed to manage gastroesophageal reflux disease (GERD), a condition where stomach acid flows back into the esophagus, causing heartburn and other symptoms. Additionally, ranitidine hydrochloride tablets can be used to treat conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome [1].
How does ranitidine work?
Ranitidine is a histamine-2 (H2) blocker. It works by decreasing the amount of acid produced by the stomach. By reducing stomach acid, it helps to heal ulcers and relieve symptoms associated with excess acid production [1].
What are the common side effects of ranitidine?
Common side effects of ranitidine hydrochloride tablets can include headache, dizziness, constipation, diarrhea, nausea, and abdominal pain [1].
Why was ranitidine recalled?
Ranitidine products were recalled from the market due to concerns about a contaminant called N-nitrosodimethylamine (NDMA) [2]. NDMA is classified as a probable human carcinogen. Some ranitidine products were found to contain unacceptable levels of NDMA, which could increase the risk of cancer over time with continued exposure [2][3].
What are the alternatives to ranitidine?
Following the recall of ranitidine, healthcare providers often recommend alternative medications to manage conditions previously treated with ranitidine. These alternatives include other H2 blockers like famotidine and cimetidine, as well as proton pump inhibitors (PPIs) such as omeprazole, esomeprazole, and lansoprazole [4]. Lifestyle modifications may also be recommended as part of treatment [1].
When does patent expiry for ranitidine matter?
The patent expiry for ranitidine was a significant factor in the availability of generic versions of the drug, which would typically lower its cost. However, the market withdrawal due to NDMA contamination superseded patent expiry considerations for most ranitidine products [5].
