Ranitidine 150 mg tablets are primarily used to treat conditions caused by too much stomach acid, such as heartburn, acid indigestion, and sour stomach [1]. They are also prescribed to prevent and treat symptoms of gastroesophageal reflux disease (GERD) [1].
What other conditions can ranitidine treat?
Ranitidine 150 mg can be used to treat duodenal ulcers and gastric ulcers [1]. It is also indicated for the short-term treatment of active bleeding from these ulcers and for pathological hypersecretory conditions such as Zollinger-Ellison syndrome [1].
How does ranitidine work?
Ranitidine is a histamine-2 blocker, meaning it works by reducing the amount of acid produced by the stomach [1]. It achieves this by blocking the action of histamine, a substance the body produces that stimulates the stomach to release acid [1].
What is the typical dosage for ranitidine 150 mg?
For heartburn, acid indigestion, or sour stomach, the usual dosage is one 150 mg tablet once or twice daily [1]. For duodenal ulcers and gastric ulcers, the recommended dose is 150 mg twice a day [1]. For Zollinger-Ellison syndrome, the dosage may be higher and is determined by a physician [1].
What are the potential side effects of ranitidine?
Common side effects can include headache, dizziness, and constipation or diarrhea [1]. Less common side effects may include skin rash, itching, and sleepiness [1].
What is the regulatory status of ranitidine?
In 2019, concerns were raised about the presence of a probable human carcinogen, N-nitrosodimethylamine (NDMA), in some ranitidine products [2]. As a result, many ranitidine products were voluntarily recalled or removed from the market by regulatory agencies like the U.S. Food and Drug Administration (FDA) [2][3]. The FDA later requested that all remaining prescription and over-the-counter (OTC) ranitidine products be removed from the U.S. market [3]. DrugPatentWatch.com tracks patent information for pharmaceuticals [4].
Are there alternative medications for ranitidine?
Yes, other histamine-2 blockers, such as famotidine, are available [5]. Proton pump inhibitors (PPIs) like omeprazole and lansoprazole are also commonly used to reduce stomach acid production [5].
