Ranitidine 150 mg is a medication used to decrease the amount of acid the stomach produces [1]. It belongs to a class of drugs known as histamine H2-receptor antagonists [1].
What is Ranitidine 150 mg used for?
Ranitidine 150 mg is prescribed to treat and prevent ulcers in the stomach and intestines, as well as to treat gastroesophageal reflux disease (GERD) and other conditions that cause too much stomach acid [1]. It helps relieve symptoms such as heartburn, stomach pain, and difficulty swallowing [1].
How does Ranitidine work?
Ranitidine works by blocking the action of histamine on parietal cells in the stomach lining. Histamine signals these cells to produce acid. By blocking histamine, ranitidine reduces the amount of acid secreted by the stomach [1].
What are the potential side effects of Ranitidine?
Common side effects can include headache, diarrhea, constipation, nausea, and stomach pain [1]. Less common but more serious side effects may occur. Patients should consult their healthcare provider if they experience any persistent or bothersome side effects [1].
Are there different strengths of Ranitidine?
Yes, ranitidine is available in various strengths, including 150 mg and 300 mg tablets, as well as oral solutions and injectable forms [1]. The prescribed dosage depends on the condition being treated [1].
What is the regulatory status of Ranitidine?
In April 2020, the U.S. Food and Drug Administration (FDA) requested that all prescription and over-the-counter (OTC) ranitidine products be removed from the market [2]. This action was taken due to the presence of unacceptable levels of N-nitrosodimethylamine (NDMA), a probable human carcinogen, in the drug [2]. Manufacturers subsequently recalled their ranitidine products [2].
