Ranitidine 150 mg tablets were primarily used to treat and prevent ulcers in the stomach and intestines [1]. They were also prescribed to manage gastroesophageal reflux disease (GERD) and conditions causing the stomach to produce too much acid, such as Zollinger-Ellison syndrome [1].
What conditions did Ranitidine 150 mg tablets treat?
Ranitidine 150 mg tablets were indicated for a range of acid-related gastrointestinal issues. These included the healing of duodenal and gastric ulcers, as well as the prevention of their recurrence [1]. The medication was also used to treat erosive esophagitis associated with GERD [1]. Furthermore, it helped alleviate symptoms of heartburn and indigestion by reducing stomach acid production [1].
Why was Ranitidine taken off the market?
The voluntary recall and subsequent market withdrawal of ranitidine products, including 150 mg tablets, occurred due to concerns about the presence of N-nitrosodimethylamine (NDMA) [2]. NDMA is classified as a probable human carcinogen, and tests indicated that ranitidine formulations could degrade over time, forming unacceptable levels of this impurity [2][3]. Regulatory agencies worldwide, including the U.S. Food and Drug Administration (FDA), requested these recalls [2].
What are the alternatives to Ranitidine 150 mg tablets?
Following the withdrawal of ranitidine, several alternative medications are available for managing acid-related conditions. These include other H2 blockers and proton pump inhibitors (PPIs). Common alternatives include famotidine, cimetidine, and omeprazole, lansoprazole, and pantoprazole [4]. These drugs work by reducing the amount of acid produced in the stomach, offering similar therapeutic benefits to ranitidine [4].
How do H2 blockers like Ranitidine work?
Ranitidine is a histamine H2-receptor antagonist. It works by blocking the action of histamine at H2 receptors in the parietal cells of the stomach [1]. Histamine stimulates these cells to produce acid. By blocking this stimulation, ranitidine effectively decreases the amount of acid secreted into the stomach, thereby reducing acidity and allowing ulcers to heal and symptoms to subside [1].
