Ranitidine tablets were used to treat conditions related to excess stomach acid [1]. These conditions included ulcers in the stomach and duodenum, gastroesophageal reflux disease (GERD), and erosive esophagitis [1][2]. They also helped prevent stomach ulcers from recurring [1].
What was ranitidine tablet used for?
Ranitidine tablets were prescribed to manage conditions where the stomach produced too much acid. This included treating active peptic ulcers, which are sores that can form in the lining of the stomach or the first part of the small intestine [1]. They were also used to treat GERD, a condition where stomach acid frequently flows back into the esophagus, causing heartburn and other symptoms [1][2]. Additionally, ranitidine helped in healing and preventing the recurrence of erosive esophagitis, which is damage to the lining of the esophagus caused by stomach acid [1].
Why was ranitidine tablet recalled?
Ranitidine tablets were recalled due to the presence of N-nitrosodimethylamine (NDMA), a probable human carcinogen [3]. NDMA was found to degrade over time in ranitidine products, leading to unacceptable levels of this impurity [3]. Regulatory agencies, including the U.S. Food and Drug Administration (FDA), issued recalls for ranitidine products because of these contamination concerns [3].
What are alternatives to ranitidine tablets?
Several alternatives are available for managing conditions previously treated with ranitidine tablets. These include other histamine-2 (H2) blockers, such as famotidine [4]. Proton pump inhibitors (PPIs), like omeprazole, lansoprazole, and pantoprazole, are also commonly used and are generally more effective at reducing stomach acid production than H2 blockers [4]. Over-the-counter antacids can provide temporary relief for mild heartburn [5].
When did ranitidine tablets become unavailable?
Ranitidine products, including tablets, were largely removed from the market starting in late 2019 and into 2020 following recalls issued by manufacturers and the FDA due to NDMA contamination [3][6].
What were the side effects of ranitidine?
While generally considered safe when it was available, ranitidine tablets could cause side effects. These included headache, constipation, diarrhea, nausea, and abdominal pain [1]. Less common side effects could involve dizziness or rash [1]. The primary concern leading to its removal was the risk of NDMA contamination, not typical side effects of the drug itself [3].
Who manufactured ranitidine tablets?
Ranitidine was originally developed by GlaxoSmithKline (GSK) and sold under the brand name Zantac [7]. Following patent expiry, many generic manufacturers also produced ranitidine tablets.
How did ranitidine tablets work?
Ranitidine belongs to a class of drugs called H2 receptor antagonists [1]. It worked by blocking the action of histamine on the parietal cells in the stomach lining [1]. Histamine stimulates these cells to produce stomach acid, so by blocking its effects, ranitidine significantly reduced the amount of acid secreted [1].
