Ranitidine oral syrup is a medication used to reduce the amount of acid produced in the stomach [1]. It is a histamine H2-receptor antagonist that works by blocking the action of histamine, a substance that stimulates stomach acid production [2].
What conditions does ranitidine oral syrup treat?
Ranitidine oral syrup is prescribed for the treatment of peptic ulcers (gastric and duodenal), gastroesophageal reflux disease (GERD), and erosive esophagitis [3]. It can also be used to prevent stomach ulcers associated with certain medications and to treat conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome [4].
How does ranitidine work?
Ranitidine acts by inhibiting the binding of histamine to H2 receptors on the parietal cells in the stomach lining. These receptors are responsible for signaling the cells to produce acid. By blocking histamine, ranitidine effectively reduces the secretion of gastric acid [2].
What are the potential side effects of ranitidine oral syrup?
Common side effects of ranitidine can include headache, dizziness, diarrhea, constipation, and nausea [5]. Less common side effects may involve rash, itching, and fatigue [5]. It is important to consult a healthcare professional for a complete list of potential side effects and to discuss any concerns.
When did ranitidine get removed from the market?
In April 2020, the U.S. Food and Drug Administration (FDA) requested the withdrawal of all prescription and over-the-counter (OTC) ranitidine products from the U.S. market [6]. This action was taken due to the presence of unacceptable levels of N-Nitrosodimethylamine (NDMA), a probable human carcinogen, in ranitidine products [6]. Concerns about NDMA contamination had been ongoing, leading to voluntary recalls and the eventual market withdrawal [6].
What are alternatives to ranitidine oral syrup?
Following the market withdrawal of ranitidine, alternative medications are available to manage conditions like GERD and peptic ulcers. These include other H2-receptor antagonists like famotidine and cimetidine, as well as proton pump inhibitors (PPIs) such as omeprazole, esomeprazole, and lansoprazole [7]. Patients should consult with their healthcare provider to determine the most appropriate alternative for their specific needs.
What is the difference between ranitidine and famotidine?
Both ranitidine and famotidine are H2-receptor antagonists used to reduce stomach acid. Famotidine is a more potent H2 blocker than ranitidine and has a longer duration of action [8]. Famotidine is also available in various formulations, including oral tablets and oral suspension, and has not been associated with the NDMA contamination issues that led to ranitidine's withdrawal [7][8].
What are the risks of NDMA in medications?
N-Nitrosodimethylamine (NDMA) is classified as a probable human carcinogen. Exposure to NDMA can occur through diet, water, and certain medications [6]. While low levels of NDMA are often found in the environment and some foods, the presence of unacceptable levels in pharmaceuticals raises concerns about potential long-term health risks, including an increased risk of cancer [6].
