Zantac vs. Pepcid: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 14, 2023
Zantac (ranitidine) and Pepcid (famotidine) are both medications used to reduce and manage stomach acid but differ in chemical composition and availability due to Zantac's recall over safety concerns.
Key Differences
Zantac, which is a brand name for the drug ranitidine, belongs to the class of drugs known as H2 blockers. Its primary function is to decrease the amount of acid produced by the stomach, which in turn can prevent and relieve heartburn, an acid reflux condition. Pepcid, conversely, is the brand name for famotidine, and although it is also an H2 blocker with a similar function to Zantac, it has a different chemical composition and structure.
Both Zantac and Pepcid have been utilized over the years to treat conditions like peptic ulcers, gastroesophageal reflux disease (GERD), and conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome. However, it’s vital to note that despite their similarities in applications, they do not share identical pharmacological profiles and have various dosage forms and strengths.
It is pivotal to note that Zantac was recalled from the market due to concerns that it may contain a probable carcinogenic contaminant known as N-nitrosodimethylamine (NDMA). Pepcid, however, has not faced such recalls and remains available on the market as a viable option for those seeking an H2 blocker. This fundamental difference currently impacts the availability and user choice between these two drugs.
Zantac and Pepcid can both be utilized in either prescription or over-the-counter (OTC) form depending on the nature and severity of the condition being treated. In the case of Zantac, prior to its recall, and Pepcid, they are both available in various forms including tablets, injection, and oral solutions, providing flexibility for usage.
To understand and select between Zantac and Pepcid, healthcare professionals typically would consider various factors, such as the patient’s medical history, the condition being treated, and potential side effects. Both drugs have been widely recognized in the medical community, yet due to the recent developments regarding safety concerns, Pepcid is often more predominantly prescribed nowadays.
