The Identity of the Pink 'P75' Pill
The pink, round pill with the imprint 'P75' was identified as Ranitidine Hydrochloride 75 mg, a now-recalled medication previously available over-the-counter and by prescription. The manufacturer of one of the versions of this pill was Dr. Reddy's Laboratories Inc. Ranitidine was a popular medication sold under the brand name Zantac and its generics, belonging to a class of drugs known as H2 antagonists or H2 blockers.
How H2 Antagonists Like Ranitidine Worked
H2 blockers function by reducing the amount of acid produced by the stomach. They do this by blocking histamine from binding to H2 receptors in the stomach lining, which signals the stomach to produce acid. This mechanism of action provided relief from symptoms of heartburn and helped heal ulcers caused by excessive stomach acid.
Ranitidine was commonly used to treat a variety of conditions, including:
- Gastroesophageal Reflux Disease (GERD)
- Erosive Esophagitis
- Duodenal and gastric ulcers
- Zollinger-Ellison Syndrome
- Heartburn and indigestion
The Ranitidine Recall: The NDMA Contamination Problem
In 2020, the FDA requested that all manufacturers withdraw all prescription and over-the-counter ranitidine products from the market. This was not due to the drug itself being unsafe but because of potential contamination with N-nitrosodimethylamine (NDMA). NDMA is a probable human carcinogen, meaning it is suspected of causing cancer.
What happened to ranitidine?
The recall was triggered by the discovery that the NDMA levels in some ranitidine products could increase over time, especially when stored at higher-than-normal temperatures. While low levels of NDMA are found in some foods and water and are not considered a significant risk, the levels found in ranitidine were deemed unacceptable and posed a potential long-term risk to patients.
The FDA emphasized that the immediate risk to patients taking ranitidine was considered low. However, out of an abundance of caution, the decision was made to remove all ranitidine products from the market to prevent further exposure to potentially harmful levels of NDMA.
Safer Alternatives to the Pink P75 Pill
With ranitidine no longer available, doctors now recommend other medications to treat conditions formerly managed by the pink P75 pill. These alternatives are considered safe and effective and fall into a couple of different drug classes. The most common are other H2 blockers and proton pump inhibitors (PPIs).
Comparison of Ranitidine vs. Current Alternatives
| Feature | Ranitidine (P75, Recalled) | Famotidine (Pepcid, Current) | Omeprazole (Prilosec, Current) |
|---|---|---|---|

| Mechanism | Blocks histamine from stimulating stomach acid production. | Blocks histamine from stimulating stomach acid production. | Permanently blocks the enzyme system that produces stomach acid. |
| Onset | Works quickly, often within 30 minutes to an hour. | Works quickly, similar to ranitidine. | Takes longer to reach full effect, often 1-4 days. |
| Duration | Effects typically last for 8-12 hours. | Effects typically last for 8-12 hours. | Provides longer-lasting acid control, up to 24 hours. |

| Primary Uses | GERD, heartburn, ulcers. | GERD, heartburn, ulcers. | Severe GERD, ulcers, and more serious acid-related disorders. |
Conclusion: Prioritize Professional Medical Advice
The pink pill with 'P75' was identified as Ranitidine 75mg, a medication that is no longer on the market due to a nationwide recall concerning potential NDMA contamination. While Ranitidine was an effective treatment for acid reflux and related conditions, patients should never attempt to take recalled or unidentified medication. For those who were previously taking ranitidine, consulting a healthcare provider to discuss safe and currently available alternatives is the recommended course of action. Medications like famotidine and omeprazole offer effective treatment options and have not been subject to the same safety concerns as ranitidine. The recall of ranitidine serves as a crucial reminder of the importance of pharmaceutical safety and the need for ongoing vigilance regarding the medications we take.
