The Zantac Recall and What You Can Do About GERD

April 20, 2020

Zantac (generic name ranitidine) is a common antacid which has been in use for years. It belongs to the same class at Pepcid, Tagamet, and Axid. It is a different class of drug as Prilosec, Protonix, Dexilent, and Nexium. Zantac has IV and oral forms. It has been used for the treatment of GERD/heartburn, ulcers, gastritis.

The Food and Drug Administration recently revealed that Zantac contains low levels of a cancer-causing contaminant known as N-Nitrosodimethylamine (NDMA). NDMA was previously identified in a blood pressure drug, leading to recalls. NDMA is associated with increased risk of cancers of the liver, stomach, bladder, kidney, and other organs. The risk is likely higher with prolonged exposure to NDMA. The agency determined that the impurity in some ranitidine products increases over time and when stored at higher than room temperatures.

The Gastric Sleeve Procedure

June 21, 2013

The gastric sleeve procedure also known as the sleeve gastrectomy is one of the fastest growing major bariatric surgery procedure available today. The gastric sleeve has become very popular with patients and surgeons alike because of its straightforwardness and simplicity. While it is still major surgery, it only requires the removal of about 70-80% of the stomach. The restriction that this procedure provides means that patients will feel fuller sooner and will not be able to eat as much as they once could. Once the food has been processed by the new, smaller stomach pouch, it is digested in much the same way as it was beforehand, as there is no rerouting of the small intestine. Also, no medical device is implanted in the abdomen.
