Zantac Oral

Zantac® (
 ranitidine hydrochloride) is a medication used for treating GERD (gastroesophageal reflux disease), certain types of ulcers, erosive esophagitis, and pathological hypersecretory conditions.
 
This medicine belongs to a class of drugs called H2 blockers. It works by blocking histamine (a chemical released by the body) in the stomach, which can help reduce the amount of acid the stomach produces.
 
Zantac is available in several different forms and strengths: oral tablets, EFFERdose® tablets (which are dissolved in water), and syrup. These products are available by prescription only. Two additional forms are available over-the-counter: Zantac 75 Acid Reducer and Maximum Strength Zantac 150 Acid Reducer. Zantac oral tablets, EFFERdose tablets, and syrup are taken one to four times a day, depending on the condition being treated.
