Zantac: Uses, Dosage, Price, Side Effects, Precautions & More

What is Zantac 150?

There are many drugs with a high therapeutic index including histamine-2 receptor antagonists (ranitidine). Ranitidine (Zantac) does not inhibit CYPs and is thus generally a better alternative to cimetidine for acid blocking therapy. Histamine-2 receptor antagonists are widely used in the treatment of GERD. These drugs have a very good safety record and are available over the counter as well as by prescription.
