Question Title: Prilosec vs. Tagamet vs. Zantac

Dear Steve,

Cimetidine (Tagamet) and ranitidine (Zantac) belong to the same class of acid suppressing agents called histamine receptor antagonists and if given in equal doses work equivalently. On the other hand, omeperazole (Prilosec) and lansoprazole (Prevacid) are proton pump inhibitors and are very potent inhibitors of acid secretion. Most physicians will initially try cimetidine or ranitidine prior to considering the more costly proton pump inhibitors. Patients whose symptoms do not respond to histamine receptor antagonists will often obtain relief with proton pump inhibitors. In clinical trials where patients with erosive esophagitis and peptic ulcer disease are studied, patients report better symptom relief with proton pump inhibitors. Furthermore, faster healing rates are also seen with proton pump inhibitors. I hope you find this information helpful.
