Prilosec is a brand name for the generic drug omeprazole. It works by blocking the pumps in your stomach that produce acid. Zantac is a brand name for a different generic drug, ranitidine. Zantac blocks a chemical in your body called histamine that activates the acid pumps.

Both prescription Prilosec and Prilosec OTC contain the same active ingredient, omeprazole, which effectively stops acid production. Prescription Prilosec treats diseases that require diagnosis and supervision by a doctor. Prilosec OTC treats only symptoms of frequent heartburn.

Prilosec. Prilosec (omeprazole) is a proton pump inhibitor that treats severe stomach acid-related conditions like GERD.

Esomeprazole is the S-isomer of omeprazole. It is reported to have greater activity than the racaemic mixture (omeprazole) due to the significantly lower activity of the R-isomer. Therefore the same degree of acid suppression can be produced with lower doses of esomeprazole compared with omeprazole.

Relieves heartburn. Talk to your doctor or pharmacist about other medicines if you need additional relief. Zantac 75 (ranitidine) works well to relieve heartburn symtoms and is quite tolerable. You can take it in combination with a quick-acting antacid (like Maalox or Tums) if you need relief right away.

Ranitidine (also known by its brand name, Zantac, which is sold by the drug company Sanofi) is available both over the counter (OTC) and by prescription. It belongs to the class of drugs known as H2 (or histamine-2) blockers. OTC ranitidine is commonly used to relieve and prevent heartburn.

Protonix and Zantac belong to different drug classes. Protonix is a proton pump inhibitor (PPI) and Zantac is a H2 (histamine-2) receptor blocker. Protonix is available by prescription while Zantac is available over-the-counter (OTC) and as a generic.

Relieves heartburn. Pepcid (Famotidine) works well for heartburn but may not last as long or start working as quickly as other antacids. Zantac 75 (ranitidine) works well to relieve heartburn symtoms and is quite tolerable.

Ranitidine is used to treat ulcers of the stomach and intestines and prevent them from coming back after they have healed. This medication is also used to treat certain stomach and throat (esophagus) problems (such as erosive esophagitis, gastroesophageal reflux disease-GERD, Zollinger-Ellison syndrome).

Are Pepcid and Prilosec the Same Thing? Pepcid (famotidine) and Prilosec (omeprazole) are used to treat and prevent recurrence of stomach and duodenal ulcers. Pepcid is also useful in managing heartburn, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome.

Background: Lansoprazole (LAN) and omeprazole (OME) heal esophagitis effectively and to similar extents, but LAN has a faster effect on the relief of symptoms of gastroesophageal reflux. However, no strict comparison of the two proton pump inhibitors' effect on acid reflux and gastric acidity has been published.

Prilosec contains two isomers of the drug omeprazole, while Nexium only contains one isomer. Isomer is a term for a molecule that includes the same chemicals, but is arranged in a different way. So, you could say that omeprazole and esomeprazole are made of the same building blocks, but put together differently.

Drugs that do the latter are called proton pump inhibitors (PPI's). Examples include esomeprazole (Nexium) and lansoprazole (Prevacid). Drugs that do the former are called H2 blockers, and examples include cimetidine (Tagamet), ranitidine (Zantac), and famotidine (Pepcid).

Proton pump inhibitors — also called PPIs — reduce stomach acid by blocking the action of the parts of cells that produce acid. These drugs include the prescription and over-the-counter medications omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), esomeprazole (Nexium) and pantoprazole (Protonix).

Those drugs included omeprazole, which is found in the heartburn drug Prilosec and its generic versions. Those patients needed a higher thyroxine dose when they started taking omeprazole, the study shows. Low levels of stomach acid may bump up the required thyroxine dose, the researchers write.
