Is prilosec otc the same as nexium - Prilosec vs. Nexium
It's important for the proton pump to shoot the hydrogen out of the parietal cell before it turns into acid. Gastrointestinal lining is the only tissue in the body built to handle potentially lethal hydrochloric acid.
If the parietal cell manufactured hydrochloric acid inside itself -- as cells do when they make most other compounds -- the acid would kill the cell, digesting it from the inside out instead of digesting the pork chop you just ate.
The molecules of omeprazole and esomeprazole plug up the "valve" of the proton pump, meaning it can't release hydrogen ions into the stomach, which results in less acid. Esomeprazole -- the newer, more advanced of the two -- is an isomer of omeprazole. This means it's got all the same types and numbers of atoms in the molecule, they're just stuck together in a different way, so Prilosec and Nexium are nearly identical on a chemical level.

That slight structural change makes a difference, though. If we continue thinking of the proton pump as a valve, Nexium forms a tighter seal when it plugs up the proton pump. The result is that even a double dose of Prilosec isn't as effective at acid control as a single dose of Nexium, according to a study.
H2R blockers plug up a protein on parietal cell outer membranes that is set up to receive the messenger chemical called histamine, which is used to initiate all sorts of processes throughout the body.

When histamine is inserted into the receptor protein -- called the H2 receptor -- it begins the process of acid production.
PPIs -- which stop acid production in the final step rather than the first step -- tend to do a better job at acid control, partly because people quickly develop a tolerance for H2R antagonists after repeated dosing, is prilosec otc the same as nexium, according to a study.
Antacids mix with and neutralize stomach acid after it's already in the stomach cavity. They work fast, but don't last long.
