Which proton-pump inhibitor is best? Nexium, (esomeprazole) Prilosec, or Prevacid and why?

Each has relative... ...merits based on duration of action, side effects, tolerance, cost/insurance coverage. All are equally efficacious, so your question should be better phrased, "which is better for me?", and that we can't answer since we don't know your particular circumstances.
None! The plethorta of side effects of these drugs has only become evident. Nutritional deficiencies, osteoporosis, chronic kidney issues, and acelerated heart disease. They should be short term. H2 blockers are a preferred treatment!

Is there any difference between PPI drugs like prilosec, nexium, (esomeprazole) prevacid, etc?

Not at all. No they are all, as you said PPI's and appear to provide similar relief. Some are more expensive than others and drug companies would like you to believe their PPI works better than the generic. It is my belief that in general, you should stick with generic medications. Do not fall for the marketing hype. Read more...

I have acid relfux (acid coming up). PPIs (Prilosec, Nexium, and Prevacid) give dizziness and swelling in my throat. Doc won't put me on prescription. Zantac and Pepcid isn't strong enough. No h.pylori. Should I take ppi regardless of side effects?

Reflux. Have you tried strict dietary measures like avoidance of caffeine, alcohol,nicotine,spices, and greasy foods which can loosen the sphincter or valve between the stomach contents and esophagus? You could try taking gaviscon as a preventative of gerd. Sometimes symptoms are not due to acid reflux but due to bile reflux which doesn't respond to ppi's or zantac (ranitidine). Read more...
Acid reflux treatmen. The meds you listed all work by reducing the amount of acid secreted into your stomach. Why don't you take a liquid chemical base which will neutralize the acid in your mouth, esophagus & stomach. That is why you should have stayed more awake in HS chemistry class! Read more...

Taken Nexium, (esomeprazole) generic Nexium, (esomeprazole) and Protonix which cause drowsiness. Would it be worth taking Prevacid or Prilosec? Will tired feeling go away with time

Doubtful. None of the actions of any of these drugs would have anything to do with drowsiness. That is a very uncommon side effect of any of them. BUT Prilosec is well known to gum up the liver's ability to get other drugs out of you including all sedatives including alcohol.... so .. that one is doubly out. Otherwise, while I cannot explain why these drugs do that on you, the entire group is similar. Read more...

Do you have to stop taking a proton pump inhibitor like Prilosec two weeks before a h. Pylori biopsy?

H. Pylori. In general u are not asked to stop ppi for h. Pylori biopsy. Ppi can suppress h pylori in the antrum of the stomach but it may migrate to the body. Biopsies should be taken from the body of the stomach too. Read more...

Is there any treatment for a double pylorus besides pump inhibitors like Prilosec and prevacid (lansoprazole). Need answers?

Usually no therapy. Most commonly a double pylorus is due to prior ulcer disease. If there is ongoing ulcer disease than a proton pump inhibitor (eg Prilosec or prevacid) is the standard of care. If you have ulcer disease, a test for helicobacter pylori should be done. If there is no ulcer than no therapy for the double pylorus is required. Read more...
