Prilosec (generic name: omeprazole; brand names include: Omez / Protoloc) is a proton pump inhibitor which decreases the amount of acid produced in the stomach.
Prilosec is used to treat ulcers, gastroesophageal reflux disease (GERD or heartburn), and other conditions involving excessive stomach acid production (e.g., Zollinger-Ellison syndrome, multiple endocrine adenomas and systemic mastocytosis).
This medication may be used in combination with antibiotics to treat certain types of ulcers caused by bacterial infection (H. pylori).
Prilosec is also used for preventing/treating damage to the stomach and upper part of the intestine caused by non-steroidal anti-inflammatory drugs.
Prilosec directly shuts down many active pumps over time that make acid, but leaves enough acid for digestion, with one pill a day, and can relieve heartburn at the source for up to 24 hours with one pill a day.
