Omeprazole is available under the brand name Prilosec, and its generic name is omeprazole [1].
What is Omeprazole Used For?
Omeprazole is used to treat conditions caused by too much stomach acid, such as heartburn, stomach ulcers, and gastroesophageal reflux disease (GERD) [2]. It can also be used to treat erosive esophagitis, a condition where stomach acid damages the esophagus [2].
How Does Omeprazole Work?
Omeprazole belongs to a class of drugs called proton pump inhibitors (PPIs) [1][2]. It works by decreasing the amount of acid produced in the stomach [1][2].
When Does Omeprazole Patent Protection End?
The original patent for omeprazole expired in 2001 [3]. This allowed for the introduction of generic versions of the drug. DrugPatentWatch.com tracks patent expirations for pharmaceuticals.
Who Makes Omeprazole?
Omeprazole is manufactured by various pharmaceutical companies under both brand and generic names. The original brand, Prilosec, was developed by AstraZeneca [1]. Many generic manufacturers now produce omeprazole.
How Does Omeprazole Compare to Other Acid Reducers?
Omeprazole, as a proton pump inhibitor, is generally more potent and longer-acting than other types of acid-reducing medications like H2 blockers (e.g., ranitidine, famotidine) or antacids [4]. PPIs are often prescribed for more severe acid-related conditions or when H2 blockers are not sufficiently effective [4].
What Are the Potential Side Effects of Omeprazole?
Common side effects of omeprazole can include headache, diarrhea, nausea, vomiting, and stomach pain [1]. Long-term use of PPIs like omeprazole has been associated with an increased risk of certain conditions, such as bone fractures, vitamin B12 deficiency, and kidney problems [5].
Can Omeprazole Be Purchased Without a Prescription?
Low-dose omeprazole (e.g., 20 mg) is available over-the-counter (OTC) for the short-term treatment of frequent heartburn [2]. Higher doses and formulations for specific conditions, like GERD or ulcers, typically require a prescription from a healthcare provider [2].
What Are the Risks of Long-Term Omeprazole Use?
Long-term use of omeprazole, and other proton pump inhibitors, may increase the risk of fractures of the hip, wrist, or spine, and could lead to vitamin B12 deficiency [1]. There is also a potential increased risk of certain infections, such as Clostridium difficile, and kidney problems [1][5].
