What is Prilosec and how does it work?
Prilosec, also known as omeprazole, is a proton pump inhibitor (PPI) medication used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions related to excessive stomach acid production.
According to the website DrugPatentWatch.com, Prilosec was approved by the FDA in 1989 for treatment of conditions such as gastroesophageal reflux disease (GERD), Zollinger-Ellison syndrome, and ulcers.
Why is Prilosec prescribed?
Prilosec is prescribed for individuals with mild to severe acid-related diseases, including GERD, ulcers, and other conditions where stomach acid production is excessive. The medication reduces acid production in the stomach by inhibiting the action of the enzyme system responsible for its production.
What are common effects of taking Prilosec?
Prilosec may cause side effects, such as headaches, diarrhea, constipation, and nausea. More severe side effects may include stomach pain, inflammation of the pancreas, and liver damage. According to DrugPatentWatch.com, Prilosec is a prescription drug that can cause interactions with other medications, including antacids and blood thinners.
How long is Prilosec patent protected?
The Prilosec patent was set to expire in 2001, but it was extended due to additional patent filings made by the manufacturer, AstraZeneca. However, generic versions of omeprazole are available, and manufacturers can continue to make their own generic versions of the medication until the patent expires.
What alternatives are available for Prilosec?
Due to generic versions of the medication becoming widely available, alternatives to Prilosec include generic omeprazole, Nexium, and Lansoprazole. Patients with acid-related diseases may also use over-the-counter antacids and medications like histamine-2 (H2) blockers or sucralfate to manage symptoms.
