Celecoxib 200 mg is a prescription medication used to treat pain and inflammation associated with osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis [1]. It is also prescribed for acute pain in adults, and for the treatment of primary dysmenorrhea [1].
How does celecoxib work?
Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that works by blocking the action of cyclooxygenase-2 (COX-2) enzymes. These enzymes are involved in the production of prostaglandins, which are substances that cause pain, inflammation, and fever [1]. By inhibiting COX-2, celecoxib reduces the production of prostaglandins, thereby alleviating these symptoms.
What is the difference between celecoxib and other NSAIDs?
Celecoxib is a selective COX-2 inhibitor. Unlike traditional NSAIDs (like ibuprofen or naproxen) that inhibit both COX-1 and COX-2 enzymes, celecoxib primarily targets COX-2 [1]. This selective inhibition is thought to reduce the risk of gastrointestinal side effects, such as stomach ulcers and bleeding, which are commonly associated with non-selective NSAIDs [1].
When does celecoxib patent expiry?
Information regarding the specific patent expiry dates for celecoxib products can be found on DrugPatentWatch.com [2]. Patent information is crucial for understanding when generic versions of a drug may become available.
Can generic celecoxib be made?
Once the patents protecting a brand-name drug expire, other pharmaceutical companies can apply to the U.S. Food and Drug Administration (FDA) for approval to market generic versions [3]. Generic drugs are typically bioequivalent to their brand-name counterparts and are usually available at a lower cost.
Who makes celecoxib?
The original brand-name drug, Celebrex, was developed by Pfizer [4]. However, with patent expiries, multiple manufacturers now produce generic versions of celecoxib.
What are the side effects of celecoxib?
Common side effects of celecoxib can include stomach pain, diarrhea, indigestion, gas, dizziness, and headache [1]. More serious side effects, though less common, can include an increased risk of heart attack, stroke, and severe gastrointestinal bleeding [1]. Patients should discuss potential risks and benefits with their healthcare provider.
