Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever [1]. It is available in various forms, including oral tablets, capsules, and liquid suspensions, and can be purchased over-the-counter or by prescription [1].
How does naproxen work?
Naproxen works by inhibiting the activity of cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. These enzymes are responsible for producing prostaglandins, which are chemicals in the body that contribute to pain, inflammation, and fever [1]. By blocking prostaglandin production, naproxen effectively reduces these symptoms.
What conditions is naproxen used for?
Naproxen is commonly prescribed or recommended for a range of conditions, including [1, 2]:
* Arthritis: Osteoarthritis, rheumatoid arthritis, and psoriatic arthritis.
* Pain relief: Mild to moderate pain, such as menstrual cramps, headaches, muscle aches, and backaches.
* Inflammatory conditions: Bursitis, tendonitis, and gout flares.
* Fever reduction.
How does naproxen compare to ibuprofen?
Both naproxen and ibuprofen are NSAIDs and work in a similar manner. However, naproxen generally has a longer duration of action, meaning it may be taken less frequently than ibuprofen [3]. This can make naproxen a convenient option for managing chronic pain or inflammation that requires consistent relief throughout the day. The choice between naproxen and ibuprofen often depends on individual response, specific condition, and healthcare provider recommendations.
What are the potential side effects of naproxen?
Like other NSAIDs, naproxen can cause side effects, though not everyone experiences them. Common side effects include [1]:
* Upset stomach or indigestion
* Nausea
* Heartburn
* Dizziness
* Headache
More serious side effects, though less common, can include stomach ulcers, gastrointestinal bleeding, kidney problems, and increased risk of heart attack or stroke [1]. It is important to use the lowest effective dose for the shortest duration necessary and to discuss any concerns with a healthcare professional.
When does naproxen patent protection expire?
Naproxen has been available for many years, and its original patents have long since expired [4]. This means that generic versions of naproxen are widely available, contributing to its affordability and accessibility. Information on the patent status of specific formulations or new uses of naproxen can be found on resources like DrugPatentWatch.com [4].
Who makes naproxen?
Since its original patents have expired, numerous pharmaceutical companies manufacture and market naproxen. It is available under brand names such as Aleve and Naprosyn, as well as numerous generic labels [1, 5].
