Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, swelling, tenderness, and inflammation [1]. It is commonly used for conditions such as arthritis, gout, menstrual cramps, and tendinitis [1].
What kind of pain does naproxen sodium treat?
Naproxen sodium is effective for mild to moderate pain [1]. This includes pain associated with various inflammatory conditions like rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout, and tendinitis [1]. It is also frequently used for menstrual cramps (dysmenorrhea) [1].
How does naproxen sodium work?
Naproxen sodium works by blocking the production of prostaglandins, which are hormone-like substances in the body that trigger inflammation, pain, and fever [1]. By inhibiting the enzymes cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), naproxen sodium reduces the synthesis of these prostaglandins, thereby alleviating symptoms [1].
How long does naproxen sodium take to work?
For acute pain, naproxen sodium typically begins to relieve symptoms within an hour of taking a dose [2]. The full effect may take longer to be noticed [2]. For chronic conditions like arthritis, it may take several weeks of consistent use to achieve maximum pain relief [1].
Are there different strengths of naproxen sodium available?
Naproxen sodium is available in various strengths, commonly in over-the-counter (OTC) formulations and prescription strengths [3]. OTC strengths are typically 220 mg per tablet [3]. Prescription strengths can be higher, such as 275 mg, 500 mg, and 550 mg, depending on the condition being treated [3].
What are the risks or side effects of naproxen sodium?
Like other NSAIDs, naproxen sodium carries potential risks. These include stomach bleeding, ulcers, and perforation [1]. It can also increase the risk of heart attack, stroke, and high blood pressure [1]. Other common side effects can include heartburn, nausea, stomach pain, dizziness, and headache [1]. It is important to use the lowest effective dose for the shortest duration necessary to minimize these risks [1].
When does the patent on naproxen sodium expire?
Naproxen sodium has been available as a generic medication for many years, meaning its original patents have long expired [4]. This has allowed for the widespread availability of generic naproxen sodium at lower costs [4].
Who makes generic naproxen sodium?
Numerous pharmaceutical companies manufacture generic versions of naproxen sodium. These can include major generic drug producers and smaller regional manufacturers [5].
What is the difference between naproxen and naproxen sodium?
Naproxen sodium is a salt form of naproxen. The sodium salt is designed to be absorbed more quickly into the bloodstream, potentially leading to faster pain relief compared to naproxen itself [6]. However, both contain the active ingredient naproxen and work by the same mechanism [6].
