产品详细信息

详细说明 (English)

• Drug Groups: approved
• Description: An anti-inflammatory agent with analgesic and antipyretic properties. Both the acid and its sodium salt are used in the treatment of rheumatoid arthritis and other rheumatic or musculoskeletal disorders, dysmenorrhea, and acute gout. [PubChem]
• Indication: For the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, tendinitis, bursitis, and acute gout. Also for the relief of mild to moderate pain and the treatment of primary dysmenorrhea.
• Pharmacology: Naproxen is a member of the arylacetic acid group of nonsteroidal anti-inflammatory drugs (NSAIDs). Naproxen has analgesic and antipyretic properties. As with other NSAIDs, its mode of action is not fully understood; however, its ability to inhibit prostaglandin synthesis may be involved in the anti-inflammatory effect.
• Toxicity: ORAL (LD₅₀): Acute: 248 mg/kg [Rat]. 360 mg/kg [Mouse]. Symptoms of overdose include drowsiness, heartburn, indigestion, nausea, and vomiting.
• Affected Organisms: Humans and other mammals
• Biotransformation: Naproxen is extensively metabolized to 6-0-desmethyl naproxen and both parent and metabolites do not induce metabolizing enzymes.
• Absorption: Naproxen itself is rapidly and completely absorbed from the GI tract with an in vivo bioavailability of 95%. Although naproxen itself is well absorbed, the sodium salt form is more rapidly absorbed resulting in higher peak plasma levels for a given dose. Food causes a slight decrease in the rate absorption.
• Half Life: The observed terminal elimination half-life is approximately 15 hours.
• Protein Binding: At therapeutic levels naproxen is greater than 99% albumin-bound.
