NSAID

NSAIDs Overview

  • NSAID Definition: NSAID stands for Non-Steroidal Anti-Inflammatory Drug. These drugs are designed for pain management through the reduction of inflammation.

  • Mechanism of Action: They work by blocking prostaglandin synthesis, which is involved in the inflammatory response at the site of trauma.

Common NSAIDs

  • Generic Non-Selective NSAIDs:

    • Ibuprofen

    • Naproxen

    • Ketorolac

  • COX-2 Inhibitors: A subclass of NSAIDs that typically do not irritate the stomach lining and are available by prescription.

    • Example: Celecoxib

  • Aspirin Salicylate:

    • Classified as an NSAID, but functions primarily as an antiplatelet agent.

Adverse Effects

  • Common Side Effects:

    • Headache

  • Contraindications:

    • Patients with bleeding disorders may see widespread adverse effects since NSAIDs interfere with platelet function.

    • Those with infections should not take NSAIDs as they can mask infection symptoms.

    • All NSAIDs (except aspirin) can elevate the risk of heart attack or stroke.

    • 3,200 mg per day in equally divided doses.
