Umair Ahmad: Aspirin for Relief Protection and Prevention

Umair Ahmad, Pharmacist (Intern) at Waseem Pharmacy and Patient Counselling Centre, shared a post on LinkedIn:

Aspirin (Acetylsalicylic Acid)

Aspirin is a widely used non-steroidal anti-inflammatory drug (NSAID).

It has four main actions:

  • Analgesic – relieves pain
  • Antipyretic – reduces fever
  • Anti-inflammatory – decreases inflammation
  • Antiplatelet – prevents blood clot formation

Mechanism of action:

Aspirin irreversibly inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing the production of prostaglandins (responsible for pain, fever, and inflammation) and thromboxane A₂ (which promotes platelet aggregation). This antiplatelet effect lasts for the life of the platelet (about 7–10 days).

Uses:

  • Mild to moderate pain (headache, toothache, muscle pain)
  • Fever
  • Inflammatory diseases such as rheumatoid arthritis
  • Prevention and treatment of heart attack
  • Prevention of ischemic stroke and transient ischemic attack (TIA)
  • Prevention of blood clots after certain heart procedures

Common doses:

  • Pain or Fever: 325–650 mg every 4–6 hours as needed.
  • Antiplatelet (heart protection): Low-dose aspirin 75–100 mg once daily (commonly 81 mg or 75 mg), only when prescribed by a healthcare professional.

Side effects:

  • Stomach irritation
  • Nausea or indigestion
  • Gastric ulcer
  • Gastrointestinal bleeding
  • Easy bruising or prolonged bleeding
  • Ringing in the ears (tinnitus), especially with high doses

Contraindications:

Do not use aspirin in:

  • Active stomach ulcer or gastrointestinal bleeding
  • Aspirin allergy
  • Bleeding disorders (e.g., hemophilia)
  • Severe liver or kidney disease
  • Children or teenagers with viral illnesses (risk of Reye syndrome)
  • Late pregnancy unless specifically prescribed

Important drug interactions

  • Other NSAIDs (e.g., ibuprofen)
  • Anticoagulants (e.g., warfarin)
  • Corticosteroids
  • Alcohol (increases bleeding risk)”
