Pharmacological basis of drugs used in treatment of Acute Migraine

Q94 marksShort Answers

Answer

  • Triptans (Sumatriptan): 5-HT1B/1D agonists causing cranial vasoconstriction and inhibiting trigeminal neuropeptide release — first-line for moderate-severe acute attacks.
  • NSAIDs (Aspirin, Naproxen): inhibit prostaglandin synthesis, reducing neurogenic inflammation and pain — effective for mild-moderate attacks.
  • Antiemetics (Metoclopramide): counter associated nausea/vomiting and improve gastric emptying, aiding absorption of oral analgesics.
  • Ergot alkaloids: non-selective 5-HT agonists causing vasoconstriction — reserved for refractory attacks due to a higher adverse-effect burden.
