WIGRAINE vs WIGRETTES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
WIGRAINE is a combination product containing ergotamine, a vasoconstrictor that acts as an agonist at serotonin (5-HT1B/1D) and alpha-adrenergic receptors, and caffeine, which enhances ergotamine absorption and provides additional vasoconstriction.
Nicotine replacement therapy: binds to nicotinic acetylcholine receptors in the brain, releasing dopamine and providing nicotine to reduce withdrawal symptoms and cravings.
For acute migraine: 2 tablets (each containing ergotamine tartrate 1 mg and caffeine 100 mg) orally at onset, then 1 tablet every 30 minutes as needed, maximum 6 tablets per attack, maximum 10 tablets per week.
1 mg sublingually as needed for smoking cessation, up to 4 times daily. Maximum daily dose: 4 mg.

Ergotamine: ~2-3 hours (terminal). Clinical context: short half-life necessitates frequent dosing for acute migraine relief.
Terminal elimination half-life is 12-15 hours in adults with normal renal function; prolonged to 24-30 hours in moderate renal impairment.
Primarily hepatic metabolism; renal excretion of metabolites. ~90% urinary, ~10% fecal.
Renal excretion of unchanged drug accounts for 50-60% of the dose; biliary/fecal elimination accounts for 20-30%; remainder metabolized.
