Sumatriptan (Imitrex)
Selective serotonin 5-HT1B/1D receptor agonist for acute migraine treatment. Available as oral, subcutaneous, and nasal formulations. Oral bioavailability only 14% due to first-pass metabolism; subcutaneous bioavailability is 96%. Does not prevent migraines; used only for acute attacks.
Projected serum levels — 50 mg, as needed (shown daily)
Maintenance schedule: 50 mg as needed (shown daily) (oral).
Modeled steady state after ~1 days: peak ≈ 4.0 mg, trough ≈ 0.013 mg body load. Population-based estimate over 15 days for a 50 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
