Glecaprevir/Pibrentasvir (Mavyret)
Pan-genotypic fixed-dose combination DAA for chronic hepatitis C: glecaprevir 100 mg (NS3/4A protease inhibitor) + pibrentasvir 40 mg (NS5A inhibitor). Dose: three tablets PO once daily with food for 8 weeks in treatment-naive non-cirrhotic or compensated cirrhotic patients (12-16 weeks in treatment-experienced). Pibrentasvir terminal half-life ~23h; glecaprevir ~6h with food-enhanced absorption. SVR12 >95% across genotypes 1-6 (ENDURANCE, EXPEDITION). Contraindicated in decompensated cirrhosis (hepatic PK risk).
Projected serum levels — 3 pill (≈ 420 mg), once daily
Maintenance schedule: 3 pill (≈ 420 mg) once daily (oral).
Modeled steady state after ~1 days: peak ≈ 159 mg, trough ≈ 8.2 mg body load. Population-based estimate over 15 days for a reference dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
