Glecaprevir
Pan-genotypic HCV NS3/4A protease inhibitor; component of Mavyret (glecaprevir/pibrentasvir). 8-12 week curative course. Significant OATP1B1 and P-gp substrate; CYP3A-mediated metabolism.
Projected serum levels — 300 mg, once daily
Maintenance schedule: 300 mg once daily (oral).
Modeled steady state after ~1 days: peak ≈ 113 mg, trough ≈ 18.0 mg body load. Population-based estimate over 15 days for a 300 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
