Dosing
Pulmonary arterial hypertension 40 mg (two 20 mg tablets) once daily with or without food; dividing the dose over the course of the day is not recommended. Start at 20 mg once daily for mild or moderate renal impairment (creatinine clearance 31 to 80 mL/min), increasing to 40 mg based on tolerability; avoid use in severe renal impairment. Start at 20 mg once daily for mild or moderate hepatic impairment (Child Pugh Class A or B); avoid in severe hepatic impairment. For patients on ritonavir >=1 week, start at 20 mg once daily and increase to 40 mg based on tolerability.
Pulmonary arterial hypertension Starting dose 0.125 mg TID or 0.25 mg BID with food; titrate by 0.125 mg TID or 0.25-0.5 mg BID no more frequently than every 3-4 days; maximum daily dose 120 mg.
Contraindications
- Concomitant use of any form of organic nitrate, regularly or intermittently

Pharmacology
Tadalafil is a selective inhibitor of phosphodiesterase type 5 (PDE5), the enzyme responsible for degradation of cyclic guanosine monophosphate (cGMP) in pulmonary vascular smooth muscle; by inhibiting PDE5, tadalafil increases cGMP concentrations, resulting in relaxation of pulmonary vascular smooth muscle cells and vasodilation of the pulmonary vascular bed.
Prostacyclin mimetic; treprostinil causes direct vasodilation of pulmonary and systemic arterial vascular beds, inhibits platelet aggregation, and inhibits smooth muscle cell proliferation.
