- Mechanism of Action: Inhibition of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5)
- Pharmacokinetics and Metabolism:
- Mean absolute bioavailability of 41%
- Elimination predominantly by hepatic metabolism
- Converted to an active metabolite with properties similar to the parent
- Terminal half lives of about 4 hours
- Absorption and Distribution:
- Rapid absorption
- Maximum observed plasma concentrations reached within 30 to 120 minutes
- Metabolism and Excretion:
- Cleared by hepatic microsomal isoenzymes
