Both sildenafil and the metabolite have terminal half lives of about 4 hours, viagra 50mg instructions. Mean sildenafil plasma concentrations measured after the administration of a single oral dose of mg to healthy male volunteers is depicted below: Maximum observed plasma concentrations are reached instruction 30 to minutes median 60 minutes of oral dosing in the fasted state. The mean steady state volume of distribution Vss for sildenafil is L, indicating instruction into the tissues.

Protein binding is independent of total drug concentrations. Based upon measurements of sildenafil in semen of healthy volunteers 90 minutes after dosing, less than 0. The major circulating metabolite results from N-desmethylation of sildenafil, and is itself further metabolized.

Similar values for pharmacokinetic parameters were seen in normal volunteers and in the patient population, using a population 50mg approach.

50mg is consistent with ritonavir's marked effects on a broad range of P substrates.

In a study of healthy male volunteers, viagra 50mg instructions, co-administration of sildenafil at steady state 80 mg t.
