Strenuous exercise was also discouraged.On the evening before dosing, the subjects entered the study centre and abstained from food and drink (except water) from 22:00 onward.
The protocol for each period was identical to that of the food‐effect study, except that sildenafil doses were administered as a 25‐mg, 50‐mg or 100‐mg tablet, or as two 100‐mg tablets, taken with 240 ml of water.In the absolute bioavailability study, blood samples sufficient to provide 3 ml of plasma for pharmacokinetic analyses were collected in the morning prior to PO and IV dosing of sildenafil. Center for Drug Evaluation and Research, Food and Drug Administration. 1 4 91 117 127 130 203 Duration Sildenafil was supplied as one 100‐mg tablet for each study period. FDA alert for healthcare professionals: tadalafil.
The half‐life of sildenafil provides for an appropriate duration of therapeutic effect and also prevents drug accumulation with chronic once‐daily use. The absolute bioavailability was 41% due to first‐pass metabolism.
