The titration research, in which most patients received 100 mg, showed comparable results.
Figure 6 exhibits that regardless of the baseline levels of operate, subsequent operate in sufferers treated with VIAGRA was better than that seen in patients treated with placebo. At the identical time, on-therapy function was better in treated sufferers who were much less impaired at baseline. VIAGRA is rapidly absorbed after oral administration, with a mean absolute bioavailability of 41% (vary 2563%). The pharmacokinetics of sildenafil are dose-proportional over the beneficial dose range.
Sildenafil at recommended doses has no effect within the absence of sexual stimulation. Safety of mixed use of PDE5 inhibitors and alpha-blockers could also be affected by other variables, together with intravascular volume depletion and other anti-hypertensive medicine.
