Standardised effects on roue press were celebrated with 25 mg, 50 mg, and 100 mg doses of sildenafil, therefore the personal effects are non akin to window pane or plasm levels inside this dose grade. Bigger effects were recorded among patients receiving incidental nitrates [see Contraindications (4)].

In healthy volunteers, plasma concentrations of this metabolite are about 40% of those seen for sildenafil, so that the metabolite accounts for close to 20% of sildenafil’s pharmacological personal effects. In patients with PAH, however, the ratio of the metabolite to sildenafil is higher. Both sildenafil and the fighting metabolite give terminus half-lives of astir 4 hours.
