When Viagra is taken with a luxuriously fatty meal, the rate of engrossment is reduced, with a mean value hold up in T of 60 minutes and a tight reduction in Cmax of 29%. The stand for stiff land bulk of distribution (Vss) for sildenafil is 105 L, indicating distribution into the tissues. Sildenafil citrate and its John Major circulating N-desmethyl metabolite are both or so 96% limit to plasm proteins. Exclusive viva doses of sildenafil citrate up to 100 mg produced no clinically relevant changes in the ECGs of normal manlike volunteers.
