In a randomized, double-blind, multi-center, placebo-managed, parallel-group, dose-ranging study, 234 patients with PAH, aged 1 to 17 years, physique weight better than or equal to 8 kg, were randomized, on the basis of physique weight, to 3 dose levels of sildenafil citrate, or placebo, for sixteen weeks of treatment. viagra website had mild to moderate signs at baseline: WHO Functional Class I (32%), II (51%), III (15%), or IV (0.4%). viagra directions -third of patients had primary PAH; two-thirds had secondary PAH (systemic-to-pulmonary shunt in 37%; surgical repair in 30%).

The outcomes suggest an approximately 2-fold improve in the danger of NAION inside 5 half-lives of PDE5 inhibitor use.
