Randomized Controlled TrialEfficacy and safety of PDE-5 inhibitor tadalafil in pulmonary arterial hypertension.
Pulmonary arterial hypertension (PAH) is a life threatening disease for which phosphodiesterase-5 inhibitor sildenafil is recently approved. We aimed to evaluate the efficacy and safety of tadalafil, a long acting congener of sildenafil, in treatment of PAH related to previous left to right shunt lesions. ⋯ Tadalafil, in patients with PAH related to previous congenital left to right shunt lesions, lead to a significant improvement in exercise capacity (6MWD), PASP and WHO Class with reduced perceived exertion and was well tolerated.
