It is also used to treat pulmonary arterial hypertension (PAH) by relaxing blood vessels in the lungs, improving blood circulation, and reducing strain on the heart. Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class of drugs and should be taken under medical supervision.

How Sildenafil works

  • In patients with pulmonary hypertension, Sildenafil relaxes blood vessels in the chest, thereby increasing the blood supply to the lungs and reducing the heart’s workload.
