Mechanism of Action
Sildenafil citrate inhibits PDE5 (phosphodiesterase type 5), an enzyme that restricts blood flow to penile tissue. Blocking PDE5 allows cyclic guanosine monophosphate (cGMP) to build up, relaxing smooth muscle. Blood vessels are widened by this, which improves blood flow during sexual stimulation.
Clinical Uses
- Used to treat erectile dysfunction (ED) in adult men
- Used to treat pulmonary arterial hypertension (high blood pressure in the blood vessels of the lungs)
