Sildenafil is a medication used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It’s a PDE5 inhibitor, which means it improves blood flow to help men get erections and to lower blood pressure in the lungs.
You’ll most often find sildenafil in tablet form (Viagra), but it’s also available as a compounded troche, which dissolves in your mouth.
