Sildenafil is a medication used in the treatment of erectile dysfunction in men with sexual arousal problems. Its mechanism of action centers on the improving of blood flow to the genital area during sexual arousal.
Sildenafil belongs to a class of medications called Phosphodiesterase (PDE) inhibitors. It is mainly used to treat erectile dysfunction by increasing the blood flow to the penis during sexual stimulation. It has also been proven effective in enhancing the exercise capacity in adults with Pulmonary Arterial Hypertension (PAH), by relaxing the blood vessels in the lungs and allowing blood to flow easily.
