P Force Fort 150 Mg is a medication that contains sildenafil citrate, an active ingredient used primarily to treat erectile dysfunction (ED) in men. Sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow to the penis. By blocking PDE5, sildenafil citrate increases blood flow to the penis during sexual stimulation, allowing for an erection to occur and be maintained.
