P Force Fort 150 mg is a medication containing sildenafil citrate, the same active ingredient found in Viagra. It is primarily used to treat erectile dysfunction (ED) in men. Similar to other sildenafil-based medications, P Force Fort 150 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for regulating blood flow in the penis. By inhibiting PDE5, this medication helps to relax the blood vessels in the penis, allowing for increased blood flow when sexually aroused. This improved blood flow can then lead to an erection.
