Cenforce 150 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, a well-known phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by relaxing blood vessels and increasing blood flow to the penis during sexual arousal, which helps achieve and maintain an erection. The 150 mg strength is a higher dose compared to the commonly prescribed 50 mg or 100 mg tablets, typically used when lower doses have not been effective.
