Cenforce 50 mg works by enhancing blood flow to the penis, aiding men in achieving and maintaining an erection during sexual activity. Its active ingredient, sildenafil citrate, is a phosphodiesterase type 5 (PDE-5) inhibitor. When sexually stimulated, the inhibition of PDE-5 leads to the relaxation of blood vessels and smooth muscles in the penis. This relaxation allows increased blood flow, resulting in an erection. Cenforce 50 mg is effective only with sexual stimulation and is used to treat erectile dysfunction (ED) in men, helping them improve their sexual performance and confidence.
