Cenforce 50 is a medication used in the treatment of erectile dysfunction (ED) in men. It contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Cenforce 50 contains sildenafil citrate, which works by inhibiting the enzyme PDE5 in the erectile tissue of the penis. This inhibition allows for increased blood flow, which helps in achieving and maintaining an erection during sexual stimulation. Cenforce 50 is usually taken about 30 minutes to 1 hour before anticipated sexual activity. It should be taken on an empty stomach for optimal absorption, although it can be taken with food if needed.
