Sildenafil Citrate, the active ingredient in Sildisoft tablets, belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. By blocking PDE5, Sildenafil Citrate promotes the relaxation of smooth muscles in the blood vessels of the penis, allowing for increased blood flow when a man is sexually stimulated. This helps to facilitate erections and improve erectile function.
