Sildenafil citrate, the active component of the medicine Cenforce 100 mg, is frequently used to treat erectile dysfunction (ED) in men. The inability to obtain or sustain a solid erection during sexual engagement is the hallmark of erectile dysfunction. The group of medications known as phosphodiesterase type 5 (PDE5) inhibitors includes sildenafil citrate. Cenforce 100 Australia functions by preventing the PDE5 enzyme from breaking down cyclic guanosine monophosphate (cGMP). Sildenafil helps to get and maintain an erection by allowing cGMP to build up and improving blood flow to the penis through the inhibition of PDE5.
