Sildenafil works by inhibiting the enzyme PDE5, which breaks down cyclic guanosine monophosphate (cGMP). By blocking PDE5, sildenafil helps maintain higher levels of cGMP, leading to relaxation of the smooth muscles in the penis and increased blood flow, which results in an erection when sexually aroused.
