How Viagra Works

Viagra works by increasing blood flow to the penis, helping achieve and maintain an erection when sexually stimulated. It achieves this by inhibiting an enzyme known as phosphodiesterase type 5 (PDE5) that regulates blood flow in the penis. With PDE5 inhibited, the levels of another molecule called cyclic guanosine monophosphate (cGMP) increase, leading to vasodilation and enhanced blood flow.
