What Biochemistry Is - And What it is Not

Viagra (generic name: Sildenafil) is an FDA approved prescription drug used to treat male impotence (also known as erectile dysfunction/ED). Both these medication inhibit the body's enzyme dubbed as phosphodiesterase-5 (PDE5) which eliminates cyclic guanosine monophosphate (cGMP), an element which is responsible for blood supply in the male organ. Always consult a physician before taking this or any prescribed medication.
