When sexual stimulation occurs, nitric oxide is released, selling the conversion of guanosine triphosphate (GTP) to cGMP. Increased cGMP relaxes clean muscle and dilates blood vessels, resulting in enhanced blood flow into the penis and resulting in an erection.

Caution is advised when considering ED medications in patients who've pre-existing cardiovascular situations, significantly these requiring nitrates or who've a historical past of myocardial infarction or unstable angina. Using PDE5 inhibitors alongside nitrates can lead to severe hypotension, doubtlessly resulting in life-threatening consequences.

Patients with important liver or renal impairment should use these medications with warning, as their metabolism and clearance may be affected.
