Treatment Summary
Sildenafil is a medication used to treat erectile dysfunction, pulmonary arterial hypertension, and chest pain. It works by preventing the breakdown of a chemical called cyclic guanosine monophosphate (cGMP), which helps relax the muscles in the penis and lungs and increases blood flow. It was first researched as a potential treatment for chest pain, but was later discovered to be useful in treating erectile dysfunction. It is available under the brand name Viagra and as a generic medication with or without a prescription in some countries.

How Sildenafil Citrate Affects Patients
Sildenafil is a drug that primarily affects the phosphodiesterase-5 enzyme (PDE5) and has been shown to be effective in treating erectile dysfunction. In studies, patients taking the drug experienced improved erections within 60 minutes of taking it. Its effects can last up to 4 hours, though they are weaker after that time. Sildenafil can also cause a mild and temporary decrease in blood pressure, with greater decreases seen in those with cardiovascular disease. It does not affect the heart rhythm, and can even reduce pulmonary systolic blood pressure in those with pulmonary arterial hypertension. Mild and temporary
How Sildenafil Citrate works in the body
Sildenafil is a medication used to treat erectile dysfunction. It works by increasing blood flow to the penis. This is done by activating a chain reaction that starts with sexual stimulation. This stimulation releases nitric oxide, which activates an enzyme called guanylate cyclase. The enzyme then increases levels of cyclic guanosine monophosphate, which causes the blood vessels in the penis to relax and allow more blood to flow in. Sildenafil also helps to reduce pulmonary arterial hypertension by increasing the levels of cyclic guanosine monophosphate in the pulmonary vascular smooth muscle cells, causing them
