The active ingredient in viagra, sildenafil, is one of the most well-known, and effective, treatments used for erectile dysfunction (impotence).
Viagra has acquired an almost mythical status in recent years, but it is the Sildenafil, the active ingredient, which does the work. Sildenafil is a type of drug known as a phosphodiesterase type 5 inhibitor. These drugs work by preventing the action of a chemical in the body called phosphodiesterase type 5.
The action of sidlenafil is crucial – the phosphodiesterase type 5 works to break down the chemical (Cyclic GMP) that is responsible for widening the blood vessels in the penis and causing an erection.
Thus if you take your medication (viagra or similar) approximately one hour before intended intercourse, you will be able to respond appropriately when you are sexually stimulated.
While we understand how the chemicals work to produce an erection, and thus what drugs can help improve this, what is often harder to pin down is the causes of erectile dysfunction or impotence.
Causes can range from some type of underlying illness through to stress – which is why it is essential to talk to your doctor if you are suffering from these problems.
Often this can be a symptom of an undetected, underlying illness such as diabetes, high blood pressure, or high cholesterol – dealing with an underlying illness such as this can thus often be the quickest way to resolve the problem, as well as being crucial for your overall health.
