What is Viagra

Viagra is a brand name for sildenafil.

Today Viagra can also be used by women though some doctors do not prescribe it to women. It is important to know all important information about Viagra before you begin its medication. This is a drug that can lead to very serious health conditions when it is overused thus, it is very necessary to strictly follow your doctor’s advice while under Viagra medication.

You should not use Viagra when you are under nitrate treatments such as treatment for chest pains. This is because combining Viagra with nitrates can seriously lower the patient’s blood pressure which is very risky for one's health. This can also cause heart attack, stroke, and fainting among others. When you experience nausea, become dizzy, tingling in your neck region, tingling in your chest or when you experience any uncomfortable pain while having sex, you should stop immediately and call your doctor as it can be due to a serious side effect of Viagra.

Know More about Viagra

Viagra is a very popular brand of erectile dysfunction medication that helps men gain and sustain an erection for a longer duration. The generic name of this drug is Sildenafil. It mainly works by preventing the action of a certain enzyme called cGMP- specific Phosphodiesterase type-5 (PDE-5). The enzyme helps by breaking down cGMP, which is responsible for helping the smooth muscles relax. When PDE-5 is blocked, the amount of cGMP is increased which promotes vasodilation (a condition that widens the blood vessels) and muscle relaxation.

PDE-5 is found in high quantities in the lungs, retina and the penis. It is also available all over the body where there are smooth muscle cells such as muscles and blood vessels. Viagra is a part of the class of medications called PDE-5 inhibitors.
