Viagra is part of a group of drugs known as phosphodiesterase-5 inhibitors.japan tengsu These drugs work by blocking the action of a protein in the body called phosphodiesterase-type 5 (PDE-5). This protein is responsible for breaking down cyclic guanosine monophosphate (cGMP), a molecule that triggers erections by increasing blood flow to the penis.

When PDE-5 is blocked, cGMP is not broken down and the blood vessels are allowed to widen, increasing blood flow to the penis and facilitating an erection. This makes Viagra an effective treatment for ED.

However, Viagra should be used with caution. Certain medications can cause unwanted or dangerous effects when used with Viagra. For instance, it should not be taken with nitrate drugs used for chest pain or heart problems. Combining Viagra with these medications can cause a sudden and serious decrease in blood pressure.

Furthermore, Viagra should not be used by individuals who have been advised against sexual intercourse for health reasons, or those with certain pre-existing conditions such as heart disease, high or low blood pressure, liver or kidney disease, a blood cell disorder, a bleeding disorder, stomach ulcers, or physical deformities of the penis.

In conclusion, Viagra is a powerful medication for treating ED and pulmonary arterial hypertension. However, it should be used responsibly and under the guidance of a healthcare professional due to potential interactions and contraindications.
