What is Sildenafil 100 mg, and how does it Treat Erectile Dysfunction?

Sildenafil is a generic version of brand-name Viagra, which comes under the drug class known as phosphodiesterase-5 (PDE5) inhibitors. It is a first-line treatment for a condition known as erectile dysfunction in males. As a secondary treatment, this medication may also be used for pulmonary arterial hypertension. This medication may also be prescribed for conditions not stated here.

Erectile dysfunction is a common sexual problem in males that is characterized by the inability to achieve or maintain an erection. On the other hand, pulmonary arterial hypertension is a condition characterized by high B.P (blood pressure) in the blood vessels that carry/transport blood from the heart to the lungs.

Mechanism of Action :

This medication begins its mechanism by blocking an enzyme called PDE5, which, as a result, soothes certain blood vessels. In order to treat ED, it functions to facilitate blood flow to the penis upon sexual stimulation. On the other hand, in order to treat pulmonary arterial hypertension, it functions by relaxing the blood vessels in the lungs, which in turn diminishes the increased blood pressure and reduces the heart’s workload. 

Available Strengths:

This medication is available in many forms, ranging from 20mg to 100mg. However, it is recommended that you consult your doctor to determine the right strength. The medical professional will consider your medical history and present health status to select the appropriate dosage.

Effects Duration:

It starts working within 30 minutes after the last dosage, and the effects may last up to 5 hours in the body. Several factors may influence its impact on the body, including other medications, dosage, and overall health.
