It contains Tadalafil, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE-5) inhibitors.

Uses of Megalis 20mg

Doctors prescribe Megalis 20mg for:

  • Treatment of erectile dysfunction

Erectile dysfunction or impotence is a sexual disorder in which a man is unable to attain or maintain erections adequate for sexual intercourse.

This happens when there is reduced blood flow to the male sexual organ.

Decreased blood flow can be due to physical disorders or psychological conditions like depression, anxiety, or stress.

Chronic lifestyle factors such as alcohol consumption, obesity, and smoking can contribute to ED.

  • Treatment of pulmonary arterial hypertension (PAH)

Pulmonary arterial hypertension is caused by the thickening of the walls of your arteries, which supply your lungs, causing trouble for blood to get through.

This disorder can also cause shortness of breath, dizziness, tiredness, swelling in ankles & legs, and chest pain.

Macleods Pharmaceuticals Pvt Ltd. is a well-known pharma company that manufactures Megalis.

How does Megalis 20mg work?

Megalis 20mg is a phosphodiesterase (PDE-5) inhibitor.

To treat erectile dysfunction, Tadalafil increases blood flow to the male reproductive organ by relaxing muscles present in penile blood vessels.

For treatment of PAH, it relaxes or widens blood vessels present inside your lungs.

When blood vessels relax or widen, the heart can easily pump blood through the lungs, reducing blood pressure in the lungs.
