Uses of Macitent Tablet

Benefits of Macitent Tablet

Pulmonary arterial hypertension (PAH)
Pulmonary arterial hypertension (PAH) is a condition where the blood pressure in the arteries of the lungs becomes abnormally high, making it harder for the heart to pump blood through them.

This helps ease symptoms such as shortness of breath and fatigue, supports better exercise capacity, and slows disease progression.
