Opsutan 10mg (Macitentan)

Introduction

Opsutan 10mg is a prescription medicine used for the treatment of pulmonary arterial hypertension (PAH), a condition where blood pressure becomes abnormally high in the arteries of the lungs. It contains Macitentan, which helps relax blood vessels in the lungs and improves blood flow, making it easier for the heart to pump blood.

This medication is generally used for long-term management to improve breathing ability, reduce symptoms like fatigue and shortness of breath, and slow disease progression.

What is Opsutan 10mg?

Opsutan 10mg is an endothelin receptor antagonist (ERA). It blocks a natural substance called endothelin, which causes narrowing of blood vessels.

Key Details

• Active Ingredient: Macitentan 10mg
• Drug Class: Endothelin receptor antagonist
• Form: Oral tablet
• Prescription: Yes
• Primary Use: Pulmonary arterial hypertension (PAH)

Uses of Opsutan 10mg

1. Pulmonary Arterial Hypertension (PAH)

Opsutan is mainly used to treat PAH, where lung arteries become narrowed and pressure increases. It helps improve exercise capacity and quality of life.

2. Slowing Disease Progression

It helps delay worsening of PAH by reducing strain on the heart and lungs.

3. Symptom Relief

Improves symptoms such as:

• Shortness of breath
• Fatigue
• Dizziness

How Opsutan 10mg Works

Opsutan works by blocking endothelin receptors, preventing blood vessel constriction.

• Relaxation of pulmonary arteries
• Improved blood flow in lungs
• Reduced pressure in lung circulation
• Less workload on the heart

This helps improve oxygen supply and overall physical endurance.
