Uses of Ambrisentan
• Treatment of Pulmonary Arterial Hypertension: Ambrisentan is used to treat Pulmonary Arterial Hypertension (PAH) by increasing blood supply to the lungs, thus lowering the blood pressure.

Medicinal Benefits
Ambrisentan offers several important benefits that help improve exercise capacity, reduce symptoms, and slow the progression of pulmonary arterial hypertension:
- Improved Exercise Capacity: By widening the blood vessels in the lungs, Ambrisentan reduces the workload on the heart, making activities such as walking, climbing stairs, and household tasks easier.

- Slows Disease Progression: Regular use helps delay the worsening of pulmonary arterial hypertension, reducing the risk of complications and hospitalisation.
- Protects Heart Function: Lowering pressure within the pulmonary arteries reduces strain on the right side of the heart, supporting better long-term cardiovascular health.

Patients Concern
Disease/Condition Glossary
Hypertension: It is a medical condition in which blood pressure is elevated persistently in the arteries. It is considered an essential risk factor for cardiovascular diseases and can be caused by obesity, diabetes, smoking, high salt intake, stress, lack of physical activity or ageing. Blood pressure is measured in the ratio of systolic pressure to diastolic pressure. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg and the diastolic pressure is 90 mm of Hg. The ideal blood pressure range lies between 90/60 mmHg and 120/80 mmHg. If the blood pressure is 140/90 mmHg or greater, it is considered high blood pressure.
Pulmonary Arterial Hypertension: It is referred to as high blood pressure in the blood vessels (the pulmonary arteries) that carry blood from the heart to the lungs. Symptoms include shortness of breath, dizziness, and chest pressure.
