AMBRISENTAN
About
AMBRISENTAN is used to treat high blood pressure in the arteries of the lungs (pulmonary arterial hypertension). Hypertension is a medical condition in which the blood exerts high pressure (force exerted by circulating blood) against the walls of blood vessels. This condition makes the heart work harder in pumping the blood to the whole body. Pulmonary hypertension affects arteries in the lungs and the right side of the heart.
AMBRISENTAN contains ‘Ambrisentan,’ which belongs to the class of ‘endothelin receptor blockers’. Ambrisentan works by inhibiting the action of Endothelin, a natural substance that constricts blood vessels and raises blood pressure. AMBRISENTAN widens the constricted pulmonary arteries (blood vessels that carry blood from the heart to the lungs) and increases blood supply to the lungs, thus lowering the blood pressure.
In some cases, AMBRISENTAN can cause side effects like headache, dizziness, palpitations, breathlessness, runny nose, feeling sick, diarrhoea, and fatigue. These side effects are not familiar to everyone and vary individually. If you notice any side effects that are not manageable, please consult your doctor.
Please inform your doctor if you are using any prescription or non-prescription drugs, including vitamins and herbal products. Let your doctor know if you have any allergic reactions to AMBRISENTAN or any other medicines, before starting AMBRISENTAN. Inform your doctor if you have low blood pressure, lung, heart, kidney or liver problems, and anaemia (lack of blood cells). It is advised to consult a doctor if you are a pregnant or breastfeeding mother. Do not stop taking AMBRISENTAN without consulting your doctor since it may worsen your condition and increase the risk of future heart problems. Do not consume alcohol with AMBRISENTAN as it may increase the risk of low blood pressure.
Uses of AMBRISENTAN
Medicinal Benefits
AMBRISENTAN is an anti-hypertensive medicine that treats high blood pressure in the arteries of the lungs (pulmonary arterial hypertension (PAH)). It contains ‘Ambrisentan,’ an endothelin receptor blocker. AMBRISENTAN works by inhibiting the action of Endothelin, a natural substance that constricts blood vessels and raises blood pressure. In people with PAH, the pulmonary arteries get narrower making the heart work harder to pump blood through them. AMBRISENTAN widens these constricted arteries and makes it easier for the heart to pump blood, thus lowering the blood pressure.

Habit Forming
Diet & Lifestyle Advise
Reduce sodium intake in your diet to maintain your blood pressure.
Eat natural and healthy foods by cutting down on high on sodium processed foods.
Lose those extra pounds, since being obese can be a risk factor for hypertension.
Exercise regularly to maintain good heart health.
Avoid smoking and alcohol intake.
Chronic stress may also cause high blood pressure. Therefore, avoid stress triggers and make time for yourself to relax and do activities that you enjoy.
Try to include heart-healthy omega 3 fatty acids containing food drinks in your daily diet. You can also use low-fat cooking oil like olive oil, soybean oil, canola oil and coconut oil to lower your elevated blood pressure.
Limit sodium chloride intake (table salt) in your daily diet to 2300 mg per day or less than 1500 mg is ideal for most adults.

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 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.
