MACITENTAN

About

MACITENTAN belongs to the class of 'anti-hypertensive drugs', primarily used to treat high blood pressure in the lungs' arteries (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 blood to the whole body. Pulmonary hypertension affects arteries in the lungs and the right side of the heart.

MACITENTAN contains 'macitentan', which works by inhibiting the action of Endothelin, a natural substance that constricts blood vessels and raises blood pressure. MACITENTAN widens the constricted pulmonary arteries (blood vessels that carry blood from the heart to the lungs) and increases blood supply, thus lowering blood pressure.

Take MACITENTAN as prescribed by your doctor. Your dose and duration of MACITENTAN will be advised by your doctor, depending upon your medical condition. In some cases, you may experience headaches, inflammation of the airways, and oedema. Most of these side effects of MACITENTAN do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor.

Please inform your doctor if you are using any prescription, or non-prescription drugs, including vitamins and herbal products. Before starting MACITENTAN, let your doctor know if you have allergic reactions to MACITENTAN or other medicines. Inform your doctor if you have low blood pressure, lung, heart, kidney, 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 MACITENTAN without consulting your doctor since it may worsen your condition and increase the risk of future heart problems. Do not consume alcohol with MACITENTAN as it may increase the risk of low blood pressure.

Uses of MACITENTAN

Pulmonary arterial hypertension (PAH) in adults.

Medicinal Benefits

MACITENTAN is an anti-hypertensive medicine that treats high blood pressure in the lungs' arteries (pulmonary arterial hypertension (PAH)). It contains 'Macitentan,' which 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. MACITENTAN widens these constricted arteries and makes it easier for the heart to pump blood, thus lowering the blood pressure.

Directions for Use

Swallow it as a whole with water; do not crush, break or chew it.

Storage

Store in a cool and dry place away from sunlight

Side Effects of MACITENTAN

  • Anaemia (low number of red blood cells) or reduced haemoglobin
  • Headache
  • Bronchitis (inflammation of the airways)
  • Nasopharyngitis (inflammation of the throat and nasal passages)
  • Oedema (swelling), especially of the ankles and feet

In-Depth Precautions and Warning

Drug Warnings

Please inform your doctor beforehand if you are allergic to MACITENTAN or other medicines. Brief your medical history if you have heart failure, liver or kidney diseases, lung conditions (pulmonary fibrosis), anaemia, oedema (fluid retention) and hypotension (low blood pressure) before starting MACITENTAN. MACITENTAN is contraindicated during pregnancy since it harms the foetus. Please get a pregnancy test done before starting MACITENTAN. You should get a negative pregnancy test for sure before using MACITENTAN. Also, please use reliable forms of birth control if you are undergoing treatment with MACITENTAN to avoid pregnancy. Consult your doctor before using MACITENTAN if you are a breastfeeding mother. Complete the course strictly as the doctor advises, even if you feel better, to avoid the recurrence of the disease. Do not drive or operate machinery since MACITENTAN may cause side effects like dizziness and weakness, affecting your ability to concentrate and drive. Avoid consumption of alcohol with MACITENTAN as it may increase the risk of low blood pressure. MACITENTAN is not recommended in patients younger than 18 years of age.

    Patients Concern

    Disease/Condition Glossary

    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. It's a serious condition that can harm the heart's right side. The walls of the pulmonary arteries thicken and stiffen, making it difficult for blood to flow through. Because of the reduced blood flow, the right side of the heart has a harder time pumping blood through the arteries which may lead to heart failure. The common symptoms of pulmonary hypertension are shortness of breath, dizziness, palpitations, and chest pressure. It can affect people of all ages, but it is more common in people who already have a heart or lung problem.

    FAQs

    MACITENTAN consists of Macitentan. It is an anti-hypertensive medicine that lowers blood pressure by widening the pulmonary arteries and making the heart pump blood efficiently.

    No, it is a prescribed drug given by a physician for treating specific medical conditions. Taking it on your own can cause unwanted side effects.

    Even if you feel good, do not stop using the $ name. It should be used as prescribed by your doctor to prevent the recurrence of symptoms and worsening of the disease.

    MACITENTAN should be used with caution in cases of any allergic reactions, heart failure, liver, kidney diseases, lung conditions (pulmonary fibrosis), anaemia, oedema (fluid retention), and hypotension (low blood pressure).

    Shortness of breath, weariness (tiredness), feeling faint or dizzy, chest discomfort (angina), a rapid heartbeat (palpitations), and swelling (oedema) in the legs, ankles, feet, or tummy are all common symptoms of pulmonary hypertension (abdomen).

    Although pulmonary hypertension cannot be cured, there are treatments that can help you control your symptoms and manage your condition. It may be possible to prevent irreversible damage to your pulmonary arteries (which are the blood vessels that supply your lungs) if the cause is detected and treated early.
