Bosentan 125 mg Uses, Dosage, Side Effects & Mechanism

Bosentan 125 mg is a vital medication prescribed for managing pulmonary arterial hypertension (PAH), helping improve patients’ quality of life by easing symptoms and enhancing exercise capacity. BOSENTIME 125, a trusted brand by Steris Healthcare, offers an effective bosentan 125 mg tablet that stands out for its quality and patient-focused formulation.

What is Bosentan 125 mg?

Bosentan 125 mg works through its mechanism of action by blocking endothelin receptors in the blood vessels. Endothelin is a substance that causes blood vessels to narrow, increasing blood pressure in the lungs. By blocking these receptors, bosentan helps relax and widen the pulmonary arteries, reducing pressure and improving blood flow. Understanding the bosentan structure reveals why it efficiently targets these receptors, making it an essential option for PAH treatment.

Bosentan Mechanism of Action

Bosentan works by competitively blocking endothelin-1 (ET-1) from binding to endothelin receptors type A (ETA) and type B (ETB) located on vascular smooth muscle cells and endothelial cells in the pulmonary arteries. Endothelin-1 is a potent vasoconstrictor that contributes to narrowing and remodeling of blood vessels, significantly increasing vascular resistance and pressure. By antagonizing these receptors, bosentan prevents ET-1-induced vasoconstriction and cellular proliferation. This leads to dilation of pulmonary blood vessels, decreased pulmonary arterial pressure, and improved blood flow and oxygen delivery to tissues.

Bosentan Structure

Bosentan is a synthetic compound classified as a dual endothelin receptor antagonist. Its chemical structure is composed of a sulfonamide group attached to a biphenyl system with an imidazole ring, which allows it to bind selectively to endothelin receptors ETA and ETB. This selective binding interferes with the endothelin signaling pathway—a key factor in pulmonary arterial constriction and vascular remodeling. The structure facilitates high receptor affinity and antagonist activity, making bosentan effective in reducing pulmonary hypertension.

Bosentan 125 mg Uses

Bosentan 125 mg tablet is primarily used to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs. This can lead to heart strain and reduced oxygen supply to the body. BOSENTIME 125 helps by:

• Improving exercise ability and physical activity tolerance

• Reducing symptoms such as shortness of breath, fatigue, and chest pain

• Slowing down the progression of pulmonary vascular disease

• Treating PAH associated with connective tissue diseases (e.g., scleroderma)

• Managing PAH due to congenital heart defects or idiopathic causes

By addressing these factors, bosentan 125 mg improves patients’ overall quality of life and functional capacity.

Dosage and Administration

• Treatment usually starts with a lower dose (62.5 mg twice daily) for 4 weeks, followed by bosentan 125 mg twice daily as maintenance therapy.

• Take the medicine regularly at the same time each day, with or without food.

• Do not stop the medicine suddenly unless advised by your doctor.
