What is bosentan monohydrate used for?
Bosentan is prescribed for adults and children aged three and above to manage arterial hypertension (PAH), a condition characterized by high blood pressure in the blood vessels supplying the lungs. It is believed that Bosentan can enhance exercise capacity and help alleviate the progression of symptoms in individuals with PAH.
What is the mechanism of action of bosentan monohydrate?
Bosentan is part of a group of medications called endothelin receptor antagonists (ERAs). Individuals with arterial hypertension (PAH), exhibit higher levels of endothelin, a powerful blood vessel constrictor, in their bloodstream and lung tissue. Bosentan works by preventing endothelin from attaching to its receptors thus counteracting the impacts of endothelin.
What is the role of bosentan?
The primary choice for treating artery hypertension initially involves using an endothelin 1 antagonist, like bosentan. Bosentan is a medication utilized to manage and treat artery hypertension.
What are the side effects of bosentan?
Blurred vision.
How long is the bosentan treatment?
The treatment plan involved taking 62.5 mg of bosentan twice a day for 4 weeks, followed by an increase to 125 mg orally twice daily for up to 12 weeks, and in certain cases, the duration was extended to 28 weeks for some patients.
Is bosentan effective?
Bosentan works as a blocker for the endothelin A and endothelin B receptors proving its effectiveness in treating arterial hypertension. It has been widely used for this purpose with studies demonstrating enhancements in exercise capacity reduction, in dyspnea and prolonged time before clinical deterioration occurs.
