Abstract

The invention provides an ambrisentan tablet and a preparation method thereof. The ambrisentan tablet consists of ambrisentan and pharmaceutically acceptable adjuvant materials. The ambrisentan tablet disclosed by the invention can be used for effectively treating pulmonary hypertension; and the ambrisentan tablet is simple in preparation process, good in dissolution degree, low in content of related materials, good in quality and stable and controllable in quality.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to an ambrisentan tablet and a preparation method thereof. Background technique [0002] Pulmonary hypertension refers to the persistent increase of pulmonary artery pressure caused by various reasons. It is a rare chronic syndrome, manifested as pulmonary artery narrowing, damage and high blood pressure. Thickening and damage to the walls of the pulmonary artery can cause the blood vessel to narrow, and small blood clots can form in the vessel, eventually leading to blockage. Because the right myocardium is not as strong as the left myocardium and is more susceptible to damage, the increase in vascular resistance will increase the workload of the right heart, eventually leading to right heart failure and death. Right heart failure is the only common cause of disability and death for all types of pulmonary hypertension patients, and pulmonary hypertension is also the most importan...
