1. What is Ambrisentan Kern Pharma and what is it used for

This medicine contains the active substance ambrisentan. It belongs to a group of medicines called other antihypertensives (used to treat high blood pressure).

It is indicated for the treatment of pulmonary arterial hypertension (PAH) in adults, adolescents, and children from 8 years of age and older. PAH consists of high blood pressure in the blood vessels (the pulmonary arteries) that carry blood from the heart to the lungs. In people with PAH, these arteries become narrower, so the heart has to work harder to pump blood to the lungs. This makes people feel tired, dizzy, and have difficulty breathing.

Ambrisentan widens the pulmonary arteries, making it easier for the heart to pump blood through them. This reduces blood pressure and alleviates symptoms.

Ambrisentan may also be used in combination with other medicines used to treat PAH.
