Agents for pulmonary hypertension are drugs that reduce blood pressure in the lungs.
Pulmonary hypertension can occur after severe and recurrent pulmonary thromboembolism, which may be induced while on other medications or it can occur due to cardiopulmonary disease. Pulmonary hypertension usually progresses to increasing breathlessness and right-sided heart failure.
Agents used to treat pulmonary hypertension act by different mechanisms to reduce pulmonary arterial blood pressure.
