Final answer:
Idiopathic pulmonary hypertension is managed through lifestyle modifications and medications like calcium channel blockers, ACE inhibitors, ARBs, and thiazide-diuretics. A step-care approach may be used to achieve targeted blood pressure levels.
Step-by-step explanation:
The question refers to the treatment (Tx) of idiopathic pulmonary hypertension (HTN), a type of high blood pressure that affects the arteries in the lungs and the right side of the heart. In treating pulmonary hypertension, the goal is to manage symptoms and slow the progression of the disease. Lifestyle changes such as a healthier diet and reducing salt intake can be beneficial in managing hypertension. Often, these measures need to be supplemented with medications.
To treat pulmonary hypertension, several classes of antihypertensive medications may be used, including calcium channel blockers, angiotensin converting enzyme inhibitors (ACE inhibitors), angiotensin receptor blockers (ARBs), and thiazide-diuretics. Drugs that block the production of angiotensin II, such as ACE inhibitors, can also be effective. A step-care approach is often implemented when target blood pressure levels are not achieved with initial treatments. This can include the use of multiple medications in combination to optimize efficacy.
