What Is Minoxidil and How Does It Work?
Minoxidil is indicated only in the treatment of hypertension that is symptomatic or associated with target organ damage and is not manageable with maximum therapeutic doses of a diuretic plus two other antihypertensive drugs. At present use in milder degrees of hypertension is not recommended because the benefit-risk relationship in such patients has not been defined.
Minoxidil is available under the following different brand names: Loniten, Minodyl, and Minoxidil HTN.
