ABSTRACT
Introduction
According to current guidelines, malignant hypertension is one of the emergencies in hypertension. The definition requires the presence of bilateral retinal hemorrhages or exudates, with or without papilledema, acute heart failure and acute deterioration in renal function in severe hypertension. Patients with malignant hypertension are characterized by pronounced target organ damage, including structural and functional cardiac abnormalities and renal insufficiency.
Areas covered
Knowledge of the available treatment options is extremely important as we know that we only have a limited time to reduce blood pressure. There are only four drugs dedicated to immediate blood pressure lowering in patients with malignant hypertension, including ‘first-line’ and alternative drugs. Our review aims to discuss all those drugs and gives practical suggestions on how to properly use them.
Expert commentary
The decision of which drug to use depends on numerous factors including the clinical indications, pharmacokinetics, toxicity and drug interactions. Furthermore, frequently, more than one of the recommended drugs is required for the successful lowering of the patient’s blood pressure.
Article highlights
In malignant hypertension, there is only a limited time to reduce blood pressure
Drugs dedicated to immediate BP lowering can be divided into first-line (Labetalol and Nicardipine) and alternative (Nitroprusside and Urapidil)
Various studies have been conducted over new drugs using animal models: examples include fenofibrate and the 20-HETE receptor antagonist (AAA) with new mechanisms of action
Combination therapy seems to be crucial in effective blood pressure lowering
There is a general lack of studies on the treatment of malignant hypertension due to its rare prevalence and sudden characterization
