Drug Development for Hypertension: Do We Need Another Antihypertensive Agent for Resistant Hypertension?
The prevalence of resistant hypertension is seemingly much lower than had been reported in early studies. Recent analyses suggest that <5 % of treated hypertensive patients remain uncontrolled if fully adherent to an optimized antihypertensive treatment. However, these patients do have increased cardiovascular risk and need effective therapeutic approaches. Drug development is a high-risk, complex, lengthy, and very expensive process. In this article, we discuss the factors that should be considered in the process of developing a new agent for treatment of resistant hypertension.
