Factors that contribute to resistant forms of hypertension. Pharmacological considerations.
Treatment failure may be caused by induction of compensatory mechanisms that compromise effectiveness of the antihypertensive regimen. Antihypertensive agents have been classified according to mechanism of action, and compensatory mechanisms usually evoked by each class of drugs have been reviewed. Host factors may be responsible for the inability to control blood pressure or may predict special sensitivity or contraindication to a particular class of antihypertensive agents. Recommendations have been made for modification of stepped-care regimens and selection of initial antihypertensive agents based on host factors. Experimental evidence suggests the ability to target antihypertensive therapy in a manner that will prevent or reverse specific end-organ damage. Clinical studies are needed to define the long-term benefit derived from aggressive target organ protection.
