Currently, the most important alpha-blockers used in treating hypertension are prazosin and its long-acting congeners, doxazosin and terazosin. Although there are minor age-related changes in the pharmacokinetics of these compounds, they result in no appreciable alteration in dose requirements. Overall, published evidence does not indicate any loss of responsiveness to alpha-blockade in the elderly. Despite the potential risks of first-dose hypotension and of postural hypotension, long-acting alpha-blockers may warrant further consideration as possible first-line therapy in elderly hypertensive patients. These agents allow the simplicity of once-daily dosing, and their cardiac and metabolic effects offer potential advantages.
