Low-dose and very low-dose spironolactone in combination therapy for essential hypertension: evaluation by self-measurement of blood pressure at home.

Low-dose (25 mg) or very low-dose (12.5 mg) spironolactone were added among 86 uncontrolled hypertensive patients who were undergoing monotherapy with calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors (ACEIs), or angiotensin AT1-receptor blockers (ARBs). Morning home systolic/diastolic blood pressure (BP) reduction was similar among the CCB (n = 30, -8.

Blood pressure-lowering effect and duration of action of bedtime administration of doxazosin determined by home blood pressure measurement.

The effects and duration of action of bedtime administration of doxazosin 2 mg for 4 weeks on uncontrolled morning home hypertension were investigated. Morning home blood pressure (HBP) was significantly lowered by bedtime administration of doxazosin. Doxazosin significantly lowered evening HBP only in the subgroup of patients with an uncontrolled evening HBP.
