Enhanced endogenous epinephrine release from the vascular adrenergic neurons in spontaneously hypertensive rats.

abstract：:In a randomized double-blind, placebo-controlled, crossover study of isradipine (5 mg twice daily), effects on peripheral hemodynamic reflex responses were studied in nine patients (mean age 48 years) at baseline and after six weeks of active treatment. Assessments included vital signs, resting blood flow in the calf ...
