Product description
Drug Name
Minipress (Prazosin)
Pharmacological action
Peripheral vasodilator. It is a blocker of postsynaptic α1-adrenoreceptors, prevents the vasoconstrictor effect of catecholamines. Reduces BP by decreasing RAS, reduces post-load on the heart. Dilates peripheral veins, also reducing the preload on the heart. Improves systemic and intracardiac hemodynamics in patients with chronic heart failure. Reduces the pressure in the small circle of the circulation. Vasodilator effect of prazosin is accompanied with moderately pronounced reflex tachycardia. When prescribed for a long time it reduces the concentration of atherogenic lipids in blood.
Reduces myocardial oxygen demand, increases blood stroke volume during exercise. Reduces renal vascular resistance.
Reduces resistance and pressure in the urinary tract (due to relaxation of the smooth muscles of the bladder neck, prostate gland and its capsule), which leads to a decrease in the severity of symptoms of urinary tract dysfunction.
