Mechanism of action
It selectively blocks post-synaptic alpha1 adrenergic receptor due to which vasodilatation occurs. The haemodynamic effects are decreased arterial pressure, reduction in venous and arterial tone.
DOXAZOSIN treats high blood pressure. It may also be used to treat symptoms of an enlarged prostate (benign prostatic hyperplasia). It works by relaxing blood vessels, which decreases the amount of work the heart has to do.
