Rationale 1: Excreting more urine is an effect of diuretic medications.
Rationale 2: Increasing the efficiency of the heart is not an effect of doxazosin (Cardura).
Rationale 3: Doxazosin (Cardura) is selective for blocking alpha1-receptors in vascular smooth muscle, which results in dilation of arteries and veins.
Rationale 4: Decreasing the release of stress hormones is not an effect of doxazosin (Cardura).
