Charlie is a 65-year-old male who has been diagnosed with
hypertension and benign prostatic hyperplasia. Doxazosin has been

1. Increases peripheral vasoconstriction
2. Decreases detrusor muscle contractility
3. Lowers supine blood pressure more than standing pressure
4. Relaxes smooth muscle in the bladder neck - answer Relaxes
smooth muscle in the bladder neck
To reduce potential adverse effects, patients taking a peripherally
acting alpha1 antagonist should do all of the following EXCEPT:

3. Monitor their blood pressure and skip a dose if the pressure is
less than 120/80
4. Weigh daily and report weight gain of greater than 2 pounds in
one day - answer 3. Monitor their bp and skip a dose if the pressure
is less than 120/80

by decreasing HR and vascular resistance
