CLINICAL PHARMACOLOGY
PHARMACODYNAMICS
A. Benign Prostatic Hyperplasia (BPH)
The symptoms associated with BPH are related to bladder outlet
obstruction, which is comprised of
two underlying components: a static component and a dynamic component.
The static component is a
consequence of an increase in prostate size. Over time, the prostate
will continue to enlarge. However,
clinical studies have demonstrated that the size of the prostate does
not correlate with the severity of
BPH symptoms or the degree of urinary obstruction. The dynamic
component is a function of an
increase in smooth muscle tone in the prostate and bladder neck,
leading to constriction of the bladder
outlet. Smooth muscle tone is mediated by sympathetic nervous
stimulation of alpha-1 adrenoceptors,
which are abundant in the prostate, prostatic capsule and bladder
neck. Th
