The alpha-blocker is
a type of antiadrenergic which is used in the treatment
of overflow incontinence after prostate cancer treatment.
The alpha-blocker binds to the alpha adrenergic receptor
and prevents the constriction of the bladder neck muscles.
Because overflow incontinence is caused by the tightening
of the bladder neck muscles when the urinary bladder
is full and distended, preventing constriction while
inciting relaxation allows the patient to void freely.
