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