drugs which cause urinary retention
PHARMACOLOGIC. Medications with anticholinergic properties, such as tricyclic antidepressants, cause urinary retention by decreasing bladder detrusor muscle contraction. 12 Sympathomimetic drugs (e.g., oral decongestants) cause urinary retention by increasing alpha-adrenergic tone in the prostate and bladder neck.
The most common cause of urinary retention is benign prostatic hyperplasia. Other common causes include prostatitis, cystitis, urethritis, and vulvovaginitis; receiving medications in the anticholinergic and alpha-adrenergic agonist classes; and cortical, spinal, or peripheral nerve lesions.
