3. Endocrine: Hyper/hypoglycemia, unstable DM.
4. Gastrointestinal: Dry mouth uncommon but maybe.
Changes in GI motility: anorexia, n/v, flatulence,
constipation.
5. GU: Impotence or decreased libido.
6. Resp: Bronchospasm and dyspnea. Nasal stuffiness.
7. Less common: muscle and joint pain, rashes, facial swelling.

Pilocarpine: oral form: salivary gland secretion
treatment for xerostomia from radiation.
Bethanechol: increases tone of detrusor urinae
muscle: produces contractions strong enough to
initiate micturation and empty the bladder.
Stimulates gastric motility as well, increasing gastric
tone and restoring rhythmic peristalsis.
