Which one of the following drugs increases gastrointestinal motility?
1) Glycopyrrolate.
2) Atropine.
3) Neostigmine.
4) Fentanyl.
Pharmacology Answer: 3
Synthetic opioids, sharing properties of opium and morphine, include meperidine, propoxyphene, diphenoxylate, fentanyl, buprenorphine, methadone, and pentazocine. Various opiate effects are analgesia, respiratory depression, constipation, and euphoria.
Fentanyl (80 to 100 times more powerful than morphine) is especially dangerous.
Atropine blocks the muscarinic receptors. Atropine decreases gastrointestinal tract motility and secretion and causes constipation.
Although various derivatives and congeners of atropine (such as propantheline, isopropamide, and glycopyrrolate) have been advocated in patients with peptic ulcer or with diarrheal syndromes
Neostigmine is Cholinesterase inhibitors that enhance the effects of parasympathetic stimulation and leads to reversal of intoxication by agents with a anticholinergic action
