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.
