Question 5 of 5
All of the following are naturally occurring opium alkaloids EXCEPT:
Correct Answer: C
Rationale: Opium alkaloids are naturally derived from the opium poppy (Papaver somniferum). Morphine, the principal alkaloid, is a potent mu receptor agonist used for severe pain. Codeine, milder, acts as an analgesic and antitussive, also poppy-derived. Papaverine, a smooth muscle relaxant, is another natural alkaloid from opium, though less opioid-like. Meperidine (choice C) is a synthetic opioid, chemically distinct (a phenylpiperidine), developed as a pharmaceutical alternative for pain management, not extracted from opium. It mimics natural opioids via receptor agonism but isn't naturally occurring. This differentiation is essential in pharmacology to classify drugs by origin, impacting their regulation, synthesis, and clinical understanding. The question tests knowledge of natural versus synthetic opioids, crucial for historical context and therapeutic application.
