Question

Define opioid drugs with an example.

Hint:

Opioids are pain-relieving drugs that act on the nervous system; an example is morphine.

Answer 1

Opioid drugs are a class of substances that act on opioid receptors in the brain and nervous system to produce analgesic (pain-relieving) effects. They mimic the action of endorphins, which are natural chemicals in the body that reduce pain and promote feelings of well-being. While opioids are highly effective for pain management, they also carry a high risk of addiction, dependence, and overdose due to their psychoactive properties. Opioid drugs are a class of pain-relieving medications that act on the nervous system to relieve pain by binding to opioid receptors. 

Example: Morphine is a commonly used opioid drug to manage severe pain in patients.
