Which term describes a pain relieving drug?

  1. Encephalic

  2. Emetic

  3. Iatrogenic

  4. Analgesic

The correct answer is: Analgesic

The term that describes a pain-relieving drug is "analgesic." Analgesics are medications specifically designed to alleviate pain without causing a loss of consciousness. They work by acting on various pain pathways in the body, making them essential in both acute and chronic pain management. Common examples include nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and acetaminophen. In contrast, "encephalic" refers to anything relating to the brain but does not imply any pain-relieving qualities. "Emetic" is a term that describes a drug that induces vomiting, which is not related to pain relief. "Iatrogenic" refers to an adverse condition caused by medical treatment or intervention, which also does not pertain to pain relief. Thus, "analgesic" is the most appropriate choice when discussing medications that provide relief from pain.
