Fentanyl patches are an example of which type of medication?

• A. Non-steroidal anti-inflammatory drug
• B. Antidepressant
• C. Antipsychotic
• D. Opioid analgesic

Answer: (D)

Fentanyl patches are an opioid analgesic. Fentanyl is a potent synthetic opioid that binds to mu receptors to produce analgesia. The patch form provides a steady release of the drug through the skin over several days, giving continuous pain relief for chronic or severe pain that requires around-the-clock management. This mechanism and route of administration distinguish it from other drug classes: non-steroidal anti-inflammatory drugs reduce pain mainly by inflammation-related mechanisms and COX inhibition, antidepressants modulate mood and pain through different neurotransmitters, and antipsychotics act on dopamine and other receptors for psychiatric conditions. The key point is that fentanyl’s analgesic effect comes from opioid receptor activation, delivered transdermally for sustained effect.
