Here is a sneak peak

A 43-year-old woman presents to the emergency department via emergency medical services after ingesting an unknown amount of buprenorphine-naloxone. The patient is noted to be extremely agitated and physically aggressive with emergency department staff, necessitating physical restraints. The patient is sedated with 2 mg of intramuscular lorazepam and states that she took her roommate’s buprenorphine-naloxone because she ran out of her own methadone. Which of the following best describes the activity of buprenorphine at the mu opioid receptor?

A. Antagonist

B. Full agonist

C. Inverse agonist

D. Partial agonist

Answer D

Buprenorphine is an opioid that has high affinity and partial activity at the mu opioid receptor. These features allow for buprenorphine to be an effective alternative to methadone in weaning patients off of opioids while preventing withdrawal symptoms. Conversely, if buprenorphine is taken while full agonists like methadone are still present in the patient, then the buprenorphine will displace the full agonist and induce withdrawal symptoms since the patient is getting a reduced opioid effect. Many people falsely believe that the naloxone found in buprenorphine products induces withdrawal in these patients, but naloxone has negligible bioavailability when taken via the oral route.

Graphic Agonist & Antagonists

An example of an antagonist (A) at the mu opioid receptor would be naloxone. Naloxone competitively binds to the mu receptor but does not activate the receptor, making it ideal as a reversal agent in the setting of opioid overdose. A full agonist (B) will bind to the mu receptor and elicit a full response. Agents like morphine,methadone,and fentanyl are all examples of full mu receptor agonists. An inverse agonist (C) is an agent that binds to a receptor and induces the opposite effect (e.g., inverse agonists at GABA-A receptors induce seizures). There are exceedingly few inverse agonists currently used in clinical medicine.

One Step Further

What is the purpose of adding naloxone to oral preparations of buprenorphine?

It is designed to deter parenteral administration of oral buprenorphine products.
