What buprenorphine dose was the patient advanced to in the described case?

• A. 8 mg per day
• B. 12 mg per day
• C. 16 mg per day
• D. 20 mg per day

Answer: (C)

Advancing buprenorphine to 16 mg per day reflects reaching a commonly effective maintenance level that provides strong control of withdrawal symptoms and cravings while staying within a safe, tolerable range for many patients. Buprenorphine is a partial mu-opioid receptor agonist with a ceiling effect on respiratory depression, which allows clinicians to increase the dose when needed to achieve better symptom relief without a linear increase in safety risk. In this described case, 16 mg daily achieved adequate receptor occupancy and clinical response, making it the appropriate escalation.

Lower doses (for example, 8 mg) may be insufficient for ongoing withdrawal control or cravings in some patients, while 12 mg might be adequate for some but not for others. A higher dose like 20 mg is used only in select cases with very high tolerance or specific clinical indications and was not the dose described here.
