Overview
11 DESCRIPTION Buprenorphine sublingual tablet is uncoated, round, biconvex, white to off-white tablet. It contains buprenorphine hydrochloride USP, a partial agonist at the mu-opioid receptor, and is available in two dosage strengths, 2 mg buprenorphine and 8 mg buprenorphine (as the free base, equivalent to 2.16 mg buprenorphine hydrochloride USP and 8.64 mg buprenorphine hydrochloride USP).
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Buprenorphine sublingual tablet contains buprenorphine, a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor. 12.2 Pharmacodynamics Subjective Effects Comparisons of buprenorphine to full opioid agonists such as methadone and hydromorphone suggest that sublingual buprenorphine produces typical opioid agonist effects which are limited by a ceiling effect. Opioid agonist ceiling-effects were also observed in a double-blind, parallel group, dose-ranging comparison of single doses of buprenorphine sublingual solution (1 mg, 2 mg, 4 mg, 8 mg, 16 mg, or 32 mg), placebo and a full agonist control at various doses.

Interactions
- 7 DRUG INTERACTIONS Table 3 includes clinically significant drug interactions with buprenorphine. Table 3. Clinically Significant Drug Interactions Benzodiazepines or other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effects, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, increases the risk of respiratory depression, profound sedation, coma, and death. Intervention: Cessation of benzodiazepines or other CNS depressants is preferred in most cases of concomitant use.
