ZUBSOLV

AbsorptionPlasma levels of buprenorphine and naloxone increased with the sublingual dose of ZUBSOLV. There was wide inter-patient variability in the sublingual absorption of buprenorphine and naloxone, but within subjects the variability was low. Both C max and AUC of buprenorphine increased with the increase in dose (in the range of 1.4 mg to 11.4 mg), although the increase was not directly dose-proportional. Naloxone did not affect the pharmacokinetics of buprenorphine. ZUBSOLV has been shown...

The induction of buprenorphine therapy with ZUBSOLV was evaluated in two blinded randomized, non-inferiority studies. The identical blinded induction phase component of the studies was designed to assess the tolerability of ZUBSOLV versus generic buprenorphine tablets when used as initial treatment, as measured by retention in treatment. The studies included opioid dependent (DSM-IV criteria) male and female patients 18 to 65 years of age. Induction doses for generic buprenorphine tablets were 8 mg for day 1 and 8 mg or 16 mg for day 2. The induction doses for ZUBSOLV were 5.7 mg/1.4 mg for da...

ZUBSOLV is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions ( 5.9 )]. Hypersensitivity to buprenorphine or naloxone. ( 4 )

Addiction, Abuse, and Misuse : Buprenorphine can be abused in a similar manner to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Multiple refills should not be prescribed early in treatment or without appropriate patient follow-up visits. ( 5.1 ) Respiratory Depression : Life-threatening respiratory depression and death have occurred in association with buprenorphine use. Warn patients of the potential danger of...

7 DRUG INTERACTION S Table 4 includes clinically significant drug interactions with ZUBSOLV. Table 4. Clinically Significant Drug Interactions with ZUBSOLV Benzodiazepines and other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effects, the concomitant use of benzodiazepines and other CNS depressants, including alcohol, increases the risk of respiratory de...
