ZUBSOLV (buprenorphine and naloxone) sublingual tablets are white menthol-flavored tablets in a triangular shape for the lower dosage strength (1.4 mg /0.36 mg) and a round shape for the higher dosage strength (5.7 mg/1.4 mg). They are debossed with the respective dosage strength of buprenorphine. They contain buprenorphine HCl, a mu-opioid receptor partial agonist and a kappa-opioid receptor antagonist, and naloxone HCl dihydrate, an opioid receptor antagonist, at a ratio of 4:1 (ratio of free bases). ZUBSOLV is intended for sublingual administration and is available in two dosage strengths, 1.4 mg buprenorphine with 0.36 mg naloxone and 5.7 mg buprenorphine with 1.4 mg naloxone.
