FDA Approves Orexo Zubsolv New Dosage

FDA has approved an Orexo U.S. supplemental NDA for Zubsolv (buprenorphine/naloxone sublingual tablet) 0.7mg/0.18mg for treating patients with opioid dependence. The approval adds a new dosing option to Zubsolv’s existing approved dosing range that includes 11.4mg/2.9mg, 8.6mg/2.1mg, 5.7mg/1.4mg, 2.9mg/0.71mg, and 1.4mg/0.36mg. The drug was originally approved 7/2/2013 in two dosages — 5.7mg/1.4mg and 1.4mg/0.36mg sublingual tablet strengths.

The company notes that the sublingual tablets can be abused in a manner similar to other opioids. “Clinical monitoring appropriate to the patient's level of stability is essential,” it says. “Liver function tests should be monitored before and during treatment.”
