The National Alliance of Advocates
for Buprenorphine Treatment

Buprenorphine (Suboxone®, Subutex®3, Zubsolv®4, Bunavail™5, Probuphine®6) is an opioid medication used to treat opioid addiction in the privacy of a physician's office.1 Buprenorphine can be dispensed for take-home use, by prescription.1 This, in addition to the pharmacological and safety profile of buprenorphine, makes it an attractive treatment for patients addicted to opioids.2

What is ZubsolvĀ®?


Zubsolv® is a schedule III buprenorphine/naloxone combination medication specifically indicated (and FDA approved) for the treatment of opioid addiction. Along with Suboxone®, its generic equivalents, Subutex® (discontinued in the US), its generic equivalents, Zubsolv is a medication subject to DATA-2000.

FDA approved on July 3, 2013 and commercially launched in September 2013, Zubsolv is the first brand name competitor to Suboxone. Manufacturer copay card available - up to $225 off

Zubsolv has a higher bioavailability than Suboxone and as a result comes in different doses than Subxone or generics. Zubsolv comes in sublingual tablet sizes of 5.7-mg/1.4-mg (buprenorphine/naloxone), and 1.4-mg/0.36-mg (buprenorphine/naloxone) both have equal bioavailability to 8mg/2mg and 4mg/1mg of competing buprenorphine/naloxone products, respectively.

UPDATE: On March 6, 2015 Orexo US, Inc. announced the FDA approval of the new 8.6mg/2.1mg dosage strength of ZUBSOLV®. This corresponds to 12mg/3mg of generic bup/nx dosing.

Zubsolv is individually packaged to reduce accidental pediatric exposure.
