What are the differences between Buprenex, Butrans, Buprenorphine, Suboxone, and Subutex?

All of these medications are similar in that they contain a shared active ingredient buprenorphine hydrochloride.  They are all different medications with the exception of buprenorphine which is the active ingredient in all medications.  There are subtle differences between each of the medications Buprenex, Buprenorphine, Suboxone & Subutex.   The main differences are in the dosing, usage and marketing of the medications.  Some contain additional active ingredients that make the drug combination useful for different purposes.

The table below is a basic summary of the differences between Buprenex, Butrans, Buprenorphine, Suboxone, and Subutex.

Buprenex

Buprenex is typically marketed for animals such as cats and dogs. Buprenex contains the same active ingredient as all buprenorphine medications.  Buprenex does not contain Naloxalone like other versions of the drug because it is not intended to be used for withdrawal of opiates.

 

Buprenex Injection

Buprenex Injection

Proprietary / Brand Name: Buprenex

Generic Name: buprenorphine (byoo-pre-NOR-feen)

Active ingredients: buprenorphine HCI (buprenorphine)

 

 

 

 

Butrans

A strong prescription pain medicine that contains an opioid (narcotic) that is used to treat moderate to severe around-the-clock pain.

Butrans5mcgButrans10mcgButrans20mcgButrans is a partial opioid agonist product indicated for the management of moderate to severe chronic pain in patients requiring a continuous, around-the-clock opioid analgesic for an extended period of time.  Each Transdermal patch is designed to deliver medication over a 7 day period.

BUTRANS is a rectangular or square, beige-colored system consisting of a protective liner and functional layers. BUTRANS is available in three strengths:

  • BUTRANS 5 mcg/hour Transdermal System (dimensions: 45 mm by 45 mm)
  • BUTRANS 10 mcg/hour Transdermal System (dimensions: 45 mm by 68 mm)
  • BUTRANS 20 mcg/hour Transdermal System (dimensions: 72 mm by 72 mm)

Suboxone

Suboxone is indicated for the treatment of opioid dependence.  Suboxone contains Buprenorphine HCI and Naloxone HCI.  Administer Suboxone sublingual film or tablets sublingually as a single daily dose.  Suboxone film and tablets come in two sublingual dose sizes: 2 mg buprenorphine with 0.5 mg naloxone and 8 mg buprenorphine with 2 mg naloxone.

Suboxone Tablets

Tablets vs Film

Patients being switched between SUBOXONE (buprenorphine and naloxone) sublingual tablets and SUBOXONE sublingual film should be started on the same dosage as the previously administered product. However, dosage adjustments may be necessary when switching between products. Because of the potentially greater relative bioavailability of SUBOXONE sublingual film compared to SUBOXONE (buprenorphine and naloxone) sublingual tablets, patients switching from SUBOXONE (buprenorphine and naloxone) sublingual tablets to SUBOXONE sublingual film should be monitored for over-medication. Those switching from SUBOXONE sublingual film to SUBOXONE (buprenorphine and naloxone) sublingual tablets should be monitored for withdrawal or other indications of under-dosing. In clinical studies, pharmacokinetics of SUBOXONE sublingual film was similar to the respective dosage strengths of SUBOXONE (buprenorphine and naloxone) sublingual tablets, although not all doses and dose combinations met bioequivalence criteria.

 

Subutex

Subutex is indicated for the treatment of opioid dependence.  Subutex contains buprenorphine HCI and does not contain Naloxone like its’ brother Suboxone.

The pharmocokinetic properties of Suboxone and Subutex are very similar

 Summary

While each of these medications are similar, there are significant differences in the delivery, dosage, delivery and purpose.  This information was compiled using many sources and should be used for entertainment purposes only.
