Disclosures Drs. Pinto and Saffier have no financial interest or other relationship with the manufacturer of any commercial product discussed in this presentation.
Learning Objectives At the end of this presentation, participants will be able to: • List at least 2 patient criteria needed for buprenorphine treatment. • Explain why an opioid dependent patient must be in opioid withdrawal prior to taking their first dose of buprenorphine. • Understand and experience aspects of what a buprenorphine treatment group is like.
Number of mentions . Oxycodone and hydrocodone both registered substantial increases in emergency department mentions in the last 5 years Source: SAMHSA, Drug Abuse Warning Network. 2/2004
Past Year Dependent/Abusers, Ages 12 or Older (in Thousands) • Over 2 million are estimated to be dependent on or abusingprescription drugsin the past year. Source: SAMHSA, 2002 National Survey on Drug Use and Health. 1/2004

Opioids – a brief overview • Agonist • Heroin, hydrocodone, oxycodone, fentanyl • Antagonist • Naloxone, naltrexone • Mixed agonist/antagonist • Pentozacine, butorphanol (Stadol) • Partial agonist • Buprenorphine

Buprenorphine– a partial agonist • High affinity for the mu opioid receptor • Competes with other opioids and blocks their effects • Can precipitate withdrawal in highly opioid dependent individuals • Slow dissociation from the mu receptor • Prolonged therapeutic effect for opioid dependence treatment • “Ceiling effect” for stimulation of a given receptor
Buprenorphine– a partial agonist • Poor oral bioavailability • Fair sublingual bioavailability • Takes about 10 minutes to dissolve • Schedule III drug • With naloxone (4:1) (Suboxone) or without (Subutex) • Analgesic dose for mild to moderate pain is 0.3 – 0.6 mg. (0.4 mg = ~10 mg morphine)
Who is an appropriate patient? • Opioid dependent • Wants to stop using • Psychiatrically stable • Interested in office-based care • Reliable – can keep appointments • Agrees to urine tox screens • Has social support
Meet Ryan - • Went to the ED in withdrawal. • Longstanding use of OxyContin. • $100/day “habit”. • Snorts q day for months, then stops. • Moves back to the Bay Area and within days, he’s back to using.
“I’m tired of snorting Oxies, Doc. Can you help me?” • I’m snorting 5 oxies per day – it’s an insane amount to be putting into my body. • My palms are sweaty in the morning. • Then I have intense pain in my thighs. • I feel fidgety to an extreme. • So much physical and mental anguish. • I don’t want to waste money on this. It’s destroying my life.
Dysphoric mood Craving Irritability Tearing, rhinorrhea Fever, chills Sweating Gooseflesh (cold turkey) Dilated pupils Muscle aches Back pain Tremor Yawning Restless sleep, then Insomnia Anorexia N/V, diarrhea, cramps Opioid Withdrawal
Uses of Buprenorphine • Buprenorphine maintenance • Short acting opioids • Long acting opioids • Buprenorphine detox • Buprenorphine taper • (As an analgesic (buprenex))
