Lawnmower AddictL.A. is a 42 Y.O. male who broke his ankle while mowing wet grass across an incline. After several surgical attempts including failed pinning operations, his foot is rotated 60 degrees out of alignment and he has chronic pain. Prior to this injury L.A. had a history of opioid addiction. He states that he is committed to recovery and participates in 12-step N.A. meetings but he abused his last oxycodone prescription and experienced a relapse. His goal is to achieve pain relief without relapse to opioid abuse.

Enduring pain to avoid relapseE.P. is a 40 y.o. married male with 4 children, He has been in opioid addiction recovery for over 9 years. I received a tearful midnight call from his wife stating the E.P. was lying in bed in a fetal position, moaning in pain and refusing to take opioid analgesics after incurring a back injury while wrestling with his son who is a star member of the high school wrestling team. His goal is to never relapse to active opioid addiction.

Scope of the Public Health Problem
An estimated 2.4 million people have used heroin at some time in their lives(NHSDA, 1998)
During 1996 through 1998, an estimated 471,000 persons used heroin for the first time. Of them, 25% were under age 18 and another 47% were age 18 - 25 (NHSDA, 1999)

What about abuse?
According to the National Institute on Drug Abuse (NIDA), in 1999 Four million Americans reported current use of prescription drugs for non-medical purposes
The most dramatic increases were found among the 12 to 25 year olds
Oxycontin® and Ritalin® were among the most cited abused medications

Narcotic Abuse Taxes ED Resources In 2001 there were an estimated 90,232 ED
visits, a 117% increase since 1994 “Dependence” was the most frequently
mentioned motive for abuse (44% of cases) Between 2000 and 2001 Oxycodone mentions
increased 70% and accounted for 53.7% of the overall increase in narcotic abuse cases during that year.

Access to treatment is limited
Of the estimated 810,000 opioid dependent persons in the U.S. only 170,000 maintenance treatment slots exist.

The Journey Matters
![Page 14: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/14.jpg)
Therapeutic drug use:
Drug use to treat or diagnose illness. Almost everyone has taken a drug at one time or another because they were sick.
A direct and reliable drug effect is expected. Antibiotics kill bacteria regardless of the sick person’s belief in the medicine. The drug is a known entity.
There are rules. The prescription tells: what to take, how much to take, and when to take it. A person who violates the rules must own the consequences.
![Page 15: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/15.jpg)
Social Drug Use
Drugs are used to increase social interactions.
Rules are vague or non-existent. Drug supply is uncertain Most cases of addiction result from social
drug use that gets out of control.
![Page 16: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/16.jpg)
A Basic Distinction
High seeking = Pain relief seeking “Because 6 to 15% of the U.S. population
abuses drugs, the history of pain management is marked by the undertreatment [of pain in] the other 85 to 94%.”
Passik SD quoted in: Gilson AM and Joranson DE (2002) U.S. Policies Relevant to the Prescribing of Opioid Analgesics for the Treatment of Pain in Patients with Addiction Disease Clinical Journal of Pain 18:S91-S98. available at http://www.medsch.wisc.edu/painpolicy/
![Page 17: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/17.jpg)
Pain Statistics
Most common reason that people seek medical care 50 million Americans are partially or totally disabled
due to pain Annual cost to U.S. society estimated to exceed $100
billion 50-80% of patients with pain report that their pain
is inadequately managed Risk of undertreatment is increased among those
with a history of substance abuse
![Page 18: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/18.jpg)
Addiction Defined
Addiction is compulsive use with loss of control and continued use despite adverse consequences.
![Page 19: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/19.jpg)
Elements of Compulsivity:
Constant thought of drug acquisition Anticipation of opportunities to use Defer other priorities of life Unable to resist desire to use
![Page 20: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/20.jpg)
Aspects of Loss of Control
Inability to use in moderation consistently
Easier to abstain completely Frequent episodes of excessive use
![Page 21: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/21.jpg)
Continued use despite problems
Loss associated with use Multiple crisis not seen as drug-related Sincere promises to self and others to quit
![Page 22: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/22.jpg)
Signs of Psychological Dependence
Carrying Drugs Using Drugs alone Stockpiling Drugs Concern over supply Changing friends Finding excuses to use Using at inappropriate times Willingness to take increasing risks

Addiction Characteristics
First priority is drug acquisition and use Negative consequences occur in order
1) Interpersonal relationships suffer2) Productivity declines3) Self-Esteem plummets4) Health problems emerge or worsenNote: Legal problems can occur at any time.

Why Treatment ?
Dysfunctional lifestyle of opioid addiction makes treatment a desired alternative
Oral methadone and buprenorphine sublingual tablets are approved for both medical withdrawal and medical maintenance
Rewards
Negative consequences
Utility Theory

Addictive Behaviors
Selling prescription drugs Prescription forgery Stealing drug from others Injecting oral formulations Buying drugs on the street Resistance to change therapy despite
evidence of adverse effects from the drug
![Page 29: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/29.jpg)
Drug-seeking behavior misidentified by health providers as addictive behavior, when it is actually relief-seeking behavior
Behaviors resembling those of drug addiction disappear when patient is given adequate doses of analgesia
Pseudo-addiction
![Page 30: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/30.jpg)
Pseudoaddiction Behaviors
Complaints for more drug Hoarding drug during pain free periods Specific drug requests Openly seeking other sources of help Occasional unsanctioned dose increases Resistance to change in therapy
![Page 31: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/31.jpg)

addiction Don’t mistake pain relief seeking for drug
seeking - pseudoaddiction

Pain Management and Addiction
Confusion over the distinction between physical dependence (a state of adaptation that produces withdrawal signs upon abrupt drug discontinuation) and addiction (DSM-IV Substance Dependence) has confounded approaches to the patient in pain.
![Page 47: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/47.jpg)
Misconception: Therapeutic use of opioids is commonly associated with substance abuse or addiction
Reality: In patients with no history of substance abuse the risk of addiction following therapeutic use appears to be less than 3%
Misconception regarding pain management with opioids
![Page 48: Controlled Substance Management or Doctor I need Oxy Tony Tommasello, Ph.D. University of Maryland School of Pharmacy Office of Substance Abuse Studies.](https://reader035.fdocuments.us/reader035/viewer/2022062511/55164ec9550346a2698b4adf/html5/thumbnails/48.jpg)
Clinical Features Distinguishing Opioid Use in Patients With Pain Versus Patients Who Are Addicted to Opioids (TIP 40)
Clinical features Pain Pt. Addicted Pt.
Compulsive drug use
Crave drug (when not in pain)

Corresponding Responsibility Rule21 CFR 1306.04 A prescription for a CDS to be effective must be issued for a
legitimate medical purpose by an individual practitioner acting in the usual course of his professional practice. The responsibility for the proper prescribing and dispensing of CDS is upon the prescribing practitioner, but a corresponding responsibility rests with the pharmacist who fills the prescription. An order purporting to be a prescription issued not in the usual course of professional treatment or in legitimate and authorized research is not a prescription and the person knowingly filling such a purported prescription as well as the person issuing it shall be subject to the penalties provided for violations of the provisions of law relating to CDS.

Prescription Drug Monitoring Programs Electronic PDMP passed in 2006 Maryland
general session (SB 333 & HB 1287) and was vetoed by Gov. Ehrlich on May 26, 2006.
As of April 2005, 22 states already adopted electronic PDMPs
Of the various PDMP approaches (serial Rx, triplicate) electronic systems are the least intrusive and “chilling” on prescribing practices.

Consult addiction medicine specialist When opioids are necessary, use long-acting,
slower onset formulations when possible Must D/C buprenorphine in order to obtain full
agonist effect of mu agonists.

Misconception regarding pain management with opioids Misconception: patients on methadone
maintenance therapy should not be experiencing pain
Reality: “Reluctance to provide adequate pain treatment to patients on medication assisted therapy usually is based on the mistaken belief that a maintenance dose of opioid addiction treatment medication also relieves acute pain” (TIP43 p174)

Guidelines for Methadone Patients Don’t expect the patient’s methadone
maintenance dose to provide analgesia Continue patient’s maintenance dose Add analgesic (opioid and otherwise)
starting with usual doses Anticipate tolerance and the need for
higher dose requirement

Conclusions
There is no easy formula for dealing with this common yet complex area of patient care
Engage addiction specialists sooner rather than later

Conclusions
Consider referral to pain management specialist when standard approaches fail and discomfort sets in – before the situation has escalated out of control.
Employ the assistance and cooperation of a competent pharmacist who maintains a patient centered pharmacy practice.
