grim data
Grim data

The United States of America:

  • constitutes ~ 5% of the world’s population
  • consumes 80% of the global legal opiod supply
  • consumes 99% of the global hydrocodone supply
  • consumes 66% of the global illegal drug supply

opioids in chronic pain systemic review of efficacy and safety
Opioids in chronic pain: systemic review of efficacy and safety
  • 11 trials
  • Mean pain relief ~ 30%
  • Only 44% of open-label opiod patients elected to continue therapy
  • Dropout rate due to side effects ~ 33%
  • 5 of 8 studies failed to show improved function

Kalso E, et al. Pain 2004;112:372-380

laboratory monitoring of oxycontin oxycodone clinical pitfalls
Laboratory monitoring of Oxycontin™ (oxycodone): clinical pitfalls
  • Suspected patient of abusing or misusing (selling?) OxyContin™
    • Frequent requests for dose escalation due to poor headache pain control
  • Urine-based immunoassay oxycodone drug screen was negative
  • Dismissed the patient from the physician’s practice
  • At the (distraught) patient's request, a second test using gas chromatography- mass spectrometry (quantitative, more sensitive) was performed on original urine sample, results were positive
  • For the urine-based immunoassay, the minimum level threshold was too high to detect the presence of oxycodone
  • Communication is essential

end organ damage possibly associated with chronic migraine
End Organ Damage Possibly Associated With Chronic Migraine

“…..exposure to repeated attacks and sustained doses of analgesics appears to result in brainstem changes as patients progress from EM to CM…..they [brainstem changes] will tend to increase attack frequency and hence analgesic consumption.”

  • ~78,000 responses
  • Narcotic data from subset analysis of ~ 28,000 “severe headache” patients, 2005 to 2009

medication use among all migraineurs
Medication use among all migraineurs
  • 18% triptans
  • 12% narcotics
  • 6% butalbital-containing product

ampp narcotic use among severe sufferers
AMPP narcotic use among “severe” sufferers
  • 70% non-narcotic users
  • 16% current narcotic users (within last 90 days)
  • 14% previous users (use during 2005-2008, but no current use)
  • Among narcotic users:
    • 66% used one narcotic agent
    • 20% use two agents
    • 8% used three agents
    • 94% also consumed at least one non-narcotic headache medication
ampp narcotic use among severe sufferers1
AMPP narcotic use among “severe” sufferers
  • 42% were prescribed hydrocodone product
  • 23% acetaminophen with codeine
  • 21% acetaminophen with propoxyphene
ampp narcotic use among severe sufferers2
AMPP narcotic use among “severe” sufferers
  • Compared to non-narcotic users, narcotic users had statistically significantly more:
    • Depression and/or anxiety
    • Consumption of health care resources (physician visits, ER visits, specialists visits)
    • Likelihood to be unmarried, unemployed, and have a lower household income
when to consider chronic narcotics for headache
When to consider chronic narcotics for headache?
  • Individualized
    • Greater than 15 days/month, intractable severe pain unresponsive to reasonable outpatient (inpatient?) therapies administered over the span of months to years
    • Absence of significant psychiatric disorders, including absence of addiction history
  • Practitioner dependent
    • Knowledge with prescribing nacotics - > consider referral
    • Resources for continual monitoring
  • Established practitioner/patient relationship
scheduled narcotic therapy for chronic headache
Scheduled narcotic therapy for chronic headache
  • Potential advantages
    • Improved functionality
    • Provides continuous, often pre-emptive pain-relief
    • Restore proper pathophysiology of dysfunctional CNS opioid functions?
    • Improved quality of life
    • others
  • Potential disadvantages
    • Tolerance/habituation
    • Misuse/abuse
    • Medication-induced headache/hyperalgesia?
    • tolerability
some keys to success
Some keys to success
  • Consider narcotic contract with patient
    • Single prescriber, no replacements for “lost” prescriptions, no “missed” appointments, family/partner input
  • Documentation
    • indication, expected benefits/risks, reasons for discontinuation, potential for withdrawal, etc.
  • Psychological services – initial and ongoing
  • Routine monitoring
    • functional status
    • adverse effects
    • inappropriate use – self-treating anxiety, insomnia, etc.
    • drug screen
more keys
More keys
  • Educate patient
    • Sparse published literature to support opioid use
    • Little long-term efficacy data
    • No long-term safety studies

dependence related behavior in medication overuse headache moh
Dependence-related behavior in medication-overuse headache (MOH)
  • 80% of individuals presenting to specialized headache centers with CDH are over-using acute medications, majority of which are narcotics
  • Lack of universally accepted MOH definition
  • MOH cause of, or consequence of, chronic headache
  • Difficult to determine without psychological assessment
  • Referral?

Headache 2010;50:1597-1611

medication overuse headache moh and dependence
Medication overuse headache (MOH) and dependence
  • Risk factors for dependence on acute medications
    • History of migraine, history of opiod overuse, previous withdrawal
  • “MOH thus appears to belong to the spectrum of addictive behaviors. In clinical practice, behavioral management of MOH should be undertaken besides pharmacological management.”

Headache 2008;48:1026-1036.

differences in the personality profile of moh suffers and drug addicts mmpi 2 results
Differences in the personality profile of MOH suffers and drug addicts: MMPI-2 results
  • MOH patient – chronic pain controls the user’s behavior (e.g. seeking medications to avoid pain)
  • Addict – drug use controls the user’s behavior (e.g. seeking medications for euphoria and/or avoid withdrawal)

Headache 2011;51:1212-1227.

repeater phenomenon
“Repeater” phenomenon

  • In comparison to non-repeaters, repeaters are more:
    • Triptan-naïve
    • More alexithymic
    • Depressed

do butalbital containing products bcp have a role in the management of migraine
“Do butalbital-containing products (BCP) have a role in the management of migraine?”
  • Butalbital-containing products (BCP) given to 17% to 36% of diagnosed migraineurs, often as treatment of choice
  • National Ambulatory Medical Care Survey
  • #1 = BCP with 2.3 million prescriptions
  • NOT A SINGLE TRIAL EXISTS DEMONSTRATING BCP ARE EFFECTIVE FOR MIGRAINE
  • BCP are well-established causes of dependency, withdrawal symptoms, MIH, poorly controlling migraine
  • Women are 164% more likely than men to get a BCP

slide50
Scant evidence to support BCP or narcotics as migraine treatments, especially as drugs of choice

“No randomized, placebo-controlled studies prove or refute efficacy for [BCP] in the treatment of acute migraine headaches …. Based on concerns of over-use, medication overuse headache, and withdrawal, the use of [BCP] should be limited and carefully monitored.”

US Headache Consortium’s evidence-based migraine treatment guidelines

.

narcotics
Narcotics

In an otherwise healthy, non-pregnant person, narcotics are difficult to rationalize as the treatment of choice for any primary headache disorder

Narcotics are woefully over-prescribed as initial treatments and in the Emergency Department…often yields unintended consequences

Narcotics work best as “rescue” medications for when migraine-specific medications fail, thus your goal is now pain relief, instead of reversal of the attack and return to normal function
