Slide 25-

Transmission The synaptic cleft is the narrow intercellular space between neurons. Neurotransmitters cross the synaptic cleft and bind to specific receptors on the postsynaptic neurons This will excite or inhibit the postsynaptic neurons.

Mentholatum Menthol generates analgesic activity through: Ca2+ channel blocking activity Binding to kappa opioid receptors Stanos, S.P., 2007
Slide 37-

Methyl Salicylate Toxicity Salicylic acid derivative (a.k.a. wintergreen oil, sweet birch oil) Lipid solubility increases toxicity More toxic than aspirin 1 teaspoon (5ml) wintergreen oil contains 4,000 mg salicylate 30ml wintergreen oil is a fatal dose in adults Risk of toxicity reduced with use for acute pain, limited to a small area of dermal application Chyka, P.A., et al., 2007
Slide 38-

Anticonvulsants Inhibit sustained high-frequency neuronal firing by blocking Na+ channels after an action potential, reducing excitability in sensitized C-nociceptors. Blockade of Na+ channels and increase in synthesis and activity of GABA, in inhibitory neurotransmitter, in the brain. Modulates Ca+ channel current and increases synthesis of GABA. Deglin, J.H. & Vallerand, A.H., 2001
Slide 39-

Antiepileptic Agents Broad clinical actions in the CNS: Reduce seizures Neuropathic pain Bipolar disorder Anxiety Schizophrenia Agitation Impulse dyscontrol Dementia Delirium Three proposed mechanisms of action: Blockade of voltage gated sodium channels ( glutamate release) Blockade of voltage gated calcium channels – alpha 2 delta subunits (reduces excessive neurotransmitter release) Enhancement of GABA actions

Reference: Am Family Physician, 71(7), 2005 Methadone FDA Indications: Severe pain, narcotic detoxification, and temporary maintenance of narcotic addiction
Slide 50-

Methadone Inexpensive Accumulates with repeated dosing 85% protein bound Slowly released up to 10 days after dose increase Available in 10 mg tablet or oral solution, use of 40 mg diskette no longer available for pain mgt use Patient may be subjected to scrutiny, stigma & misconceptions
Slide 51-

Federal Regulation Prevention of withdrawal in opioid addiction Special annual registration with DEA Use only in an established addiction treatment program Maintenance patients may continue tx when admitted to acute care facility Treatment for pain Any clinician licensed to prescribe Schedule II drugs may prescribe methadone for pain
Slide 52-

Methadone Incomplete Cross-Tolerance Inverse relationship with dosing Monitor ekg for QT prolongation
Slide 53-

Schmittner, J., 2006 Clinical Indications for Electrocardiogram in Patients Receiving Methadone History of long-QT syndrome or torsades de pointes Family history of long-QT syndrome or early sudden cardiac death Cardiac arrhythmia and heart block (2nd or 3rd degree AV block) Anorexia nervosa Frequent electrolyte depletion (K, Ca, Mg) HIV patients on multiple-antiretroviral therapy Methadone dosages greater than 150mg/day Initiation of a P-450 inhibitor Initiation of medications associated with QTc prolongation Presyncopal or syncope symptoms Unexplained tonic-clonic seizures with abnormal electroencephalogram
Slide 54-

Routhier, D., et al., 2007
Slide 55-

Methadone Black Box Warning Deaths during initiation and conversion from other opioids Respiratory depression – chief hazard Use of concomitant sedatives including alcohol Self-titration – iatrogenic overdose QTc prolongation
Slide 56-

Key Teaching Points Careful of mix up between long acting and short acting with same mg amount (ex. MS Contin and MSIR) Remove old patch before new one put on Safe disposal issues Drinking, driving issues Tell all of your healthcare providers everything that you take, always Careful about buying on the Intranet Sleepers, sedatives Teach S & S of withdrawal
Slide 57-

Key Teaching Points Never take more or less than prescribed without calling us Only you take your pain medication, do not share! Never alter the medication, i.e. splitting sustained release medications Keep in a safe place always! Medication parties Middle & High School students; #1 medicine cabinet thefts Inciardi, J.A., et al., 2007
Slide 58-

Slide 59-

Some of our biggest safety issues Careful of look alike names and sustained release versus immediate release Only witness waste when you see it first, protect your hard earned license Careful of which line is which PCA pumps; double check, double check and double check-settings and syringe concentration, medication and document Instruct patient only to press button ISMP, February 2007

Endocannabinoids Research on the adaptations of cells continue with the recent discover of the cannabinoid receptor and the subsequent searching and findings of the endogenous cannabinoids. Two endocannabinoids, anandamine and 2-arachidonyl glycerol or 2-AG.
Slide 67-

Endocannibinoids Found in most brain function Equal balance between endocannibinoids and their receptors occur (Fride, 2005) Role in brain plasticity leading to long term effects on movement and coordination habit formation reward and addiction

What is Flare of Pain? Same Pain as Chronic (Persistent) Pain Same Location as Chronic (Persistent) Pain Different Pain Intensity from Chronic (Persistent) Pain Temporary increase in pain intensity from a more stable baseline pain with otherwise similar characteristics.
Slide 74-

Pain Flare Study 2001-2002 Pain Flare Study Descriptive study N= 67 Location: University of Minnesota – Fairview Pain Management Center Survey mailed to 75 patients, 67 responses IRB approval
Slide 75-

Pain Flare Study Purpose of study Describe the characteristics of and factors contributing to pain flares in patients with chronic pain who receive care from the nurse practitioner in Fairview Pain Management Center
Slide 76-

Conclusions Pain Flare definition: Same Pain, same location, different intensity This definition implies that Pain flare should not represent new pathology Patient has an ongoing pain problem that has been relatively stable No presumption of what baseline pain intensity was
Slide 77-

Conclusions Studying flare gives meaning to the patients experiences of flare of their pain Gave patients a “voice” Assurance that it is not permanent condition Universality of flares in chronic pain Pain intensity rating less important in chronic non-malignant pain than changes in pain intensity Once contributing factors to pain flares have been resolved, chronic pain returns to baseline
Slide 78-

Envision the Future Better pain control with fewer side effects Genome pain management Helping the brain erase persistent pain Social Policy that enhances comprehensive approach to pain management rather than reinforce procedures to get rid of pain Abuse deterrent opioid formulations that significantly reduce diversion and are available for those who need it.
