Glenview, IL 60025. 51 year old white female patient with chronic pain due to MVA Current Medications: MS Contin 30mg TID Hydrocodone/APAP 5/500 1-2 tabs qid prn (patient states she take 6 tabs/day) Atenolol 50mg qday Senokot-S 1 tab bid MD asks you to convert this patient to oxycodone due to recent increased itching and ineffective control of pain. 1) Conversion: Total oxycodone equivalent/day: 90mg morphine + 30mg hydrocodone 90mg morphine = 30mg hydrocodone = 60mg oxycodone + 20mg oxycodone 80mg (total oxycodone dose) 2) Should we suggest the total oxycodone dose or reduce? 2) Reduction of Dose: Total oxycodone equivalent/day: 80mg 80mg x 0.25 = 20 mg so reducing by 25% the total daily dose would be 60mg oxycodone 3) How do we want to give the oxycodone 60mg? Slow versus immediate release? 3) How do we want to give the oxycodone 60mg? ◦ Oxycontin 15mg TID plus oxycodone 510mg tid prn (start with 5mg) ◦ Patient would be taking 45mg + 15-30mg = 60-75mg ◦ Could switch morphine to oxycodone, keep on hydrocodone prn dose for first few days, reassess then switch to oxycodone Other considerations: 1. What other medications may this patient benefit from? 2. How would you have established this? 3. Does patient need high dose of opioid? 4. Has patient tried other modes of therapy such as stretching (Physical therapy involvement), massage, TENS unit or cognitive behavioral therapy (non-drug methods)? Essential to identify if: ◦ ◦ ◦ ◦ Patient successful Patient might benefit more with restructuring of treatment Need treatment for addiction Benefits outweighed by harm Frequency of monitoring: ◦ Patient on stable doses ◦ Every 3-6 months After initiation of therapy, changes in opioid doses, with a prior addictive disorder, psychiatric conditions, unstable social environments Weekly basis may be necessary Chou, R, Fanciullo, G, Fine, P, et. al.

Consider for patient not well known and/or higher risk of misuse Example of components of opioid agreement: ◦ Specified the conditions under which opioids would or would not be prescribed ◦ Patient responsibilities Only receive opioids from Dr. ________ Will not give medications to anyone else If my prescription runs out early for any reason; have to wait until next prescription is due. Example of an Opioid Management Agreement: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1 829426/figure/Fig1 Random urine drug screening performed if recommended by the physician to monitor adherence and possible use of illicit substances. Patients informed that the agreement would be discontinued if patient responsibilities were not met. Responsibilities of the physician and/or clinic staff included providing monthly prescriptions on the due date, monitoring the effects of therapy, and providing ongoing care. Patient signs agreement Pharmacies licensed by the MN Board of Pharmacy and other dispensing facilities are required to report the dispensing of controlled substances listed in the state’s Schedules II-IV. ◦ Data is submitted electronically. Patient controlled substance prescription history is available to prescribers and pharmacists Available 24/7, 365 days a year, with information such as: ◦ Quantity and dosage of controlled substance dispensed, ◦ Pharmacy that dispensed the prescription ◦ In some cases, the practitioner Assists in checking for potential drug interactions, patterns of misuse, potential diversion or abuse and generally to assist in determining the appropriateness in dispensing. For pharmacist access: http://pmp.pharmacy.state.mn.us/pharmacist-rxsentryaccess-form.html Rational Use 1. Reassure patients prescribed opioids or benzos are taking as directed, evidenced by positive results 2. Make sure not being misused Stockpiling or selling to unauthorized others Evidenced by negative results 3. Detect presence of illicit non-prescribed drugs Heroin, cocaine, non-prescribed opioids, etc. Tenore, P. Advanced Urine Toxicology Testing. Journal of Addictive Diseases, 2010;29:436448. Two types of tests used: 1. Immunoassay ◦ ◦ ◦ ◦ ◦ Classify drug as present or absent Any response above the cutoff is deemed positive Any response below the cutoff is negative Subject to cross-reactivity Some detect specific drugs, while others classes, i.e. opioids Gourly D, Helt H, Yale C. Urine Drug Testing in Clinical Practice: The Art and Science of Patient Care. Stanford, CT: California Academy of Family Physicians, PharmaCom Group, Inc; 2010. Immunoassay Pearls: Human urine has a creatinine concentration greater than 20 mg/dL. In the clinical setting it is important that 300 ng/mL or less be used for initial screening of opiates (Food stuff and poppy seed can make +); Confirm with laboratory test Opiate Class; lower sensitivity to hydromorphone , hydrocodone, oxycodone , oxymorphone, fentanyl, meperidine, and methadone Gourly D, Helt H, Yale C.

Urine Drug Testing in Clinical Practice: The Art and Science of Patient Care. Stanford, CT: California Academy of Family Physicians, PharmaCom Group, Inc; 2010. Immunoassay Pearls (continued): Amphetamine/methamphetamine are highly crossreactive ◦ may detect other ephedrine and pseudoephedrine ◦ Further testing may be required by a more specific method, i.e. GC Opiate class: morphine and codeine Ability of opiate immunoassays to detect semisynthetic/ synthetic opioids varies among assays because of differing cross-reactivity patterns. Specific immunoassay tests for some semisynthetic/ synthetic opioids may be available (eg, oxycodone, methadone). Gourly D, Helt H, Yale C. Urine Drug Testing in Clinical Practice: The Art and Science of Patient Care . Stanford, CT: California Academy of Family Physicians, PharmaCom Group, Inc; 2010. 2. GC/MS (Laboratory Testing) Generally, a more definitive laboratory-based procedure Identify specific drugs; may be needed: (1) Specifically confirm the presence of a given drug; i.e. morphine is the opiate causing the + IA response (2) to identify drugs not included in an immunoassay test (3) when results are contested.
