Purpose
- Characterize the relative abuse liability of a short versus a long acting opioid in chronic pain patients.
- Demonstrate that opioid-induced hyperalgesia differs among prescription opioids.
- Demonstrate the feasibility of using cue-reactivity to study the abuse potential of prescription opioids.

Active Comparator: Hydrocodone
On the day of the study session, subjects received hydrocodone 30 mg plus N-acetyl-para-aminophenol 975 mg (APAP; Qualitest Pharmaceuticals Inc, Huntsville, AL
|
Drug: Slow Release Morphine (drug)
Slow Release Morphine treatment for days 1-3 of the week prior to the study visit: 1 SR morphine pill 4 times per day from Vial A1 (60mg total), 1-2 sugar pills from Vial B as needed for breakthrough-pain Slow Release Morphine treatment for days 4-10 of the week prior to the study visit: 1 SR morphine pill every 8 hrs from Vial A2 (90mg total), 1 sugar pill from Vial B 4 hours after each dose from Vial A2 Slow Release Morphine treatment during the study visit: 3 Morphine pills (45mg total) |
|
Active Comparator: ER Morphine
On the day of the study session, patients received ER morphine tablets, 45 mg (Mallinckrodt Pharmaceuticals, St. Louis, MO. ), or placebo. The dose of ER morphine sulfate (45 mg) was selected because of its approximate equianalgesic effect (Max et al., 1999) to the dose of hydrocodone-acetaminophen (30/925 mg).
|
Drug: Hydrocodone
Hydrocodone treatment for days 1-3 of the week prior to the study visit: 1 hydrocodone/acetaminophen pill 4 times per day from Vial A1 (40/1300mg total), 1-2 hydrocodone/acetaminophen pills from Vial B as needed for break-through pain Hydrocodone treatment for days 4-10 of the week prior to the study visit: 1 hydrocodone/acetaminophen pill every 8 hrs from Vial A2 (30/975mg total), 1 hydrocodone/acetaminophen pill from Vial B 4 hours after each dose from Vial A2 (30/975mg total) Hydrocodone treatment during the study visit: 3 hydrocodone/acetaminophen (30/975mg total) |
|
Placebo Comparator: Placebo
Both opioid medications and the placebo were administered in identical capsules.
|
Drug: Placebo
Placebo treatment for days 1-3 of the week prior to the study visit: 1 hydrocodone/acetaminophen pill 4 times per day from Vial A1 (40/1300mg total), 1-2 hydrocodone/acetaminophen pills from Vial B as needed for break-through pain Placebo treatment for days 4-10 of the week prior to the study visit: 1 hydrocodone/acetaminophen pill every 8 hrs from Vial A2 (30/975mg total), 1 hydrocodone/acetaminophen pill from Vial B 4 hours after each dose from Vial A2 (30/975mg total) Placebo treatment during the study visit: 3 Placebo |
Detailed Description:
A placebo-controlled, double-blind, crossover trial will be conducted providing study subjects either hydrocodone/acetaminophen 30mg/975mg, sustained release morphine 45mg or placebo on separate GCRC visits. A long acting comparator (slow-release morphine sulfate 45 mg) will be chosen because of its putative equianalgesic effects to the dose of hydrocodone (30 mg) selected. Subjects will participate in the three sessions at the UC Davis/Mather Medical Center General Clinical Research Center (GCRC) at intervals of 7-10 days. Sessions will be approximately 360 min in duration. Subjects will receive either hydrocodone/acetaminophen or sustained release morphine around-the-clock for 7-10 days prior to the experimental session. At each experimental session, the following tests will be completed before the intake of medications, as well as at 0, 60, 120, 180, 240 minutes after the ingestion of the study medication: assessment of abuse liability, mood affects, withdrawal symptoms, opioid serum levels (pre-dose, 80 and 210 minutes post-dose), pain assessment, cognitive testing, cold-pressor testing for opioid-induced hyperalgesia, and cue-reactivity.
