Brief Summary
Objective is to evaluate the pharmacokinetics profile of hydrocodone's metabolite hydromorphone in patients who are taking hydrocodone on a routine basis for more than 3 months for chronic pain and correlate hydromorphone levels to their hydrocodone usage.

Outcome Measures
Primary Outcomes (1)
Peak Plasma Concentration of Hydromorphone
Determine the plasma pharmacokinetic profile of hydromorphone in chronic pain subjects taking hydrocodone within a 6 hour time frame. Note: Sensitivity of the lab test used to determine plasma hydromorphone concentrations was not sufficient. Failure to meet the lowest level of detection, all subjects plasma hydromorphone concentrations were recorded as zero at all time points.
Up to 6 hours
Secondary Outcomes (2)
Correlation of Plasma PK of Hydrocodone
1 Month
Peak Urine Concentration of Hydromorphone
Up to 4 hours
Study Arms (2)
Group 1
EXPERIMENTALBlood will be drawn at 0, 1, 3, and 5 hours after taking one dose of hydrocodone/APAP. Urine will be taken at hour 0 and 3.
Group 2
EXPERIMENTALBlood will be drawn at 0, 2, 4, and 6 hours after one dose of hydrocodone/APAP. Urine will be taken at hour 0 and 4.
Interventions
Dose: Standard prescribed dose Frequency: Once Duration: Once
Eligibility Criteria
You may qualify if:
- Man or woman aged 18-75
- Documented clinical diagnosis of chronic pain.
- Have been taking hydrocodone/APAP for their chronic non-cancer pain.
- Subjects currently on hydrocodone/APAP must be taking minimal daily dose of 15mg of Hydrocodone for at least 30 days.
- Subjects must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.
You may not qualify if:
- Subjects who are taking concomitant medications or Nutraceuticals that interfere with Hydrocodone metabolism as listed in Appendix 11 and/or as deemed clinically significant by a pharmacovigilance team that is contracted to monitor and advise.
- Health concerns that the study physician feels may confound study results.
- Individuals who are cognitively impaired or who are not able to give informed consent.
- Previous participation in a clinical research trial within 30 days prior to randomization.
- The subject has an ongoing abuse of illicit substances, alcohol, or actively smoking marijuana.
