NCT01395784

Brief Summary

The ability of pioglitazone (PIO) to alter the effects of opioids in humans has not been characterized in a controlled laboratory setting. Accordingly, the proposed investigation seeks to examine the effects of PIO on oxycodone, one of the most commonly used and abused opioid drugs in the U.S. (Davis et al., 2003). More specifically, the primary aim of this investigation is to characterize the subjective effects of oxycodone under maintenance on various doses of PIO (0, 15, and 45 mg) in non-dependent, prescription opioid abusers. Secondary aims of the study are to examine the influence of PIO on the analgesic, cognitive, and physiological effects of oxycodone.

Outcome Measures

Primary Outcomes (1)

  • Subjective Ratings of "Good" Drug Effect

    Visual analog scale ratings (0-100 mm scale, 0=Not at all, 100=Extremely)

    Measured during the lab session conducted at the end of each maintenance period

Secondary Outcomes (1)

  • Analgesic Responses Using the Cold Pressor Test

    Measured during the lab session conducted at the end of each maintenance period

Study Arms (3)

Placebo Maintenance Period

PLACEBO COMPARATOR

Participants will complete the various outcome measures following a 2-3 week maintenance period on Placebo (PCB).

Drug: pioglitazone

PIO 15 Maintenance Period

EXPERIMENTAL

Participants will complete the various outcome measures following a 2-3 week maintenance period on Pioglitazone (PIO) 15 mg.

Drug: pioglitazone

PIO 45 Maintenance Period

EXPERIMENTAL

Participants will complete the various outcome measures following a 2-3 week maintenance period on Pioglitazone (PIO) 45 mg.

Drug: pioglitazone

Interventions

A PPARγ agonist, also marketed as Actos. Participants will be maintained on ascending doses of Placebo, pioglitazone 15 mg and 45 mg, prior to completing a lab session at the end of each dosing period.
