Effects of Progesterone on IV Nicotine Induced Changes on BOLD fMRI Signal, Hormones and Subjective Ratings of Stimulant Drugs

NCT01589068 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

No results posted yet for this study

Summary

The proposed clinical studies will analyze the interactions between progesterone, nicotine, fMRI measures of patterns of brain activity, covariance with endocrine hormones, mood and cardiovascular measures. It is hypothesized that the administration of progesterone at a dose that mimics luteal phase levels in normal cycling women will diminish the positive subjective effects of nicotine, as has been consistently observed for cocaine. This novel approach could have direct implications for facilitating smoking cessation treatment in women of reproductive age

Conditions

  • Nicotine Dependence

Interventions

DRUG

Intravenous Nicotine

Subjects will be given an IV challenge dose of nicotine or placebo in a constant volume of 2 mL on any study day. The nicotine solution (1.0 mg/70kg or 1.5 mg/70kg or 2.0 mg/70kg) will be administered over 1 min. This rate of drug delivery (2 mL over one minute) has been safe in our IRB-approved studies of nicotine. Most investigators have administered nicotine over 10 seconds without any adverse reactions. We concur with the IRB recommendation that the lower doses (1.0 mg/70kg and 1.5 mg/70 kg) will be administered first and the higher dose (2.0 mg/70kg) will be administered last.

DRUG

Progesterone

To stimulate the luteal phase of the menstrual cycle, Prometrium capsules containing 200 mg of micronized progesterone or placebo (lactose containing) capsules will be administered orally at 120 minutes before the injection of IV nicotine.
