Condition(s) targeted: Nicotine Dependence

Intervention: Intravenous Nicotine (Drug); Progesterone (Drug)

Phase: N/A

The proposed clinical studies will analyze the interactions between progesterone, nicotine, alterations in 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

Clinical Details

Official title: Effects of Progesterone on IV Nicotine-Induced Changes in Hormones and Subjective Ratings of Stimulant Drug Effect

Study design: Allocation: Non-Randomized, Endpoint Classification: Pharmacokinetics/Dynamics Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator)

Primary outcome: Effects of Progesterone on IV nicotine hormones and mood

Detailed description: These clinical studies are designed to examine the effects of progesterone on IV nicotine induced changes on anterior pituitary (ACTH, LH, and Prolactin) and adrenal hormones (DHEA and cortisol). We also plan to study norepinephrine (NE) and epinephrine (E), because nicotine stimulates rapid release of NE and E in preclinical and clinical studies. The study will examine the acute effects of progesterone on the effects of IV nicotine on the HPG axis. Progesterone's influence on the acute effects of nicotine on the gonadal steroid hormones (estradiol, testosterone, progesterone) are unknown. The effects of progesterone on nicotine induced changes on gonadal steroid hormones and the reciprocal feedback regulation by LH will also be examined. The temporal covariance of progesterone influenced hormonal changes with serum nicotine levels and nicotine-induced changes in subjective states and cardiovascular measures will be analyzed. Finally, the covariance between the effects of progesterone on nicotine-induced changes in endocrine, subjective and cardiovascular effects and the temporal concordance with increases in serum nicotine and cotinine levels will be determined.


Minimum age: 18 Years. Maximum age: 40 Years. Gender(s): Female.


Inclusion Criteria:

- Women between the ages of 18 and 40 who currently smoke at least 15 cigarettes every

day, and who fulfill DSM-IV diagnostic criteria for nicotine dependence will be eligible for participation.

- No evidence of clinically significant disease based upon complete medical history and

physical examination supervised by Dr. Arthur Siegel (Chief of Internal Medicine).

- Absence of DSM-IV Axis I Disorders other than nicotine dependence (305. 10) as

measured by the Structured Clinical Interview (SCID).

- Routine laboratory blood tests including complete blood count, electrolytes, BUN and

creatinine, liver function tests, hepatitis panel and urinalysis will be performed. Laboratory parameters must be within the normal range. HBsAg must be negative but subjects who have hepatitis serology consistent with previous exposure to Hepatitis A, Hepatitis B, or Hepatitis C, but who do not have clinical and biochemical evidence of acute infection, will be acceptable.

- Hematocrit levels ≥ 35% for females.

- Serum pregnancy test (hCG beta subunit) results must be negative within 24 hrs of the

study session day.

- Normal EKG.

- A Body Mass Index (BMI—ratio of weight (W) to height (H) squared; W/H2=kg/m2) of

between 18. 0 and 27. 0 for women.

- Subjects must be able to read and understand instructions, as well as provide a valid

informed consent. Exclusion Criteria:

- Participants with any lifetime DSM-IV Axis I disorder other than nicotine dependence.

- Participants with clinically significant medical disorders.

- Women who are pregnant as determined by laboratory testing for serum beta hCG.

- Women who use hormonal contraceptive medications will not be accepted, because this

would confound the hormonal measures.

- Women with a mean BMI of outside the range 18. 0-27. 0.

- Subjects with peanut/peanut oil allergies will be excluded.

- Participants diagnosed with lactose intolerance will be excluded.

- Participants who describe themselves as seeking treatment will not be selected but

will be referred to local smoking cessation programs.
