Arm Description

Patients will take oral N-acetylcysteine 900 mg/day for 1 week, 1800 mg/day for 1 week, 2700 mg/day for 1 week, and then 3600 mg/day.

Patients will take oral placebo (identical matching placebo) during the study period.

Outcomes

Primary Outcome Measures

Alcohol Consumption (Percentage of Heavy Drinking Days)
The percentage of heavy drinking days was primary a priori outcome measure. Heavy drinking was defined as ≥ 5 standard drinks per day for men and ≥ 4 standard drinks for women. One standard drink is any drink containing about 0.6 fluid ounces or 14 grams of pure alcohol. The percentage of heavy drinking days (HDD) was measured at each weekly visit during the 8 weeks--from week 1 (before starting intervention) to week 9 (after completing intervention). At each week, the percentage of HDD was calculated during the period (usually 7 days) since the last previous visit.

Secondary Outcome Measures

The Penn Alcohol Craving Scale
Alcohol craving was secondary a priori outcome measure. Alcohol craving was measured at each weekly visit during the 8 weeks--from week 1 (before starting intervention) to week 9 (after completing intervention). The Penn Alcohol Craving Scale is a self-rated scale designed to assess alcohol craving. The score range of the Penn Alcohol Craving Scale is between 0 and 30, with 30 assigned to the highest (worst) alcohol craving.
The Obsessive Compulsive Drinking Scale
Alcohol craving was secondary a priori outcome measure. Alcohol craving was measured at each weekly visit during the 8 weeks--from week 1 (before starting intervention) to week 9 (after completing intervention). The Obsessive Compulsive Drinking Scale is a self-rated scale designed to assess alcohol craving. The score range of the Obsessive Compulsive Drinking Scale is between 0 and 56, with 56 assigned to the highest (worst) alcohol craving.
