Trial Outcomes & Findings for Creatine as a Treatment Option for Depression in Methamphetamine Using Females (NCT NCT01514630)

NCT ID: NCT01514630

Last Updated: 2015-06-29

Results Overview

Eight weeks of oral creatine supplementation will result in improvements in Hamilton Depression Rating Scale (HAMD) in female methamphetamine users. HAMD scoring is based on 17 items. Minimum score is 0 and maximum 52. A score of 0-7 is considered to be normal. Scores of 20 or higher indicate moderate or severe depression. 0-7 = Normal 8-13 = Mild Depression 14-18 = Moderate Depression 19-22 = Severe Depression ≥ 23 = Very Severe Depression

Measure
Creatine Monohydrate
14 female depressed methamphetamine users received 5 grams of creatine monohydrate daily for eight weeks. Participants were seen twice weekly after creatine was initiated. All participants met SCID-I/P criteria for lifetime methamphetamine dependence or for current methamphetamine dependence. After consent was obtained, the principal investigator administered the SCID-I/P and HAMD, and if a female met SCID-I/P criteria and scored \> 15 on the HAMD, the following additional screening data were collected: Beck Anxiety Inventory, C-SSRS , vital signs, concomitant medications, self-report drug use over the past 48 hours for cigarettes, alcohol, cocaine, methamphetamine, marijuana, heroin and prescription controlled substances, urine drug screen for methamphetamine, opiates, benzodiazepines, marijuana and cocaine, pregnancy testing and attendance in outpatient treatment and/or 12 step programs.
