Trial Outcomes & Findings for Cocaine/Crack and Reduction of Compulsion With Biperiden (NCT NCT01251393)

NCT ID: NCT01251393

Last Updated: 2020-10-14

Results Overview

The patients answered the Minnesota Cocaine Craving Scale (Halikas et al., 1991). INTENSITY: Evaluation of crack strength by cocaine in the previous week: Zero (no craving)---------------------------- -----10 (Intense craving) Ranges from 0 to 10 (zero = no craving; 10 intense craving). Using a rule starting from 0, we determine the number that corresponds to the compulsion. The farther from 0 the more intense the compulsion will be. Frequency of craving onset: How many times a day 0 time/day - check: 0 point 1. time/day - check: 1 point 2. times/day - check: 2 points 3. to 5 times/day - check: 3 points 6 to 10 times/day - check: 4 points 11 to 20 times/day - check: 5 points more than 20 times/day - check: 6 points Ranges from 0 to 6 points (zero = no craving; 1-2 points: Light; 3-4 points: moderate; 5- 6: intense craving). The sum of the points of the subscales provides the final score.

PRIMARY outcome

Timeframe: 3 months

Population: A total sample of 166 patients was evaluated during the project. Of that number, 55 did not fulfil the inclusion criteria. The main reasons for exclusion were the presence of clinical comorbidities (active hepatitis, tuberculosis under treatment and epilepsy) or psychiatric comorbidities.

The patients answered the Minnesota Cocaine Craving Scale (Halikas et al., 1991). INTENSITY: Evaluation of crack strength by cocaine in the previous week: Zero (no craving)---------------------------- -----10 (Intense craving) Ranges from 0 to 10 (zero = no craving; 10 intense craving). Using a rule starting from 0, we determine the number that corresponds to the compulsion. The farther from 0 the more intense the compulsion will be. Frequency of craving onset: How many times a day 0 time/day - check: 0 point 1. time/day - check: 1 point 2. times/day - check: 2 points 3. to 5 times/day - check: 3 points 6 to 10 times/day - check: 4 points 11 to 20 times/day - check: 5 points more than 20 times/day - check: 6 points Ranges from 0 to 6 points (zero = no craving; 1-2 points: Light; 3-4 points: moderate; 5- 6: intense craving). The sum of the points of the subscales provides the final score.
