Backgound:

Benzodiazepines constitute a depressant drugs group of Central Nervous System, used as anxiolytics, hypnotics, muscle relaxants and anticonvulsants. Consuming alcohol or associating them with other substances can cause significant toxicological interactions. As a prolonged use can cause disturbances and lead into dependence and tolerance to these.

Objective:

To determine benzodiazepines prevalence and its analogs in a sample of population served in the Navy Laboratory in San Fernando during the years 2013, 2014 and 2015.

Material and methods:

A descriptive transversal retrospective study. It was made, and was completed with the personal attended during the years 2013-2015. The variables were sex and Benzodiazepines or analogues consumed seven days before. We have used for the identification of substances listed at the ATC (Anatomical Therapeutic Chemical Classification System) classification of WHO.

Results:

In 2013, 138 had used benzodiazepines or analogue (In seven had consumed two benzodiazepines). In 2014 they had used benzodiazepines 130 (six had consumed two) and 2015 was observed in 169 (of which 13 had consumed two and one had consumed three benzodiazepines).In 2013 the prevalence was of 1,8%, with it was a 3,4% women and 1,6% men. In 2014 the global prevalence was of 1,9%, with it was a 5,2% women and 1,5% men. In 2015 the global prevalence was of 2,4%, with it was a 5,9% women and 2,1% men. Benzodiazepines most consumed in 2013 are Diazepam (39%), Tetrazepam (17%) and Alprazolam (16%). A 44% of Diazepam in 2014, a 25% of Alprazolam and a 9 % of Bromazepam. In 2015 of Diazepam were a 44%, a 22 % of Alprazolam and a 13% of Bromazepam.

Conclusions:

As in national surveys, consumption is higher in woman than in men. It is also observed a progressive increase in consumption in both groups over the analyzed years, although the prevalence in our study was lower.
