Avaliação do uso de benzodiazepínicos pelos usuários da unidade básica de saúde do município de Camacho - MG pela dispenção realizada na farmácia básica do SUS

Abstract

Benzodiazepines (BDZ's) are psychotropic medications used worldwide to treat anxiety and insomnia. Because of their low cost and easy access to public health, Diazepam and Clonazepam are commonly prescribed by general practitioners, often inappropriately, leading to the risk of abuse. This study aimed to identify a possible misuse of these drugs by the population of Camacho (MG) and the profiles of users, through secondary data analysis of pharmacy dispensing the municipal primary in 2008. In order to quantify this, a methodology from World Health Organization (WHO) was applied, through the system called Anatomical Therapeutic Chemical / Defined Daily Dose (ATC / DDD), which classifies and measures the amount of drugs consumed in a given period and place, allowing comparisons between population groups. It was found that in Camacho, in 2008, for each 1000 inhabitants 41.36 used 10mg of Diazepam per day. And also to 9.56 per 1000 population used 2mg of Clonazepam per day. We found 134 users for the first and 141 for the second, with no simultaneous use of them. Patients were predominantly female and aged between 40 and 59 years for both. The dispensation for the elderly was significantly lower than the adult population. As the place of residence, the majority of users lived in urban Diazepam, unlike Clonazepam, which was predominantly rural population. The duration of use ranged from 6 to 12 months, characterizing the chronic use. The data obtained for Camacho, compared to the literature, showed that consumption of BZD's in the city was above the national average in 2008. Due to the lack of a structured service for mental health care in the city, the prescriptions of these drugs are made by the physician of Family Health, either as indicated herein as pre-maintenance requirements, considering the high staff turnover. This highlights the need for further studies, more detailed about the use of BZD in Camacho, to enable the development of actions aiming to control it, and responsible practices.
