OBJECTIVES: To investigate the prescription and dispensation of psychotropic medications through the analysis of the prescriptions/notices kept at various institutions in two cities in the state of São Paulo. METHODS: The prescriptions kept at drugstores, magistral pharmacies, primary care settings and hospitals were collected and analyzed in collaboration with the Sanitary Vigilance agencies in the year of 1999. The information in the prescriptions/notices were typed and tabulated. RESULTS: A total of 108,215 prescriptions were processed, being 76,954 for benzodiazepines, 26,930 for anorexigenic drugs, 3,540 for opiates and 788 for other drugs. The benzodiazepines most frequently prescribed were: diazepam (31,644), bromazepam (16,911) and clonazepam (7,929). Among the anorexigenic drugs, diethylpropion (14,800) and femproporex (10,942) were the most common. When compared to men, women were given more prescriptions, mainly for anorexigenic drugs: the ratio was 10:1 in the prescriptions for diethylpropion and femproporex. The few magistral pharmacies (n=6) handled even more prescriptions than did the drugstores (n=49). A number of errors and inconsistencies were detected in the prescriptions analyzed. CONCLUSIONS: The results confirm the occurrence of an irrational use of such medications and a series of inadequate practices related to their prescription in Brazil. Therefore, they point out to the need of a comprehensive review of the government's control system of these substances.
The authors studied the acute effects of "Guaraná", when compared to caffeine and placebo, (double blind study) on cognition, anxiety and sleep in 30 normal volunteers. Although results were negative it cannot be concluded that "Guaraná" is harmless. Other studies shall be undertaken, administering "Guaraná" on a long term basis, as popularly proclaimed.
Paulinia cupana (guarana) is a Brazilian plant given great prestige in popular medicine, for example as being a potent stimulator of brain functions. The authors assessed the effects of the long-term administration of guarana on the cognition of normal, elderly volunteers. Forty-five volunteers were studied, with a random distribution in three experimental groups: placebo (n = 15), caffeine (n = 15), and guarana (n = 15), in a double-blind study. There were no significant cognitive alterations in these volunteers.
The use of Ecstasy in Brazil has gained visibility in recent years. Nevertheless, scientific data on this issue remain scarce. The present study focused on clarifying this phenomenon by means of qualitative and ethnographic research. Observational studies (N = 8), information obtained from key informants (N = 14) and interviews with Ecstasy users (N = 32) from the city of São Paulo were part of this study. The results pointed to night clubs and rave parties where electronic music is played as the main context of use. Interviews with users revealed a sample of young adult members of the highest layers of society, with a good educational background and access to the labor market. Furthermore, polydrug use was manifested. Users' typology was established regarding the pattern of drug use, showing two profiles of users: the "Rave Generation," consisting of more recent users who initiated this use with the arrival of the large-sized rave parties at the end of the 1990s. The second profile, the "Sons of the Hell's Club," consisted of more experienced users (beginning in the early 1990s) and showed a richer history of use. Neither profile group had sought help regarding their Ecstasy use, and both showed positive beliefs related to the safety of use.
