Drug usage in southern Brazilian hospitals

A drug usage survey was carried out in 14 hospitals in the southernmost region of Brazil in the year 1979. The average number of drugs prescribed per patient was 8.6, and antimicrobials, followed by analgesics, vitamins and sedatives-tranquilizers were the most often employed drug categories. Among the antimicrobials, ampicillin was the first, followed by chloramphenicol, but the overall leading drug was an analgesic-antipyretic, dipyrone. Some possible distortions in drug usage are discussed.
