Análise da capacidade volumétrica das vidrarias usadas na manipulação de medicamentos e suas consequências.

Abstract

The market offers a number of different grades of glass bottles used in the handling of magistral drugs, and which it isn't always used properly, in which not always used properly, which may cause measuring errors and, consequently, reproducibility of pharmaceutical form manipulated. Incorrect handling can result in pharmaceutical form of doubtful character and products with reduced effects of the active principle of or durability of the stability. The study search an exploratory analysis of graded glassware (graduated pipettes 1 and 2 ml, calyx of 60 ml and graded tube 10 and 100 mL) produced according to the volume specified to the rules specified for American Society by Testing and Materials (ASTM), comparing the results with the standards established by the Pharmacopoeia. The volumes were measured by determining the mass of water contained in the volume taken and, respectively, converted in volume through the density. Knowledge of glassware used for yield of medicines is important for the quality of the pharmaceutical form manipulated in pharmacy laboratory of the Federal University of Campina Grande, and thus, achieve the reduction of measurement errors and their consequences.
