Determinação do teor de cálcio em comprimido à base de lactato de cálcio utilizado no tratamento da osteoporose

Abstract: Recebido em 20/9/11; aceito em 9/3/12; publicado na web em 2/7/12 DETERMINATION OF CALCIUM IN CALCIUM LACTATE TABLETS USED IN THE TREATMENT OF OSTEOPOROSIS.The present study utilized thermogravimetry (TG) and optical emission spectrometry with inductively coupled plasma (ICP/OES) to determine the amount of calcium in calcium lactate tablets used in the treatment of osteoporosis. Thermogravimetry results indicated that the decomposition temperature of CaCO 3 occurred at 603.9 and 609.4 o C in the samples of cal… Show more

“…Worldwide, approximately 30% of women and 10% of men over 50 years of age are affected by osteoporosis. In the United States, osteoporosis affects 55% of the population in this age group (Schröder et al, 2012;Meneses et al, 2012) and in Brazil it has been estimated that 10 million people suffer from this disease (Souza et al, 2012). The main consequence of osteoporosis is the occurrence of fractures and their ensuing complications.…”

“…Thermal analysis refers to a group of techniques in which a property of the sample is measured against time or temperature, whereas the temperature of the sample, in a specified atmosphere, is heated or cooled at fixed rate of temperature change or hold at constant temperature (Giron, 2002). The differential scanning calorimetry (DSC) and the thermogravimetric analysis (TG) are the most used analytical techniques in the development of different studies on a wide variety of pharmaceutical materials (Souza et al, 2012). Thermal analysis methods, especially DSC and TG, have been used to feature the study, development and quality control of medications in general (Shamsipur, 2013).…”
