Despite the aforementioned, and that this particular manifestation becomes more frequent among those affected, the mechanism, the approach and finally the prognosis that can be offered to the patient are still not clear....

The analytical method validation is an integral part of the quality control system, since it gives reliability to the analytical results obtained in a laboratory, to ensure that a drug comply established equality parameters. We present the validation of an analytical method for quantification of 2 mg Risperidone tablets, using the technique of spectrophotometry UV / VIS proposed by the authors G. Alagumanivasagam, A. Anton Smith, Department of Pharmacy, Annamalai University in India.For the analysis of 2 mg Risperidone tablets from three pharmaceutical laboratories (Farmindustria, Marfan and Medrock) methanol was used as solvent and was measured at a wavelength of maximum absorbance of 278 nm.The samples were subjected to acid degradation, alkaline oxidation and thermolysis, obtaining interference less than 2%. The linearity test method showed a correlation coefficient of 0.9998910. For ...
