Implementation of a Spectrofluorimetric Method to the Determination of 8-Methoxypsoralen in Capsules and Creams Used in Treatment of Psoriasis and Vitiligo: an Evaluation of the Quality of Compounding Pharmacies in Rio de Janeiro
Abstract:8-Methoxypsoralen is a widely sold drug in Brazil as handled capsules and creams because it is only industrially available as soft gel capsules of 10 mg. In order to contribute to the quality control of these pharmaceutical forms, a spectrofluorimetric method was implemented and applied for the evaluation of the quality of compounding pharmacies in the state of Rio de Janeiro (Brazil). Solutions of 8-methoxypsoralen prepared in ethanol/water (30:70 v/v) produced fluorescence signals at excitation/emission wave… Show more
