Methods Tests were done to confirm the identity and concentration of the active ingredient and determine the pH, homogeneity, volume and organoleptic characteristics of the oral suspensions. Quantification of the active ingredient showed precision, accuracy, linearity and specificity. Results The active ingredient concentrations were below the pharmacopeial specifications in samples B, C and E, and above in sample F. Moreover, the pH of samples C, E and F were outside the specification limits. Samples C and E were not sufficiently homogeneous. The volumes of most samples were in agreement with the volumes reported on the labels, except for sample C. Conclusion The results show that better surveillance by the relevant agencies is needed to ensure patient safely and the quality of compounded drugs.Acesso AbertoCromatografia líquida de alta pressãoNaproxenoPreparações farmacêuticasarticlehttps://doi.org/10.24220/2318-0897v21n1/6a1876
