Sievers, ANVISA Workshop Brasilia 29 Sep 2015 42 INSTRUÇÃO NORMATIVA Nº 4, 18 JUNHO 2014 2.9 VALIDAÇÃO DE MÉTODOS ANALÍTICOS Revalidações As metodologias analíticas devem ser revalidadas em caso de mudanças significativas na obtenção ou composição da matériaprima, mudanças na composição do produto acabado ou mudanças no procedimento analítico. Dependendo do grau de alteração realizada, apenas uma validação parcial (incluindo seletividade, exatidão e precisão) será suficiente. A empresa deve apresentar argumentos técnicos que justifiquem essa medida. H. Sievers, ANVISA Workshop Brasilia 29 Sep 2015 43 Summary and Conclusion The specification does not describe/define an herbal API in its totality because herbal API are strongly defined by their production process starting with the cultivation/collection of plant material. Thus, a change of the extract manufacturer is a major variation with potential influence on quality, safety and efficacy and thus requires thorough assessment and documentation of quality of plant material (identity, contaminants, composition) manufacturing process final composition of the preparation (incl. excipients) content of markers (and toxic compounds where applicable) analytical methods for herbal drug and API H. Sievers, ANVISA Workshop Brasilia 29 Sep 2015 44 Summary and Conclusion Exchange of the extract manufacturer may potentially affect most parts of module 3.2.S of the dossier or the relevant chapters and information according to INSTRUÇÃO NORMATIVA Nº 4, 18 JUNHO 2014, respectively.
