Title in Portuguese
Desenvolvimento e validação de método analí­tico indicativo de estabilidade por CLAE-DAD-CAD para besilato de anlodipino e seus produtos de degradação
Keywords in Portuguese
Anlodipino
CL
Corona CAD
Abstract in Portuguese
O presente estudo foi realizado com o objetivo de se desenvolver e validar uma metodologia analítica indicativa de estabilidade para separação e quantificação de anlodipino e seus produtos de degradação no medicamento besilato de anlodipino 5 mg por comprimido. Para tanto, realizou-se um estudo de degradação forçada, como forma de identificar os principais produtos de degradação, que podem vir a formar num estudo de estabilidade, bem como estabelecer possíveis rotas de degradação. Foi utilizada a técnica instrumental de separação, cromatografia a líquido (CL), com dois tipos de detectores: arranjo de diodos (DAD) e corona CAD (Detector de aerossol carregado), coluna cromatográfica Zorbax SB-Phenyl 1,8µm 4,6 x 50 mm Agilent® e fase móvel constituída por tampão pH3,0, metanol e acetonitrila sob condições de gradiente (75% de tampão pH 3,0, 15% de metanol e 10% de acetonitrila; no tempo de 10 minutos tem-se 20% de tampão pH3,0, 60% de metanol e 20% de acetonitrila; no tempo de 13 minutos tem-se 75% de tampão pH3,0, 15% de metanol e 10% de acetonitrila; e no tempo de 15 minutos tem-se 75% de tampão pH3,0, 15% de metanol e 10% de acetonitrila); fluxo de 1,0mL/min até 10 minutos; de 10,1 a 13 minutos tem-se fluxo de 0,5 mL/min; e de 13,1 a 15 minutos volta ao fluxo de 1,0 mL/min; e detecção em 238 nm. O método apresentou-se linear, preciso, exato, robusto e seletivo, e proporcionou resultados confiáveis, sem interferência de degradantes e impurezas.

Abstract in English
This study was conducted in order to develop an analytical methodology indicative of stability for separation and quantification of the antihypertensive amlodipine and its degradation products in the drug amlodipine besylate 5 mg per tablet. For this development was performed a forced degradation study, in order to identify the main degradation products that may form in a stability study, as well as establish possible degradation routes. It was used the instrumental separation technique, liquid chromatography (LC) with two types of detectors: diode array (DAD) and corona CAD (Charged Aerosol Detector), chromatographic column Zorbax SB-Phenyl 4.6 x 50 mm 1,8µm Agilent® and mobile phase of buffer pH3,0, methanol and acetonitrile under gradient conditions (75% buffer pH3,0, 15% methanol and 10% acetonitrile; 10 minutes has 20% buffer pH3,0, 60% methanol and 20% acetonitrile; 13 minutes has become 75% of buffer pH3,0, 15% methanol and 10% acetonitrile; and 15 minutes has become 75% of buffer pH3,0, 15% methanol and 10% acetonitrile); flow 1.0 mL/ min up to 10 minutes; a flow 0,5 mL/min is obtained from 10,1 to 13 minutes; and from 13,1 minutes the flows returns to 1,0 mL/min; and detection in 238 nm. The method is linear, precise, accurate, robust and selective, and provided reliable results without interference from degradation products and impurities.
