Análisis potenciométrico de formulaciones farmacéuticas de Ciprofloxacina

Abstract

La ciprofloxacina, componente activo en la terapia del síndrome inflamatorio intestinal, es un antibiótico del grupo de las fluoroquinolonas. La Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (ANMAT) establece la técnica de HPLC con detección UV como método de referencia para cuantificar su contenido en comprimidos. Si bien la titulación potenciométrica de este fármaco con bases fuertes es insatisfactoria, el hidróxido de amonio facilita su cuantificación haciendo uso de la primera y segunda derivada de la curva. Por lo tanto, se propone una potenciometría indirecta haciendo uso de este titulante. Optimizado el método y aplicado a comprimidos de ciprofloxacina 500 mg es lineal en el rango de 0,7 a 1,5 mg/ml. Ensayos efectuados con placebo, indican que los excipientes no interfieren. La recuperación del principio activo es de 99,8- 100,2%. La precisión, expresada como repetibilidad, condujo a un CV de 0,45% y la precisión intermedia, para días y analistas diferentes, acusa CV< 2%. Los resultados son comparables en términos de exactitud y precisión (1es1 1 P< 0,05) a los del método de referencia.
