Objetivo: Estandarizar y validar un método sencillo, con alta eficacia y especificidad para la determinación de voriconazol.  Material y métodos: Para la cuantificación de voriconazol se empleó un equipo de cromatografía líquida de alta resolución Shimadzu, acoplado a un detector ultravioleta-visible diodo-array, realizando la separación cromatográfica con una columna Brisa LC2 C18. Las condiciones cromatográficas que se definieron fueron: temperatura de la columna, 35ºC; longitud de onda, 256 nm; volumen de inyección, 20 µl; flujo, 1,5 ml/min; tiempo de análisis, 9 min, fase móvil agua con ácido fórmico 0,5 % / acetonitrilo 65/35. Previo a la inyección cromatográfica, las muestras sufrieron un tratamiento consistente en la precipitación de proteínas con acetonitrilo y posterior centrifugación, inyectándose el sobrenadante. Se utilizó el programa estadístico SPSS v. 25, considerando una p&lt;0,05 como estadísticamente significativa.  Resultados: El método puesto a punto es selectivo y lineal (r2 =1), con un coeficiente de variación &#8804;5 %. En cuanto a la exactitud y la precisión los coeficientes de variación fueron &#8804; 5 %, cumpliendo así con los requisitos establecidos para el rango de concentraciones 0,1 µg/ml-10 µg/ml.  Conclusiones: La selectividad y la sencillez del tratamiento de muestra hacen de él un método eficaz, rápido y sencillo para la determinación de voriconazol en suero y con sensibilidad mayor al de los inmunoensayos utilizados.]]></p></abstract>

Objective: To standardize and validate a simple method with high efficacy and specificity for the determination of voriconazole.  Method: For the quantification of voriconazole, a Shimadzu high performance liquid chromatography equipment was used, coupled to an ultraviolet-visible diode array detector, performing the chromatographic separation with a Brisa LC2 C18 column. The chromatographic conditions defined were: column temperature, 35ºC; wavelength, 256 nm; injection volume, 20 µl; flow rate, 1.5 ml/min; analysis time, 9 min, mobile phase water with formic acid 0.5 % / acetonitrile 65/35. Prior to chromatographic injection, the samples underwent a treatment consisting of protein precipitation with acetonitrile and subsequent centrifugation, and the supernatant was injected The SPSS v. 25 statistical program was used, considering a p&lt;0.05 as statistically significant.  Results: The method developed is selective and linear (r2 =1), with a coefficient of variation &#8804; 5%. In terms of accuracy and precision, the coefficients of variation were &#8804; 5 %, thus complying with the requirements established for the concentration range 0.1 µg/ml-10 µg/ml.  Conclusion: The selectivity and the simplicity of the sample treatment make it an effective, fast and simple method for the determination of voriconazole in serum and with a higher sensitivity than the immunoassays used.]]></p></abstract>
