Abstract

Un liposoma para su uso en fármaco terapéutico o administración génica por administración pulmonar, en el que la superficie del liposoma está modificada con un poli(alcohol vinílico) hidrofobizado terminal.

Description

Ejemplo 2 (Ejemplo de referencia)
Preparación de liposoma modificado con quitosano
Se preparó un liposoma modificado con quitosano de la misma manera que en el Ejemplo 1, excepto que se usó quitosano (peso molecular: 150.000, grado de desacetilación: 85 %) en lugar del poli(alcohol vinílico) hidrofobizado
5 terminal. Sin embargo, el diámetro de partícula aumentó mezclando una cantidad igual de una suspensión de liposomas y tampón que contenía quitosano disuelto en el mismo, y por lo tanto se realizó un tratamiento ultrasónico después de mezcla.
Ejemplo de prueba 1
Evaluación del comportamiento intrapulmonar en ratas
10 El liposoma modificado con polímero del Ejemplo 1 o 2 (Ejemplo de referencia) se administró por vía transbronquial ((15,63 µg de CA/rata) a ratas Wistar macho (7 semanas de edad). Cinco horas después de la administración, se calculó la relación residual de dosificación (% de dosis) midiendo la concentración de CA en tejido pulmonar, fluido de lavado broncoalveolar (BALF) y células de lavado broncoalveolar (BALC) usando un espectrofluorómetro (HITACHI F3010). Para comparación, se realizó una prueba de la misma manera a la anteriormente descrita,
15 excepto que se usó un liposoma que no está modificado con un polímero (la composición de membrana y el contenido de CA son los mismos que en el Ejemplo 1) en lugar del liposoma modificado con polímero (Ejemplo comparativo 1). Los resultados se muestran en la Fig. 1.
Como es evidente a partir de los resultados mostrados en la Fig.1, en el liposoma modificado con polímero del Ejemplo 1, se detectó una fluorescencia más fuerte derivada de CA en BALF en comparación con el Ejemplo
20 comparativo 1. Así, se confirmó que el liposoma modificado con polímero del Ejemplo 1 es útil para ejercer una acción farmacológica en la superficie o las células de superficie de tejido pulmonar, ya que son capaces de retenerse en la superficie de tejido pulmonar durante un largo periodo de tiempo.
En el liposoma modificado con polímero del Ejemplo 2 (Ejemplo de referencia), se mostró que se transfirió más liposoma en el tejido pulmonar debido a que se observó una fluorescencia más fuerte derivada de CA en el liposoma
25 modificado con polímero del Ejemplo 2 (Ejemplo de referencia) en comparación con el Ejemplo comparativo 1. Por lo tanto, se reveló que el liposoma modificado con polímero del Ejemplo 2 (Ejemplo de referencia) puede ser transferido de manera eficiente en tejidos pulmonares en un corto tiempo, y así es posible administrar de manera eficiente en tejido pulmonar fármacos que, por ejemplo, no son fácilmente transferidos en el tejido pulmonar.
