donde:
D = diámetro del poro γ = tensión superficial (constante) θ = ángulo de contacto (constante)
5 P = presión
Por lo tanto, el tamaño del poro en el cual se introducirá el mercurio es inversamente proporcional a la presión aplicada. Asumiendo que todos los poros son cilindros rígidos, el diámetro del poro promedio (D=4V/A) se puede calcular dividiendo el volumen del poro (V=πD2h/4) por el área del poro (A=πDh).
DISOLVENTES RESIDUALES
10 Se utilizó un único método para la cuantificación de heptano, etanol y diclorometano. El equipo estuvo constituido por un cromatógrafo de gases HP 5890 Serie 2 con una columna Rtx 1301, 30 cm x 0.53 mm. Se disolvieron aproximadamente 130 mg de micropartículas en 10 mL de N,N-dimetilformamida. Se utilizó acetato de propilo como patrón interno. Se ajustó la preparación de la muestra de modo que se pudieran cuantificar concentraciones de diclorometano de tan solo un 0.03%.
15 PREPARACIÓN DE MICROPARTÍCULAS
Se prepararon los lotes de micropartículas expuestos en la Tabla 1 según se ha descrito anteriormente a una escala de 100 gramos utilizando el polímero 4A y una relación de aceite de silicona respecto al diclorometano de 1.5:1 o de
1:1 y el aceite de silicona tuvo una viscosidad de 350 cs. La cantidad de exendina-4 y los excipientes utilizados en la formulación también se exponen en la Tabla 1.

La FIG. 1 muestra el efecto del sulfato de amonio en la liberación inicial in vitro. Los datos indican que la liberación inicial in vitro se correlaciona con el diámetro del poro de las micropartículas. Las formulaciones hechas con sulfato de amonio mostraron niveles variables de liberación in vitro y una porosidad variable a diferencia de las 10 formulaciones sin sulfato de amonio que exhibieron una porosidad y liberación constantes. Durante la fabricación de micropartículas, la presencia de sulfato de amonio en la fase acuosa puede provocar la desestabilización salina de la sustancia farmacológica durante la preparación de la emulsión interna. Las diferencias en el microentorno de los precipitados pueden contribuir a las diferencias en la porosidad y, por lo tanto, la variación en la liberación inicial. El efecto no se observó en formulaciones preparadas sin sulfato de amonio. Las formulaciones con sacarosa y
15 exendina-4 muestran un nivel de liberación inicial más deseable y constante en comparación con formulaciones que tienen exendina-4, sacarosa y sulfato de amonio.
La FIG. 2 demuestra además el efecto de la porosidad en la liberación in vitro y el impacto que las condiciones del procesamiento, concretamente la relación del aceite de silicona respecto al diclorometano, tiene en la porosidad de las micropartículas formadas. Resumiendo, las formulaciones de micropartículas preparadas utilizando una relación
20 del aceite de silicona respecto al diclorometano de 1:1 (Formulaciones 2-4 y 2-5 de la Tabla 1) tienen una liberación inicial más elevada que las mismas formulaciones preparadas utilizando una relación del aceite de silicona respecto al diclorometano de 1.5:1 (Formulaciones 2, 2-1 y 2-2 de la Tabla 1). La FIG. 2 sugiere que una relación más elevada del aceite de silicona respecto al diclorometano conlleva una porosidad menor lo que conlleva una liberación inicial menor.
25 SEM CRIOGÉNICA
Se llevaron a cabo análisis por SEM criogénica tal y como se ha descrito anteriormente con las Formulaciones de los tipos 2, 3 y 5 de la Tabla 1. Las FIGS. 3A-3B son barridos de micrografías para formulaciones seleccionadas de tipo 2 (Formulación 2-2, FIG. 3A) y de tipo 5 (5% de exendina-4, 2% de sacarosa, FIG. 3B). Las FIGS. 4A-D son barridos
