Abstract
Microesferas farmacéuticas, caracterizadas porque contienen,como principio activo, una mezcla de ácido valproico y una de sus sales farmacéuticamente aceptables, en asociación con un soporte matricial elegido entre ésteres de glicerol, aceites hidrogenados, polietilenglicoles esterificados o ceras y sus mezclas. 1Procedimiento para la preparación de microesferas farmacéuticas según alguna de las reivindicaciones 1 a 18, caracterizado porque: - se agrega ácido valproico y la sal farmacéuticamente aceptable de este ácido al soporte matricial fundido y se mantiene bajo agitación la mezcla restante hasta la obtención de un fluido limpio, - se fuerza la mezcla en forma límpida así obtenida, a través de una tobera sometida a vibración, lo que origina la formación de gotitas al salir de la tobera y son acarreadas por gravitación a una torre en la cual circula a contracorriente un gas frío, - se recogen las microesferas en la base de la torre.
