Abstract

UNA MICROESFERA DE LIBERACION SOSTENIDA PRODUCIDA ENCERRANDO UN ANTIPSICOTICO HIDROFOBICO TAL COMO BROMOPERIDOL O HALOPERIDOL EN UNA BASE QUE COMPRENDE UN POLIMERO BIOCOMPATIBLE TAL COMO ACIDO POLILACTICO O UN COPOLIMERO DE ACIDO LACTICO/ACIDO GLICOLICO. PUEDE EXHIBIR UN DESEADO EFECTO FARMACOLOGICO, DONDE ES NECESARIA UNA ADMINISTRACION DE LARGA DURACION, INYECTANDO DE 1 A 8 SEMANAS, UNA VEZ POR SEMANA, EN LUGAR DE CADA DIA. COMO UN RESULTADO, PUEDE SER ESPERADA UNA IMPORTANTE MEJORA EN LA TOLERANCIA DURANTE TERAPIA SOSTENIDA. ADICIONALMENTE, EL USO DEL POLIMERO BIOCOMPATIBLE SIRVE PARA DISTRIBUIR INTEGRAMENTE CON OPERACIONES QUIRURGICAS TALES COMO IMPLANTACION, FACILIDADES HIPODERMICAS E INYECCION INTRAMUSCULAR JUSTO COMO EL CASO DE INYECCION PROLONGADA, Y SE PUEDE DISPENSAR CON EXTRACCION DE LA MICROESFERA. ADEMAS, LA MICROESFERA PUEDE SER ADMINISTRADA CON POCA AVERSION Y DOLOR.
