Abstract

Se proporcionan composiciones de gel de depósito inyectables y kits que proveen un excipiente para modular un índice de liberación y estabilizar agentes beneficiosos. También se proveen métodos para administrar y preparar ese tipo de sistemas. Las composiciones de gel comprenden polímeros biodegradables y biocorroible y solventes inmiscibles en agua en cantidades eficaces para plastificar los polímeros y formar geles con los polímeros. Los excipientes adecuados incluyen modificaciones del pH, agentes reductores y antioxidantes. Reivindicación 1: Una composición de gel de depósito inyectable para la administración sostenida de un agente beneficioso que comprende: un vehículo de gel que comprende un polímero biodegradable y biocompatible y un solvente inmiscible en agua en una cantidad eficaz para plastificar al polímero y formar un gel con el mismo; un agente beneficioso disuelto o dispersado en el vehículo en gel; y un excipiente para modular un índice de liberación, en el cual el excipiente estabiliza al agente beneficioso compensando los efectos de la degradación del polímero; en donde la administración sostenida se produce durante un período de entre aproximadamente 24 horas y aproximadamente doce meses después de la administración.
