Abstract

implante subcutâneo reabsorvível de longa duração com liberação prolongada de substância farmacologicamente ativa pré-concentrada em polímero para tratamento da insuficiência adrenal crônica ou hipocortisolismo. o presente pedido de privilégio de invenção é voltado ao setor médico e compreende um implante subcutâneo reabsorvível de longa duração com liberação prolongada de substância farmacologicamente ativa pré-concentrada em polímero para tratamento da insuficiência adrenal crônica. o implante é inserido por via subcutânea e possui liberação contínua do ativo por um período de tempo prolongado. essa liberação visa garantir um nível sérico do fármaco eficiente, constante e prolongado para o tratamento da insuficiência adrenal crônica. o implante desse invento pode ter em sua constituição apenas a hidrocortisona, mas é preferencialmente formado por partículas de hidrocortisona dispersas homogeneamente em uma matriz polimérica bioerodível e bioabsorvível. essa matriz polimérica pode ser formada por um polímero ou uma mistura de polímeros. ainda, outra opção de implante para tratamento da insuficiência adrenal crônica são os implantes não biodegradáveis. a liberação da droga nesse sistema ocorre através da difusão, a uma taxa relativamente constante, e é possível alterar a velocidade de liberação da droga através da espessura ou material dessa membrana. nesse sistema há a necessidade de retirada do implante ao final do tratamento.
