Abstract
IMPLANTE SUBCUTÂNEO REABSORVÍVEL DE LONGA DURAÇÃO COM LIBERAÇÃO PROLONGADA DE SUBSTÂNCIA FARMACOLOGICAMENTE ATIVA PRÉ CONCENTRADA EM POLÍMERO PARA TRATAMENTO DO HIPOTIREOIDISMO E PROCESSO. O presente pedido de privilégio de invenção é voltado ao setor de saúde e compreende um implante subcutâneo reabsorvível de longa duração com liberação prolongada de substância farmacologicamente ativa pré-concentrada em polímero para tratamento do hipotireoidismo. O presente pedido é um implante biodegradável de triiodotironina (T3) isolada, tiroxina (T4) isolada ou associação de triiodotironina (T3) e tiroxina (T4) para tratamento do hipotireoidismo em matriz polimérica. 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 do hipotireoidismo. O implante adota o padrão cilíndrico (1), em formato de haste, provido de pontas retas ou arredondadas, com comprimento entre 2 a 25 mm e o diâmetro de 1 a 6 mm. A mistura de ativos para fabricação do implante pode ser moldada a partir da pressão ou do calor, de forma a não comprometer a eficácia da droga nem degradar o material polimérico. As opções de técnicas para moldagem do implante podem ser: moldagem por injeção, moldagem a quente, moldagem por compressão ou moldagem por extrusão.LONG-TERM REABSORBABBLE SUBCUTANEOUS IMPLANT WITH PROLONGED RELEASE OF PRE-CONCENTRATELY PHARMACOLOGICALLY ACTIVE SUBSTANCE IN POLYMER FOR HYPOTHYROIDISM TREATMENT AND PROCESS. The present invention privilege application is aimed at the health sector and comprises a long-term resorbable subcutaneous implant with prolonged release of a pre-concentrated polymer pharmacologically active substance for the treatment of hypothyroidism. The present application is a biodegradable implant of triiodothyronine (T3) alone, thyroxine (T4) alone or combination of triiodothyronine (T3) and thyroxine (T4) for treating hypothyroidism in polymeric matrix. The implant is inserted subcutaneously and has a continuous release of the active for an extended period of time. This release aims to ensure an efficient, constant and prolonged serum level of the drug for the treatment of hypothyroidism. The implant adopts the cylindrical pattern (1), in the form of a rod, provided with straight or rounded tips, with a length between 2 and 25 mm and a diameter of 1 to 6 mm. The mixture of actives for manufacturing the implant can be molded from pressure or heat, so as not to compromise the drug's effectiveness or degrade the polymeric material. The options for implant molding techniques can be: injection molding, hot molding, compression molding or extrusion molding.
