Abstract: APLICAÇÃO DA PREPARAÇÃO DE MITOXANTRONA NA PREPARAÇÃO DE FÁRMACO PARA DIAGNÓSTICO E TRATAMENTO DE DOENÇAS RELACIONADAS À TIREOIDECTOMIA. Uma aplicação de uma preparação de mitoxantrona na preparação de um fármaco para diagnosticar e tratar uma doença relacionada à tireoidectomia e uso de mitoxantrona e/ou um sal farmaceuticamente aceitável da mesma na preparação de um marcador linfático para prevenir a coloração errada da glândula paratireoide, impedir cortes incorretos da glândula paratireoide ou reduzir a taxa de cortes errados da glândula paratireoide. A injeção local de um fluido de injeção de cloridrato de mitoxantrona não ocasionaria coloração errada da glândula paratireoide e pode reduzir a taxa de corte errado da glândula paratireoide, protegendo bem as glândulas paratireoides; além disso, nenhum efeito colateral tóxico local ou sistêmico é encontrado após a injeção local. A presente invenção tem boa tolerabilidade, eficácia e segurança e fornece uma nova ideia de tratamento na cura radical de doenças da tireoide para pacientes que sofrem de doenças relacionadas à tireoidectomia.
