Resumo
A rivaroxabana pertence ao grupo dos agentes antitrombóticos e é utilizada para o tratamento e a prevenção do tromboembolismo venoso que engloba a trombose venosa profunda e a embolia pulmonar. É administrada por via oral sob a forma de comprimidos revestidos nas doses de 2,5mg, 10mg, 15mg e 20mg. O seu desenvolvimento surgiu devido à necessidade de novos anticoagulantes administrados por via oral. Nesse sentido, o objetivo desse trabalho foi desenvolver uma formulação de comprimidos de liberação imediata contendo rivaroxabana na dose de 20 mg, apresentando um perfil de dissolução semelhante ao do medicamento referência Xarelto® 20mg. Para isso foi preparada uma formulação contendo uma mistura física entre a rivaroxabana e o polímero hidrofílico polietilenoglicol 4000, de forma a melhorar sua solubilidade e dissolução. A partir da formulação otimizada, foram preparados comprimidos os quais apresentaram similaridade entre os perfis de dissolução dessa formulação e do medicamento referência.
Rivaroxaban belongs to the group of agents antithrombotics and is used for treating and preventing Venous Thromboembolism, which comprehends Deep venous thrombosis and pulmonary embolism. It is administered orally as coated pills in the doses of de 2,5, 10, 15 and 20mg. Its development came up as a need for new orally administered anticoagulants. In this way, this paper aims to develop a new formulation of pills of immediate release, containing rivaroxaban in the dose of 20mg, presenting a profile of dissolution similar to the medicine of reference, Xarelto 20mg. To do this, it was prepared a solution containing a physical mixture of rivaroxaban and hydrophilic polymer polyethylene glycols 4000, in order to enhance its solubility and dissolution. From this optimized solution, the pills prepared showed similarity between its solution profiles and the medicine used as reference.
