ABSTRACT

Though organ transplantation has evolved in many a ways over the years, it is not without the disadvantage of causing rejections. Cyclosporin, azathioprine and corticosteroids are time tested and efficacious; however each is accompanied with its own array of disadvantages. Sirolimus is a relatively new immunosuppressant isolated from a macrolide antibiotic. It may have a beneficial role in prophylaxis of rejection as well as treatment of refractory rejection. It also has antifungal, antitumor and anti-smooth muscle proliferative roles.

ABSTRACT

Os autores fazem, inicialmente, uma revisão dos possíveis mecanismos fisiopatológicos envolvidos na reestenose coronariana, dando ênfase especial aos aspectos relacionados à reestenose intra-stent. Abordam, de forma sucinta, as várias estratégias utilizadas para diminuir a incidência de reestenose. Por fim, fazem uma revisão ampla a respeito do uso de stents farmacológicos para a prevenção primária de reestenose, suas limitações e perspectivas futuras, discorrendo sobre os tipos de plataformas, os polímeros e os agentes farmacológicos utilizados, além de trazerem os resultados dos principais estudos clínicos relacionados ao uso dos agentes sirolimus e paclitaxel
