Talidomida: a fénix renascida das cinzas

Abstract

A talidomida marcou o seu nome na história pelas piores razões devido às malformações congénitas que causou em crianças nas décadas de 50 e 60 do século passado. Recentemente descobriram-se novas aplicações clínicas que prometem relançar a maneira como esta molécula é vista pela comunidade científica e a sociedade em geral. Por essa razão, neste trabalho foi feita uma revisão farmacocinética, explorando os principais parâmetros, e uma revisão farmacodinâmica, demonstrando o nosso conhecimento até à data sobre o seu mecanismo de ação. Foi igualmente realizado um levantamento dos principais efeitos secundários e possíveis interações da talidomida, bem como uma compilação dos dados relativos à eficácia da talidomida em doenças dermatológicas, gastrointestinais, tumores não-sólidos e sólidos, bem como em várias outras patologias. O potencial desta molécula é enorme embora só esteja autorizada até ao momento para o tratamento do Eritema Nodoso da Lepra e do Mieloma Múltiplo, neste último em associação com a dexametasona. A sua utilização cada vez maior e o risco de teratogenia ainda real levaram ao desenvolvimento do programa STEPS pela empresa Celgene, que promove o controlo da prescrição, da dispensa e o uso racional da talidomida. The molecule thalidomide carved its name in history for the worst reasons, mostly due to the malformations brought upon children in the 5th and 6th decades of the last century. Recently, new found uses for this drug have promised to remodel its insight from the scientific community as well the general public. So it was necessary to revise all data, pharmacokinetic, with the various parameters, and pharmacodynamics, exploring its mechanism of action, at least as far as it has been revealed. A compilation of data from side effects and possible interactions was performed and the next step involved the gathering of information about its possible effectiveness and significance in various diseases, such as dermatologic, gastrointestinal, oncological non-solid and solid tumors, as well as other varied pathologies. Within it, lays the clinical utility of thalidomide in the only two diseases for which treatment it has been approved for, Erythema Nodosum Leprosum, and Multiple Myeloma, the latter in combination with dexamethasone. Its recent found uses and more growing have led to the development of the STEPS program by the Celgene company, which promotes the control of the prescription, dispense, and rational use of thalidomide.
