Ciclodextrinas: formação de complexos e sua aplicação farmacêutica

Abstract

O número de moléculas com problemas de solubilidade, biodisponibilidade e permeabilidade tem vindo a aumentar. As ciclodextrinas são oligossacarídeos cíclicos com uma cavidade central hidrófoba, cuja estrutura permite formar complexos de inclusão estáveis com diversos fármacos. A complexação com ciclodextrinas permite optimizar os diversos sistemas transportadores constituídos por este tipo de fármacos, assim como solucionar problemas devidos a propriedades indesejáveis como instabilidade, más características organolépticas ou potencial irritação. The number of molecules with problems of solubility, bioavailability and permeability is increasing. Cyclodextrins are cyclic oligosaccharides with a hydrophobic central cavity, whose structure can form stable inclusion complexes with various drugs. Complexation allows the optimization of drug delivery of such drugs, and to solve problems due to undesirable properties such as instability, poor organoleptic characteristics or irritation.
