Uso de ciclodextrinas nas formulações para administração pulmonar

Abstract

A via pulmonar é considerada uma via alternativa para a administração não invasiva de fármacos, a nível local e sistémico. Nos últimos anos, a administração pulmonar de fármacos tornou-se numa terapêutica promissora e valiosa, para o tratamento de doenças não respiratórias, com o objetivo de alcançar a rápida e eficaz absorção sistémica. Os pulmões têm uma vasta área de superfície de absorção, uma mucosa membranar extremamente fina e um fluxo sanguíneo elevado, fornecendo boas condições para a absorção de fármacos. Na via pulmonar o efeito do metabolismo de 1ª passagem é evitado e também os efeitos adversos sistémicos. Contudo, a baixa solubilidade aquosa de alguns fármacos, pode ser uma condição limitativa para a sua administração pulmonar. As ciclodextrinas (CDs) podem ser utilizadas como transportadores de fármacos para aumentar a sua absorção. As CDs formam complexos de inclusão com os fármacos, alteram as suas propriedades físico-químicas e biológicas, e aumentam a solubilidade dos fármacos pouco solúveis, conferindo maior biodisponibilidade e estabilidade farmacológica.

Pulmonary route its considered an alternative route to the non-invasive administration of drug substances for local and systemic delivery. In the past few years the pulmonary administration of drugs has became a promissing and valuable therapy for the treatment of non-respiratory diseases, in order to achieve rapid and efficient systemic absorption. The lungs have a large absorptive surface area, extremely thin absorptive mucosal membrane and a high blood flow, which supply good conditions for drug absorption. In pulmonary route the first pass metabolism of drugs are avoided, and also some systemic side effects. However, the poor aqueous solubility of some drugs, could be a limited condition for the pulmonary drug administration. Cyclodextrins (CDs) can be used as drug carriers to improve drug delivery and absorption. CDs form inclusion complexes with drug substances, change their physicochemical and biological properties, and increase the solubility of poor soluble drugs, providing higher bioavailability and drug stability.
