EFEITO DE SURFACTANTES NA ESTABILIDADE DE COMPOSTOS DE USO TERAPEUTICO

A critical revision of literature as regards to the drug stability in the presence of surfactants were realized. The functional groups envolved in the drug decomposition were used to the development of the discussion. The analysis indicated that the detergent effect can be used to control the rates and mechanisms of drug decomposition and to obtain specific information about the drug reactivity in the environment of pharmacological action.

Effect of micelles, microemulsions and other supramolecular aggregates on the hydrolysis of β-lactam antibiotics

A critical revision of the literature was made regarding the stability of β-lactam antibiotics in the presence of surfactants. The factors involved in the drug decomposition were analyzed in the development of the discussion. The analysis has indicated that some organized systems obtained from surfactants can be used to control rates and mechanisms of antibiotic decomposition. These organized systems can also be used to obtain specific information about the drug reactivity in a microenvironment similar to the site of pharmacological effect.
