Sumario:Triazole antifungal agents as Fluconazole or Itraconazole are usal drugs for treatment and prophylaxis of fungal diseases. Liposomes are ideal vehicles for hydrophilic and lipophilic drug transport and new strategies are being studied about them in order to improve drug transport and release. The objective of the study was evaluating and comparing the importance of the grade of albumin binding of Itraconazole and Fluconazole in the formulation, as well as assessing the incorporation of a cationic lipid: dimethyldioctadecylammonium and determinating its influence in the binding grade of the antifungal drugs. Liposomes were prepared using the sonication method, in absence of organic solvents, and they were albumin coated to form the microparticles. The drug concentration of them was determinated by an high-performance liquid chromatography technique. The drug fraction in the microparticles was higher for Itraconazole ones. Albumin solubilized part of the Itraconazole, but in that case the presence of dimethyldioctadecylammonium is needed to microparticles forming.
