The aim of this study was to optimize and assess the potential of nanostructured lipid carriers (NLC), prepared by the hot ultrasonication method, as carrier for methotrexate (MTX), highlighting the application of factorial design. Preliminary screening drug/lipid solubility, allowed us to select Witepsol(®) E85 as the solid lipid and Mygliol(®) 812 as(More)
Efavirenz (EFZ) is one of the most used drugs in the treatment of AIDS and is the first antiretroviral choice. However, since it has low solubility, it does not exhibit suitable bioavailability, which interferes with its therapeutic action and is classified as a class II drug according Biopharmaceutical Classification System (low solubility and high(More)
This work aimed to design dapsone (DAP) amorphous Polymeric Dispersions (PD) using design of experiments (DoE) and response surface methodology (RSM) as optimization tools in order to tailor the biopharmaceutical properties toward its oral delivery. A two-factor, three-level (3(2)) statistical design was implemented to study the influence of input variables(More)
The aim of the present work was to develop and optimize surface-functionalized solid lipid nanoparticles (SLNs) for improvement of the therapeutic index of dapsone (DAP), with the application of a design of experiments. The formulation was designed to target intestinal microfold (M-cells) as a strategy to increase internalization of the drug by the infected(More)
The poor water solubility tops the list of undesirable physicochemical properties in the drug discovery and Solid Dispersions (SDs) has been frequently used to enhance dissolution of such compounds. Although, some challenges limit the studies of SD commercial application. During recent years, the Quality by Design (QbD) approach has begun to change drug(More)
