Nano-delivery systems based on carvacrol prodrugs and fibrous clays

The fibrous silicates, Palygorskite and Sepiolite, were investigated as low-cost nanocarriers for three carvacrol prodrugs to ameliorate their pharmacokinetic and biopharmaceutic profiles. Adsorption equilibrium studies were performed in order to obtain a drug-clay hybrid system. These hybrid systems were characterized by thermal analysis, X-ray diffraction, and Fourier transform infrared spectroscopy, to study the degree and kind of...
