Аннотация

Nanostructured spherical calcium carbonate particles with average sizes of 3.8 µm and 550 nm have been fabricated. Optimal conditions for adsorption of central anesthetic loperamide on these particles are found. The influence of particle size on the adsorption efficiency is studied. The efficiency of micron and submicron vaterite particles as carriers for intranasal loperamide delivery is compared using in vivo tests on laboratory animals.
