Abstract
The nanoemulsified composite (NEC) delivery system is a patented technology based on the incorporation of a double microemulsion into microporous carrier. This approach was applied on the very water insoluble ubidecarenone drug. The resulting composite powder showed good technological properties such as flowability; also good stability was evidentiated, with size of the nano-droplets released from the systems maintained equal to the starting size also after a long storage. Furthermore very good biopharmaceutical properties were originated, with water solubility concentrations up to 50-fold higher than pure ubidecarenone and oral absorption in rats up to three-fold greater than standard commercial products in terms of plasma levels and AUC.
