Abstract

V originále

Incorporation of lipophilic drugs into liquid self-emulsifying systems proves to be an effective strategy for augmenting their solubility and bioavailability. Presently, there is a significant focus on exploring the potential of solidifying these systems, e.g., the formulation of pellets through extrusion/spheronization. Solid systems offer numerous advantages, including ease of dosing, manipulability, and enhanced stability. Nonetheless, the broader utilization of self-emulsifying systems would greatly benefit from the modified release, e.g., enabling drug delivery to distal regions of the intestine for oral application. Regrettably, the scientific community has provided limited information on this topic. Although some information exists regarding challenges in coated self-emulsifying pellets, comprehensive investigations remain scarce. This experimental study aims to formulate self-emulsifying pellets coated with Eudragit® L for precise drug delivery to the small intestinal region and to provide a detailed analysis and explanation of the observed difficulties. In this experimental study, dissolution profiles after three months suggest that introducing a sub-layer and TEC reduction could be a solution for the modified release of self-emulsifying pellets. Lastly, it would be advantageous to identify whether self-emulsifying formulation, thymol, or a different variable is a source of presented incompatibility.
