Abstract

Today, the development of drug delivery systems is focused on creating of products with improved pharmacological efficacy and safety of action for the patient. Therefore, the development of systems such as liposomes, emulsions and polymer nanoparticles is a promising direction of development of modern pharmacy.

The objective of the work: To study the optimal extrusion parameters during liposomal irinotecan creation. For the experiment: egg phosphatidylcholine (Lipoid, Germany); cholesterol (Sigma-Aldrich, USA) were using. Liposomes were obtained by «chemical gradient» method.

During the experiment, two homogenization techniques were tested. Sonication and extrusion at high pressure methods were applied to cholesterol modified lipid membranes. It is proved that the sonication method is not applicable because of the particles with diameters greater than 1 000 nm formation.

Two different extruders were used. It was determined, that Microfluidics Microfluidiser M-110P more appropriate for preparation of current liposomal emulsion. Chosen extruder can be applicable for preparation on the homogenous liposomal emulsion without the presence of particles larger than 1 000 nm.

It was tested extrusion mode for liposomes with the following composition of the lipid bilayer: egg phosphatidylcholine/cholesterol 80/20 by weight. For achieving liposomes with diameter 107 nm it is necessary 7 extrusion cycles at 1 500 bar at 20 °C.
