Transfer technology features and sett lement in industrial automotive of liposomal cytostatic production

Abstract

An integral part of the original medicines development in pharmaceutical industry is a thorough, coordinated procedure for pharmaceutical technologies reproduction at various stages of development and production – technology transfer.
Aim. To study and to analyze the frequent transitions in the pharmaceutical industry, to investigate the problems of technology scaling observed during the transfer, in the manufacture of nanosized dosage forms, and to propose ways to solve them.
Materials and methods. For liposomes preparation it was purchased egg phosphatidylcholine from Lipoid, Germany. Lyophilization was carried out in the Quarco model, P.R.C. The encapsulation degree was determined by HPLC on a Shimadzu LC-20 instrument manufactured in Japan, according to a method developed earlier.
Results. Liposomal drugs related to complex structured drugs, and the transfer process during their development is one of the stages of development and requires an additional adaptation experiment. We were tasked with make an experience gained in the transfer and scaling of the production of liposomal cytostatics. Additional experiments were carried out, allowing the results of primary pharmaceutical development to be transferred to industrial equipment without loss of quality. Features of the scale of such technological processes as a lipid film obtaining, high pressure extrusion, ultrafiltration, sterilizing filtration and freeze drying was analyzed.
Conclusions. As a result of the conducted researches the basic variants of technology transfer during a life cycle of the finished medical form were analyzed. The peculiarities of the transfer and scaling of nanosized liposomal formulation technology, in particular the production of a lipid film, estrusion at high pressure, ultrafiltration, sterilizing filtration and lyophilic drying are considered.
