Abstract
The aim of the work was the successful encapsulation of etoposide (ETO) and vinorelbine (VIN). Liposomes made from dipalmitylphosphatidylcholine (DPPC), liposomes containing both drugs (DPPC/ETO/VIN) and control liposomes DPPC/ETO and DPPC/VIN were prepared by the mREV method at 328 K. Liposome entrapped drugs were separated from free drugs by ultracentrifugation. The degree of encapsulation of drugs into liposome vesicles DPPC/ETO, DPPC/VIN and DPPC/ETO/VIN was estimated using UV spectrofluorescence after ultracentrifugation. The phase transition temperature was determined for all types of liposomes. The encapsulation efficiency, which is a measure of the percentage of the total compound entrapped within the liposome, is also determined.
