Liposomes are being used as unique drug delivery systems due to their ability to encapsulate both hydrophilic and hydrophobic drugs, as well as for the fact that they improve the disadvantages of free drug administration. However, liposomes have a significant disadvantage - low encapsulation efficiency. In the research carried out, 1,2-distearoyl-sn-glycero-3- phosphocholine (DSPC) and cholesterol (Chol), in the ratio (n/n) of 2:1, 3:1 and 4:1 respectively, were used to prepare the liposomes. Blank liposomes (LIP) and vancomycin hydrochloride (VANKA) containing liposomes (VANKA-LIP) were prepared for each of the DSPC and Chol compositions. The aim of our study was to evaluate the effect of liposome composition on the VANKA encapsulation efficiency and release kinetics.
