Liposomes incorporating sodium deoxycholate for hexamethylmelamine (HMM) oral delivery: development, characterization, and in vivo evaluation

Liposomes incorporating sodium deoxycholate (NaDC) were prepared by the method of reverse phase evaporation and used for drug delivery by the oral route. Hexamethylmelamine (HMM), an anti-tumor agent, was chosen as a model drug and encapsulated into liposomes incorporating NaDC (NaDC-Lip). Several properties of NaDC-Lip containing HMM (HMM NaDC-Lip), such as particle size, entrapment efficiency, pinacyanol chloride (PIN) spectral characteristics with various molar ratio of NaDC/PC, as well as the vesicle stability measurements with calcein were evaluated. In vivo, the area under the plasma concentration-time curve obtained from the pharmacokinetics study of HMM NaDC-Lip was found to be approximately 9.76- and 1.21-fold higher than that of HMM solution and HMM Lip, respectively, indicating that NaDC-Lip can be used as a potential carrier for oral drug administration.
