Immune-suppressive agents such as methylprednisolone and cyclosporine exert tremendous side effects, because of high dosage and long-term application required for immune suppression after organ transplantation. Major side effects of methylprednisolone include bleeding of the gastro-intestinal tract, hypertension, and osteoporosis, whereas cyclosporine is nephrotoxic. Liposomes are phospholipid particles that allow delivery of drugs preferentially to the reticuloendothelial system. They can be prepared from phospholipids, such as lecithin from soybean or egg yolk, other specific or modified lipids or from membrane-spanning tetraether lipid (TEL), which can be extracted and purified from archaeal cell membranes. One advantage in the use of liposomal application is reduced toxicity of many drugs. We report on various liposomal preparations of cyclosporine, methylprednisolone (L-MPL) and its palmitate derivative (L-MPLP). It has been documented that liposomal cyclosporine A (L-CsA), 1.75 mg/kg/ day for seven days has potential for use as an immune-suppressive agent in rats with increased efficacy and decreased nephrotoxicity compared to commercially available forms of intravenous CsA. Liposomal methylprednisolone (L-MPL) 2 mg/kg, intravenously (IV), twice a week shows significantly prolonged cardiac allograft survival in rats and tissue-selective sequestration of the drug in comparison with the same dosage regimen of methylprednisolone in solution, administered daily. We report on organ distribution of L-MPLP in rats after intraperitoneal (IP) administration. Conclusion: Liposomal preparations of immunosuppressants have significantly higher immune-suppressive potential and lower toxicity than non-liposomal preparations. Bipolar TEL can be extracted, fractionated and purified from archaea to form stable liposomes which are extremely resistant, even to gastric fluid. Hence, TEL liposomes allow (besides IV and IP) for oral administration of immunosuppressants after organ transplantation with pharmacological and toxicological advantages over common liposomal phospholipid bilayer preparations. © 2021 Oriental Scientific Publishing Company.
