LIPOSOMAL COMPOSITIONS OF GLUCOCORTICOID AND GLUCOCORTICOID DERIVATIVES

摘要

Provided are pharmaceutical compositions including a glucocorticoid or glucocorticoid derivative stably encapsulated in a liposome. The glucocorticoid or glucocorticoid derivative is selected from an amphipathic weak base glucocorticoid or glucocorticoid derivative having a pKa equal or below 11 and a logD at pH 7 in the range between −2.5 and 1.5; or an amphipathic weak acid GC or GC derivative having a pKa above 3.5 and a logD at pH 7 in the range between −2.5 and 1.5. The therapeutic effect of the pharmaceutical composition of the invention was exhibited in vivo with appropriate models of multiple sclerosis and cancer.
