Liposomal formulations of hydrophobic lactone drugs in the presence of metal ions

摘要

Provided is a liposome comprising a hydrophobic lactone drug and a cyclodextrin, wherein the liposome has an intraliposomal pH and cyclodextrin concentration such that upon administration of the liposome to a subject, the liposome exhibits a uniform release profile of the hydrophobic lactone drug. Also provided is a method of administering a hydrophobic lactone drug to a subject in need thereof. The method comprises administering a liposome to the subject in need, wherein the liposome comprises the hydrophobic lactone drug and a cyclodextrin. The liposome has an intraliposomal pH and cyclodextrin concentration such that upon administration of the liposome to the subject, the liposome exhibits a uniform release profile of the hydrophobic lactone drug.
