Cochleate Formulation Enhances the Stability of Lansoprazole in Acidic Condition

Abstract

Lansoprazole (LSP)-loaded cochleates were developed using dimyristoyl phosphatidylcholine (DMPC) and cholesterol in the presence or absence of dicetyl phosphate (DCP). Cochleates containing DCP exhibited unique cylindrical morphologies, resulting in improved LSP loading and enhanced stability in an acidic environment. Thus, we suggest that the use of negatively charged components, such as DCP, is needed to formulate cochleates using a neutrally charged lipid such as DMPC.
