Lipophilic drugs medium-chain triglycerides

There are a few marketed drug delivery systems containing microemulsions that are related to the lipid systems we describe here. Sandimmune Neoral (Novartis, Switzerland) [17], which delivers the lipophilic peptide cyclosporin A, is based on medium-chain triglycerides obtained from coconut oil, a semisynthetic emulsifier (ricinoleate), and propylene glycol. The absorption of the drug taken orally as a microemulsion increases dramatically compared to that of an aqueous suspension [17]. Another marketed example, in which Cs/Cio triglycerides from coconut oil are used, is a soft gelatin capsule of vitamin D3 [18].
