Why consider a lipid-based drug delivery system (LBDDS)?
Approximately 90 percent of molecules in the discovery pipeline, and approximately 40 percent of drugs with market approval, are poorly water soluble. Advanced delivery technologies, like lipid-based systems, are an alternative solution to safely and effectively deliver the proper therapeutic dose to patients.
Unlike conventional tablets or powder-filled capsules, LBDDS can present the drug compound in a solubilized state, eliminating dissolution rate limited absorption and improving bioavailability. For highly potent drugs, dosage form content uniformity may also be improved. Lastly, LBDDS may circumvent hepatic first-pass metabolism by promoting lymphatic transport.
“However, the range of lipidic excipients and the abundance of factors that go into determining which combinations of lipids, cosolvents, and surfactants to select makes LBDDS a complex, formulation-dependent technology.
