About 40% of the new chemical entities show poor bioavailability due to their low water solubility. To increase the solubility of drugs, self-microemulsifying drug delivery systems (SMEDDS) are considered as an ideal technology to enhance the permeability of poorly soluble drugs in GI membranes. Self (micro)emulsifying drug delivery systems include liquid self (micro)emulsifying drug delivery systems and solid self (micro)emulsifying drug delivery systems in general. Solid self (micro)emulsifying drug delivery systems are solid formulations prepared by mixing self (micro)emulsifying components with suitable solid materials. The self (micro)emulsifying drug delivery system encapsulates the insoluble drug to form O/W type emulsion droplets with small particle size, thereby increasing the solubility of the drug; at the same time, the surfactant is also beneficial to increase the dissolution and permeability of the drug.

CD Formulation's self-emulsifying drug delivery system service can evaluate the bioavailability of drugs and suggest suitable product solutions. Our professional team has the ability to establish and validate analytical methods, determine oil/water partition coefficients, investigate the equilibrium solubility of drugs in water, oil, surfactants, and provide co-surfactant selection.
After the preparation of the self-emulsifying drug delivery system, the particle size after emulsification was measured and the morphology was investigated, and the stability of the emulsion after self-micro-emulsion was evaluated through in vitro dissolution experiments.
If your drug is insoluble or insoluble, please contact us, and our professional team will choose a suitable way to customize services for you to help you better develop your drug.
Microemulsion preparation can improve the solubility of water-insoluble drugs and fat-soluble drugs, promote the absorption of macromolecular drugs in vivo, and improve their bioavailability.
Enhance the stability of unstable drugs.
Small and uniform particle size, so that the inclusion of drugs to improve the dispersion, promote drug absorption through the skin.
