Abstract:
Hot-melt extrusion (HME) is the process of pumping raw materials with a rotating screw under the elevated temperature and pressure through a die to from a product with the uniform shape. This technique combines many advantages of solid dispersion technology and mechanical preparation, including dust reduction, short duration of extrusion process, without use of organic solvents and water, without heat drying and hydrolysis, etc. In addition, it has the superiority in solubility, taste masking, drug stability and drug release. Besides, this technique has good reproducibility, high production efficiency, and it can be online monitored in the mass production. Therefore, this technique is widely used in the research and development of drug dosage forms involved in rapid and immediate drug release, sustained drug release, gastrointestinal drug site-specific release, transdermal drug delivery systems and so on. This paper reviews the advantages of HME and its recent application in the pharmaceutical research.
