Abstract:

Hot Melt Extrusion (HME) is a continuous process manufacturing technology that can be successfully used for the development of water insoluble active substances. By providing excellent mixing of a drug and a polymer carrier within the extrusion barrels HME can facilitate increased dissolution rates of insoluble drugs. HME induces drug - polymer interactions (e.g. via H-bonding) where the drug is either amorphous or molecularly dispersed within the polymer carrier and thus increasing the solubility of drug. HME is a versatile technology that can be used for both hydrophilic and hydrophobic drugs and manufacture high drug loaded extrudates in the form of pellets, granules or thin films. Various approaches can be used to select the appropriate drug - polymer combinations such as Hansen solubility parameters and more recently molecular modeling approaches. Several examples of miscible drug - polymer blends are presented in these studies where extruded materials are evaluated as finished products. HME is a novel continuous manufacturing process, which also combines quality by design (QbD) approaches and process analytical tools (PAT) for the development of oral solid dosage forms. It is anticipated that HME will play a key role in the future development of poorly soluble drugs.
