Biocompatible Natural Polymers and Cutting-Edge Fabrication Techniques in the Development of Next-Generation Oral Thin Films for Enhanced Drug Delivery Systems.

Oral thin films are changing the way drugs are delivered, making drug administration more convenient and patient-friendly. This review delves into the fascinating possibilities of natural polymers in thin film design. We consider the benefits of biocompatible polymers produced from chitosan, gelatin, and pullulan. Their intrinsic biodegradability and safety make them excellent for use with a wide range of patients. Additionally, the research investigates novel strategies for creating these distinctive drug delivery systems. We look beyond standard solvent casting techniques, hot melt extrusion methods, rolling methods, etc. These technologies provide exact control over film qualities, allowing for tailored medication delivery and increased patient compliance. This review seeks to bridge the gap between natural polymers and cutting-edge fabrication processes. By investigating this combination, we pave the road for the development of next-generation oral thin films that are more efficacious, patient-acceptable, and environmentally-friendly.
