Henkel’s proprietary PROLOC bioadhesive technology provides a superior means to deliver therapeutic agents locally and across mucosal membranes at various absorption sites. PROLOC bioadhesives provide increased bioadhesive properties and the capacity for higher drug loading, while remaining gentle to the mucosa. The PROLOC system can be compressed into a tablet, utilized as a powder or cast as a film. Several clinical trials have been performed to demonstrate the successful delivery of drugs across the mucosa or for local therapies using the PROLOC technology.
