Multi-layer dressing as medical drug delivery system

The method of manufacturing a dressing, comprising the steps of:

• a. mixing the components of the surface-contacting layer together to form a standardized aerated mixture;
• b. spreading the aerated mixture onto a smooth support to form a sheet of predetermined thickness;
• c. mixing the components of said drug containing layer to form a standardized aerated mixture;
• and
• d. spreading the aerated mixture of step c) on top of the mixure of step b) before the mixture of step b) is fully cured, and allowing both layers to cure simultaneously.

A method for manufacturing a dressing, comprising:

• the steps of:
• a. mixing the components of said surface-contacting layer together to form a standardized aerated mixture;
• b. spreading the aerated mixture of step a) onto a smooth support to form a sheet of pre-determined thickness, and allowing the sheet to fully cure;
• c. mixing the components of said drug reservoir layer to form a standardized aerated mixture;
• d. spreading the aerated mixture of step c) onto a smooth support to form a sheet of pre-determined thickness, and allowing the sheet to fully cure;
• and
• e. sealing the sheet obtained in step b) to the sheet obtained in step d).
