A substantially solvent-free matrix layer containing (−)-5,6,7,8-tetrahydro-6-[propyl-[2-(2-thienyl)ethyl]amino]-1-naphthalenol is produced by adding an active substance to an adhesive solution, coating the resultant active substance-containing adhesive solution onto a suitable sheet, and removing the solvents in a drying process to give said substantially solvent-free matrix layer. |
