Transdermal therapeutic system with two-phase release profile

Abstract

The present invention relates to a transdermal therapeutic system (TTS) consisting of an impermeable coating, a matrix containing an ergoline compound having the formula (I) or a physiologically compatible salt or derivative thereof, wherein R1 denotes an H atom or a halogen atom and R2 is an alkyl group having 1 to 4 carbon atoms and denotes a single or double bond, and a removable protective layer, wherein the ergoline compound or a physiologically compatible salt or derivative thereof is stabilised by an antioxidant and a basic polymer. The TTS is characterised in that the matrix contains at least one hydrocarbon having 8 to 18 carbon atoms in a straight or branched chain, which has a functional group at the end of the alkyl chain and/or Aloe Vera, so that in a first phase (0-5 hours after application) only 0-20% of the therapeutically desired steady-state plasma concentration of the ergoline compound is achieved and the therapeutically desired steady-state plasma concentration of the ergoline compound is only achieved in a second phase (5-20 hours after application).
