    摘要: 4-(Polyalkoxyphenyl)-2-pyrrolidones of the formula ##STR1## wherein R.sub.1 and R.sub.2 each are hydrocarbon of up to 18 carbon atoms at least one being other than methyl, a heterocyclic ring, or alkyl of 1-5 carbon atoms substituted by halogen, OH, COOH, alkoxy, alkoxycarbonyl or an amino group; R' is H, alkyl, aryl or acyl; and X is O or S; possess neuropsychotropic activity. The compounds wherein X is O can be produced by saponifying and decarboxylating a corresponding 2-pyrrolidone-3-carboxylic acid alkyl ester or cyclizing a corresponding 3-phenyl-4-amino-butyric acid or alkyl ester thereof. The pyrrolidones can be converted to the corresponding thiopyrrolidones by reaction with phosphorous pentasulfide in the presence of base.

    摘要: 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).
