Definitions

  • the present invention relates to a transdermal therapeutic system for ergoline compounds having a new two-phase release profile in which in a first phase (0-5 hours after administration) only 0-20% of the therapeutically desired steady state plasma concentration of the ergoline compound is achieved and then only in a second phase (5-20 hours after administration), the therapeutically desired steady state plasma concentration of the ergoline compound is achieved.
  • dopaminergic therapies of Parkinson's disease and other conditions such as Restless Legs Syndrome and other neurological disorders associated with brain damage or injury, if fully effective, will be affected by a large number of side effects.
  • the adjustment of oral dopaminergic therapies is either using levodopa alone or with the aid of enhancers (MAO inhibitors, COMT inhibitors) or dopamine agonists. It is based on the individual bioavailability and the therapeutic needs of a patient, ie, the therapy is titrated, so to speak. This titration may involve up to five different agents with unpredictable metabolism or other interactions.
  • transdermal preparation of a dopamine agonist (Table 1; -3-), which is normally prepared to deliver the active ingredient persistently, is apparently not generally capable of significantly reducing peripheral accessory defects as compared to conventional immediate-release formulations.
  • transdermal formulations can compensate for skin-binding effects of the active agent during the first phase of release, by overcharging the system, and / or introducing defined amounts of the drug into the outer adhesive layer. This is likely to indicate a more consistent delivery of the drug to the systemic circulation but, in the case of drugs with a narrow therapeutic range, is an inappropriate method of administration to prevent side effects.
