I have seen Mary Baker today and she certainly isn't too keen for 1500 people phoning her asking her about Casaser\Cabergoline! To quote some literature I picked up at the X11th International symposium on PD on the drug it says "it is indicated for the treatment of symptoms of PD as adjuvant to levodopa plus dopa-decarboxylase inhibitor, in patients affected by on\off mobility problems with daily fluctuations in motor performance. Controlled clinical studies have demonstrated that the drug administered once daily at an average dose of 4mg\day following titration up to 5-6mg a day in the different studies) is effective in decreasing daily fluctuations in motor performance in PWP receiving levodopa\carbidopa therapy. Improvement of motor deficit has been demonstrated while substantially decreasing levodopa\cabidopa dose." I can't help you re: availability outside UK and I have no first hand knowledge of the drug at all. regards Emma
