SUBCUTANEOUS APOMORPHINE INFUSION IN PARKINSONS-DISEASE - DOES IT HAVE A ROLE

Apomorphine is a potent dopamine agonist at both D1 and D2 receptors a nd has been used successfully for treating the 'on/off' phenomenon in Parkinson's disease. We report our experience with apomorphine in trea ting the 'on/off' phenomenon in L-dopa responsive idiopathic Parkinson 's disease. Thirteen such patients were commenced on apomorphine infus ions. Their mean age was 69 (range 53-80) years and the mean duration of the disease was 15 (range 6-28) years. The clinical response to apo morphine was good in four patients, fair in two, unchanged in five and worse in two. Activities of daily living improved in six, were unchan ged in five and worse in two. When the response was poor or showed no change, apomorphine was discontinued. In addition, apomorphine was als o discontinued in three patients who had had a fair/good response but suffered side effects of hallucinations, delusions and psychosis, lack of cooperation or found the pump inconvenient. Apomorphine was contin ued in only three patients out of 13.
