[Sublingual administration of apomorphine in the treatment of motor fluctuations in Parkinson disease].

Apomorphine, a mixed dopaminergic agonist was given sublingually to 12 patients with Parkinson's disease disabled by severe on-off fluctuations. The patient's mean age was 57 years and the duration of Parkinson's disease was 12 years. All patients were also given domperidone (60 mg/day). Apomorphine was administered as soon as the off periods appeared. On periods were observed in 11 patients, with a mean apomorphine dose of 40 mg for each administration (extremes values: 20-60 mg). One patient had no motor benefit after an apomorphine dose of 120 mg. The mean duration of daily off periods was reduced by 64 per cent in 11 patients, for a mean duration of 8 months (extremes values: 2-12 months). Four patients developed stomatitis or gingival edema and stopped treatment. This pilot study shows that sublingual apomorphine, during a mean period of 8 months, significantly decreases off periods in parkinsonian patients. Others studies are necessary to confirm these results.
