1 OBJECTIVES: This study assessed the behavioural and pharmacokinetic effects of chronic oral administration of L-dopa plus carbidopa alone, or with co-administration of the peripheral COMT inhibitor entacapone, to normal macaque monkeys. entacapone catechol-O-methyltransferase Homo sapiens
2 Repeated high dose L-dopa administration was shown to induce marked dyskinesias in monkeys with an intact nigrostriatal system, and the threshold for dyskinesia expression was increased by peripheral catechol-O-methyltransferase inhibition with entacapone. entacapone catechol-O-methyltransferase Homo sapiens
