The monoamine reuptake inhibitor BTS 74 398 fails to evoke established dyskinesia but does not synergise with levodopa in MPTP-treated primates.

Long-term treatment of Parkinson's disease (PD) with levodopa (L-dopa) induces dyskinesia that, once established, is provoked by each dose of L-dopa or a dopamine (DA) agonist. In contrast, monoamine reuptake inhibitors may reverse motor deficits in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated primates without provoking established involuntary movements. We now examine whether the potent monoamine reuptake blocker BTS 74 398 induces established dyskinesia in MPTP-treated common marmosets primed previously with L-dopa and whether co-administration of BTS 74 398 with L-dopa potentiates motor behaviour and dyskinesia induced by acute L-dopa treatment. Administration of BTS 74 398 (2.5, 5.0, or 10.0 mg/kg, p.o.) in MPTP-treated common marmosets increased locomotor activity and reduced motor disability in a dose-related manner but did not provoke involuntary movements. BTS 74 398 (2.5, 5.0, or 10.0 mg/kg p.o.) co-administered with a threshold dose of L-dopa (2.5 mg/kg p.o.) did not evoke a motor response or induce dyskinesia. Similarly, concomitant administration of BTS 74 398 (5.0 mg/kg p.o.) with a submaximal L-dopa dose (12.5 mg/kg p.o.) did not potentiate the motor response produced by L-dopa alone and there was no alteration in the dyskinesia provoked by L-dopa challenge. BTS 74 398 reverses motor abnormalities in MPTP-treated marmosets without evoking established dyskinesia but no additive improvement occurs when administered in combination with L-dopa. The lack of synergy with L-dopa may suggest different sites of drug action.[1]
