The effects of the antiparkinsonian drugs budipine and biperiden on spontaneous and electrically evoked release of dopamine (DA), acetylcholine (ACh), GABA or noradrenaline (NA) were studied in caudate nucleus or cortex slices, respectively, of the rabbit brain. Whereas both drugs (1-10 microM) strongly increased spontaneous [3H]outflow in caudate nucleus slices preincubated with [3H]DA, budipine inhibited but biperiden facilitated the evoked DA release. In the presence of the DA-reuptake… Expand
Effects of the antiparkinsonian drug budipine on central neurotransmitter systems.
TLDR
The present data suggest that budipine acts by blocking muscarinic and NMDA transmission while facilitation of dopaminergic transmission does not appear to contribute to its in vivo action. Expand
The antiparkinsonian drugs budipine and biperiden are use-dependent (uncompetitive) NMDA receptor antagonists.
TLDR
It is concluded that budipine and biperiden are use-dependent (uncompetitive) antagonists at the NMDA receptor, binding to the receptor-linked ion channel, but probably not to the MK-801 binding site. Expand
Properties of 3,4-diaminopyridine-evoked dopamine and acetylcholine release in rabbit caudate nucleus slices: involvement of facilitatory adenosine A2 receptors or nitric oxide?
TLDR
It is concluded, that 3,4-DAP-evoked 3H-overflow from rabbit caudate nucleus slices preincubated with tritiated dopamine or choline, represents a simple and useful in vitro model for action potential-induced DA or ACh release, respectively. Expand
Multiple mechanisms of action: the pharmacological profile of budipine.

TLDR
By means of these multiple mechanisms, budipine might correct the imbalance of striatal output pathways by restoring DA levels in the striatum, and positively influence the secondary changes in other transmitter systems (glutamate, acetylcholine, GABA) observed in Parkinson's disease. Expand
Microdialysis study of the effects of the antiparkinsonian drug budipine on L‐DOPA‐induced release of dopamine and 5‐hydroxytryptamine by rat substantia nigra and corpus striatum
TLDR
It is concluded that budipine, at a therapeutically relevant dose, potentiates the release of dopamine newly synthesised from L‐DOPA from either end of the nigrostriatal dopamine axis. Expand
Clinical efficacy of budipine in Parkinson's disease.
TLDR
Budipine induced a relevant additional positive effect in patients with an optimal dopaminergic therapy based on levodopa and dopamine agonists, such as bromocriptine, and that the long-term application of budipine may induce alevodopa-sparing effect. Expand
Antiglutamatergic drugs in the treatment of Parkinson's disease.
TLDR
Amantadine is the only antiglutamatergic agent used in the management of PD patients and is particularly useful for the treatment of levodopa-induced dykinesias. Expand
The antiparkinsonian drug budipine stimulates the activity of aromatic L‐amino acid decarboxylase and enhances L‐DOPA‐induced dopamine release in rat substantia nigra
TLDR
It is suggested that the beneficial effects of budipine, when used as an adjunct to L‐DOPA therapy of Parkinson's disease, may be due to an increase in the bioconversion of L‐ DOPA with a consequent rise in synaptic dopamine. Expand
Budipine is a low affinity, N-methyl-d-aspartate receptor antagonist: patch clamp studies in cultured striatal, hippocampal, cortical and superior colliculus neurones
TLDR
Budipine, memantine and amantadine had similar effects against NMDA-induced currents in cultured hippocampal, cortical and superior colliculus neurones, although amantADine was somewhat more potent in cultured striatal neurones. Expand
Effect of cytochrome P450 2D1 inhibition on hydrocodone metabolism and its behavioral consequences in rats.
TLDR
Data suggest that differences in CYP2D6 phenotype will have limited influence on the drug response to hydrocodone after nonoral administration, verified in a study showing that inhibition of hydrocODone biotransformation to hydromorphone does not affect measures of abuse liability. Expand
