Anticonvulsant drugs work by a range of mechanisms, several acts by modulating glutamate outflow. Topiramate interacts with voltage-gated calcium channels and thereby modulates glutamate release from axon terminals. Controlled trials have suggested modest benefit from topiramate; this may be greater for compulsions than for obsessions [73, 74].

Se hela listan på psychonautwiki.org Brain glutamate is thought to mediate symptoms in schizophrenia due to the influence of glutamate neurons on the dopaminergic transmission in the brain. It might be possible to decrease negative Glutamatergic drugs have been found to work in some but not in all studies. These compounds seemed to work better with treatment- resistant schizophrenia patients, Results: Most drugs acting at glutamatergic receptors showed biochemical effects indicative of antidepressant activity in both clinical and preclinical studies. Recent neuroimaging and genetic contributions also confirm the antidepressant properties of these medications. All drugs of abuse appear to modulate glutamatergic transmission, albeit by different mechanisms, and this modulation of glutamate transmission is believed to result in long-lasting neuroplastic changes in the brain that may contribute to the perseveration of drug-seeking behavior and drug-associated memories. These observations have supported the hypothesis that any drug or disease that reduces glutamatergic transmission at the NMDA site could be associated with psychosis. Conversely, both the conventional antipsychotic haloperidol and the atypical clozapine mediate gene expression (c-fos) via intracellular regulation of NMDA receptors in the striatum.

Administration of this drug blocks the conversion of GABA to succinic semialdehyde, resulting in high intracellular GABA concentrations and increased synaptic GABA release. Like the effect of tiagabine, enhancement of GABA receptor function by γ-vinyl GABA is not selective because GABA concentrations are increased wherever GABA is released, including the retina.

Specifically, those glutamatergic medications targeting NMDA receptors by inhibiting the release of neurotransmitters or modulating its post-synaptic responses may serve as … 2012-02-01 2011-02-01 2020-05-13 Dysregulation of the glutamatergic system is sufficient to alter drug-induced behaviors even in the face of normal dopaminergic responses to cocaine in the NAcc (Morishima et al., 2005).

Conversely, both the conventional antipsychotic haloperidol and the atypical clozapine mediate gene expression (c-fos) via intracellular regulation of NMDA receptors in the striatum.

Scientists proposed that specific antagonists can act on GABAergic interneurons, enhancing cortical inhibition and preventing excessive glutamatergic transmission associated with schizophrenia. These and other atypical antipsychotic drugs can be used together to inhibit excessive excitability in pyramidal cells, decreasing the symptoms of schizophrenia. Currently available antipsychotic drugs target dopaminergic neurotransmission. Many patients do not respond fully to these treatments, and there has been considerable effort to investigate alternative targets.
