 Context examples 

The exact mechanism through which levetiracetam exerts its effects is unknown but does not involve inhibitory and excitatory neurotransmitter activity.

(Levetiracetam, NCI Thesaurus)

Excitatory amino acid transporter 2 (574 aa, ~62 kDa) is encoded by the human SLC1A2 gene.

(Excitatory Amino Acid Transporter 2, NCI Thesaurus)

Isoflurane may also both inhibit glutamatergic excitatory transmission by increasing glutamate re-uptake, and potentiate glycine receptor activity, which decreases motor function.

(Isoflurane, NCI Thesaurus)

Felbamate also has weak inhibitory effects on gamma-aminobutyric acid (GABA) receptor binding sites which may contribute to its inhibitory effect on neuronal excitatory.

(Felbamate, NCI Thesaurus)

The active metabolite does not interact with alpha-adrenergic, serotonergic, histaminergic and excitatory amino acid receptors and is eliminated via renal excretion.

(Fesoterodine, NCI Thesaurus)

This agent is a substrate for the production of both excitatory and inhibitory neurotransmitters (glutamate and GABA) and is also an important source of energy for the nervous system.

(Glutamine, NCI Thesaurus)

Although its exact mechanism of action is unknown, gabapentin appears to inhibit excitatory neuron activity.
