Lubeluzole for acute ischaemic stroke.

Experimental studies have shown that ischaemic insults cause excess release of excitatory amino acid (EAA) neurotransmitters, particularly glutamate. Glutamate re-uptake is impaired under ischaemic conditions. In preclinical models of stroke, antagonists of excitatory amino acids or of glutamate release protect against ischaemic injury, even when administered after the ischaemic insult. Lubeluzole is a benzothiazole derivative that has shown neuroprotective properties in different experimental models inhibiting glutamate release, nitric oxide (NO) synthesis and blocking voltage-gated Na+ and Ca2+ ion channels.
