Grandaxin (Tofisopam)

Grandaxin (aka tofisopam)

Grandaxin (Tofisopam) is a benzodiazepine anxiolytic drug that is used in Russia and some European countries. Despite being a benzodiazepine derivative, pharmacological action of Grandaxin is differs from that of typical benzos because of the structural differences.

Grandaxin is a 2,3- benzodiazepine derivative and belongs to the novel class of drugs called homophthalazines. Tofisopam does not cause sedation or cognitive functions impairments; moreover, it may produce a moderate stimulative action, possibly by increasing the sensitivity of dopaminergic receptors.

The drug does not bind to benzodiazepine receptors, it is suggested that its anxiolytic effect is mediated through its effect on opioid signal transduction.

One of the most important advantages of Grandaxin over commonly used benzodiazepines is that Tofisopam does not form an addiction.
