Grandaxin

Grandaxin - During pregnancy | Use | Dose

Grandaxin is a medicine containing the active substance Tofisopam in a dose of 50 mg, and belongs to the family of drugs called benzodiazepines. Although chemically there is very little differences from other benzodiazepines (different position of nitrogen atoms), it manifests quite different pharmacological effects than other benzodiazepines. Unlike other benzodiazepines, it does not exhibit a sedative effect, anticonvulsant effect and muscle-relaxation effect.1

It can be obtained only by prescription, although it is not associated with physical or psychological dependence.

It is used to treat mental disorders associated with increased tension, anxiety, loss of energy, loss of motivation, and depressed mood.

It can also be used to alleviate the symptoms of alcohol withdrawal.

It has no effect on muscle relaxation, and therefore it can be used in patients who have myasthenia gravis.
