| | Riluzole Usage And Synthesis |
| Description | Riluzole belongs to the derivative of benzothiazole with neuroprotective, potential anti-depressant and anxiolytic activities, which is used in the treatment of a certain type of nerve disease called amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease). It is effective to delay the onset of ventilator-dependence or tracheostomy in selected patients, slow down the deterioration of this disease and probably prolong survival by approximately two to three months. Besides, studies have proved that riluzole has anti-depressant activity for refractory depression and serves as an anxiolytic in the treatment of obsessive-compulsive disorder and generalized anxiety disorder.
However, riluzole does not cure the ALS and reverse nerve damage or muscle weakness. It is believed to function as an inhibitor of a natural substance called glutamate. It helps protect the nerves in the brain and spinal cord from too much of glutamate which may contribute to the nerve damage. Riluzole is available in both tablet and liquid form. The liquid formulation may be more suitable for patients with swallowing difficulties.

| | Description | Rilutek was launched in Germany, the UK and US (orphan drug status) for
treatment of amyotrophic lateral sclerosis (ALS) and is the first drug approved for this
indication. A one step synthesis from 4-(trifluoromethoxy)aniline provides a supply of
the compound. The source of its neuroprotective and anticonvulsant activity is not
clearly understood. It antagonizes excitatory amino acids and blocks presynaptic
release of glutamate, is an antagonist of NMDA-induced acetylcholine release and
inhibited glutamate and quisqualate induced increases in cGMP but does not bind to
NMDA or Kainic receptors. Rilutek has no affinity for glutamate, GABAbenzodiazepine,
glycine and adenosine receptors. It easily crosses the blood brain
barrier and depresses glutamatergic neurotransmission, stabilizes voltagedependent
Na channels in their inactive form and activates G-protein dependent processes. | | Chemical Properties | White Crystalline Solid | | Originator | Rhone-Poulenc Rorer (France) | | Uses | anticonvulsant, glutamate release inhibitor, anti-ALS | | Uses | A neuroprotective agent.
