Rilutek Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Rilutek is a brand name. Its generic name is Riluzole.

Introduction

Rilutek is an anti-glutamate agent which has been approved in various countries for the treatment of neurological disorders like amyotrophic lateral sclerosis (ALS) and also for Parkinson's disease and Alzheimer's disease. It has been found to have neuroprotective as well as neuromodulatory actions. In the treatment of ALS, it is used to slow the progression of the disease and delay the decrease in the function of motor neurons.

Uses

Rilutek is used to treat Amyotrophic Lateral Sclerosis (ALS) or Lou Gehrig's disease, which is a fatal progressive neurodegenerative disease. It has been found to slow the progression of the disease and decrease the decrease in function of motor neurons. Rilutek also has potential to be used in the treatment of Parkinson's disease, Alzheimer's disease, and Huntington disease.

Mechanism of Action

Rilutek blocks the action of glutamate, a neurotransmitter which can lead to neuronal damage when present in excess, by inhibiting its action and binding to glutamate receptors in the brain. By blocking the action of glutamate, riluzole helps to protect the neurons from further damage, which could slow the progression of ALS and delay the decrease in motor neuron function. Rilutek has also been found to modulate the activity of gamma-aminobutyric acid (GABA), a neurotransmitter involved in motor neuron activity.
