Riluzole is primarily prescribed for which condition?

• A. Amyotrophic lateral sclerosis.
• B. Multiple sclerosis.
• C. Parkinson disease.
• D. Guillain-Barré syndrome.

Answer: (A)

Riluzole is used to slow progression in amyotrophic lateral sclerosis by reducing glutamate-induced excitotoxicity in motor neurons. In ALS, excessive glutamate signaling can cause calcium overload and neuron death; riluzole helps by lowering glutamate release and dampening neuronal excitability, which modestly slows decline and can extend survival in some patients. This is why the best answer is amyotrophic lateral sclerosis. The other conditions—multiple sclerosis, Parkinson disease, and Guillain-Barré syndrome—have different underlying mechanisms and standard treatments, and riluzole is not a typical therapy for them.
