Baclofen (Lioresal) is best classified as what type of medication?

Explanation:
Baclofen works as a muscle relaxant. It acts centrally on the spinal cord as a GABA-B receptor agonist, which dampens excitatory signals to motor neurons and lowers muscle tone to alleviate spasticity. This mechanism and its primary use—reducing spasticity in conditions like multiple sclerosis or spinal cord injury—are different from antipsychotics (which target psychosis), antidepressants (mood disorders), or anxiolytics (anxiety). So the best classification is a muscle relaxant, rather than a medication for psychosis, mood, or anxiety.
