Carisoprodol
Mechanism :
Carisoprodol is a central nervous system depressant that acts as a sedative and skeletal muscle relaxant. Rather than acting directly on skeletal muscle, carisoprodol interrupts neuronal communication within the reticular formation and spinal cord, resulting in sedation and alteration in pain perception. Its exact mechanism of action is not yet known.
