Baclofen is primarily used to treat spasticity, which is a condition characterized by abnormal muscle tightness and stiffness that can occur due to neurological disorders, such as multiple sclerosis or spinal cord injuries. The medication works as a muscle relaxant by acting on the central nervous system. It reduces muscle spasms and improves overall movement by inhibiting excessive excitatory signals in the spinal cord.

Unlike the other options, which relate to different physical conditions, spasticity specifically involves an involuntary contraction of muscles, making baclofen's mechanism of action particularly suited to alleviate the symptoms of this condition. Cramps, swelling, and fatigue are addressed with different therapies or medications that target their specific underlying mechanisms, but they do not respond effectively to baclofen in the way that spasticity does.
