Cyclobenzaprine

Same class on both cards

Mechanism: Relieves skeletal muscle spasm of local origin without interfering with muscle function. Animal studies support a mainly central action rather than a direct action at skeletal muscle or the neuromuscular junction.

Only on the Cyclobenzaprine card: Used for — Short-term relief of muscle spasm from acute, painful musculoskeletal conditions, as an adjunct to rest and physical therapy · Common side effects — Dry mouth; Dizziness; Fatigue; Constipation; Somnolence · Warnings — Serotonin syndrome; TCA-like cardiovascular / CNS effects; Not recommended in elderly or hepatic impairment; The selected extended-release capsule is intended only for short periods, up to 2–3 weeks; effectiveness for central spasticity has not been established · Interactions — MAO inhibitors; Alcohol, barbiturates, CNS depressants; Tramadol

Baclofen

Same body system: Musculoskeletal

Mechanism: The precise mechanism is not fully known. Baclofen can inhibit monosynaptic and polysynaptic spinal reflexes, possibly by hyperpolarizing afferent terminals; supraspinal actions may also contribute.

On both cards: Common side effects — Drowsiness · Interactions — CNS depressants and alcohol

Only on the Baclofen card: Used for — Alleviation of reversible spasticity due to multiple sclerosis; May also be of value for patients with spinal cord injuries or other spinal cord diseases · Common side effects — Dizziness; Weakness; Fatigue · Warnings — Abrupt withdrawal: hallucinations, seizures; Neonatal withdrawal if used in pregnancy; Not for rheumatic muscle spasm

An item counts as shared only when both cards use the same wording. If a card does not list an item, that is not a statement that the effect never occurs.
