Answer to Question 1

Correct Answer: 1,2,5
Rationale 1: Metaxalone (Skelaxin) is ineffective in the treatment of spasticity-related neurologic disorders.
Rationale 2: Chlorzoxazone (Parafon Forte) is ineffective in the treatment of spasticity related to neurodegenerative disorders.
Rationale 3: Carisoprodol (Soma) is effective in relieving the pain, muscle spasms, and spasticity associated with cerebral palsy and is dosed three times a day.
Rationale 4: Baclofen (Lioresal) is effective in reducing muscle spasticity and can be delivered intrathecally.
Rationale 5: Tizanidine (Zanaflex) is used for muscle spasticity but has a short half-life and must be dosed every 68 hours.
Global Rationale: Metaxalone (Skelaxin) is ineffective in the treatment of spasticity-related neurologic disorders. Chlorzoxazone (Parafon Forte) is ineffective in the treatment of spasticity related to neurodegenerative disorders. Carisoprodol (Soma) is effective in relieving the pain, muscle spasms, and spasticity associated with cerebral palsy and is dosed three times a day.

Tizanidine (Zanaflex) is used for muscle spasticity but has a short half-life and must be dosed every 68 hours.

Answer to Question 2

Correct Answer: 1
Rationale 1: Dantrolene is a direct-acting skeletal muscle relaxant that interferes with the release of calcium ions that produce hypermetabolism and intense muscle rigidity in malignant hyperthermia.
Rationale 2: Baclofen is a centrally acting muscle relaxant.
Rationale 3: Tizanidine is a centrally acting muscle relaxant.
Rationale 4: Orphenadrine is a centrally acting muscle relaxant.
Global Rationale: Dantrolene is a direct-acting skeletal muscle relaxant that interferes with the release of calcium ions that produce hypermetabolism and intense muscle rigidity in malignant hyperthermia. Baclofen is a centrally acting muscle relaxant. Tizanidine is a centrally acting muscle relaxant. Orphenadrine is a centrally acting muscle relaxant.
