3. Carisoprodol (Soma) dosed three times a day
4. Intrathecal baclofen (Lioresal)
5. Tizanidine (Zanaflex) dosed twice a day
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 6–8 hours.
