Although originally designed in 1962 to treat epilepsy, baclofen was not effective in treating this condition but instead was shown to reduce spasticity in selected patients. Baclofen was reintroduced in 1971 as a treatment for spasticity and was later approved by the FDA in 1977. Baclofen is used to manage severe muscle spasms of cerebral or spinal cord origins, including multiple sclerosis and traumatic brain injury.  Baclofen was investigated for use in alcohol dependence and withdrawal; however, evidence is limited and there is inconsistent evidence to suggest its clinical efficacy in managing alcohol dependence or withdrawal symptoms."}]
