    1. Severe muscle spasticity (e.g. spinal cord injury, Cerebral Palsy, Multiple Sclerosis)
    2. Alcohol Withdrawal
  3. Pharmacology
    1. Baclofen is a Skeletal Muscle Relaxant that binds GABA B receptors
      1. Baclofen hyperpolarizes afferent nerve fibers
        1. Blocks presynaptic Calcium influx
        2. Blocks presynaptic Potassium efflux
      2. Inhibits spinal cord reflexes
      3. Reduces muscle spasticity
    2. Oral Baclofen does not cross blood brain barrier well
      1. Requires intolerable oral doses to offer effect
    3. Instead, Baclofen is typically used via Baclofen Intrathecal Pump
      1. Intrathecal Baclofen has fewer side effects and may be used at low dose
  4. Dosing
    1. Baclofen 50-100 mcg/day via Intrathecal Pump (up to 900 mcg) and slowly titrate to effect
    2. Small dose modifications can have significant effects on patient findings (due to direct CSF drug delivery)
    3. Taper off over 1-2 weeks (risk of Hallucinations, Seizures if abruptly stopped)

  5. Complications
    1. Baclofen Withdrawal

Definition (CHV) a drug used to treat spasm caused by back injury
Definition (MSH) A GAMMA-AMINOBUTYRIC ACID derivative that is a specific agonist of GABA-B RECEPTORS. It is used in the treatment of MUSCLE SPASTICITY, especially that due to SPINAL CORD INJURIES. Its therapeutic effects result from actions at spinal and supraspinal sites, generally the reduction of excitatory transmission.
Definition (NCI) A synthetic chlorophenyl-butanoic acid derivative used to treat spasms due to spinal cord damage and multiple sclerosis, muscle-relaxing Baclofen acts as a gamma-aminobutyric acid (GABA) agonist specific for GABA-B receptors. It acts at spinal and supraspinal sites, reducing excitatory transmission. (NCI04)
Definition (NCI_NCI-GLOSS) A drug that is used to treat certain types of muscle spasms and is being studied in the treatment of liver cancer. Baclofen relaxes muscles by blocking certain nerve receptors in the spinal cord. It is a type of antispasmodic.
