GABLOFEN (baclofen)
Gablofen is indicated for the management of severe spasticity of cerebral or spinal origin in adults and pediatric patients aged four years and older. It is reserved for patients who do not respond to oral baclofen or who experience intolerable central nervous system side effects at effective oral doses. For spasticity resulting from traumatic brain injury, patients must wait at least one year after the injury before beginning therapy. Prior to the implantation of a pump for long-term infusion, patients must demonstrate a positive clinical response to an intrathecal screening dose.
How GABLOFEN Works
Gablofen is a structural analog of the inhibitory neurotransmitter GABA and acts as a GABAB receptor agonist. It reduces muscle spasticity by inhibiting both monosynaptic and polysynaptic reflexes at the spinal level, likely by decreasing the release of excitatory neurotransmitters from primary afferent terminals. Delivering the medication directly into the intrathecal space achieves effective cerebrospinal fluid (CSF) concentrations with plasma levels approximately 100 times lower than those resulting from oral administration, thereby reducing systemic side effects.

BOXED WARNING WARNING: DO NOT DISCONTINUE ABRUPTLY Abrupt discontinuation of intrathecal baclofen, regardless of the cause, has resulted in sequelae that include high fever, altered mental status, exaggerated rebound spasticity, and muscle rigidity, that in rare cases has advanced to rhabdomyolysis, multiple organ-system failure and death. Prevention of abrupt discontinuation of intrathecal baclofen requires careful attention to programming and monitoring of the infusion system, refill scheduling and procedures, and pump alarms. Patients and caregivers should be advised of the importance of keeping scheduled refill visits and should be educated on the early symptoms of baclofen withdrawal. Special attention should be given to patients at apparent risk (e.g., spinal cord injuries at T-6 or above, communication difficulties, history of withdrawal symptoms from oral or intrathecal baclofen). Consult the technical manual of the implantable infusion system for additional post-implant clinician and patient information [ see Warnings and Precautions (5.4) ].
