Baclofen defined
Baclofen is a prescription-only medication that relaxes skeletal muscles by modulating spinal cord neurotransmission. It acts as a GABA-B receptor agonist to dampen excessive nerve signals that increase muscle tone and provoke spasms.
In Australia baclofen is most often prescribed as oral tablets. For very severe or treatment-resistant spasticity, intrathecal administration via an implanted pump is available through specialist services. See Equivalent Options and Similar Optional routes for device-based treatments and other therapies.

Prescribers commonly consider baclofen for patients with:
- Spasticity following spinal cord injury

- Diazepam - a benzodiazepine used for short term relief of severe muscle spasm; sedating and has dependence potential.
- Gabapentin or pregabalin - useful when neuropathic pain contributes to spasticity symptoms.
- Botulinum toxin injections - effective for focal spasticity and administered by specialists.
