What is Baclofen?
Baclofen is a skeletal muscle relaxant that likely works by decreasing key neurotransmitters. It is often sold under the trade name Lioresal.
Baclofen is taken by mouth or can be injected directly into the spine.
What is Baclofen Used For?
Baclofen is used for the treatment of muscle spasticity (involuntary muscle movement) typically associated with spinal cord injuries or multiple sclerosis.
It can be helpful at the end of life for patients that develop hiccups or muscle spasms.
How Does Baclofen Work?
It is thought that baclofen works by inhibiting certain reflexes at the spinal level, meaning it blocks them at the spinal cord. Like most muscle relaxants, it reduces the transmission of messages between nerve cells. This allows the muscles to contract less.
It may also activate key receptors in the brain to create a feeling of relaxation and reduced anxiety.
How Long Does it Take for Baclofen to Work?
Many people feel the effect of the medication after about 30 minutes.
