Mechanism of Action
Lioresal (baclofen) is a medication used to treat muscle spasms and stiffness caused by multiple sclerosis or spinal cord injury. It works by blocking certain nerve signals in the spinal cord and brain that cause muscles to contract.
Lioresal works by blocking the action of a neurotransmitter called gamma-aminobutyric acid (GABA) in the spinal cord and brain. GABA is a neurotransmitter that inhibits muscle contractions. By blocking the action of GABA‚ Lioresal reduces muscle spasms and stiffness.
Specifically‚ Lioresal binds to GABAB receptors in the spinal cord and brain. GABA
B receptors are inhibitory receptors that‚ when activated‚ reduce the release of excitatory neurotransmitters‚ such as glutamate. Glutamate is a neurotransmitter that excites muscles and causes them to contract. By reducing the release of glutamate‚ Lioresal reduces muscle spasms and stiffness.
Lioresal also has some effects on other neurotransmitters‚ such as dopamine and serotonin. However‚ the exact mechanism of action of Lioresal is not fully understood.
Lioresal is effective in reducing muscle spasms and stiffness. It can improve mobility‚ reduce pain‚ and prevent contractures. Lioresal is generally well-tolerated‚ but side effects can include drowsiness‚ dizziness‚ nausea‚ and weakness.
Lioresal is not a cure for multiple sclerosis or spinal cord injury‚ but it can help to manage the symptoms of these conditions and improve quality of life.
