Cyclobenzaprine, a muscle relaxant commonly prescribed for muscle spasms, has shown significant promise in reducing pain and improving sleep quality. This medication is often used to treat conditions associated with acute musculoskeletal pain and is usually prescribed for short-term use. Understanding how cyclobenzaprine works and its benefits can help patients and healthcare providers make informed decisions about its use.Cyclobenzaprine works by influencing the central nervous system. It is structurally similar to tricyclic antidepressants, which allows it to inhibit the reuptake of norepinephrine and serotonin to some extent. However, its primary function as a muscle relaxant is due to its ability to block nerve impulses, or pain sensations, that are sent to the brain. This results in a reduction of muscle spasm and associated discomfort.
