CAS 303-53-7: Cyclobenzaprine

Description: Cyclobenzaprine is a muscle relaxant commonly used to relieve muscle spasms associated with acute musculoskeletal conditions. It is classified as a tricyclic amine and has a chemical structure that includes a bicyclic ring system. The substance is typically administered orally and is known for its sedative properties, which can lead to drowsiness in some patients. Cyclobenzaprine works by acting on the central nervous system, specifically by inhibiting the reuptake of norepinephrine and serotonin, which helps to reduce muscle tone and alleviate pain. Its pharmacological effects generally begin within an hour of administration and can last for several hours. The substance is not recommended for long-term use due to potential side effects, including dry mouth, dizziness, and fatigue. Additionally, it may interact with other medications, particularly those that also depress the central nervous system. Cyclobenzaprine is contraindicated in patients with certain medical conditions, such as hyperthyroidism or heart block, and should be used with caution in the elderly or those with liver impairment.
