Documented Uses

• Antidepressive Agents, Tricyclic; Muscle Relaxants, Central; Tranquilizing Agents
• Consumption (g per capita) in the USA (2002): 0.000978
• Cyclobenzaprine may be synthesized by Grignard addition of alpha-dimethylaminopropylmagnesium chloride to 10,11-dihydro-5H-dibenzo[a,d]cycloheptene-5-one, followed by elimination of water from the resulting tertiary carbinol.
• Cyclobenzaprine is a centrally acting skeletal muscle relaxant structurally related to tricyclic antidepressants. Cyclobenzaprine is a tricyclic amine salt that works in the central nervous system (CNS) as a depressant that reduces muscle hyperactivity. Clinical indications for cyclobenzaprine are described below.
• Cyclobenzaprine is a centrally acting muscle relaxant closely related to the tricyclic antidepressants. Despite its similarity to tricyclic antidepressants, there is little evidence that cyclobenzaprine causes liver injury.
• Breast Feeding; Lactation; Milk, Human; Muscle Relaxants, Central
