Cyclobenzaprine is a medication primarily used as a muscle relaxant to treat muscle spasms, pain, and discomfort associated with musculoskeletal conditions. Understanding its proper use, dosage, and potential side effects is crucial for safe and effective treatment.
Cyclobenzaprine, also known by its brand names
Flexeril® and Amrix®, is a prescription medication classified as a muscle relaxant. It is a tricyclic compound that was initially developed and approved for use in the 1970s.
Cyclobenzaprine works by blocking nerve impulses that cause muscle spasms, helping to relieve muscle stiffness and pain. The primary medical use of
Cyclobenzaprine is to treat muscle spasms and relieve muscle pain and discomfort associated with various musculoskeletal conditions, such as:
Cyclobenzaprine is often used in combination with rest, physical therapy, and other non-drug measures to manage muscle spasms and promote healing. Source:

Cyclobenzaprine is rapidly absorbed after oral administration, with peak plasma concentrations occurring within 3-4 hours. It is extensively metabolized in the liver by the cytochrome P450 enzyme system and has a half-life of approximately 18 hours. The muscle relaxant effects of
Cyclobenzaprine are thought to be mediated through its central nervous system activity, particularly in the brainstem and spinal cord. Its mechanism of action involves modulation of various neurotransmitters, including serotonin, norepinephrine, and possibly others. Source:
