What Is Flexeril?

How Does Flexeril Work?

Flexeril is a centrally acting skeletal muscle relaxant structurally related to tricyclic antidepressants. It relieves skeletal muscle spasms of local origin without interfering with muscle function. Research indicates that it primarily operates within the central nervous system in the brain stem.

Flexeril does not work directly on skeletal muscle or the neuromuscular junction, although an overlapping action on the spinal cord may contribute to its overall skeletal muscle relaxant activity.

Evidence implies that the resultant impact of a Flexeril dose is a decline of tonic somatic motor activity, affecting both gamma(γ) and alpha(α) motor systems. Additionally, recent research suggests that Flexeril is a (5-HT2) receptor antagonist, meaning this additional action is responsible for its antispasmodic effect.

Flexeril is an antispasmodic drug that effectively treats muscle spasms, reduces local pain and tenderness, and increases range of motion in acute, painful musculoskeletal conditions.4

How Long Does Flexeril Stay in Your System?

The question, how long does Flexeril stay in your system? is commonly asked when trying to mislead a cyclobenzaprine drug test, which is often associated with misuse and potential addiction. Please note that this information is purely informative and is in no way intended to assist in the misleading of a Flexeril narcotic drug test.

As an estimate, after taking a dose of Flexeril, it should be out of the system within 5.5 days to 16.5 days. Thus, the Flexeril half-life is between one and three days. This is the time it takes for the body to reduce the plasma drug levels by half. Flexeril is therefore considered to be eliminated slowly from the body.

It usually takes around 5.5 x half-life for a drug to be eliminated from the system. For Flexeril, one would calculate (5.5 x 1) 5.5 days to (5.5 x 3) 16.5 days.7
