Which is more sedating
Skeletal muscle relaxants are commonly used drugs prescribed for the treatment of muscle spasms and discomfort.
Muscle relaxants are not really a class of drugs, but rather a group of different drugs that each has an overall sedative effect on the body.
Muscle relaxants treat both muscle spasm and spasticity.
These drugs relieve muscle spasms due to low back pain, neck pain, fibromyalgia, tension headaches.
The mechanisms of action of the medications in this class are widely varied and many are not thoroughly understood.
This review examines the efficacy, side effects, and safety of three commonly prescribed skeletal muscle relaxants metaxalone (Skelaxin), cyclobenzaprine (Flexeril), and carisoprodol (Soma).Carisoprodol acts on the spinal cord and subcortical levels of the brain to depress polysynaptic neuron transmission.Carisoprodol, cyclobenzaprine and metaxalone are not found to be effective in the treatment of spasticity associated with upper motor neuron syndromes.Cyclobenzaprine has also been studied in the treatment of fibromyalgia and migraine.
