Fixed combination of non-steroidal anti-inflammatory drug and muscle relaxant as the basis for rational therapy of pain syndromes: A review

Abstract

The incidence of pain in the lower back ranges from 10% to 25% of all cases of algia. 37–64.7% of the world's population have muscle spasms of varying severity during an exacerbation of pain. The problem of pain therapy is far from being solved. Achieving greater or equal pain relief can be achieved through combination drug therapy, where drugs have different mechanisms of action or combine pharmacokinetic properties to produce a synergistic effect. Fixed combinations of non-steroidal anti-inflammatory drugs and a muscle relaxant (chlorzoxazone 500 mg and ibuprofen 400 mg) are the basis of rational therapy, allowing them to achieve a number of clinical and pharmacological advantages.
