Pregabalin and duloxetin in the treatment of neuropathic pain Review article
Main Article Content
Abstract
Neuropathic pain is generated by disturbing the peripheral function of nerve fibers, spinal cord or cerebral. A decreased threshold of excitation of nerve cells and mechanisms provoking spontaneous ectopic neuronal discharges have occurred. At the intercellular level, neuropathic pain depends on the increased glutamatergic activity induced by the nerve-damaging factor. At the subcellular level, a change in the constellation of transmembrane ion channels (especially sodium and calcium) is responsible for the reduction of cell excitation threshold. That’s why in the treatment of neuropathic pain there are used drugs that affect calcium channels (pregabalin) and noradrenergic and serotonin transmission. The paper presents the principles of treatment with both preparations.
