BACKGROUND: CDP-choline (citicholine; cytidine-5'-diphosphate choline) is an endogenously produced nucleotide which, when injected intracerebroventricularly, exerts an antinociceptive effect in acute pain models mediated by central cholinergic mechanisms and alpha 7 nicotinic acetylcholine receptors (alpha 7nAChR). Previous reports also suggest that the peripheral cholinergic system has an antiinflammatory role mediated by alpha 7nAChRs on macrophages.
