Study on the protection of CDP-choline against nicotine intoxication.
Cytidine diphosphate choline (CDP-choline, citicoline, Somazina) was orally administered to a group of mice at a dose of 1 g/kg for 4 days. Simultaneously, another group of mice were treated under similar conditions with 0.25% agar suspension. Then, animals were distributed into subgroups of 10 mice each and intravenous increasing doses of nicotine bitartrate were administered. By comparing the toxicity induced by nicotine in the animals receiving CDP-choline with that in animals receiving agar solution, a remarkable difference of the LD50 was observed between both groups.
