    Cytidine diphosphate choline (CDP-choline) demonstrated low acute toxicity in mice and rats across various administration routes. LD50 values were calculated using established statistical methods for mortality and error estimation.

    Area of Science:

    • Pharmacology
    • Toxicology
    • Neuroscience

    Background:

    • Cytidine diphosphate choline (CDP-choline), also known as citicoline, is a vital endogenous compound involved in phospholipid synthesis.
    • It is utilized therapeutically for neurological conditions, necessitating a thorough understanding of its safety profile.

    Purpose of the Study:

    • To evaluate the acute toxicity of a single dose of CDP-choline administered via different routes in rodent models.
    • To determine the median lethal dose (LD50) and associated standard error for CDP-choline.

    Main Methods:

    • Acute toxicity testing was performed on mice and rats.
    • Administration routes included oral, intravenous, intraperitoneal, and subcutaneous injections.
    • LD50 values were calculated using the cumulative Reed-Muench method for mortality and Pizzi's method for standard error.

    Main Results:

    • The study established LD50 values for CDP-choline across various administration routes in both mice and rats.
    • Results indicated a low order of acute toxicity for CDP-choline.

    Conclusions:

    • CDP-choline exhibits a favorable safety profile concerning acute toxicity.
    • The determined LD50 values provide crucial data for safe clinical use and further toxicological assessments.
