Prediction of dosage of lithium carbonate: use of a standard predictive method.

The nomogram developed by Cooper and associates used to predict the dose of Lithium Carbonate (Li+) which is needed to attain therapeutic Li+ concentrations has, in general, proven to be accurate and clinically useful. However, there may be some patients in whom the pharmacokinetic disposition of Li+ varies sufficiently so that accurate dosage predictions cannot be made; a report of one such patient is given.
