Lithium therapy

Abstract

Since the introduction of lithium therapy 30 years ago it has become a major weapon in psychiatrists' armamentarium. It is the drug of first choice for the prevention of recurrent mood disorders, and it is estimated that about one person in every thousand people in Britain receives lithium at any one time. It therefore behoves doctors to be familiar with its use. This article is not a comprehensive account of the pharmacology of lithium (for this the reader is referred to Johnson (1987) and Peet & Pratt (1993)) but concentrates on its clinical use in practice and some less well known, but important, phenomena.
