The elimination half-life of lithium was investigated in 55 patients on long-term treatment in 1980, when their mean treatment time was 7.5 years. Twenty-seven of the patients were reinvestigated 7 years later, at which point their mean treatment time was 15 years. An approximate method for determin

β¦ Synopsis
Thyroid iodine release measured by the double isotope method of Nicoloff was studied in patients with manic-depressive illness before, during and after treatment with lithium carbonate. The urinary lZSI/ZalI isotope ratio was measured following administration of Nal~SI and z3~I-thyroxine. In three of four subjects, lithium caused a transient decrease in diurnal variation and a temporary reduction in the normal increase of the 1~5I/~3zI ratio during the first week of therapy or after alithium dose increase. In addition, in two of three subjects, a rebound increase in the isotope ratio occurred following cessation of lithium administration. These changes most likely represent a direct inhibitory effect of lithium on the thyroid iodine release process.

The plasma thyrotropin (TSH) and prolactin (PRL) responses to thyrotropin releasing hormone (TRH) were studied before and during lithium treatment for 3 -4 weeks in 6 patients with'manic states and 8 control subjects.
