| 毒性 | An element used clinically
as one of its salts. It is effective against both mania and
depression. Despite its effectiveness, there are no clear
mechanisms that have been directly related to its therapeutic
effectiveness although its inhibition of the formation of inositol
from inositol phosphate is thought to be important. At therapeutic
concentrations, lithium causes almost no discernible
psychotropic effects in healthy humans. The major complaints
when the serum concentrations of the drug are carefully monitored
include slight muscular weakness, thirst, and excessive
urination. The major difficulty with lithium is that a fairly high
concentration of the ion is needed in the blood
(0.5_x0002_1.0 mmol/L) for maintenance, higher for acute mania.
Toxic symptoms (which can involve many physiological
symptoms) may occur, however, at doses of 1.5 mmol/L or
higher. This low therapeutic index is indicative of the need for
regular monitoring of lithium concentrations in the serum. |
