The cyclic AMP secondary messenger system is shown to be modulated by lithium. Lithium was found to increase the basal levels of cyclic AMP but impair receptor-coupled stimulation of cyclic AMP production. [119] It is hypothesized that the dual effects of lithium are due to the inhibition of G-proteins that mediate cyclic AMP production. [119]
Excessive levels of lithium can be harmful to the kidneys, and increase the risk of side effects in general. As a result, kidney function and blood levels of lithium are monitored in patients being treated with lithium. [2] Therapeutic plasma levels of lithium range from 0.5 to 1.5 mEq/L, with levels of 0.8 or higher being desirable in acute ...
Lithium is readily absorbed from the gastrointestinal tract. [5] It is distributed to the body with higher levels in the kidney, thyroid, and bone as compared to other tissues. Since lithium is almost exclusively excreted by the kidneys, people with preexisting chronic kidney disease are at high risk of developing lithium intoxication. [13]
The most commonly used classes of medications for these disorders are antidepressants, antipsychotics, and lithium. Unfortunately, these medications are associated with significant neurotoxicities. Psychiatric medications carry risk for neurotoxic adverse effects. The occurrence of neurotoxic effects can potentially reduce drug compliance.
Lithium intoxication can affect the central nervous system and renal system and can be lethal. [17] Over a prolonged period, lithium can accumulate in the principal cells of the collecting duct and interfere with antidiuretic hormone (ADH), which regulates the water permeability of principal cells in the collecting tubule.

The soft drink 7Up was originally named "Bib-Label Lithiated Lemon-Lime Soda" when it was formulated in 1929 because it contained lithium citrate. The beverage was a patent medicine marketed as a cure for hangover. Lithium citrate was removed from 7Up in 1948 [5] after the Food and Drug Administration banned its use in soda. [6]
Compounds containing metal ions can be used as medicine, such as lithium compounds and auranofin. [19] [20] Metal compounds and ions can also produce harmful effects on the body due to the toxicity of several types of metals. [18] For example, arsenic works as a potent poison due to its effects as an enzyme inhibitor, disrupting ATP production ...
Lithium forms salt-like derivatives with all halides and pseudohalides. Some examples include the halides LiF, LiCl, LiBr, LiI, as well as the pseudohalides and related anions. Lithium carbonate has been described as the most important compound of lithium. [100] This white solid is the principal product of beneficiation of lithium ores.
