Lithium Citrate is the citrate salt of lithium, a monovalent cation with antimanic activity. Although the exact mechanism is unclear, lithium might exert its mood-stabilizing effect via reduction of catecholamine concentration mediated through transneuronal membrane transport of sodium ion by sodium-potassium-stimulated adenosine triphosphatase (Na-K-ATPase). Alternatively, lithium may decrease cyclic adenosine monophosphate (cAMP) concentrations, which would desensitize hormonal-sensitive adenylyl cyclase receptors. Furthermore, lithium, in recommended dosage, blocks the activity of inositol-1-phosphatase, thereby resulting in the subsequent decrease of postsynaptic second messengers, diacylglycerol and inositol triphosphate, that contribute to chronic cell stimulation by altering electrical activity in the neuron.

4.2 Drug Indication

Lithium is used as a mood stabilizer, and is used for treatment of depression and mania. It is often used in bipolar disorder treatment.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Although lithium has been used for over 50 years in treatment of bipolar disorder, the mechanism of action is still unknown. Lithium's therapeutic action may be due to a number of effects, ranging from inhibition of enzymes such as glycogen synthase kinase 3, inositol phosphatases, or modulation of glutamate receptors.


5.2 Mechanism of Action

The precise mechanism of action of Li+ as a mood-stabilizing agent is currently unknown. It is possible that Li+ produces its effects by interacting with the transport of monovalent or divalent cations in neurons. An increasing number of scientists have come to the conclusion that the excitatory neurotransmitter glutamate is the key factor in understanding how lithium works. Lithium has been shown to change the inward and outward currents of glutamate receptors (especially GluR3), without a shift in reversal potential. Lithium has been found to exert a dual effect on glutamate receptors, acting to keep the amount of glutamate active between cells at a stable, healthy level, neither too much nor too little. It is postulated that too much glutamate in the space between neurons causes mania, and too little, depression. Another mechanism by which lithium might help to regulate mood include the non-competitive inhibition of an enzyme called inositol monophosphatase. Alternately lithium's action may be enhanced through the deactivation of the GSK-3B enzyme. The regulation of GSK-3B by lithium may affect the circadian clock. GSK-3 is known for phosphorylating and thus inactivating glycogen synthase. GSK-3B has also been implicated in the control of cellular response to damaged DNA. GSK-3 normally phosphorylates beta catenin, which leads to beta catenin degratation. When GSK-3 is inhibited, beta catenin increases and transgenic mice with overexpression of beta catenin express similar behaviour to mice treated with lithium. These results suggest that increase of beta catenin may be a possible pathway for the therapeutic action of lithium.
