Mechanism of Action
The exact mechanism of action of lithium carbonate is unknown, however it is believed to affect neurotransmitters such as norepinephrine, serotonin, and dopamine. Lithium may also act on other areas such as enzymes involved in signal transduction pathways, and may affect the activity of neurons in certain areas of the brain involved in mood regulation.
How Long Does It Take to Work?
Lithium carbonate usually begins to work within 1-2 weeks of starting treatment, but its full effect can take up to 8 weeks, or possibly even longer. It is important to talk to your doctor if you feel that the medication is not working for you.
Absorption
Lithium carbonate is rapidly and completely absorbed from the gut, with peak plasma concentrations occurring ~1-2 hours after an oral dose. The bioavailability of lithium carbonate is not affected by food.
Route of Elimination
Lithium carbonate is rapidly absorbed from the gut and is primarily eliminated through the kidneys in the urine. Approximately 90% of a dose is excreted in the urine within 24 hours.
Dosage
The usual adult dose of lithium carbonate for the treatment of bipolar disorder is 600-1500mg per day divided into 2-3 doses. The dose should be individualized according to patient response, blood levels, and side effects. It is important to follow your doctor’s instructions closely when taking this medication.
Administration

Although most side effects are mild and can usually be managed by adjusting the dose or changing medication, other serious effects can occur and should be reported to your doctor immediately.
Toxicity
The therapeutic range for lithium carbonate levels in the blood is 0.6-1.2 mM/L. Toxic effects may start to occur at plasma concentrations of 1.5 mM/L or higher, and may lead to seizures, coma, and even death at very high levels.
Precautions
Lithium carbonate should be used with caution in patient’s with kidney or thyroid disease, heart disease, or people taking diuretics.
