Mechanism & Pharmacology

Lithium carbonate works primarily by modulating the balance of neurotransmitters in the brain. It reduces excessive excitatory neurotransmission, helping to stabilise mood. When lithium enters the body, it influences sodium transport in nerve and muscle cells, thus stabilising the mood and reducing the frequency of episodes in bipolar disorder.

Clinical terms

Understanding some technical terminology can shed light on lithium’s pharmacodynamics:

• Pharmacodynamics: The study of how drugs affect the body.
• Neurotransmitters: Chemicals that transmit signals in the nervous system.
• Excitatory neurotransmission: The process promoting nerve signal transmission, often excessive in mood disorders.

In essence, by inhibiting the overactivity of certain brain signals, lithium helps maintain a more stable emotional state.

Indications & Off-Label Uses

Lithium carbonate is primarily FDA-approved for the acute treatment of manic episodes in bipolar disorder and for maintenance therapy to prevent their recurrence. This is emphasised in its TGA-approved indications for managing both acute and chronic presentations of the condition.

Approved indications by TGA

The Therapeutic Goods Administration (TGA) recognises lithium's effectiveness in treating acute manic episodes in individuals diagnosed with bipolar I disorder, applicable in both adults and children aged seven and above.

Off-label uses in Australian clinical practice

Beyond its approved uses, lithium carbonate has gained traction in Australian clinical settings for various off-label applications. It is sometimes prescribed in treating recurrent depression, cluster headaches, and certain types of aggression. Prescribers consider these options based on individual patient needs and current research supporting such uses.

Key Clinical Findings
