It is widely prescribed to manage bipolar spectrum disorders by stabilizing mood fluctuations and preventing recurrence of manic or depressive episodes. Its sustained benefits make it suitable for long-term maintenance therapy.

- Sleep & Mental Health > Bipolar Disorder Lithosun 300 is a cornerstone in the treatment of bipolar disorder, offering control over manic and hypomanic episodes and reducing the risk of relapse. It is effective both in acute management and as a preventive maintenance therapy. > Depression, Anxiety, PTSD As an adjunct to antidepressants, Lithosun 300 helps regulate emotional volatility in patients with treatment-resistant depression, chronic anxiety, and PTSD.

Lithium carbonate works by modulating neurotransmitter activity and stabilizing neuronal excitability. It inhibits inositol monophosphatase and modulates second-messenger systems, which normalizes serotonin and norepinephrine transmission to reduce extreme mood shifts.
