What is lithium carbonate sustained-release tablet?

Lithium carbonate sustained-release tablets are commonly used in psychiatry, primarily for the treatment and prevention of manic and depressive episodes in bipolar disorder. The details are as follows:

Lithium carbonate sustained-release tablets are a commonly used mood stabilizer, mainly indicated for manic episodes and also effective in preventing recurrence of bipolar disorder. The drug works by regulating neurotransmitter levels in the central nervous system, stabilizing mood fluctuations, and reducing the frequency and severity of manic symptoms such as excessive excitement, talkativeness, impulsivity, and irritability. Regular monitoring of serum lithium levels is required during treatment, as the therapeutic dose is close to the toxic dose. High concentrations may cause adverse effects such as nausea and hand tremors, while low concentrations may fail to achieve therapeutic efficacy.

Patients should maintain adequate fluid intake during treatment, aiming for approximately 2000 mL of water per day to promote drug metabolism and excretion. A light and balanced diet is recommended, avoiding long-term low-salt intake, which could affect the stability of serum lithium levels. Medication should be taken at fixed times each day; dosage adjustments or discontinuation should not be done arbitrarily. Close attention should be paid to emotional changes and physical reactions. If symptoms such as fatigue, vomiting, or unsteady gait occur, prompt medical evaluation is necessary. Maintaining regular sleep patterns, avoiding late nights and excessive fatigue, provides a solid foundation for emotional stability.
