Also known as: Lithium Carbonate
LITHIUM CARBONATE (brand name: Lithium Carbonate) is a Mood Stabilizers. INDICATIONS Lithium carbonate extended-release tablets are indicated in the treatment of manic episodes of Bipolar Disorder. Bipolar Disorder, Manic (DSM-IV) is equivalent to Manic Depressive illness, Manic, in the older DSM-II terminology.

Concomitant use of naproxen with lithium can significantly increase serum lithium concentrations, leading to lithium toxicity. Patients may experience symptoms such as tremor, confusion, ataxia, and in severe cases, seizures or coma.
Mechanism
Naproxen, an NSAID, inhibits renal prostaglandin synthesis. Prostaglandins play a role in regulating renal blood flow and lithium excretion. Inhibition of prostaglandins by naproxen reduces renal lithium clearance, leading to increased lithium reabsorption and elevated serum levels.
Clinical Management
Avoid concomitant use if possible. If co-administration is necessary, closely monitor serum lithium levels, especially during initiation, dosage changes, or discontinuation of naproxen. Adjust lithium dose as needed and educate the patient on signs and symptoms of lithium toxicity.
Ibuprofen can significantly increase serum lithium levels, leading to an elevated risk of lithium toxicity. Patients may experience symptoms such as tremor, confusion, ataxia, slurred speech, lethargy, and in severe cases, seizures or coma.
Mechanism
NSAIDs like ibuprofen reduce renal blood flow and inhibit prostaglandin synthesis, which decreases lithium excretion by the kidneys. This leads to increased reabsorption of lithium in the renal tubules and higher systemic lithium concentrations.
Clinical Management
Concomitant use of ibuprofen and lithium should generally be avoided. If NSAID use is unavoidable, carefully monitor serum lithium levels, especially during initiation or dose changes of ibuprofen. Consider alternative analgesics that do not affect lithium clearance, such as acetaminophen.
Concomitant use of diclofenac with lithium can significantly increase serum lithium levels, leading to an elevated risk of lithium toxicity. Patients may experience symptoms such as tremor, confusion, ataxia, and in severe cases, seizures or coma.
Mechanism
Diclofenac, an NSAID, can reduce renal clearance of lithium by inhibiting prostaglandin synthesis, which affects renal blood flow and tubular reabsorption of lithium. This leads to decreased lithium excretion and increased serum concentrations.
Clinical Management
Avoid concomitant use if possible. If co-administration is necessary, closely monitor serum lithium levels, especially during initiation or dosage changes of diclofenac, and adjust lithium dose as needed. Monitor for signs and symptoms of lithium toxicity.
Concomitant use of furosemide with lithium can significantly increase serum lithium levels, leading to an elevated risk of lithium toxicity. Patients may experience symptoms such as tremor, confusion, ataxia, and in severe cases, seizures or coma.
Mechanism
Furosemide, a loop diuretic, can cause sodium and water depletion. The kidneys compensate by increasing proximal tubular reabsorption of sodium and, consequently, lithium. This reduced renal clearance of lithium leads to its accumulation.
Clinical Management
Avoid concurrent use if possible. If co-administration is necessary, closely monitor serum lithium levels, especially during initiation or dose changes of furosemide, and adjust lithium dosage as needed. Monitor for signs and symptoms of lithium toxicity and maintain adequate hydration.
