Lithium toxicity is closely related to serum lithium concentrations, and can occur at doses close to therapeutic concentrations. Facilities for prompt and accurate serum lithium determinations should be available before initiating treatment [see Dosage and Administration ( 2.3), Warnings and Precautions ( 5.1)] . WARNING: LITHIUM TOXICITY See full prescribing information for complete boxed warning. Lithium toxicity is closely related to serum lithium concentrations, and can occur at doses close to therapeutic concentrations. Facilities for prompt and accurate serum lithium determinations should be available before initiating therapy ( 2.3, 5.1).

Lithium is a mood-stabilizing agent indicated as monotherapy for the treatment of bipolar I disorder: Treatment of acute manic and mixed episodes in patients 7 years and older [see Clinical Studies ( 14 )] Maintenance treatment in patients 7 years and older [see Clinical Studies ( 14 )] Lithium is a mood-stabilizing agent indicated as monotherapy for the treatment of bipolar I disorder: Treatment of acute manic and mixed episodes in patients 7 years and older ( 1) Maintenance treatment in patients 7 years and older ( 1)

Recommended starting dosage for adults and pediatric patients over 30 kg ( 2.2): Tablets or Capsules: 300 mg, three times daily, or Oral Solution: 8mEq lithium (5 mL) three times daily Recommended starting dosage for pediatric patients 20 to 30 kg ( 2.2): Tablets or Capsules: 300 mg twice daily, or Oral Solution: 8mEq (5mL), twice daily Obtain serum lithium concentration assay after 3 days, drawn 12 hours after the last oral dose and regularly until patient is stabilized. Acute Manic or Mixed Episodes (patients 7 years and older): Titrate to serum lithium concentrations 0.8 to 1.2 mEq/L ( 2.2). Maintenance Treatment for Bipolar I Disorder (patients 7 years and older): Titrate to serum lithium concentrations 0.8 to 1 mEq/L ( 2.2). Pre-treatment Screening: Evaluate renal function, vital signs, electrolytes, thyroid function, concurrent medications, and pregnancy status ( 2.1). Mild to Moderate Renal Impairment (CLer 30 to 89 mL/min): Start with dosages less than those for patients with normal renal function, titrate slowly with frequent monitoring ( 2.5). Severe Renal Impairment (CLer<30mL/min): Avoid use of lithium ( 2.5).

Before initiating treatment with lithium, renal function, vital signs, serum electrolytes, and thyroid function should be evaluated. Concurrent medications should be assessed, and if the patient is a woman of childbearing potential, pregnancy status and potential should be considered.

See Table 1 for dosage recommendations for acute and maintenance treatment of bipolar I disorder in adult and pediatric patients (7 to 17 years). Obtain serum lithium concentration assay after 3 days, drawn 12 hours after the last oral dose and regularly until patient is stabilized. Fine hand tremor, polyuria, and thirst may occur during initial therapy for the acute manic phase and may persist throughout treatment. Nausea and general discomfort may also appear during the first few days of lithium administration. These adverse reactions may subside with continued treatment, concomitant administration with food, or temporary reduction or cessation of dosage.

Blood samples for serum lithium determination should be drawn immediately prior to the next dose when lithium concentrations are relatively stable (i.e., 12 hours after the previous dose). Total reliance must not be placed on serum concentrations alone. Accurate patient evaluation requires both clinical and laboratory analysis. In addition to regular monitoring of serum lithium concentrations for patients on maintenance treatment, serum lithium concentrations should be monitored after any change in dosage, concurrent medication (e.g., diuretics, non-steroidal anti-inflammatory drugs, renin-angiotensin system antagonists, or metronidazole), marked increase or decrease in routinely performed strenuous physical activity (such as an exercise program) and in the event of a concomitant disease [see Boxed Warning, Warnings and Precautions ( 5.1), Drug Interactions ( 7.1)] . Patients abnormally sensitive to lithium may exhibit toxic signs at serum concentrations that are within what is considered the therapeutic range. Geriatric patients often respond to reduced dosage, and may exhibit signs of toxicity at serum concentrations ordinarily tolerated by other patients [see Specific Populations ( 8.5)] .

If the decision is made to continue lithium treatment during pregnancy, monitor serum lithium concentrations and adjust the dosage as needed in a pregnant woman because renal lithium clearance increases during pregnancy. Avoid sodium restriction or diuretic administration. To decrease the risk of postpartum lithium intoxication, decrease or discontinue lithium therapy two to three days before the expected delivery date to reduce neonatal concentrations and reduce the risk of maternal lithium intoxication due to the change in vascular volume which occurs during delivery. At delivery, vascular volume rapidly decreases and the renal clearance of lithium may decrease to pre-pregnancy concentrations. Restart treatment at the preconception dose when the patient is medically stable after delivery with careful monitoring of serum lithium concentrations [see Warnings and Precautions ( 5.1) and Use in Specific Populations ( 8.1)] .

Start patients with mild to moderately impaired renal function (creatinine clearance 30 to 89 mL/min evaluated by Cockcroft-Gault) with dosages less than those for patients with normal renal function [see Dosage and Administration ( 2.2)] . Titrate slowly while frequently monitoring serum lithium concentrations and monitoring for signs of lithium toxicity. Lithium is not recommended for use in patients with severe renal impairment (creatinine clearance less than 30 mL/min evaluated by Cockcroft-Gault) [see Use in Specific Populations ( 8.6)] .

Each 150 mg capsule for oral administration contains: lithium carbonate USP and is an opaque, white capsule, imprinted with product identification “54 213” on both the cap and the body and containing a white powder. Capsules: 150 mg of lithium carbonate ( 3)

Lithium is contraindicated in patients with known hypersensitivity to any inactive ingredient in the lithium carbonate tablet or capsule or lithium citrate products [see Adverse Reactions ( 6)]. Known hypersensitivity to any inactive ingredient in the drug product. ( 4)

Lithium-Induced Polyuria: May develop during initiation of treatment. Increases risk of lithium toxicity. Educate patient to avoid dehydration. Monitor for lithium toxicity and metabolic acidosis. Discontinue lithium or treat with amiloride as a therapeutic agent ( 5.2). Hyponatremia: Symptoms are more severe with faster-onset hyponatremia. Dehydration from protracted sweating, diarrhea, or elevated temperatures from infection increases risk of hyponatremia and lithium toxicity. Educate patients on maintaining a normal diet with salt and staying hydrated. Monitor for and treat hyponatremia and lithium toxicity, which may necessitate a temporary reduction or cessation of lithium and infusion of serum sodium ( 5.3). Lithium-Induced Chronic Kidney Disease: Associated with structural changes in patients on chronic lithium therapy. Monitor kidney function during treatment with lithium ( 5.4). Encephalopathic Syndrome: Increased risk in patients treated with lithium and an antipsychotic. Monitor routinely for changes to cognitive function ( 5.5). Hypothyroidism and Hyperthyroidism: Monitor thyroid function regularly ( 5.7). Hypercalcemia and Hyperparathyroidism: Associated with long-term lithium use. Monitor serum calcium ( 5.8).

The toxic concentrations for lithium (≥1.5 mEq/L) are close to the therapeutic range (0.8 to 1.2mEq/L). Some patients abnormally sensitive to lithium may exhibit toxic signs at serum concentrations that are considered within the therapeutic range [see Boxed Warning, Dosage and Administration ( 2.3)] . Lithium may take up to 24 hours to distribute into brain tissue, so occurrence of acute toxicity symptoms may be delayed. Neurological signs of lithium toxicity range from mild neurological adverse reactions such as fine tremor, lightheadedness, lack of coordination, and weakness; to moderate manifestations like giddiness, apathy, drowsiness, hyperreflexia, muscle twitching, ataxia, blurred vision, tinnitus, and slurred speech; and severe manifestations such as clonus, confusion, seizure, coma, and death. In rare cases, neurological sequelae may persist despite discontinuing lithium treatment and may be associated with cerebellar atrophy. Cardiac manifestations involve electrocardiographic changes, such as prolonged QT interval, ST and T-wave changes and myocarditis. Renal manifestations include urine concentrating defect, nephrogenic diabetes insipidus, and renal failure. Respiratory manifestations include dyspnea, aspiration pneumonia, and respiratory failure. Gastrointestinal manifestations include nausea, vomiting, diarrhea, and bloating. No specific antidote for lithium poisoning is known [see Overdosage ( 10)] . The risk of lithium toxicity is increased by: Recent onset of concurrent febrile illness Concomitant administration of drugs which increase lithium serum concentrations by pharmacokinetic interactions or drugs affecting kidney function [ see Drug Interactions (7)]. Acute ingestion Impaired renal function Volume depletion or dehydration Significant cardiovascular disease Changes in electrolyte concentrations (especially sodium and potassium) Monitor for signs and symptoms of lithium toxicity. If symptoms occur, decrease dosage or discontinue lithium treatment.

Chronic lithium treatment may be associated with diminution of renal concentrating ability, occasionally presenting as nephrogenic diabetes insipidus, with polyuria and polydipsia. The concentrating defect and natriuretic effect characteristic of this condition may develop within weeks of lithium initiation. Lithium can also cause renal tubular acidosis, resulting in hyperchloremic metabolic acidosis. Such patients should be carefully managed to avoid dehydration with resulting lithium retention and toxicity. This condition is usually reversible when lithium is discontinued, although for patients treated with long-term lithium, nephrogenic diabetes insipidus may be only partly reversible upon discontinuation of lithium. Amiloride may be considered as a therapeutic agent for lithium-induced nephrogenic diabetes insipidus.

Lithium can cause hyponatremia by decreasing sodium reabsorption by the renal tubules, leading to sodium depletion. Therefore, it is essential for patients receiving lithium treatment to maintain a normal diet, including salt, and an adequate fluid intake (2500 to 3000 mL) at least during the initial stabilization period. Decreased tolerance to lithium has also been reported to ensue from protracted sweating or diarrhea and, if such occur, supplemental fluid and salt should be administered under careful medical supervision and lithium intake reduced or suspended until the condition is resolved. In addition, concomitant infection with elevated temperatures may also necessitate a temporary reduction or cessation of medication. Symptoms are also more severe with faster-onset hyponatremia. Mild hyponatremia (i.e., serum Na > 120 mEq/L) can be asymptomatic. Below this threshold, clinical signs are usually present, consisting mainly of changes in mental status, such as altered personality, lethargy, and confusion. For more severe hyponatremia (serum Na < 115 mEq/L), stupor, neuromuscular hyperexcitability, hyperreflexia, seizures, coma, and death can result. During treatment of hyponatremia, serum sodium should not be elevated by more than 10 to 12 mEq/L in 24 hours, or 18 mEq/L in 48 hours. In the case of severe hyponatremia where severe neurologic symptoms are present, a faster infusion rate to correct serum sodium concentration may be needed. Patients rapidly treated or with serum sodium <120mEq/L are more at risk of developing osmotic demyelination syndrome (previously called central pontine myelinolysis). Occurrence is more common among patients with alcoholism, undernutrition, or other chronic debilitating illness. Common signs include flaccid paralysis, dysarthria. In severe cases with extended lesions patients may develop a locked-in syndrome (generalized motor paralysis). Damage often is permanent. If neurologic symptoms start to develop during treatment of hyponatremia, serum sodium correction should be suspended to mitigate the development of permanent neurologic damage.

The predominant form of chronic renal disease associated with long-term lithium treatment is a chronic tubulointerstitial nephropathy (CTIN). The biopsy findings in patients with lithium induced CTIN include tubular atrophy, interstitial fibrosis, sclerotic glomeruli, tubular dilation, and nephron atrophy with cyst formation. The relationship between renal function and morphologic changes and their association with lithium treatment has not been established. CTIN patients might present with nephrotic proteinuria (>3.0g/dL), worsening renal insufficiency and/or nephrogenic diabetes insipidus. Postmarketing cases consistent with nephrotic syndrome in patients with or without CTIN have also been reported. The biopsy findings in patients with nephrotic syndrome include minimal change disease and focal segmental glomerulosclerosis. The discontinuation of lithium in patients with nephrotic syndrome has resulted in remission of nephrotic syndrome. Kidney function should be assessed prior to and during lithium treatment. Routine urinalysis and other tests may be used to evaluate tubular function (e.g., urine specific gravity or osmolality following a period of water deprivation, or 24-hour urine volume) and glomerular function (e.g., serum creatinine, creatinine clearance, or proteinuria). During lithium treatment, progressive or sudden changes in renal function, even within the normal range, indicate the need for re-evaluation of treatment.

An encephalopathic syndrome, characterized by weakness, lethargy, fever, tremulousness and confusion, extrapyramidal symptoms, leukocytosis, elevated serum enzymes, BUN and fasting blood glucose, has occurred in patients treated with lithium and an antipsychotic. In some instances, the syndrome was followed by irreversible brain damage. Because of a possible causal relationship between these events and the concomitant administration of lithium and antipsychotics, patients receiving such combined treatment should be monitored closely for early evidence of neurological toxicity and treatment discontinued promptly if such signs appear. This encephalopathic syndrome may be similar to or the same as neuroleptic malignant syndrome (NMS).

Lithium can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, triptans, tricyclic antidepressants, fentanyl, tramadol, tryptophan, buspirone, and St. John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Drug Interactions ( 7.1)]. Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Monitor all patients taking lithium for the emergence of serotonin syndrome. Discontinue treatment with lithium and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of lithium with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

Lithium is concentrated within the thyroid and can inhibit thyroid synthesis and release which can lead to hypothyroidism. Where hypothyroidism exists, careful monitoring of thyroid function during lithium stabilization and maintenance allows for correction of changing thyroid parameters, if any. Where hypothyroidism occurs during lithium stabilization and maintenance, supplemental thyroid treatment may be used. Paradoxically, some cases of hyperthyroidism have been reported including Grave’s disease, toxic multinodular goiter and silent thyroiditis. Monitor thyroid function before the initiation of treatment, at three months and every six to twelve months while treatment is ongoing. If serum thyroid tests warrant concern, monitoring should occur more frequently.

Long-term lithium treatment is associated with persistent hyperparathyroidism and hypercalcemia. When clinical manifestations of hypercalcemia are present, lithium withdrawal and change to another mood stabilizer may be necessary. Hypercalcemia may not resolve upon discontinuation of lithium, and may require surgical intervention. Lithium-induced cases of hyperparathyroidism are more often multiglandular compared to standard cases. False hypercalcemia due to plasma volume depletion resulting from nephrogenic diabetes insipidus should be excluded in individuals with mildly increased serum calcium. Monitor serum calcium concentrations regularly.

There have been postmarketing reports of a possible association between treatment with lithium and the unmasking of Brugada Syndrome. Brugada Syndrome is a disorder characterized by abnormal electrocardiographic (ECG) findings and a risk of sudden death. Lithium should be avoided in patients with Brugada Syndrome or those suspected of having Brugada Syndrome. Consultation with a cardiologist is recommended if: (1) treatment with lithium is under consideration for patients suspected of having Brugada Syndrome or patients who have risk factors for Brugada Syndrome, e.g., unexplained syncope, a family history of Brugada Syndrome, or a family history of sudden unexplained death before the age of 45 years, (2) patients who develop unexplained syncope or palpitations after starting lithium treatment.

Cases of pseudotumor cerebri (increased intracranial pressure and papilledema) have been reported with lithium use. If undetected, this condition may result in enlargement of the blind spot, constriction of visual fields and eventual blindness due to optic atrophy. Consider discontinuing lithium if this syndrome occurs.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Pediatric Patients (7 to 17 years): Bipolar I Disorder: The following findings are based on an 8-week, placebo-controlled study for acute manic or mixed episodes of bipolar I disorder in pediatric patients 7 to 17 years (N= 81). In this study, lithium was administered at daily doses ranging from 300 to 3600 (mean dose 1483 mg ± 584) with serum levels ranging from 0 to 2.0 (mean level 0.98 mEq/L ± 0.47). Common Adverse Reactions (incidence ≥ 5% and at least twice the rate of placebo): nausea/vomiting, polyuria, thyroid abnormalities, tremor, thirst/polydipsia, dizziness, rash/dermatitis, ataxia/gait disturbance, decreased appetite, and blurry vision. Adverse Reactions Occurring at an Incidence of 2% or More in Lithium-Treated Pediatric Patients: Adverse reactions associated with the use of lithium (incidence of 2% or greater, rounded to the nearest percent, and lithium incidence greater than placebo) that occurred during acute therapy (up to 8-weeks in pediatric patients with bipolar disorder) are shown in Table 3.

Diuretics, NSAID, renin-angiotensin system antagonists, or metronidazole may increase lithium serum concentrations. Recommend frequent monitoring of serum lithium concentration and adjust dosage when necessary. ( 2.3, 7.1) Serotonergic Agents: Increased risk of serotonin syndrome when co-administered with lithium. ( 5.6, 7.1) Antipsychotics: There have been reports of neurologic adverse reactions in patients treated with lithium and an antipsychotic, ranging from extrapyramidal symptoms to neuroleptic malignant syndrome. ( 5.5, 7.1)

Pregnancy: May cause fetal and/or neonatal harm ( 8.1) Renal Impairment: Use caution during dose selection, starting with dosages less than those for patients with normal renal function while carefully monitoring for side effects ( 2.5, 6)

Risk Summary: Lithium may cause harm when administered to a pregnant woman. Early voluntary reports to international birth registries suggested an increase in cardiovascular malformations, especially for Ebstein’s anomaly, with first trimester use of lithium. Subsequent case-control and cohort studies indicate that the increased risk for cardiac malformations is likely to be small; however, the data are insufficient to establish a drug-associated risk. There are concerns for maternal and/or neonatal lithium toxicity during late pregnancy and the postpartum period [see Clinical Considerations]. Published animal developmental and toxicity studies in mice and rats report an increased incidence of fetal mortality, decreased fetal weight, increased fetal skeletal abnormalities, and cleft palate (mouse fetuses only) with oral doses of lithium that produced serum concentrations similar to the human therapeutic range. Other published animal studies report adverse effects on embryonic implantation in rats after lithium administration. Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population(s) is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations: Dose Adjustments During Pregnancy and the Postpartum Period: If the decision is made to continue lithium treatment during pregnancy, serum lithium concentrations should be monitored and the dosage adjusted during pregnancy. Two to three days prior to delivery, lithium dosage should be decreased or discontinued to reduce the risk of maternal and/or neonatal toxicity. Lithium may be restarted in the post-partum period at preconception doses in medically stable patients as long as serum lithium levels are closely monitored [see Dosage and Administration ( 2.4), Warnings and Precautions ( 5.1)] . Fetal/Neonatal Adverse Reactions: Lithium toxicity may occur in neonates who were exposed to lithium in late pregnancy. A floppy baby syndrome including neurological, cardiac, and hepatic abnormalities that are similar to those seen with lithium toxicity in adults have been observed. Symptoms include hypotonia, respiratory distress syndrome, cyanosis, lethargy, feeding difficulties, depressed neonatal reflexes, neonatal depression, apnea, and bradycardia. Monitor neonates and provide supportive care until lithium is excreted and toxic signs disappear, which may take up to 14 days. Consider fetal echocardiography between 16 and 20 weeks gestation in a woman with first trimester lithium exposure because of the potential increased risk of cardiac malformations.

Risk Summary: Limited published data reports the presence of lithium carbonate in human milk with breast milk levels measured at 0.12 to 0.7 mEq or 40 to 45% of maternal plasma levels. Infants exposed to lithium during breastfeeding may have plasma levels that are 30 to 40% of maternal plasma levels. Signs and symptoms of lithium toxicity such as hypertonia, hypothermia, cyanosis, and ECG changes have been reported in some breastfed neonates and infants. Increased prolactin levels have been measured in lactating women, but the effects on milk production are not known. Breastfeeding is not recommended with maternal lithium use; however, if a woman chooses to breastfeed, the infant should be closely monitored for signs of lithium toxicity. Discontinue breastfeeding if a breastfed infant develops lithium toxicity. Clinical Considerations: Consider regular monitoring of lithium levels and thyroid function in a breastfed infant.

The safety and effectiveness of lithium for monotherapy treatment of acute manic or mixed episodes of bipolar I disorder and maintenance monotherapy of bipolar I disorder in pediatric patients ages 7 to 17 years of age have been established in an acute-phase clinical trial of 8 weeks in duration followed by a 28-week randomized withdrawal phase [see Dosage and Administration ( 2.1), Adverse Reactions ( 6.1), Clinical Pharmacology ( 12.3), Clinical Studies ( 14)] . The safety and effectiveness of lithium has not been established in pediatric patients less than 7 years of age with bipolar I disorder.

Clinical studies of lithium carbonate tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other treatment. Lithium is known to be substantially excreted by the kidneys, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

As lithium is eliminated primarily through the kidney, lithium renal clearance is decreased in patients with abnormal renal function, and the risk of lithium intoxication increases considerably in this setting. Lithium should not be used in severe renal insufficiency (creatinine clearance less than 30 mL/min evaluated by Cockcroft-Gault), especially if the condition requires adherence to a low-sodium diet [see Dosage and Administration ( 2.5)] . Start patients with mild to moderately impaired renal function (creatinine clearance 30 to 89 mL/min evaluated by Cockcroft-Gault) with lower doses of lithium and titrate slowly while frequently monitoring serum lithium concentrations and for signs of lithium toxicity [see Dosage and Administration ( 2.5)].

The toxic concentrations for lithium (≥ 1.5 mEq/L) are close to the therapeutic concentrations [see Warnings and Precautions ( 5.1)] . At lithium concentrations greater than 3 mEq/L, patients may progress to seizures, coma, and irreversible brain damage. Treatment: For current information on the management of poisoning or overdosage, contact the National Poison Control Center at 1-800-222-1222 or www.poison.org. No specific antidote for lithium poisoning is known. Mild symptoms of lithium toxicity can usually be treated by reduction in dose or cessation of the drug. In severe cases of lithium poisoning, the goal of treatment is elimination of this ion from the patient. Administration of gastric lavage should be performed, but use of activated charcoal is not recommended as it does not significantly absorb lithium ions. Hemodialysis is the treatment of choice as it is an effective and rapid means of removing lithium in patients with severe toxicity. As an alternative option, urea, mannitol and aminophylline can induce a significant increase in lithium excretion. Appropriate supportive care for the patient should be undertaken. Patients with impaired consciousness should have their airway protected and it is critical to correct any volume depletion or electrolyte imbalance. Patients should be monitored to prevent hypernatremia while receiving normal saline and careful regulation of kidney function is of utmost importance. Serum lithium concentrations should be closely monitored as there may be a rebound in serum lithium concentrations as a result of delayed diffusion from the body tissues. Likewise, during the late recovery phase, lithium should be re-administered with caution taking into account the possible release of significant lithium stores in body tissues.

Each tablet for oral administration contains lithium carbonate USP, 300 mg and the following inactive ingredients: calcium stearate, microcrystalline cellulose, povidone, purified water, sodium lauryl sulfate, and sodium starch glycolate. Each capsule for oral administration contains lithium carbonate USP, 150 mg, 300 mg or 600 mg and the following inactive ingredient: talc. The capsule shells contain black monogramming ink, FD&C Red No. 40 (300 mg and 600 mg only), gelatin and titanium dioxide. The black monogramming ink contains ammonium hydroxide, ethanol, iron oxide black, isopropyl alcohol, N-butyl alcohol, propylene glycol and shellac glaze. Each 5 mL of solution for oral administration contains lithium ion (Li+), 8 mEq (equivalent to amount of lithium in 300 mg of lithium carbonate), alcohol 0.3% v/v and the following other inactive ingredients: citric acid, purified water, raspberry blend, sodium benzoate and sorbitol solution. Lithium Oral Solution is a palatable oral dosage form of lithium ion. It is prepared in solution from lithium hydroxide and citric acid in a ratio approximately di-lithium citrate. Lithium is an element of the alkali-metal group with atomic number 3, atomic weight 6.94, and an emission line at 671 nm on the flame photometer. The empirical formula for Lithium Citrate is C 6H 5Li 3O 7; molecular weight 209.93. Lithium acts as an antimanic. Lithium Carbonate USP is a granular, white powder with molecular formula Li 2CO 3 and molecular weight 73.89.

The mechanism of action of lithium as a mood stabilizing agent is unknown.

Absorption: After oral administration, lithium is reported to be completely absorbed in the upper gastrointestinal tract. Peak serum concentrations (T max) occur 0.25 to 3 hours after oral administration of immediate release preparations and 2 to 6 hours after sustained-release preparations. Distribution: The distribution space of lithium approximates that of total body water, and the plasma protein binding is negligible. After equilibrium, the apparent volume of distribution is 0.7 to 1 L/kg. Metabolism: Lithium is not metabolized. Excretion: Lithium is primarily excreted in urine, proportionally to its serum concentration. Lithium is filtered by the glomerulus, and 80% is reabsorbed by passive diffusion in the proximal tubule. The elimination half-life of lithium is approximately 18 to 36 hours. Lithium excretion in feces is insignificant. Specific Populations: Pediatric Use: A pharmacokinetic study of lithium was performed in 39 subjects with bipolar I disorder. Both apparent clearance and apparent volume of distribution increase as body weight increases. A lower dose in patients < 30 kg is necessary to achieve lithium exposures in pediatric patients similar to those observed in adults treated at recommended doses of lithium [see Dosage and Administration ( 2.2)] . The estimated plasma clearance was 0.59 L/h, 0.79 L/h and 1.17 L/h for pediatric patients weighing 20 kg, 30 kg and 50 kg, respectively.

Carcinogenesis: There have been no long-term studies performed in animals to evaluate the carcinogenic potential of lithium. Mutagenesis: There have been no adequate studies conducted to evaluate the mutagenic and genotoxic potential of lithium. Impairment of Fertility: There have been no adequate studies performed in animals at current standards to evaluate the effect of lithium treatment on fertility. However, published studies in male mice and rats administered repeated daily dosing of lithium carbonate report adverse effects on male reproductive organs, decreased spermatogenesis and decreased testosterone levels.

The safety and efficacy of lithium as a treatment for acute manic or mixed episodes of bipolar I disorder in pediatric patients (ages 7 to ≤18 years) was demonstrated in an 8-week, randomized, placebo-controlled, parallel group study (NCT01166425). In this study, 81 patients with a Young Mania Rating Scale (YMRS) score of 20 or more were randomized to receive lithium or placebo in a 2:1 ratio. Patients weighing more than 30 kg started lithium at 300 mg three times daily (900 mg/day) and could increase their dose by 300 mg every 3 days. Patients weighing 20 to 30 kg started lithium at 300 mg twice daily (600 mg/day) and could increase their dose by 300 mg weekly. No patients weighing less than 20 kg were enrolled. Lithium (mean serum level 0.98 ± 0.47 mEq/L) was statistically significantly superior to placebo in decreasing acute mania or mixed states as measured by the YMRS (see Table 5). In a 28-week randomized withdrawal analysis, 31 pediatric patients stabilized on lithium were assigned to either continue lithium or switch to placebo. The group receiving lithium demonstrated superiority to those receiving placebo in all-cause discontinuation (see Table 5). Table 5: Primary Efficacy Results
