Common side effects include increased urination, shakiness of the hands, and increased thirst.[5] Serious side effects include hypothyroidism, diabetes insipidus, and lithium toxicity.[5] Blood level monitoring is recommended to decrease the risk of potential toxicity.[5] If levels become too high, diarrhea, vomiting, poor coordination, sleepiness, and ringing in the ears may occur.[5] Lithium is teratogenic and can cause birth defects at high doses, especially during the first trimester of pregnancy. The use of lithium while breastfeeding is controversial; however, many international health authorities advise against it, and the long-term outcomes of perinatal lithium exposure have not been studied.[6] The American Academy of Pediatrics lists lithium as contraindicated for pregnancy and lactation.[7] The United States Food and Drug Administration categorizes lithium as having positive evidence of risk for pregnancy and possible hazardous risk for lactation.[7][8]
Lithium salts are classified as mood stabilizers.[5] Lithium's mechanism of action is not known.[5]
In the nineteenth century, lithium was used in people who had gout, epilepsy, and cancer.[9] Its use in the treatment of mental disorders began with Carl Lange in Denmark[10] and William Alexander Hammond in New York City,[11] who used lithium to treat mania from the 1870s onwards, based on now-discredited theories involving its effect on uric acid. Use of lithium for mental disorders was re-established (on a different theoretical basis) in 1948 by John Cade in Australia.[9]Lithium carbonate is on the World Health Organization's List of Essential Medicines,[12] and is available as a generic medication.[5] In 2022, it was the 212th most commonly prescribed medication in the United States, with more than 1million prescriptions.[13][14] It appears to be underused in older people,[15] and in certain countries, for reasons including patients’ negative beliefs about lithium.[16]
Medical uses
In 1970, lithium was approved by the United States Food and Drug Administration (FDA) for the treatment of bipolar disorder, which remains its primary use in the US.[5][17] It is sometimes used when other treatments are not effective in a number of other conditions, including major depression,[18]schizophrenia, disorders of impulse control, and some psychiatric disorders in children.[5] Because the FDA has not approved lithium for the treatment of other disorders, such use is off-label.[19][18]
Bipolar disorder
Lithium is primarily used as a maintenance drug in the treatment of bipolar disorder to stabilize mood and prevent manic episodes, but it may also be helpful in the acute treatment of manic episodes.[20] Although recommended by treatment guidelines for the treatment of depression in bipolar disorder, the evidence that lithium is superior to placebo for acute depression is low-quality;[21][22]atypical antipsychotics are considered more effective for treating acute depressive episodes.[23]Lithium carbonate treatment was previously considered to be unsuitable for children; however, more recent studies show its effectiveness for treatment of early-onset bipolar disorder in children as young as eight. The required dosage is slightly less than the toxic level (representing a low therapeutic index), requiring close monitoring of blood levels of lithium carbonate during treatment.[24] Within the therapeutic range there is a dose-response relationship.[25] A limited amount of evidence suggests lithium carbonate may contribute to the treatment of substance use disorders for some people with bipolar disorder.[26][27][28] Although it is believed that lithium prevents suicide in people with bipolar disorder, a 2022 systematic review found that "Evidence from randomised trials is inconclusive and does not support the idea that lithium prevents suicide or suicidal behaviour."[29]
Schizophrenic disorders
Lithium is recommended for the treatment of schizophrenic disorders only after other antipsychotics have failed; it has limited effectiveness when used alone.[5] The results of different clinical studies of the efficacy of combining lithium with antipsychotic therapy for treating schizophrenic disorders have varied.[5]
Major depressive disorder
Lithium is widely prescribed as an adjunct treatment for depression.[19]
Augmentation
If therapy with antidepressants (such as selective serotonin reuptake inhibitors [SSRIs]) does not fully treat and discontinue[30] the symptoms of major depressive disorder (MDD) (also known as refractory depression or treatment resistant depression [TRD])[31] then a second augmentation agent is sometimes added to the therapy.[32] Lithium is one of the few augmentation agents for antidepressants to demonstrate efficacy in treating MDD in multiple randomized controlled trials and it has been prescribed (off-label) for this purpose since the 1980s.[18] A 2019 systematic review found some evidence of the clinical utility of adjunctive lithium, but the majority of supportive evidence is dated.[33]
While SSRIs have been mentioned above as a drug class in which lithium is used to augment, there are other classes in which lithium is added to increase effectiveness. Such classes are antipsychotics (used for bipolar disorder) as well as antiepileptic drugs (used for both psychiatric and epileptic cases). Lamotrigine and topiramate are two specific antiepileptic drugs in which lithium is used to augment.[34]
Monotherapy
There are a few old studies indicating efficacy of lithium for acute depression with lithium having the same efficacy as tricyclic antidepressants.[35] A recent study concluded that lithium works best on chronic and recurrent depression when compared to modern antidepressant (i.e. citalopram) but not for patients with no history of depression.[36] A 2019 systemic review found no evidence to support the use of lithium for monotherapy.[33]
Prevention of suicide
Lithium is widely believed to prevent suicide and is often used in clinical practice towards that end. However, meta-analyses, faced with evidence base limitations, have yielded differing results, and it therefore remains unclear whether or not lithium is efficacious in the prevention of suicide.[37][38][39][40][41][42] However, some evidence suggets it is effective in significantly reducing the risk of self-harm and unintentional injury for bipolar disorder in comparison to no treatment and to anti-psychotics or valporate.[43][44]
Alzheimer's disease
Alzheimer's disease affects forty-five million people and is the fifth leading cause of death in the 65-plus population.[45][failed verification] There is no complete cure for the disease, currently. However, lithium is being evaluated for its effectiveness as a potential therapeutic measure. One of the leading causes of Alzheimer's is the hyperphosphorylation of the tau protein by the enzyme GSK-3, which leads to the overproduction of amyloid peptides that cause cell death.[45] To combat this toxic amyloid aggregation, lithium upregulates the production of neuroprotectors and neurotrophic factors, as well as inhibiting the GSK-3 enzyme.[46] Lithium also stimulates neurogenesis within the hippocampus, making it thicker.[46] Yet another cause of Alzheimer's disease is the dysregulation of calcium ions within the brain.[47] Too much or too little calcium within the brain can lead to cell death.[47] Lithium can restore intracellular calcium homeostasis by inhibiting the wrongful influx of calcium upstream.[47] It also promotes the redirection of the influx of calcium ions into the lumen of the endoplasmic reticulum of the cells to reduce the oxidative stress within the mitochondria.[47]
In 2009, a study was performed by Hampel and colleagues[48] that asked patients with Alzheimer's to take a low dose of lithium daily for three months; it resulted in a significant slowing of cognitive decline, benefitting patients being in the prodromal stage the most.[46] Upon a secondary analysis, the brains of the Alzheimer's patients were studied and shown to have an increase in BDNF markers, meaning they had actually shown cognitive improvement.[46] Another study, a population study this time by Kessing et al.,[49] showed a negative correlation between Alzheimer's disease deaths and the presence of lithium in drinking water.[46] Areas with increased lithium in their drinking water showed less dementia overall in their population.[46]
Monitoring
Those who use lithium should receive regular serum level tests and should monitor thyroid and kidney function for abnormalities, as it interferes with the regulation of sodium and water levels in the body, and can cause dehydration. Dehydration, which is compounded by heat, can result in increasing lithium levels. The dehydration is due to lithium inhibition of the action of antidiuretic hormone, which normally enables the kidney to reabsorb water from urine. This causes an inability to concentrate urine, leading to consequent loss of body water and thirst.[50]
Lithium concentrations in whole blood, plasma, serum, or urine may be measured using instrumental techniques as a guide to therapy, to confirm the diagnosis in potential poisoning victims, or to assist in the forensic investigation in a case of fatal overdosage. Serum lithium concentrations are usually in the range of 0.5–1.3 mmol/L (0.5–1.3 mEq/L) in well-controlled people, but may increase to 1.8–2.5 mmol/L in those who accumulate the drug over time and to 3–10 mmol/L in acute overdose.[51][52]
Lithium salts have a narrow therapeutic/toxic ratio, so should not be prescribed unless facilities for monitoring plasma concentrations are available. Doses are adjusted to achieve plasma concentrations of 0.4[a][b] to 1.2 mmol/L[53] on samples taken 12 hours after the preceding dose.
Given the rates of thyroid dysfunction, thyroid parameters should be checked before lithium is instituted and monitored after 3–6 months and then every 6–12 months.[54]
Given the risks of kidney malfunction, serum creatinine, and eGFR should be checked before lithium is instituted and monitored after 3–6 months at regular intervals. Patients who have a rise in creatinine on three or more occasions, even if their eGFR is > 60 ml/min/
1.73m2 require further evaluation, including a urinalysis for haematuria, and proteinuria, a review of their medical history with attention paid to cardiovascular, urological, and medication history, and blood pressure control and management. Overt proteinuria should be further quantified with a urine protein-to-creatinine ratio.[55]
Discontinuation
For patients who have achieved long-term remission, it is recommended to discontinue lithium gradually and in a controlled fashion.[56][35]
Discontinuation symptoms may occur in patients stopping the medication including irritability, restlessness, and somatic symptoms like vertigo, dizziness, or lightheadedness. Symptoms occur within the first week and are generally mild and self-limiting within weeks.[57]
Hand tremor (usually transient, but can persist in some) with an incidence of 27%. If severe, psychiatrist may lower lithium dosage, change lithium salt type or modify lithium preparation from long to short-acting (despite lacking evidence for these procedures) or use pharmacological help[65]
Lithium carbonate can induce a 1–2 kg of weight gain.[69]
In addition to tremors, lithium treatment appears to be a risk factor for development of parkinsonism-like symptoms, although the causal mechanism remains unknown.[70]
Most side effects of lithium are dose-dependent. The lowest effective dose is used to limit the risk of side effects.
Hypothyroidism
The rate of hypothyroidism is around six times higher in people who take lithium. Low thyroid hormone levels in turn increase the likelihood of developing depression. People taking lithium thus should routinely be assessed for hypothyroidism and treated with synthetic thyroxine if necessary.[69]
Because lithium competes with the antidiuretic hormone in the kidney, it increases water output into the urine, a condition called nephrogenic diabetes insipidus. Clearance of lithium by the kidneys is usually successful with certain diuretic medications, including amiloride and triamterene.[71] It increases the appetite and thirst ("polydypsia") and reduces the activity of thyroid hormone (hypothyroidism).[72][73] The latter can be corrected by treatment with thyroxine and does not require the lithium dose to be adjusted. Lithium is also believed to cause renal dysfunction, although this does not appear to be common.[74]
Lambert et al. (2016), comparing the rate of hypothyroidism in patients with bipolar disorder treated with 9 different medications, found that lithium users do not have a particularly high rate of hypothyroidism (8.8%) among BD patients – only 1.39 times the rate in oxcarbazepine users (6.3%). Lithium and quetiapine are not statistically different in terms of hypothyroidism rates. However, lithium users are tested much more frequently for hypothyroidism than those using other drugs. The authors write that there may be an element of surveillance bias in understanding lithium's effects on the thyroid glands, as lithium users are tested 2.3–3.1 times as often. Furthermore, the authors argue that because hypothyroidism is common among BD patients regardless of lithium treatment, regular thyroid testing should be applied to all BD patients, not just those on lithium.[75][67]
Pregnancy
Lithium is a teratogen, which can cause birth defects in a small number of newborns. Case reports and several retrospective studies have demonstrated possible increases in the rate of a congenital heart defects including Ebstein's anomaly if taken during pregnancy. Teratogenicity is affected by trimester and dose of Lithium. Most significantly affecting first-trimester cardiac development with greater effects at higher doses. [76][77][78]
As the risks of stopping Lithium can be significant, patients are sometimes recommended to stay on this medicine while pregnant. Careful weighing of the risks and benefits should be made in consultation with a psychiatric physician. [79]
For patients who are exposed to lithium, or plan to stay on the medication throughout their pregnancy, fetal echocardiography is routinely performed to monitor for cardiac anomalies.[80]
While only small amounts of Lithium are transmitted to the infant in breastmilk, there is limited data on the safety of Breastfeeding while on Lithium. Medical evaluation and monitoring of infants consuming breastmilk during maternal prescription may be indicated.[81][82][83]
Kidney damage
Lithium has been associated with several forms of kidney injury.[84][85] It is estimated that impaired urinary concentrating ability is present in at least half of individuals on chronic lithium therapy, a condition called lithium-induced nephrogenic diabetes insipidus.[85] Continued use of lithium can lead to more serious kidney damage in an aggravated form of diabetes insipidus.[86][87] In rare cases, some forms of lithium-caused kidney damage may be progressive and lead to end-stage kidney failure with a reported incidence of 0.2% to 0.7%.[88]
Some reports of kidney damage may be wrongly attributed to lithium, increasing the apparent rate of this adverse effect.[66] Nielsen et al. (2018), citing 6 large observational studies since 2010, argue that findings of decreased kidney function are partially inflated by surveillance bias. Furthermore, modern data does not show that lithium increases the risk of end-stage kidney disease.[67] Davis et al. (2018), using literature from a wider timespan (1977–2018), also found that lithium's association with chronic kidney disease is unproven with various contradicting results. They also find contradicting results regarding end-stage kidney disease.[89]
A 2015 nationwide study suggests that chronic kidney disease can be avoided by maintaining the serum lithium concentration at a level of 0.6–0.8 mmol/L and by monitoring serum creatinine every 3–6 months.[67]
Lithium is primarily cleared from the body through glomerular filtration, but some is then reabsorbed together with sodium through the proximal tubule. Its levels are therefore sensitive to water and electrolyte balance.[91] Diuretics act by lowering water and sodium levels; this causes more reabsorption of lithium in the proximal tubules so that the removal of lithium from the body is less, leading to increased blood levels of lithium.[91][92] ACE inhibitors have also been shown in a retrospective case-control study to increase lithium concentrations. This is likely due to constriction of the afferent arteriole of the glomerulus, resulting in decreased glomerular filtration rate and clearance. Another possible mechanism is that ACE inhibitors can lead to a decrease in sodium and water. This will increase lithium reabsorption and its concentrations in the body.[91]
Some drugs can increase the clearance of lithium from the body, which can result in decreased lithium levels in the blood. These drugs include theophylline, caffeine, and acetazolamide. Additionally, increasing dietary sodium intake may also reduce lithium levels by prompting the kidneys to excrete more lithium.[93]
Lithium toxicity, which is also called lithium overdose and lithium poisoning, is the condition of having too much lithium in the blood. This condition also happens in persons who are taking lithium in which the lithium levels are affected by drug interactions in the body.
In acute toxicity, people have primarily gastrointestinal symptoms such as vomiting and diarrhea, which may result in volume depletion. During acute toxicity, lithium distributes later into the central nervous system resulting in mild neurological symptoms, such as dizziness.[54]
In chronic toxicity, people have primarily neurological symptoms which include nystagmus, tremor, hyperreflexia, ataxia, and change in mental status. During chronic toxicity, the gastrointestinal symptoms seen in acute toxicity are less prominent. The symptoms are often vague and nonspecific.[100]
If the lithium toxicity is mild or moderate, lithium dosage is reduced or stopped entirely. If the toxicity is severe, lithium may need to be removed from the body.
Mechanism of action
The specific biochemical mechanism of lithium action in stabilizing mood is unknown.[5]
Unlike many other psychoactive drugs, Li+ typically produces no obvious psychotropic effects (such as euphoria) in normal individuals at therapeutic concentrations.[101]
Lithium may also increase the release of serotonin by neurons in the brain.[102] In vitro studies performed on serotonergic neurons from rat raphe nuclei have shown that when these neurons are treated with lithium, serotonin release is enhanced during a depolarization compared to no lithium treatment and the same depolarization.[103]
Lithium both directly and indirectly inhibits GSK3β (glycogen synthase kinase 3β) which results in the activation of mTOR. This leads to an increase in neuroprotective mechanisms by facilitating the Akt signaling pathway.[104] GSK-3β is a downstream target of monoamine systems. As such, it is directly implicated in cognition and mood regulation.[105][104] During mania, GSK-3β is activated via dopamine overactivity.[104] GSK-3β inhibits the transcription factors β-catenin and cyclic AMP (cAMP) response element binding protein (CREB), by phosphorylation. This results in a decrease in the transcription of important genes encoding for neurotrophins.[106][107][108] In addition, several authors proposed that pAp-phosphatase could be one of the therapeutic targets of lithium.[109][110] This hypothesis was supported by the low Ki of lithium for human pAp-phosphatase compatible within the range of therapeutic concentrations of lithium in the plasma of people (0.8–1 mM). The Ki of human pAp-phosphatase is ten times lower than that of GSK3β (glycogen synthase kinase 3β). Inhibition of pAp-phosphatase by lithium leads to increased levels of pAp (3′-5′ phosphoadenosine phosphate), which was shown to inhibit PARP-1.[111]
Another mechanism proposed in 2007 is that lithium may interact with nitric oxide (NO) signaling pathway in the central nervous system, which plays a crucial role in neural plasticity. The NO system could be involved in the antidepressant effect of lithium in the Porsolt forced swimming test in mice.[112][113] It was also reported that NMDA receptor blockage augments antidepressant-like effects of lithium in the mouse forced swimming test,[114] indicating the possible involvement of NMDA receptor/NO signaling in the action of lithium in this animal model of learned helplessness.
Although the search for a novel lithium-specific receptor is ongoing, the high concentration of lithium compounds required to elicit a significant pharmacological effect leads mainstream researchers to believe that the existence of such a receptor is unlikely.[116]
During mania, there is an increase in neurotransmission of dopamine that causes a secondary homeostatic down-regulation, resulting in decreased neurotransmission of dopamine, which can cause depression.[115] Additionally, the post-synaptic actions of dopamine are mediated through G-protein coupled receptors. Once dopamine is coupled to the G-protein receptors, it stimulates other secondary messenger systems that modulate neurotransmission. Studies found that in autopsies (which do not necessarily reflect living people), people with bipolar disorder had increased G-protein coupling compared to people without bipolar disorder.[115] Lithium treatment alters the function of certain subunits of the dopamine-associated G-protein, which may be part of its mechanism of action.[115]
Glutamate and NMDA receptors
Glutamate levels are observed to be elevated during mania. Lithium is thought to provide long-term mood stabilization and have anti-manic properties by modulating glutamate levels.[115] It is proposed that lithium competes with magnesium for binding to NMDA glutamate receptor, increasing the availability of glutamate in post-synapticneurons, leading to a homeostatic increase in glutamate re-uptake which reduces glutamatergic transmission.[115]
The NMDA receptor is also affected by other neurotransmitters such as serotonin and dopamine. Effects observed appear exclusive to lithium and have not been observed by other monovalent ions such as rubidium and cesium.[115]
GABA receptors
GABA is an inhibitory neurotransmitter that plays an important role in regulating dopamine and glutamateneurotransmission.[115] It was found that patients with bipolar disorder had lower GABA levels, which results in excitotoxicity and can cause apoptosis (cell loss). Lithium has been shown to increase the level of GABA in plasma and cerebral spinal fluid.[117] Lithium counteracts these degrading processes by decreasing pro-apoptotic proteins and stimulating release of neuroprotective proteins.[115] Lithium's regulation of both excitatory dopaminergic and glutamatergic systems through GABA may play a role in its mood-stabilizing effects.[118]
Cyclic AMP secondary messengers
Lithium's therapeutic effects are thought to be partially attributable to its interactions with several signal transduction mechanisms.[119] The cyclic AMP secondary messenger system is shown to be modulated by lithium. Lithium was found to increase the basal levels of cyclic AMP but impair receptor-coupled stimulation of cyclic AMP production.[115] It is hypothesized that the dual effects of lithium are due to the inhibition of G-proteins that mediate cyclic AMP production.[115] Over a long period of lithium treatment, cyclic AMP and adenylate cyclase levels are further changed by gene transcription factors.[115]
Inositol depletion hypothesis
Lithium treatment has been found to inhibit the enzyme inositol monophosphatase, involved in degrading inositol monophosphate to inositol required in PIP2 synthesis. This leads to lower levels of inositol triphosphate, created by decomposition of PIP2.[120] This effect has been suggested to be further enhanced with an inositol triphosphate reuptake inhibitor. Inositol disruptions have been linked to memory impairment and depression. It is known with good certainty that signals from the receptors coupled to the phosphoinositidesignal transduction are affected by lithium.[121]myo-inositol is also regulated by the high affinity sodium mI transport system (SMIT). Lithium is hypothesized to inhibit mI entering the cells and mitigate the function of SMIT.[115] Reductions of cellular levels of myo-inositol results in the inhibition of the phosphoinositide cycle.[115]
Neurotrophic factors
Lithium's actions on Gsk3 result in activation of CREB, leading to higher expression of BDNF. (Valproate, another mood stabilizer, also increases the expression of BDNF.) As expected of increased BDNF expression, chronic lithium treatment leads to increased grey matter volume in brain areas implicated in emotional processing and cognitive control.[122] Bipolar patients treated with lithium also have higher white matter integrity compared to those taking other drugs.[123]
Lithium was first used in the 19th century as a treatment for gout after scientists discovered that, at least in the laboratory, lithium could dissolve uric acid crystals isolated from the kidneys. The levels of lithium needed to dissolve urate in the body, however, were toxic.[125] Because of prevalent theories linking excess uric acid to a range of disorders, including depressive and manic disorders, Carl Lange in Denmark[10] and William Alexander Hammond in New York City[11] used lithium to treat mania from the 1870s onwards.
By the turn of the 20th century, as theory regarding mood disorders evolved and so-called "brain gout" disappeared as a medical entity, the use of lithium in psychiatry was largely abandoned; however, several lithium preparations were still produced for the control of renal calculi and uric acid diathesis.[19] As accumulating knowledge indicated a role for excess sodium intake in hypertension and heart disease, lithium salts were prescribed to patients for use as a replacement for dietary table salt (sodium chloride). This practice and the sale of lithium itself were both banned in the United States in February 1949, following the publication of reports detailing side effects and deaths.[126]
Also in 1949, the Australian psychiatrist John Cade and Australian biochemistShirley Andrews rediscovered the usefulness of lithium salts in treating mania while working at the Royal Park Psychiatric Hospital in Victoria.[127] They were injecting rodents with urine extracts taken from manic patients in an attempt to isolate a metabolic compound which might be causing mental symptoms. Since uric acid in gout was known to be psychoactive, (adenosine receptors on neurons are stimulated by it; caffeine blocks them), they needed soluble urate for a control. They used lithium urate, already known to be the most soluble urate compound, and observed that it caused the rodents to become tranquil. Cade and Andrews traced the effect to the lithium-ion itself, and after Cade ingested lithium himself to ensure its safety in humans, he proposed lithium salts as tranquilizers. He soon succeeded in controlling mania in chronically hospitalized patients with them. This was one of the first successful applications of a drug to treat mental illness, and it opened the door for the development of medicines for other mental problems in the next decades.[128]
The rest of the world was slow to adopt this treatment, largely because of deaths that resulted from even relatively minor overdosing, including those reported from the use of lithium chloride as a substitute for table salt. Largely through the research and other efforts of Denmark's Mogens Schou and Paul Baastrup in Europe,[125] and Samuel Gershon and Baron Shopsin in the U.S., this resistance was slowly overcome. Following the recommendation of the APA Lithium Task Force (William Bunney, Irvin Cohen (Chair), Jonathan Cole, Ronald R. Fieve, Samuel Gershon, Robert Prien, and Joseph Tupin[129]), the application of lithium in manic illness was approved by the United States Food and Drug Administration in 1970,[130] becoming the 50th nation to do so.[19]
As with cocaine in Coca-Cola, lithium was widely marketed as one of several patent medicine products popular in the late 19th and early 20th centuries and was the medicinal ingredient of a refreshment beverage. Charles Leiper Grigg, who launched his St. Louis-based company The Howdy Corporation, invented a formula for a lemon-lime soft drink in 1920. The product, originally named "Bib-Label Lithiated Lemon-Lime Soda", was launched two weeks before the Wall Street Crash of 1929.[132] It contained the mood stabilizerlithium citrate, and was one of many patent medicine products popular in the late-19th and early-20th centuries.[133] Its name was soon changed to 7 Up. All American beverage makers were forced to remove lithium from beverages in 1948. Despite the ban, in 1950, the Painesville Telegraph still carried an advertisement for a lithiated lemon beverage.[134]
Tentative evidence in Alzheimer's disease showed that lithium may slow progression.[137][138] It has been studied for its potential use in the treatment of amyotrophic lateral sclerosis (ALS), but a study showed lithium had no effect on ALS outcomes.[139]
