Adult dose and duration20 mg once daily to start, taken with food. US label verbatim: "The recommended starting dose of LATUDA is 20 mg given once daily as monotherapy or as adjunctive therapy with lithium or valproate. Initial dose titration is not required. LATUDA has been shown to be effective in a dose range of 20 mg per day to 120 mg per day as monotherapy or as adjunctive therapy with lithium or valproate. The maximum recommended dose, as monotherapy or as adjunctive therapy with lithium or valproate, is 120 mg per day. In the monotherapy study, the higher dose range (80 mg to 120 mg per day) did not provide additional efficacy, on average, compared to the lower dose range (20 to 60 mg per day)". Food is part of the dose, not a comfort measure: "LATUDA should be taken with food (at least 350 calories). Administration with food substantially increases the absorption of LATUDA." Kidney and liver cut the ceiling - in moderate or severe renal impairment and in moderate or severe hepatic impairment the label starts at 20 mg and caps at 80 mg per day. - Long enough to see the depressive episode through, then re-judged. US label verbatim: "The effectiveness of LATUDA for longer-term use, that is, for more than 6 weeks, has not been established in controlled studies." The label goes on to ask that anyone using it for extended periods re-evaluate its long-term usefulness for that individual patient at intervals.
Paediatric doseAge restriction: minimum 120 months
(Licensed from 10 years for bipolar depression, monotherapy only. US label verbatim: "The recommended starting dose of LATUDA is 20 mg given once daily as monotherapy. Initial dose titration is not required. The dose may be increased after one week based on clinical response. LATUDA has been shown to be effective in a dose range of 20 mg per day to 80 mg per day as monotherapy. At the end of the clinical study, most of the patients (67%) received 20 mg or 40 mg once daily. The maximum recommended dose is 80 mg per day.")

Dose sourceLATUDA (lurasidone hydrochloride) tablets US prescribing information, boxed warning, section 1 Indications and Usage and section 2 Dosage and Administration (DailyMed SetID afad3051-9df2-4c54-9684-e8262a133af8)
WhyThe disease article names it first-line for the depressive phase, verbatim: "For patients not already taking long-term medication for BD, first-line monotherapy includes quetiapine, olanzapine, or lurasidone (has not been studied in acute bipolar mania)." and again in combination - "Combination treatment with olanzapine-fluoxetine, lithium plus lamotrigine, and lurasidone plus lithium or valproate may also be considered." The US label's indication section names the same phase of the same disease, verbatim: "Monotherapy treatment of adult and pediatric patients (10 to 17 years) with major depressive episode associated with bipolar I disorder (bipolar depression)" and "Adjunctive treatment with lithium or valproate in adult patients with major depressive episode associated with bipolar I disorder (bipolar depression)". The dose comes from the US label because the European SmPC for the same drug is written for schizophrenia alone and carries no bipolar regimen. Nine lurasidone products are on the Egyptian register, from ELBALURAN 20 mg at 165 EGP upward, and it matters in a country where valproate is barred for women of childbearing potential.
Cautions- RED FLAG - boxed warning, suicidal thoughts and behaviours. US label verbatim: "Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adults in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors." Bipolar depression is the phase in which most suicide deaths happen, so this is not a background risk.
- RED FLAG - boxed warning, elderly patients with dementia. US label verbatim: "Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. LATUDA is not approved for the treatment of patients with dementia-related psychosis."
- Not a drug for mania. The US label says there is no established efficacy for lurasidone in bipolar mania, and StatPearls agrees in its own terms: no trial evidence supports its use in an acute manic episode. A patient swinging into mania needs a different drug on the card.
- Taken on an empty stomach it may not work. The label ties absorption to a meal of at least 350 calories, and states that food increases the area under the curve roughly two-fold. A patient who takes it at bedtime hours after eating is not getting the studied exposure.
- Valproate, one of the alternatives beside it, carries a hard bar in one group. It must not be given to a woman of childbearing potential: the fetal risk - teratogenesis, and impaired intellectual development - is unacceptable.
- A depressive episode with psychosis or active suicidal intent is a same-day psychiatric problem, not a prescription problem. Where a patient with bipolar disorder presents in acute depression, the disease article puts the risk of suicide and self-harm ahead of everything else in management.
