Latuda Dosing Guidelines

Schizophrenia

For adults with schizophrenia, start Latuda at 40 mg once daily with food (at least 350 calories), with an effective dose range of 40-160 mg/day and maximum dose of 160 mg/day; no initial titration is required. 1

  • Adolescents (13-17 years): Start at 40 mg once daily, effective range 40-80 mg/day, maximum 80 mg/day 1
  • Administration with food is mandatory—it increases absorption approximately 2-fold (AUC) and 3-fold (Cmax) 1

Bipolar I Depression

For adults with bipolar I depression, start Latuda at 20 mg once daily (whether as monotherapy or adjunctive to lithium/valproate), with an effective range of 20-120 mg/day and maximum dose of 120 mg/day; notably, higher doses (80-120 mg/day) did not provide additional efficacy compared to lower doses (20-60 mg/day) in monotherapy studies. 1

The optimal therapeutic dose based on recent meta-analysis is 40-60 mg daily (specifically 50 mg showed SMD -0.60 for depression improvement), balancing efficacy with side effect profile 2. This dose range demonstrates:

  • Superior depression reduction (SMD -0.60)
  • Improved anxiety (SMD -0.32)
  • Better clinical global impression (SMD -0.67)
  • Reduced disability (SMD -0.38)

Pediatric patients (10-17 years): Start at 20 mg once daily, may increase after one week based on response, effective range 20-80 mg/day, maximum 80 mg/day. In clinical studies, 67% of patients received 20-40 mg/day at study end 1

Hepatic Impairment Dosing

For moderate hepatic impairment (Child-Pugh B, score 7-9), start at 20 mg/day with a maximum dose of 80 mg/day. 1

For severe hepatic impairment (Child-Pugh C, score 10-15), start at 20 mg/day with a maximum dose of 40 mg/day. 1

These dose reductions are necessary because patients with moderate to severe hepatic impairment have higher lurasidone exposure, increasing the risk of adverse reactions 1

Renal Impairment Dosing

For moderate renal impairment (CrCl 30 to <50 mL/min) or severe renal impairment (CrCl <30 mL/min), start at 20 mg/day with a maximum dose of 80 mg/day. 1

Drug Interaction Adjustments

  • Contraindicated: Do not use with strong CYP3A4 inhibitors (ketoconazole, clarithromycin, ritonavir, voriconazole) 1
  • Moderate CYP3A4 inhibitors: Dose adjustment required (specific guidance in full prescribing information) 1

Critical Administration Points

  • Always administer with food (minimum 350 calories) to ensure adequate absorption 1
  • No initial dose titration required for standard adult dosing in schizophrenia or bipolar depression 1
  • For bipolar depression specifically, the 20-60 mg/day range appears optimal based on efficacy data, as the 80-120 mg/day range showed no additional benefit 1, 2

Special Population Considerations

  • Elderly: No specific dose adjustment required based on age alone, though 20 mg/day showed similar concentrations to younger patients 1
  • Asian patients: Expert consensus supports 20 mg/day starting dose with titration up to 120 mg/day for adults, 20-80 mg/day for elderly 3
  • No adjustment needed for sex, race, or smoking status 1
