Lurasidone (Latuda) Dosing for Bipolar Depression
For adults with bipolar depression, the recommended starting dose of Latuda (lurasidone) is 20 mg once daily, with an effective dose range of 20-120 mg daily taken with food (at least 350 calories). 1
Dosing Guidelines for Adults
- Starting dose: 20 mg once daily
- Effective dose range: 20-120 mg once daily
- Maximum recommended dose: 120 mg daily
- Administration: Must be taken with food (at least 350 calories) to substantially increase absorption (increases AUC approximately 2-fold and Cmax approximately 3-fold) 1
- Titration: Initial dose titration is not required, but dose may be adjusted based on clinical response
- Important note: Higher dose range (80-120 mg/day) did not provide additional efficacy on average compared to lower dose range (20-60 mg/day) in monotherapy studies 1
Dosing Guidelines for Pediatric Patients (10-17 years)
- Starting dose: 20 mg once daily
- Effective dose range: 20-80 mg once daily
- Maximum recommended dose: 80 mg daily
- Titration: Dose may be increased after one week based on clinical response
- Clinical practice note: Most pediatric patients (67%) received 20 mg or 40 mg once daily in clinical studies 1
Dose Modifications
Renal Impairment
- Moderate impairment (CrCl 30-50 mL/min): Start at 20 mg/day, maximum 80 mg/day
- Severe impairment (CrCl <30 mL/min): Start at 20 mg/day, maximum 80 mg/day 1
Hepatic Impairment
- Moderate impairment (Child-Pugh Score 7-9): Start at 20 mg/day, maximum 80 mg/day
- Severe impairment (Child-Pugh Score 10-15): Start at 20 mg/day, maximum 40 mg/day 1
Drug Interactions
- Strong CYP3A4 inhibitors: Contraindicated (e.g., ketoconazole, clarithromycin, ritonavir)
- Moderate CYP3A4 inhibitors: Reduce dose to half of original dose (maximum 80 mg/day) 1
Efficacy and Safety Profile
Lurasidone has demonstrated efficacy for bipolar depression as both monotherapy and adjunctive therapy with lithium or valproate 2, 3
Common side effects include:
- Akathisia (most common)
- Somnolence
- Extrapyramidal symptoms
- Nausea and gastrointestinal upset 2
Advantages over other antipsychotics:
Duration of Treatment
- The effectiveness of lurasidone for longer-term use (beyond 6 weeks) has not been established in controlled studies
- Physicians should periodically re-evaluate the long-term usefulness of the drug for individual patients 1
- Long-term treatment (28 weeks) has shown continued improvement in depressive symptoms with good tolerability 5
Clinical Pearls and Pitfalls
- Critical requirement: Must be taken with food (at least 350 calories) for proper absorption
- Common pitfall: Failure to recognize that higher doses (80-120 mg) may not provide additional efficacy over lower doses (20-60 mg) for most patients
- Safety advantage: Minimal impact on weight and metabolic parameters makes lurasidone a good option for patients with metabolic concerns
- Monitoring: Regular assessment of extrapyramidal symptoms, particularly akathisia, is important
Lurasidone represents a valuable treatment option for bipolar depression with a favorable metabolic profile compared to many other antipsychotics, making it particularly suitable for patients with metabolic concerns or those who cannot tolerate weight gain associated with other medications.
