Lurasidone (Latuda)

Antipsychoticprescriptionoral · inferred

Benzisothiazol atypical antipsychotic with high affinity for D2, 5-HT2A, and 5-HT7 receptors and moderate alpha-2c antagonism. Uniquely low affinity for H1 and 5-HT2C receptors, resulting in minimal weight gain and metabolic effects compared to other atypicals. Must be taken with food (≥350 calories) — bioavailability doubles with food. Metabolized by CYP3A4; contraindicated with strong 3A4 inhibitors/inducers.

Lurasidone (Latuda) modeled serum levels with a loading dose of 65.0 mg, then 40 mg once daily The first dose is larger so levels approach steady state faster. 0 2.5 5 7.5 10 Day 0 Day 4 Day 8 Day 11 Day 15 Time on a regular schedule

Maintenance schedule: 40 mg once daily (oral).

Loading schedule: 65.0 mg on day 1, then 40 mg once daily — reaching therapeutic levels sooner.

Modeled steady state after ~2 days: peak ≈ 5.5 mg, trough ≈ 2.3 mg body load. Population-based estimate over 15 days for a 40 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
