The recommended starting dose of LATUDA ((LURASIDONE HCL) is 40 mg once daily. LATUDA has been shown to be effective in a dose range of 40 mg/day to 120 mg/day. In the 6-week controlled trials, there was no suggestion of added benefit with the 120 mg/day dose, but there was a dose -related increase in certain adverse reactions. Therefore, the maximum recommended dose is 80 mg/day

[35S]GTPγS binding experiments for the human dopamine D2L or 5-HT1A receptors stably expressed in the membranes of recombinant Chinese hamster ovary (CHO) cells were performed. After dopamine (or serotonin) and/or lurasidone were incubated for 20 min at room temperature with the cell membrane preparation containing [35S]GTPγS (0.05 nM for D2L or 0.2 nM for 5-HT1A), the membranes were filtered through glass filters and the radioactivity bound to each filter was measured with a liquid scintillation counter. For nonspecific binding, cold GTPγS (20 μM for D2L or 10 μM for 5-HT1A) was added with [35S]GTPγS. in vitro receptor binding experiments revealed that lurasidone demonstrates affinity for dopamine D2 and 5-HT2A receptors higher than other tested antipsychotics. In contrast to other agents, lurasidone also displayed high affinity for 5-HT7, 5-HT1A, and noradrenaline α2C receptors.
