Lurasidonedosage

Lurasidone hydrochloride tablets should be taken with food (at least 350 calories). Administration with food substantially increases the absorption of lurasidone hydrochloride tablets. Indication Starting Dose Recommended Dose Schizophrenia – adults 40 mg per day 40 mg to 160 mg per day Schizophrenia – adolescents (13 to 17 years) 40 mg per day 40 mg to 80 mg per day Bipolar Depression - adults 20 mg per day 20 mg to 120 mg per day Bipolar Depression – pediatric patients (10 to 17 years) 20 mg per day 20 mg to 80 mg per day

Moderate and Severe Renal Impairment: Recommended starting dose is 20 mg per day, and the maximum recommended dose is 80 mg per day.

Moderate and Severe Hepatic Impairment: Recommended starting dose is 20 mg per day. The maximum recommended dose is 80 mg per day in moderate hepatic impairment and 40 mg per day in severe hepatic impairment.

Concomitant Use of a Moderate CYP3A4 inhibitor (e.g., diltiazem): Lurasidone hydrochloride tablets dose should be reduced to half of the original dose level. Recommended starting dose is 20 mg per day. Maximum recommended dose is 80 mg per day.

Concomitant Use of a Moderate CYP3A4 Inducer: It may be necessary to increase the dose of lurasidone hydrochloride tablets.

2.1 Schizophrenia

Adults The recommended starting dose of lurasidone hydrochloride tablets is 40 mg once daily. Initial dose titration is not required. Lurasidone hydrochloride tablets have been shown to be effective in a dose range of 40 mg per day to 160 mg per day. The maximum recommended dose is 160 mg per day. Adolescents (13 to 17 years) The recommended starting dose of lurasidone hydrochloride tablets is 40 mg once daily. Initial dose titration is not required. Lurasidone hydrochloride tablets have been shown to be effective in a dose range of 40 mg per day to 80 mg per day. The maximum recommended dose is 80 mg per day.

2.2 Depressive

Episodes Associated with Bipolar I Disorder Adults The recommended starting dose of lurasidone hydrochloride tablets is 20 mg given once daily as monotherapy or as adjunctive therapy with lithium or valproate. Initial dose titration is not required. Lurasidone hydrochloride tablets have 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). Pediatric Patients (10 to 17 years) The recommended starting dose of lurasidone hydrochloride tablets are 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. Lurasidone hydrochloride tablets have 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. The efficacy of lurasidone hydrochloride tablets in the treatment of mania associated with bipolar disorder has not been established.

2.3 Administration

Information Lurasidone hydrochloride tablets should be taken with food (at least 350 calories). Administration with food substantially increases the absorption of lurasidone hydrochloride tablets. Administration with food increases the AUC approximately 2-fold and increases the C max approximately 3-fold. In the clinical studies, lurasidone hydrochloride tablets was administered with food. The effectiveness of lurasidone hydrochloride tablets for longer-term use, that is, for more than 6 weeks, has not been established in controlled studies. Therefore, the physician who elects to use lurasidone hydrochloride tablets for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient.

2.4 Dose Modifications for

Renal Impairment Dose adjustment is recommended in moderate (creatinine clearance: 30 to <50 mL/min) and severe renal impairment (creatinine clearance <30 mL/min) patients. The recommended starting dose is 20 mg per day. The dose in these patients should not exceed 80 mg per day.

2.5 Dose Modifications for

Hepatic Impairment Dose adjustment is recommended in moderate (Child-Pugh Score = 7 to 9) and severe hepatic impairment (Child-Pugh Score = 10 to 15) patients. The recommended starting dose is 20 mg per day. The dose in moderate hepatic impairment patients should not exceed 80 mg per day and the dose in severe hepatic impairment patients should not exceed 40 per mg/day.

2.6 Dose Modifications

Due to Drug Interactions of CYP3A4 Inhibitors and CYP3A4 Inducers Concomitant Use with CYP3A4 Inhibitors Lurasidone hydrochloride tablets should not be used concomitantly with a strong CYP3A4 inhibitor (e.g., ketoconazole, clarithromycin, ritonavir, voriconazole, mibefradil, etc.). If lurasidone hydrochloride tablets are being prescribed and a moderate CYP3A4 inhibitor (e.g. diltiazem, atazanavir, erythromycin, fluconazole, verapamil etc.) is added to the therapy, the lurasidone hydrochloride tablets dose should be reduced to half of the original dose level. Similarly, if a moderate CYP3A4 inhibitor is being prescribed and lurasidone hydrochloride tablets are added to the therapy, the recommended starting dose of lurasidone hydrochloride tablets are 20 mg per day, and the maximum recommended dose of lurasidone hydrochloride tablets are 80 mg per day. Grapefruit and grapefruit juice should be avoided in patients taking lurasidone hydrochloride tablets, since these may inhibit CYP3A4 and alter lurasidone hydrochloride tablets concentrations. Concomitant Use with CYP3A4 Inducers Lurasidone hydrochloride tablets should not be used concomitantly with a strong CYP3A4 inducer (e.g., rifampin, avasimibe, St. John’s wort, phenytoin, carbamazepine, etc.). If lurasidone hydrochloride tablets are used concomitantly with a moderate CYP3A4 inducer, it may be necessary to increase the lurasidone hydrochloride tablets dose after chronic treatment (7 days or more) with the CYP3A4 inducer.
