Lurasidone interacts in the following cases:
Caution is advised when prescribing lurasidone with medicinal products known to prolong the QT interval, e.g. class IA antiarrhythmics (e.g. quinidine, disopyramide) and class III antiarrhythmics (e.g. amiodarone, sotalol), some antihistaminics, some other antipsychotics and some antimalarials (e.g. mefloquine).
Given the primary central nervous system effects of lurasidone, lurasidone should be used with caution in combination with other centrally acting medicinal products and alcohol.
Lurasidone is an in vitro inhibitor of the efflux transporter BCRP and the clinical relevance of intestinal BCRP inhibition cannot be excluded. Concomitant administration of BCRP substrates may result in increases in the plasma concentrations of these substrates.
Co-administration of lurasidone with midazolam, a sensitive CYP3A4 substrate, resulted in a <1.5-fold increase in midazolam exposure. Monitoring is recommended when lurasidone and CYP3A4 substrates known to have a narrow therapeutic index (e.g. astemizole, terfenadine, cisapride, pimozide, quinidine, bepridil or ergot alkaloids [ergotamine, dihydroergotamine]) are coadministered.
Lurasidone is a substrate of P-gp and BCRP in vitro and the in vivo relevance of this is unclear. Coadministration of lurasidone with P-gp and BCRP inhibitors may increase exposure to lurasidone.
Co-administration of lurasidone with digoxin (a P-gp substrate) did not increase the exposure to digoxin and only slightly increased Cmax (1.3–fold) and therefore, it is considered that lurasidone can be coadministered with digoxin. Lurasidone is an in vitro inhibitor of the efflux transporter P-gp and the clinical relevance of intestinal P-gp inhibition cannot be excluded. Concomitant administration of the P-gp substrate dabigatran etexilate may result in increased dabigatran plasma concentrations.
A starting dose of 18.5 mg is recommended and the maximum dose of lurasidone should not exceed 74 mg once daily in combination with moderate CYP3A4 inhibitors.
Co-administration of lurasidone with medicinal products that moderately inhibit CYP3A4 (e.g. diltiazem, erythromycin, fluconazole verapamil) may increase exposure to lurasidone. Moderate CYP3A4 inhibitors are estimated to result in a 2-5 fold increase in exposure of CYP3A4 substrates.
Co-administration of lurasidone with diltiazem (slow-release formulation), a moderate CYP3A4 inhibitor, resulted in a 2.2 and 2.4-fold increase in exposure of lurasidone and ID-14283 respectively. The use of an immediate release formulation of diltiazem could result in a larger increase in lurasidone exposure.
Co-administration of lurasidone with mild (e.g. armodafinil, amprenavir, aprepitant, prednisone, rufinamide) or moderate (e.g. bosentan, efavirenz, etravirine, modafinil, nafcillin) inducers of CYP3A4 would be expected to give a <2-fold reduction in lurasidone exposure during co-administration and for up to 2 weeks after discontinuation of mild or moderate CYP3A4 inducers.
When lurasidone is coadministered with mild or moderate CYP3A4 inducers, the efficacy of lurasidone needs to be carefully monitored and a dose adjustment may be needed.
In patients with moderate (Creatinine Clearance (CrCl) ≥30 and <50 ml/min), severe renal impairment (CrCL >15 and <30 ml/min) and End Stage Renal Disease (ESRD) patients (CrCl <15 ml/min), the recommended starting dose is 18.5 mg and the maximum dose should not exceed 74 mg once daily. Lurasidone should not be used in patients with ESRD unless the potential benefits outweigh the potential risks. If used in ESRD, clinical monitoring is advised.
Dose adjustment is recommended in moderate (Child-Pugh Class B) and severe hepatic impairment (Child-Pugh Class C) patients. The recommended starting dose is 18.5 mg. The maximum daily dose in moderate hepatic impairment patients should not exceed 74 mg and in severe hepatic impairment patients should not exceed 37 mg once daily.
Studies in animals have shown a number of effects on fertility, mainly related to prolactin increase, which are not considered to be relevant to human reproduction.
Co-administration of lurasidone with lithium indicated that lithium had clinically negligible effects on the pharmacokinetics of lurasidone, therefore no dose adjustment of lurasidone is required when coadministered with lithium. Lurasidone does not impact concentrations of lithium.
Medicinal products with dopamine receptor antagonistic properties have been associated with the induction of tardive dyskinesia characterised by rhythmical involuntary movements, predominantly of the tongue and/or face. If signs and symptoms of tardive dyskinesia appear, the discontinuation of all antipsychotics, including lurasidone, should be considered.
Neuroleptic Malignant Syndrome, characterised by hyperthermia, muscle rigidity, autonomic instability, altered consciousness and elevated serum creatine phosphokinase levels, has been reported to occur with lurasidone. Additional signs may include myoglobinuria (rhabdomyolysis) and acute renal failure. In this event, lurasidone should be discontinued.
Lurasidone elevates prolactin levels due to antagonism of dopamine D2 receptors. Patients should be counseled on signs and symptoms of elevated prolactin, such as gynecomastia, galactorrhea, amenorrhea and erectile dysfunction. Patient should be advised to seek medical attention if they experience any signs and symptoms.
Lurasidone may cause orthostatic hypotension, perhaps due to its α1-adrenergic receptor antagonism. Monitoring of orthostatic vital signs should be considered in patients who are vulnerable to hypotension.
Cases of venous thromboembolism (VTE) have been reported with antipsychotic medicinal products. Since patients treated with antipsychotics often present with acquired risk factors for VTE, all possible risk factors for VTE should be identified before and during treatment with lurasidone and preventive measures undertaken.
Medicinal products with dopamine receptor antagonistic properties have been associated with extrapyramidal adverse reactions including rigidity, tremors, mask-like face, dystonias, drooling of saliva, drooped posture and abnormal gait. In placebo controlled clinical studies in adult patients with schizophrenia there was an increased occurrence of EPS following treatment with lurasidone compared to placebo.
If prescribed to patients with Parkinson’s disease, antipsychotic medicinal products may exacerbate the underlying parkinsonism symptoms. Physicians should therefore weigh the risks versus the benefits when prescribing lurasidone to patients with Parkinson’s disease.
Rare cases of glucose related adverse reactions, e.g. increase in blood glucose, have been reported in clinical trials with lurasidone. Appropriate clinical monitoring is advisable in diabetic patients and in patients with risk factors for the development of diabetes mellitus.
Weight gain has been observed with atypical antipsychotic use. Clinical monitoring of weight is recommended.
Lurasidone should be used cautiously in patients with a history of seizures or other conditions that potentially lower the seizure threshold.
There are no or limited amount of data (less than 300 pregnancy outcomes) from the use of lurasidone in pregnant women. Animal studies are insufficient with respect to effects on pregnancy, embryonal/foetal development, parturition and postnatal development. The potential risk for humans is unknown. Lurasidone should not be used during pregnancy unless clearly necessary.
Neonates exposed to antipsychotics (including lurasidone) during the third trimester are at risk of adverse reactions including extrapyramidal and/or withdrawal symptoms that may vary in severity and duration following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, or feeding disorder. Consequently, newborns should be monitored carefully.
Lurasidone was excreted in milk of rats during lactation. It is not known whether lurasidone or its metabolites are excreted in human milk. Breast feeding in women receiving lurasidone should be considered only if the potential benefit of treatment justifies the potential risk to the child.
Studies in animals have shown a number of effects on fertility, mainly related to prolactin increase, which are not considered to be relevant to human reproduction.
Lurasidone has minor influence on the ability to drive and use machines. Patients should be cautioned about operating hazardous machines, including motor vehicles and cycles, until they are reasonably certain that lurasidone does not affect them adversely. Regarding road safety, adolescents who may not be old enough to drive may nevertheless cycle.
The safety of lurasidone has been evaluated at doses of 18.5-148 mg in clinical studies in patients with schizophrenia treated for up to 52 weeks and in the post-marketing setting. The most common adverse drug reactions (ADRs) (≥10%) were akathisia and somnolence, which were dose-related up to 111 mg daily.

Post marketing reports of clinically serious cases of skin and other hypersensitivity reactions have been reported in association with lurasidone treatment, including some reports of StevensJohnson syndrome.
In the adult short-term placebo-controlled studies, the incidence of reported events related to EPS, excluding akathisia and restlessness, was 13.5% for lurasidone-treated subjects versus 5.8% for placebo-treated subjects. The incidence of akathisia for lurasidone-treated subjects was 12.9% versus 3.0% for placebo-treated subjects. In the adolescent short-term placebo-controlled study, the incidence of reported events related to EPS, excluding akathisia, was 5.1% for lurasidone-treated subjects versus 1.8% for placebo-treated subjects. The incidence of akathisia for lurasidone-treated subjects was 8.9% versus 1.8% for placebo-treated subjects.
Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, difficulty swallowing, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity, higher potency and at higher doses of first generation antipsychotic medicinal products. An elevated risk of acute dystonia is observed in males and younger age groups.
Cases of venous thromboembolism, including cases of pulmonary embolism and cases of deep vein thrombosis have been reported with antipsychotic drugs-Frequency unknown.
