- Second Generation (Atypical) Antipsychotic
Iloperidone is a piperidinyl-benzisoxazole atypical antipsychotic with mixed D2/5-HT2 antagonist activity. It exhibits high affinity for 5-HT2A, NEα1, D2, and D3 receptors, low to moderate affinity for D1, D4, H1, 5-HT1A, 5-HT6, and 5-HT7 receptors, and no affinity for muscarinic receptors. The addition of serotonin antagonism to dopamine antagonism (classic neuroleptic mechanism) is thought to improve negative symptoms of psychoses and reduce the incidence of extrapyramidal side effects (Huttunen 1995). Iloperidone’s low affinity for histamine H1 receptors may decrease the risk for weight gain and somnolence while its affinity for NE α1/α2C may improve cognitive function but increase the risk for orthostasis (Arif 2011, Huttunen 1995, Nasrallah 2008).

Concerns related to adverse effects:
• Altered cardiac conduction: May alter cardiac conduction and prolong the QTc interval; life-threatening arrhythmias have occurred with therapeutic doses of antipsychotics. Risks may be increased by conditions or concomitant medications which cause bradycardia, hypokalemia, and/or hypomagnesemia. Avoid use in combination with QTc-prolonging drugs. Avoid use in patients with congenital long QT syndrome, history of cardiac arrhythmia, recent MI, and/or uncompensated heart failure. Use caution in combination with drugs that inhibit iloperidone metabolism. Discontinue in patients found to have persistent QTc intervals >500 msec. Patients with symptoms of dizziness, palpitations, or syncope should receive further cardiac evaluation.
• Blood dyscrasias: Leukopenia, neutropenia, and agranulocytosis (sometimes fatal) have been reported in clinical trials and postmarketing reports with antipsychotic use; presence of risk factors (eg, pre-existing low WBC or history of drug-induced leuko-/neutropenia) should prompt periodic blood count assessment. Discontinue therapy at first signs of blood dyscrasias or if absolute neutrophil count <1,000/mm3.
• Cerebrovascular effects: An increased incidence of cerebrovascular effects (eg, transient ischemic attack, stroke), including fatalities, has been reported in placebo-controlled trials of antipsychotics for the unapproved use in elderly patients with dementia-related psychosis.
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery or driving).
• Dyslipidemia: Undesirable alterations in lipids has been reported with atypical antipsychotics. Use with caution in patients with a pre-existing abnormal lipid profile.
• Esophageal dysmotility/aspiration: Antipsychotic use has been associated with esophageal dysmotility and aspiration; use with caution in patients at risk of aspiration pneumonia (eg, Alzheimer disease).
• Extrapyramidal symptoms (EPS): May cause EPS, including pseudoparkinsonism, acute dystonic reactions, akathisia, and tardive dyskinesia (risk of these reactions is generally much lower relative to typical/conventional antipsychotics). Risk of dystonia (and probably other EPS) may be greater with increased doses, use of conventional antipsychotics, males, and younger patients. Risk of tardive dyskinesia and potential for irreversibility may be increased in elderly patients (particularly women), prolonged therapy, and higher total cumulative dose; antipsychotics may also mask signs/symptoms of tardive dyskinesia. Consider therapy discontinuation with signs/symptoms of tardive dyskinesia.
• Hyperglycemia: Atypical antipsychotics have been associated with development of hyperglycemia; in some cases, may be extreme and associated with ketoacidosis, hyperosmolar coma, or death. Use with caution in patients with diabetes or other disorders of glucose regulation; monitor for worsening of glucose control.
• Hyperprolactinemia: Use is associated with increased prolactin levels; clinical significance of hyperprolactinemia in patients with breast cancer or other prolactin-dependent tumors is unknown.
• Hypersensitivity: Hypersensitivity reactions, including anaphylaxis, angioedema, throat tightness, oropharyngeal swelling, swelling of the face, lips, mouth and tongue, rash, pruritus, and urticaria, have been reported.
• Neuroleptic malignant syndrome (NMS): Use may be associated with NMS; monitor for mental status changes, fever, muscle rigidity and/or autonomic instability; risk may be increased in patients with Parkinson disease or Lewy body dementia. (McKeith 2002)
• Orthostatic hypotension: May cause orthostatic hypotension associated with dizziness, tachycardia, and syncope; use with caution in patients with known cardiovascular disease (heart failure, history of myocardial infarction or ischemia, conduction abnormalities), cerebrovascular disease, or conditions that predispose the patient to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications).
• Priapism: Rare cases of priapism have been reported.
• Suicidal ideation: The possibility of a suicide attempt is inherent in psychotic illness; use with caution in high-risk patients during initiation of therapy. Prescribe the smallest quantity consistent with good patient care.
• Temperature regulation: Impaired core body temperature regulation may occur; caution with strenuous exercise, heat exposure, dehydration, and concomitant medication possessing anticholinergic effects.
• Weight gain: Significant weight gain has been observed with antipsychotic therapy; incidence varies with product. Monitor waist circumference and BMI.
• Dementia: [US Boxed Warning]: Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Most deaths appeared to be either cardiovascular (eg, heart failure, sudden death) or infectious (eg, pneumonia) in nature. Iloperidone is not approved for the treatment of dementia-related psychosis.
• Hepatic impairment: Use is not recommended in patients with severe hepatic impairment; use caution and consider dosage reduction in patients with moderate hepatic impairment.
• Seizures: Use with caution in patients at risk of seizures, including those with a history of seizures, head trauma, brain damage, alcoholism, or concurrent therapy with medications which may lower seizure threshold. Elderly patients may be at increased risk of seizures due to an increased prevalence of predisposing factors.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• CYP2D6 poor metabolizers: Use with caution in patients known to be poor metabolizers of CYP2D6; dosage adjustment recommended.
• Elderly: Use caution in older adults due to increased sensitivity to adverse effects (eg, tardive dyskinesia and seizures).
Mental status; vital signs (as clinically indicated); blood pressure (baseline; repeat 3 months after antipsychotic initiation, then yearly); ECG (as clinically indicated); weight, height, BMI, waist circumference (baseline; repeat at 4, 8, and 12 weeks after initiating or changing therapy, then quarterly; consider switching to a different antipsychotic for a weight gain ≥5% of initial weight); CBC (as clinically indicated; monitor frequently during the first few months of therapy in patients with preexisting low WBC or history of drug-induced leukopenia/neutropenia); electrolytes (annually and as clinically indicated; perform baseline serum potassium and magnesium with periodic monitoring in patients at risk for significant electrolyte disturbances); liver function (annually and as clinically indicated); personal and family history of obesity, diabetes, dyslipidemia, hypertension, or cardiovascular disease (baseline; repeat annually); fasting plasma glucose level/HbA1c (baseline; repeat 3 months after starting antipsychotic, then yearly); fasting lipid panel (baseline; repeat 3 months after initiation of antipsychotic; if LDL level is normal, repeat at 2- to 5-year intervals or more frequently if clinical indicated); changes in menstruation, libido, development of galactorrhea, erectile and ejaculatory function (at each visit for the first 12 weeks after the antipsychotic is initiated or until the dose is stable, then yearly); abnormal involuntary movements or parkinsonian signs (baseline; repeat weekly until dose stabilized for at least 2 weeks after introduction and for 2 weeks after any significant dose increase); tardive dyskinesia (every 12 months; high-risk patients every 6 months); ocular examination (yearly in patients >40 years; every 2 years in younger patients) (ADA, 2004; Lehman, 2004; Marder, 2004).
Adverse events have been observed in animal reproduction studies. Antipsychotic use during the third trimester of pregnancy has a risk for abnormal muscle movements (extrapyramidal symptoms [EPS]) and/or withdrawal symptoms in newborns following delivery. Symptoms in the newborn may include agitation, feeding disorder, hypertonia, hypotonia, respiratory distress, somnolence, and tremor; these effects may be self-limiting or require hospitalization. Iloperidone may cause hyperprolactinemia, which may decrease reproductive function in both males and females.
The ACOG recommends that therapy during pregnancy be individualized; treatment with psychiatric medications during pregnancy should incorporate the clinical expertise of the mental health clinician, obstetrician, primary healthcare provider, and pediatrician. Safety data related to atypical antipsychotics during pregnancy is limited and routine use is not recommended. However, if a woman is inadvertently exposed to an atypical antipsychotic while pregnant, continuing therapy may be preferable to switching to a typical antipsychotic that the fetus has not yet been exposed to; consider risk:benefit (ACOG, 2008).
Healthcare providers are encouraged to enroll women 18 to 45 years of age exposed to iloperidone during pregnancy in the Atypical Antipsychotics Pregnancy Registry (1-866-961-2388 or http://www.womensmentalhealth.org/pregnancyregistry).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, weight gain, dry mouth, fatigue, loss of strength and energy, rhinitis, or diarrhea. Have patient report immediately to prescriber signs of infection, signs of neuroleptic malignant syndrome (fever, muscle cramps or stiffness, dizziness, very bad headache, confusion, change in thinking, fast heartbeat, abnormal heartbeat, or sweating a lot), signs of high blood sugar (confusion, feeling sleepy, more thirst, hunger, passing urine more often, flushing, fast breathing, or breath that smells like fruit), suicidal ideation, tachycardia, arrhythmia, severe dizziness, passing out, behavioral changes, mood changes, tremors, difficulty moving, rigidity, urinary retention, change in amount of urine passed, dysphagia, seizures, shortness of breath, enlarged breasts, sexual dysfunction, nipple discharge, amenorrhea, priapism, or signs of tardive dyskinesia (unable to control body movements; tongue, face, mouth, or jaw sticking out; mouth puckering; and puffing cheeks) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
