RISPERDAL CONSTA Product Profile


Excellent clinical efficacy

In clinical trials, RISPERDAL CONSTA demonstrated significant improvement in patients with schizophrenia as measured on the Positive and Negative Syndrome Scale (PANSS). PANSS is a composite scale designed to assess severity of psychopathology in adult patients. The scale emphasizes positive and negative symptom dimensions.

  • Pivotal study demonstrates significant symptomatic improvement1
    • 400 patients with schizophrenia participated in a 12-week, double-blind clinical trial
    • RISPERDAL CONSTA demonstrated significant improvement vs placebo
    • Improvement was seen in both inpatients as well as outpatients
    • Published in The American Journal of Psychiatry, June 2003

Innovative delivery system

  • RISPERDAL CONSTA is the first and only long-acting, water-based atypical injection
  • Only minimal pain was reported by patients on first injection, and that diminished with subsequent injections

RISPERDAL CONSTA provides established safety and tolerability

  • The overall incidence of EPS-related adverse events in patients treated with 25 mg and 50 mg of RISPERDAL CONSTA and placebo, respectively,
    were* :
    — Akathisia (2%, 9%, 4%)
    — Parkinsonism, ie, bradykinesia, extrapyramidal
       disorder, hypokinesia (4%, 10%, 3%)
    — Tremor (0%, 3%, 0%)
  • Incidence of discontinuation due to adverse events with RISPERDAL CONSTA vs placebo: 11% vs 13%*
  • Minimal weight gain*
    — 1.1-lb mean change in the 25-mg group and 2.6 lb in the 50-mg group

    Commonly observed events: Treatment-emergent adverse events with an incidence of 5% or greater in at least one of the RISPERDAL CONSTA groups (25 mg or 50 mg) and at least twice that of placebo were: somnolence, akathisia, parkinsonism, dyspepsia, constipation, dry mouth, fatigue, and weight increase.

Confidence of assured coverage

  • Professionally administered dose every two weeks
  • Can help guide treatment decisions by providing knowledge of therapeutic coverage
  • A long-acting, professionally administered injectable medication, while not guaranteeing medication adherence, allows you to recognize and intervene when a patient misses a dose.

Start the switch to RISPERDAL CONSTA

If patient has never received risperidone, rule out the possibility of hypersensitivity reaction prior to treatment with RISPERDAL CONSTA.

Starting treatment regardless of prior or current antipsychotic therapy:
  • 25 mg once every two weeks by IM gluteal injection
  • Antipsychotic supplementation is needed during the first three weeks of therapy with RISPERDAL CONSTA

Important Safety Information

Commonly observed events: Treatment-emergent adverse events with an incidence of 5% or greater in at least one of the RISPERDAL CONSTA groups (25 mg or 50 mg) and at least twice that of placebo were: somnolence, akathisia, parkinsonism, dyspepsia, constipation, dry mouth, fatigue and weight increase.

Maintenance treatment: Patients should be periodically reassessed to determine the need for continued treatment.

Weight gain: In a 12 week trial, percentage of patients experiencing weight gain (≥7% of baseline body weight) was 6% placebo vs 9% RISPERDAL CONSTA.

Hyperglycemia & diabetes mellitus: Hyperglycemia, some cases extreme and associated with ketoacidosis, hyperosmolar coma or death has been reported in patients treated with atypical antipsychotics (APS), including RISPERDAL CONSTA. Patients starting treatment with APS who have or are at risk for diabetes, should undergo fasting blood glucose testing at the beginning of and during treatment. Patients who develop symptoms of hyperglycemia should also undergo fasting blood glucose testing.

Orthostatic hypotension: Orthostatic hypotension was reported (<2%) in clinical trials.

Tardive dyskinesia: As with all antipsychotic medications, prescribing should be consistent with the need to minimize the risk of tardive dyskinesia; if its signs and symptoms appear, discontinuation of RISPERDAL CONSTA should be considered. In the integrated database of multiple-dose studies the incidence of tardive dyskinesia was 0.6% (9/1499 patients).

Extrapyramidal symptoms: The overall incidence of EPS-related adverse events in patients treated with 25 mg & 50 mg of RISPERDAL CONSTA and placebo respectively, were akathisia (2%, 9%, 4%), parkinsonism* (4%, 10%, 3%) and tremor (0%, 3%, 0%). *Bradykinesia, extrapyramidal disorder, and hypokinesia.

Additional considerations for special populations: Limited clinical trial data are available in elderly, renally or hepatically impaired patients, and RISPERDAL CONSTA should be used cautiously in these patients.

Cerebrovascular adverse events (CAEs): Cerebrovascular adverse events (CAEs), including fatalities, have been reported in elderly patients with dementia-related psychosis taking oral risperidone in clinical trials. The incidence of CAEs with oral risperidone was significantly higher than with placebo. RISPERDAL CONSTA is not approved for treating these patients.

NMS:  Neuroleptic malignant syndrome (NMS) has been reported rarely with this class of medications, including RISPERDAL CONSTA and appropriate management should be employed.

Hyperprolactinemia:  As with other drugs that antagonize dopamine D2 receptors, risperidone elevates prolactin levels and the elevation persists during chronic administration.

IMPORTANT SAFETY INFORMATION FOR RISPERDAL® CONSTA®


Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with atypical antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in the drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. RISPERDAL® CONSTA® (risperidone) is not approved for the treatment of patients with dementia-related psychosis.

Cerebrovascular Adverse Events (CAEs): CAEs, including fatalities, have been reported in elderly patients with dementia-related psychosis taking oral risperidone in clinical trials. The incidence of CAEs with risperidone was significantly higher than with placebo. RISPERDAL® CONSTA® is not approved for the treatment of patients with dementia-related psychosis.

Neuroleptic Malignant Syndrome (NMS): NMS, a potentially fatal symptom complex, has been reported with the use of antipsychotic medications, including RISPERDAL® CONSTA®. Clinical manifestations include muscle rigidity, fever, altered mental status and evidence of autonomic instability (see full Prescribing Information). Management should include immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, intensive symptomatic treatment and medical monitoring, and treatment of any concomitant serious medical problems.

Tardive Dyskinesia (TD): TD is a syndrome of potentially irreversible, involuntary, dyskinetic movements that may develop in patients treated with antipsychotic medications. The risk of developing TD and the likelihood that dyskinetic movements will become irreversible are believed to increase with duration of treatment and total cumulative dose. Elderly patients appeared to be at increased risk for TD. Prescribing should be consistent with the need to minimize the risk of TD. The syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn.

Hyperglycemia and Diabetes: Hyperglycemia, some cases extreme and associated with ketoacidosis, hyperosmolar coma or death has been reported in patients treated with atypical antipsychotics (APS), including RISPERDAL® CONSTA®. Patients starting treatment with APS who have or are at risk for diabetes should undergo fasting blood glucose testing at the beginning of and during treatment. Patients who develop symptoms of hyperglycemia should also undergo fasting blood glucose testing.

Hyperprolactinemia: As with other drugs that antagonize dopamine D2 receptors, RISPERDAL® CONSTA® elevates prolactin levels and the elevation persists during chronic administration. Risperidone is associated with higher levels of prolactin elevation than other antipsychotic agents.

Orthostatic Hypotension: RISPERDAL® CONSTA® may induce orthostatic hypotension associated with dizziness, tachycardia, and in some patients, syncope, especially during the initial dose-titration period. Monitoring should be considered in patients for whom this may be of concern.
RISPERDAL® CONSTA® should be used with caution in patients with known cardiovascular disease, and conditions that would predispose patients to hypotension.

Potential for Cognitive and Motor Impairment: RISPERDAL® CONSTA® has the potential to impair judgment, thinking, or motor skills. Patients should be cautioned about operating hazardous machinery, including motor vehicles, until they are reasonably certain that RISPERDAL® CONSTA® does not affect them adversely.

Seizures: RISPERDAL® CONSTA® should be used cautiously in patients with a history of seizures.

Suicide: The possibility of suicide attempt is inherent in psychotic illnesses. Close supervision of high-risk patients should accompany drug therapy.

Symptoms (EPS): The overall incidence of EPS-related adverse events in patients treated with 25 mg and 50 mg of RISPERDAL® CONSTA® and placebo, respectively, were akathisia* (4%, 11%, 6%), Parkinsonism** (8%, 15%, 9%) and tremor (0%, 3%, 0%).
* Akathisia and restlessness
** Extrapyramidal disorder, musculoskeletal stiffness, muscle rigidity, and bradykinesia

Weight Gain: In a 12-week trial, the percentage of patients experiencing weight gain (>7% of baseline body weight) was 6% placebo versus 9% RISPERDAL® CONSTA®.

Maintenance Treatment: Patients should be periodically reassessed to determine the need for continued treatment.

Commonly Observed Adverse Reactions for RISPERDAL® CONSTA®: The most common adverse reactions in clinical trials (≥5%) were headache, Parkinsonism, dizziness, akathisia, fatigue, constipation, dyspepsia, sedation, weight increase, pain in extremities, and dry mouth.
