For the Treatment of Schizophrenia
In a 12-week, double-blind, placebo-controlled trial in patients with schizophrenia, patients taking RISPERDAL® CONSTA® experienced significant improvement vs placebo, as measured by the Positive and Negative Syndrome Scale (PANSS) total scores (P≤0.002).§ ||4,5
Percentage of improvement in PANSS total scores at 12 weeks4,5

- Mean change at last observation carried forward (LOCF) endpoint was 2.6 for placebo, -6.2 for the 25-mg group, and -8.5 for the 50-mg group4,5
- LOCF scores at endpoint were 84.6 for placebo, 75.5 for the 25-mg group, and 73.8 for the 50-mg group4,5
- Differences at endpoint for the 25-mg and 50-mg groups were statistically significant vs placebo (P≤0.002)4,5

Proven Safety and Tolerability§
RISPERDAL® CONSTA® has a proven safety profile in the treatment of schizophrenia
- Incidence of weight gain >7% of body weight was 9% for RISPERDAL® CONSTA® vs 6% for placebo at endpoint1
- Discontinuation rate due to adverse events was comparable with that of placebo (11% with RISPERDAL® CONSTA® vs 13% with placebo)1
- The most common adverse reactions in clinical trials in patients with schizophrenia (≥5%) were headache, Parkinsonism, dizziness, akathisia, fatigue, constipation, dyspepsia, sedation, weight increased, pain in extremity, and dry mouth1
§Demonstrated in a 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group trial of 400 patients with schizophrenia.
-
-
- Patients received intramuscular (IM) injections of placebo or RISPERDAL® CONSTA® (25, 50, or 75 mg) every 2 weeks5
- Patients also received oral antipsychotic supplementation for the first 3 weeks to allow RISPERDAL® CONSTA® to reach therapeutic levels5
- The primary measure of efficacy was change in PANSS total scores from baseline to endpoint5
-
||The PANSS is a composite scale of 30 items used to assess positive symptoms, negative symptoms, and general psychopathology. For each item, as well as the total score, a higher score represents a worse condition. Lower PANSS scores indicate improvement.6
