See This is the FDA Risperdal (risperidone) monograph. It gives details of clinical trials pre and post marketing of Risperdal. Most are short term trials - 6 to 8 weeks for adverse effects etc , but there are some long term trials in mice and rats. It also covers precautions and contraindications in prescribing Risperdal.
