Clinical Trials Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.

During clinical development, 1,156 patients were exposed to DYLOJECT in multiple-dose, controlled and open-label studies. DYLOJECT was administered post-surgically every 6 hours for up to 5 days. The incidence rates of adverse reactions listed in the following table are derived from multicenter, controlled clinical studies in post-operative patients comparing DYLOJECT to placebo in patients who may have also received morphine rescue medication.
