Stopped early · Phase 2 · Has a placebo group

Conditions studied: Pain, Post-operative

In brief

The primary objective of this study is to evaluate the analgesic efficacy of two dose levels of DEX-IN compared with placebo, using the summed pain intensity difference over the first 48 hours (SPID48) in subjects with acute moderate to severe pain following unilateral bunionectomy.
