Study Details

Brief summary:

In this study, the investigators are testing a new formulation of lidocaine for its suitability in managing postoperative pain after pelvic (circumcision, inguinal, scrotal), perineal (hemorrhoidectomy) or perianal (fistulotomy) incisions. The new formulation ST-01 is a sustained release lidocaine formulation and is expected to provide pain relief over multiple days. Currently, the drug lidocaine is not available as an injectable slow-release formulation.
