Brief summary

The purpose of this study is to evaluate whether the combination therapy of opiranserin and acetaminophen is non-inferior to the combination of non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen for postoperative pain management after minimally invasive cholecystectomy. This is a single-center, randomized, controlled, non-inferiority clinical trial in adult patients undergoing minimally invasive cholecystectomy. Participants will be randomly assigned to either the Treatement group (opiranserin + acetaminophen) or the control group (NSAIDs + acetaminophen) in a 1:1 ratio to compare the analgesic efficacy and safety between the two analgesic regimens.

Interventions

DRUGOpiranserin+Acetaminophen

In the Opiranserin+Acetaminophen group, opiranserine 1000mg infusion will be provided over 10 hr. Opiranserin infusion will be started after the indduction of anesthesia. After laoding dose (160mg ) over 30 minutes, maintenace dose (840mg) will be infused over 9hr 30min. IV Acetaminophen 1g will be provided q 8h until 24 h potperatively.

DRUGAcetaminophen+NSAIDs

In the Acetaminophen+NSAIDs group, Normal saline 500 ml will be provided over 10hr. IV Acetaminophen 1g and ibuprofen 300mg will be provided q 8h until 24 h potperatively.
