About this trial
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.

Treatments tested in this trial
Opiranserin+Acetaminophen
DrugIn 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.
Acetaminophen+NSAIDs
DrugIn 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.
Treatment groups
Trial outcomes
Primary outcomes
Area under the curve of the pain score at rest through 12 hours (NRS·h)
Area under the curve of the numeric rating scale pain score at rest through 12 hours (Numerical Rating Scale·h), Pain score will be assess with the numerical rating scale (NRS), ranging from 0 (0, no pain) to 10 (maximum, worst pain), higher scores indicate greater pain intensity.
Secondary outcomes
Area under the curve of the pain score at rest through 24 hours
Area under the curve of the numeric rating scale pain score at rest through 24 hours. Area under the curve of the numeric rating scale pain score at rest through 24 hours (Numerical Rating Scale·h), Pain score will be assess with the numerical rating scale (NRS), ranging from 0 (0, no pain) to 10 (maximum, worst pain), higher scores indicate greater pain intensity.
opioid consumption
pain at rest
numeric rating scale pain score at rest, Pain score will be assess with the numerical rating scale (NRS), ranging from 0 (0, no pain) to 10 (maximum, worst pain), higher scores indicate greater pain intensity.
pain during movement
numeric rating scale pain score during movement Pain score will be assess with the numerical rating scale (NRS), ranging from 0 (0, no pain) to 10 (maximum, worst pain), higher scores indicate greater pain intensity.
