Brief Summary  
Postoperative pain is one of the main issues in postoperative care and plays an important role
in accelerating the improvement of surgical patient’s general condition 1 . Female patients have
worse quality of recovery after surgery than male patients. The greater propensity for pain
and opioid-related side effects are likely contributing factors for poor postsurgical recovery in
women. Hysterectomy is a commonly performed surgical procedure in women, and it often
results in significant pain and slow recovery 2 . One of the strategies to prevent chronic
postoperative pain is to reduce the acute pain in the initial phase using effective medications
with the least side effects. Nevertheless, pharmacologic strategies to improve global quality
of recovery after hysterectomy have yet to be examined 2 .
In this study, we intended to evaluate the effect of perioperative administration of oral
Duloxetine on postoperative pain and recovery in patients undergoing hysterectomy.

Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor (SNRI) commonly
used to treat depression, anxiety and chronic pain. The medication works by increasing the
levels of serotonin and norepinephrine in the brain, which can help to reduce pain, improve
mood and promote relaxation. Duloxetine has also been found to have a mild analgesic effect
and has been investigated as a premedication for various surgical procedures, including
hysterectomy. Duloxetine premedication in hysterectomy effectively reduces pain and
improves patient satisfaction. Duloxetine has been shown to improve the quality of
anaesthesia, reduce the need for additional pain medication and cause lesser adverse events
when compared to those who do not receive premedication.

This study aims to investigate the efficacy and safety of perioperative oral Duloxetine on
quality of recovery and as an analgesia in adult patients undergoing hysterectomy and the
Quality of Recovery-40 questionnaire (QoR-40) shall be used for evaluation.
