The study is testing a drug called **MR-107A-02** to see if it helps with pain after a surgery called **herniorrhaphy**, which fixes a hernia. This study wants to know if the drug is safe and works well for pain relief. To join, you need to have a hernia surgery planned with one side only (unilateral) and use a mesh under general anesthesia. You should have a certain level of pain after surgery, measured by a pain scale called **NRS-R** (Numerical Rating Scale for Rest) and **NRS-A** (Numerical Rating Scale for Activity). Some people can't join, like those who have had this drug before or other recent hernia repairs. If you have other medical issues like high body weight or certain stomach problems, you might not be able to join either. The study needs you to fill out forms and follow rules. If you are considering joining, here are some key points:

• The study involves a single surgery and follows your pain levels afterward.
• You must be able to read and understand the study instructions and fill out pain diaries.
• There are certain health conditions that will exclude you from participating.
