What side effects are associated with this type of intervention?

Common treatments in Enhanced Recovery After Surgery (ERAS) protocols that aim to enhance gastrointestinal motility and reduce inflammation include prokinetic agents like metoclopramide and erythromycin, as well as anti-inflammatory medications. Metoclopramide can cause side effects such as tardive dyskinesia, extrapyramidal symptoms, and drowsiness. Erythromycin, while effective in accelerating gastric emptying, can lead to gastrointestinal disturbances like nausea, vomiting, and abdominal pain. Anti-inflammatory medications, depending on their class, may cause gastrointestinal irritation, increased risk of bleeding, and renal impairment. TU-100 (Daikenchuto), being a traditional Japanese medicine, is generally well-tolerated but may cause mild gastrointestinal symptoms such as diarrhea or abdominal discomfort in some patients.

What prior FDA approvals exist?

FDA-approved treatments for Enhanced Recovery After Surgery (ERAS) that are similar to TU-100, which aims to enhance gastrointestinal motility and reduce inflammation, include medications like alvimopan and methylnaltrexone. Alvimopan is a peripherally acting mu-opioid receptor antagonist that helps accelerate the time to gastrointestinal recovery following surgeries that include bowel resection. Methylnaltrexone, another peripherally acting mu-opioid receptor antagonist, is used to treat opioid-induced constipation, which can be a component of postoperative ileus. Both drugs work by improving bowel motility, similar to the proposed effects of TU-100.

What other types of research exist?

Promising alternatives to TU-100 for ERAS patients include: 1) Erythromycin, which accelerates gastric emptying and has prokinetic effects. 2) Domperidone, which enhances gastrointestinal motility and is effective in treating gastroparesis. 3) Metoclopramide, which also promotes gastric emptying and reduces symptoms of gastroparesis. These alternatives have shown efficacy in enhancing gastrointestinal motility and could be considered for aiding in the resolution of postoperative ileus.

Summary

This trial is testing TU-100, an herbal medicine, to see if it helps patients recover faster from bowel surgery. It targets patients who often have trouble with their intestines not working properly after surgery. The medicine may help by reducing inflammation and getting the intestines moving again. Daikenchuto (TU-100) is a traditional Japanese herbal medicine made from ginger, ginseng, and Japanese pepper, commonly used for various intestinal disorders and postoperative recovery.

Who is the study for?

Adults over 18, able to consent and follow study procedures, undergoing elective bowel resection surgery. They must use effective contraception if of childbearing potential. Excluded are those with recent heart attacks, certain surgeries or conditions that could affect results or pose risks, uncontrolled illnesses like severe heart failure or arrhythmias, compromised immune systems, pregnant or lactating women, and anyone using certain supplements.

What is being tested?

The trial is testing TU-100's effectiveness in speeding up recovery from postoperative ileus (delayed bowel function) after bowel resection surgery compared to a placebo. Participants will be randomly assigned to either the TU-100 group or the placebo group without knowing which one they receive.

What are the potential side effects?

Specific side effects aren't listed for TU-100; however, participants should report any unusual symptoms as they may relate to the intervention. Common surgical recovery issues may include pain at the incision site, nausea, constipation or diarrhea.

Other Research

Enhanced Recovery After Surgery (ERAS) protocols often include treatments aimed at improving gastrointestinal motility and reducing inflammation to expedite recovery. TU-100, a traditional Japanese medicine, enhances gastrointestinal motility and reduces inflammation, which can help resolve postoperative ileus—a common complication that delays recovery. By promoting bowel function and reducing inflammatory responses, treatments like TU-100 can significantly improve patient outcomes, reduce hospital stays, and enhance overall recovery in ERAS patients.
