What side effects are associated with this type of intervention?

Common treatments for acute pain include opioids, NSAIDs, and acetaminophen. Opioids, such as hydrocodone and oxycodone, can cause side effects like constipation, sedation, nausea, and pruritus. NSAIDs, including ibuprofen and diclofenac, are associated with gastrointestinal issues, renal impairment, and increased risk of bleeding. Acetaminophen is generally well-tolerated but can lead to liver toxicity, especially at high doses or with prolonged use.

What prior FDA approvals exist?

The FDA has approved several analgesics for the treatment of acute pain, including nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and diclofenac, acetaminophen, and opioid analgesics such as tramadol and oxycodone. These medications are commonly used for their efficacy in reducing pain and inflammation. Additionally, intravenous acetaminophen is used for patients unable to take oral medication or requiring rapid onset of analgesia. The investigational drug MR-107A-02 is being studied for its efficacy and safety in treating acute postoperative pain, similar to these approved analgesics.

What other types of research exist?

Promising novel alternatives to MR-107A-02 for acute pain management include AZD1940, although it did not show significant efficacy compared to placebo in post-operative pain after lower third molar surgery. Another alternative is tenoxicam, which demonstrated significant analgesic efficacy in post-operative pain management after abdominal or orthopedic surgery. Additionally, investigational approaches targeting nerve growth factor for osteoarthritis pain and multimodal analgesic strategies incorporating drugs like ketorolac and acetaminophen are also noteworthy.

Summary

This trial is testing a new medication called MR-107A-02 to see if it can safely and effectively reduce pain in patients who have had hernia surgery.

Who is the study for?

This trial is for individuals experiencing acute pain after undergoing herniorrhaphy, which is surgery for a hernia repair. Specific eligibility criteria are not provided, but typically participants must be adults who have just had this surgery and meet certain health standards.

What is being tested?

The study is testing the effectiveness and safety of a medication called MR-107A-02 in managing post-surgery pain. It's being compared to Tramadol, a known pain reliever, and a placebo (a substance with no active drug).

What are the potential side effects?

While specific side effects are not listed here, generally medications like MR-107A-02 could cause nausea, dizziness, or sleepiness. Tramadol may also lead to similar side effects including constipation or headaches.

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

The most common treatments for acute pain include NSAIDs and opioids. NSAIDs reduce pain and inflammation by inhibiting cyclooxygenase (COX) enzymes, which decreases prostaglandin production. Opioids alleviate pain by binding to opioid receptors in the central nervous system, blocking pain signals and altering pain perception. These mechanisms are important for acute pain patients as they guide the selection of appropriate medications, ensuring effective and timely pain relief tailored to the pain's intensity and cause.
