Adjuvant Analgesics in Acute Pain Management

Area of Science:

• Veterinary Medicine
• Pharmacology
• Pain Management

Background:

• Adjuvant analgesics, including gabapentin, tramadol, and ketamine, are frequently utilized in small animal veterinary practice.
• These medications are typically prescribed for outpatient use, particularly when pain is unresponsive to conventional analgesics such as opioids, local anesthetics, and nonsteroidal anti-inflammatory drugs (NSAIDs), or when NSAIDs are contraindicated.

Purpose of the Study:

• To review the mechanisms of action, clinical applications, adverse effects, and existing evidence for adjuvant analgesics in treating acute pain in companion animals.
• To highlight the role of these drugs as potential alternatives for reducing or replacing opioid use in veterinary pain management.

Main Methods:

• Literature review of scientific articles and clinical studies on adjuvant analgesics in companion animals.
• Analysis of pharmacological properties, efficacy data, and safety profiles of commonly used adjuvant analgesics.

Main Results:

• Gabapentin, tramadol, and ketamine demonstrate varied mechanisms of action and clinical utility in managing refractory pain.
• Evidence supports their use in specific acute pain scenarios, offering alternatives to traditional analgesics.
• Potential adverse effects and contraindications were identified for each agent.

Conclusions:

• Adjuvant analgesics are valuable tools for managing acute pain in companion animals, especially in challenging cases.
• These drugs provide viable options for opioid-sparing strategies in veterinary pain management.
• Further research may elucidate optimal protocols and expand the application of these analgesics.
