Buprenorphine and its formulations: a comprehensive review.

Area of Science:

• Pharmacology
• Medicinal Chemistry
• Clinical Pharmacy

Background:

• Buprenorphine is a long-acting analgesic with dual applications in pain management and opioid use disorder.
• Its pharmacodynamic profile includes partial agonism at mu receptors, inverse agonism at kappa receptors, and antagonism at delta receptors.

Purpose of the Study:

• To review and compare different buprenorphine formulations.
• To highlight clinical considerations for each formulation.
• To discuss strategies for mitigating misuse of buprenorphine.

Main Methods:

• Review of existing literature on buprenorphine formulations.
• Analysis of pharmacodynamic and pharmacokinetic properties.
• Comparison of formulations based on administration route, indication, and safety profile.

Main Results:

• Multiple formulations exist for analgesia (injectable, transdermal, buccal) and opioid dependence (extended-release injectable, implant, sublingual).
• Combination products with naloxone (film, tablet) are available to deter misuse.
• Each formulation presents distinct clinical considerations regarding efficacy, safety, and patient adherence.

Conclusions:

• Buprenorphine's diverse formulations cater to specific clinical needs in analgesia and opioid use disorder.
• Understanding formulation differences is crucial for optimal therapeutic selection and patient management.
• Combination products represent an important strategy in addressing the public health challenge of opioid misuse.
