Understanding NSAIDs: from aspirin to COX-2

Area of Science:

• Pharmacology
• Internal Medicine
• Drug Development

Background:

• Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used, with millions of prescriptions and over-the-counter sales annually in the US.
• Despite their long history, NSAIDs exhibit paradoxes, ranging from infant-safe OTC options to potent prescription drugs causing severe adverse events.

Purpose of the Study:

• To provide practitioners with a comprehensive overview of NSAID types, including novel cyclooxygenase-2 (COX-2) selective inhibitors.
• To discuss the mechanism of action, efficacy, and potential adverse reactions associated with various NSAIDs.
• To explore emerging nontraditional applications and a new framework for NSAID development.

Main Methods:

• Review of existing literature on NSAID pharmacology and clinical use.
• Analysis of trends in NSAID prescription and over-the-counter sales.
• Examination of the development and market introduction of new NSAID formulations, including COX-2 inhibitors.

Main Results:

• NSAID use is increasing, driven by OTC availability and an aging population with conditions like osteoarthritis.
• Newer COX-2 selective inhibitors rapidly gained popularity upon their introduction.
• A spectrum of NSAID safety and efficacy exists, posing choices for prescribers.

Conclusions:

• Understanding the diverse profiles of NSAIDs, including newer COX-2 agents, is crucial for effective and safe patient management.
• Ongoing research is expanding the therapeutic landscape for NSAIDs beyond traditional indications.
• A evolving framework supports the development of future NSAID medications.
