[NSAID urticaria: Similar management to acute urticaria]

Area of Science:

• Pharmacology
• Immunology
• Dermatology

Background:

• Non-steroidal anti-inflammatory drugs (NSAIDs) are frequent triggers of immediate hypersensitivity reactions.
• Acute urticaria is the most common manifestation, often presenting as a non-allergic pharmacological side effect.
• This reaction stems from NSAID-induced alterations in arachidonic acid metabolism.

Purpose of the Study:

• To review urticaria reactions induced by NSAIDs.
• To highlight the clinical diagnosis and management of NSAID-induced urticaria.
• To discuss the role of cyclooxygenase (COX) inhibition in these reactions.

Main Methods:

• Clinical diagnosis based on patient history and reaction patterns.
• Review of existing literature on NSAID hypersensitivity and urticaria.
• Analysis of pharmacological mechanisms involving arachidonic acid pathways.

Main Results:

• NSAID-induced urticaria is a common, clinically diagnosed condition.
• The reaction is a pharmacological effect, not a true allergic response.
• Selective COX-2 inhibitors are generally well-tolerated alternatives.

Conclusions:

• NSAID-induced urticaria is manageable through avoidance and strategic drug selection.
• Understanding COX-1 and COX-2 inhibition is key to managing NSAID hypersensitivity.
• This review simplifies the approach to NSAID-related urticaria management.
