Cutaneous Drug Reactions in the Elderly.

Area of Science:

• Dermatology
• Pharmacology
• Internal Medicine

Background:

• Cutaneous adverse drug reactions (CADRs) represent a substantial portion of all adverse drug reactions.
• These reactions can present with diverse clinical manifestations, often mimicking other dermatologic or systemic conditions.
• CADRs carry the potential for significant patient morbidity and mortality.

Purpose of the Study:

• To outline the most common morphologic groups of cutaneous adverse drug reactions.
• To emphasize the clinical significance and potential severity of CADRs.
• To highlight the particular vulnerability of older individuals to drug reactions.

Main Methods:

• Review and categorization of common cutaneous adverse drug reaction syndromes.
• Classification based on seven distinct morphologic groups.
• Consideration of clinical implications and patient populations.

Main Results:

• Identification of seven primary morphologic categories for CADRs: exanthematous, dermatitic/eczematous, urticarial, pustular, blistering, purpuric, and erythrodermic.
• Recognition of the broad spectrum of presentations for drug-induced skin conditions.
• Acknowledgement of the heightened risk and potential for severe consequences in the elderly.

Conclusions:

• Effective management of CADRs requires accurate identification and classification.
• The diverse presentations of CADRs necessitate a high index of suspicion.
• Special attention must be paid to the management of CADRs in older adults due to potential downstream consequences.
