The acute management of asthma

Area of Science:

• Pulmonology
• Emergency Medicine
• Pharmacology

Background:

• Acute asthma exacerbations (AAE) present significant clinical challenges in emergency departments and clinics.
• Treatment response varies widely among patients, necessitating a flexible therapeutic approach.

Purpose of the Study:

• To provide a comprehensive overview of pharmaceutical treatments for AAE.
• To guide clinicians in selecting appropriate therapies for immediate AAE management and long-term prevention.

Main Methods:

• Review of current guidelines and literature on AAE pharmacotherapy.
• Analysis of the role of various respiratory medications in acute settings versus long-term management.

Main Results:

• High-dose nebulized short-acting beta2-agonists (SABA) combined with short-acting muscarinic antagonists (SAMA) form the cornerstone of initial AAE treatment.
• Early administration of oral or parenteral corticosteroids is vital for preventing ICU or hospital admission.
• Adjunctive therapies like intravenous magnesium and helium/oxygen mixtures should be considered early.
• Long-term agents (e.g., inhaled corticosteroids, long-acting beta2-agonists) are important for preventing readmissions but not for immediate AAE treatment.

Conclusions:

• Clinicians must be adept at utilizing the full spectrum of asthma medications for acute exacerbations.
• Strategic initiation of maintenance therapies at discharge is key to reducing future exacerbations and hospitalizations.
