Asthma improved by aspirin-like drugs
British Journal of Diseases of the Chest
|April 1, 1983
Summary
Aspirin can improve asthma symptoms and lung function in specific patients. This rare aspirin-induced bronchodilation contrasts with its potential to cause severe bronchoconstriction in others.
Area of Science:
- Pulmonology
- Clinical Pharmacology
Background:
- Bronchial asthma is a complex respiratory condition with diverse triggers and presentations.
- Some asthma patients exhibit unique sensitivities to medications, necessitating individualized treatment approaches.
Purpose of the Study:
- To investigate the bronchodilatory effects of aspirin in a specific cohort of adult asthma patients.
- To identify clinical characteristics associated with aspirin-responsive asthma.
- To explore the mechanism of aspirin-induced bronchodilation and its implications for drug safety.
Main Methods:
- Single-dose oral administration of aspirin (0.3-1.2 g) to six adult asthma patients.
- Clinical symptom assessment and pulmonary function tests before and after aspirin administration.
- Oral challenge with 12 nonsteroidal anti-inflammatory drugs in two patients to assess cyclo-oxygenase inhibitor effects.
Main Results:
- Aspirin induced significant bronchodilation and improved clinical symptoms and pulmonary function in all six patients.
- Patients responsive to aspirin shared traits: post-infectious onset, perennial course, no specific allergen links, negative skin tests, and a history of rhinorrhea or sinusitis.
- Two patients demonstrated bronchodilation with other cyclo-oxygenase inhibitors, suggesting a shared mechanism.
Conclusions:
- A rare subset of asthma patients experiences bronchodilation with aspirin and related drugs.
- Accurate diagnosis is critical, as these medications can cause dangerous bronchoconstriction in other asthma patients.
- Understanding aspirin's dual effect is vital for safe and effective asthma management.
