Why does aspirin cause bronchospasm?

Why does aspirin cause bronchospasm?

NSAID-induced reactions appear to be caused by the inhibition of cyclooxygenase-1 (Cox-1); this in turn activates the lipoxygenase pathway, which eventually increases the release of cysteinyl leukotrienes (Cys-LTs) that induces bronchospasm and nasal obstruction.

Does aspirin cause bronchoconstriction?

Background: Aspirin can cause bronchoconstriction in some asthmatic patients through increased production of proinflammatory mediators, particularly leukotrienes.

Can aspirin cause bronchial asthma?

Up to 20% of the asthmatic population is sensitive to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) and present with a triad of rhinitis, sinusitis, and asthma when exposed to the offending drugs. This syndrome is referred to as aspirin-induced asthma (AIA).

Why aspirin is contraindicated in bronchial asthma?

When medications such as NSAIDs or aspirin block the COX-1 enzyme, production of thromboxane and some anti-inflammatory prostaglandins is decreased, and in patients with aspirin-induced asthma, this results in the overproduction of pro-inflammatory leukotrienes, which can cause severe exacerbations of asthma and …

What causes aspirin sensitivity?

If you have asthma, nasal polyps, chronic sinusitis or chronic hives (urticaria), you’re more likely to have a reaction to aspirin or NSAIDs . When a reaction occurs, it can worsen symptoms of these conditions.

How common is aspirin-induced asthma?

Aspirin (acetylsalicylic acid)-induced asthma (AIA) consists of the clinical triad of asthma, chronic rhinosinusitis with nasal polyps, and precipitation of asthma and rhinitis attacks in response to aspirin and other NSAIDs. The prevalence of the syndrome in the adult asthmatic populations is approximately 4-10%.

What causes aspirin-induced asthma?

Aspirin-Exacerbated Respiratory Disease (Previously Termed Aspirin-Induced Asthma) Approximately 5% of patients with moderate to severe persistent asthma develop asthma when they ingest agents that inhibit cyclooxygenase, such as aspirin and other nonsteroidal anti-inflammatory drugs.

Can aspirin cause coughing?

If you have aspirin-exacerbated respiratory disease (AERD), aspirin may make you cough, wheeze and feel short of breath. Nose or sinus congestion and drainage can stuff you up and make you sneeze. “AERD usually begins in young adulthood, and is linked to a triad of symptoms,” says Dr.

What are symptoms of allergic reaction to aspirin?

Aspirin and allergy Symptoms include flushing, itchy rashes (hives), blocked and runny nose and asthma (sometimes severe), usually within an hour of taking a tablet. If you have hives (urticaria), nasal polyps or asthma, your risk of aspirin allergy is 10-30% compared to 1% in people without these conditions.

Can aspirin cause difficulty breathing?

What happens when people with AERD take aspirin or NSAIDs? Reactions usually start suddenly and can be serious. Signs and symptoms may include difficulty breathing (which could be an asthma flare-up), wheezing, coughing, sneezing, or stuffy and runny nose.

How is aspirin-induced asthma treated?

How is aspirin-induced asthma treated?

1. complete avoidance of aspirin, aspirin-containing products, and NSAIDs.
2. taking acetaminophen for occasional pain instead, or as directed by a doctor.
3. avoiding other allergy and asthma triggers, such as seasonal pollen, dust, pet dander, and stress.

What drugs can cause bronchospasm?

Bronchospasm: Classes of drugs known to cause bronchospasm include NSAIDs, aspirin, and beta-blockers. Patients with asthma and chronic obstructive pulmonary disease (COPD) are particularly prone to this phenomenon; it has been reported that up to 20% of asthmatic patients cannot tolerate aspirin and other NSAIDs.

What is aspirin-induced asthma?

Between 8-20 percent of adult asthmatics experience bronchospasm following ingestion of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs). Termed aspirin-induced asthma, this reaction is potentially fatal. Asthmatics with chronic rhinitis or a history of nasal polyps are at greater ri …

What are the side effects of aspirin in asthmatics?

Within 20 minutes to 3 hours of taking a NSAID, aspirin-sensitive asthmatics can develop symptoms such as bronchospasm, rhinorrhoea, dyspnoea, cough, or urticaria-angiodema. NSAIDs (systemic or topical) should be used with caution in asthmatics and avoided in asthmatics with nasal polyps.

Should paracetamol be used instead of aspirin for asthma patients?

NSAIDs should be used with caution in the presence of asthma and avoided in asthmatics with nasal polyps. As it is difficult to identify ‘at risk’ asthmatics, it would seem prudent to prescribe paracetamol instead of aspirin unless there are any specific contra-indications.
