Why Propranolol is contraindicated in bronchial asthma?

Once upon a time in 1964, it was noted that propranolol, a nonselective beta-blocker, could precipitate severe bronchospasm in patients with asthma, especially at high doses. Additional small studies showed propranolol and other nonselective beta blockers could increase airway resistance.

What are the contraindications of asthma?

Who should not take BRONCHIAL ASTHMA RELIEF?

• overactive thyroid gland.
• psychotic disorder.
• closed angle glaucoma.
• high blood pressure.
• diminished blood flow through arteries of the heart.

Why is aspirin contraindicated in 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 ...

When is atenolol contraindicated?

Which beta blocker drug is contraindicated in asthma and COPD?
