Which medication is commonly used via inhaler for respiratory conditions?

Albuterol is commonly used in inhaler form to treat respiratory conditions, particularly asthma and chronic obstructive pulmonary disease (COPD). It is a bronchodilator that works by relaxing the muscles in the airways, leading to wider air passages and making it easier for patients to breathe. This medication is often delivered through a metered-dose inhaler or nebulizer, providing rapid relief from acute bronchospasm.

On the other hand, adrenaline is typically used in emergency situations for severe allergic reactions and cardiac arrest, while aspirin is primarily an antipyretic and anti-inflammatory medication, not specifically indicated for respiratory disorders. Atropine, which is used to treat bradycardia and certain types of nerve agent poisoning, does not have a primary role in the management of respiratory conditions. Therefore, albuterol stands out as the appropriate choice for patients experiencing respiratory distress.
