metered-dose inhalers

Metered-dose inhalers (MDIs) are handheld devices that deliver a specific dose of medication directly to the lungs to treat respiratory conditions like asthma or COPD. They work by releasing a puff of aerosolized medicine when pressed, which users inhale through a mouthpiece. This targeted delivery helps reduce symptoms, improve airflow, and control episodes. Proper technique, including coordinating inhalation with activation, enhances effectiveness. MDIs are portable, convenient, and widely used, often containing a propellant to help deliver consistent doses. Regular cleaning and correct usage are important for optimal results.
