What does it mean to inhale SABA via MDI?

Administering SABA via MDI refers to the therapeutic method of inhaling short-acting β₂-adrenergic agonists through a metered-dose inhaler, with specific details as follows:

Administering SABA via MDI is a common treatment for airway diseases such as asthma and chronic obstructive pulmonary disease (COPD). MDI stands for metered-dose inhaler, a drug delivery device that stores medication in a pressurized container. SABA, or short-acting β₂ agonists, can rapidly relax bronchial smooth muscles and relieve symptoms such as chest tightness and wheezing caused by airway spasms. This delivery method allows medication, in the form of fine particles generated by the aerosol, to directly reach the airway mucosa, resulting in quick onset of action and minimal systemic side effects. It effectively alleviates breathing difficulties and is suitable for emergency treatment during acute episodes or for daily symptom control.

Proper technique is essential when using an MDI to ensure effective drug delivery to the lungs. Medication should be replaced regularly as prescribed, and expired products must be avoided. The inhaler device should be kept clean, with the nozzle wiped promptly after each use. Exposure to airway irritants such as dust and pollen should be minimized. Staying warm to prevent colds and reducing triggers of disease exacerbations are also important. Patients should carry their medication at all times for immediate use in case of sudden symptoms.
