<p data-start="2002" data-end="2626">A common topic in respiratory forums is the difference between inhaler device types. Metered-dose inhalers release a controlled spray of medication and may require coordination between pressing and inhaling. Dry powder inhalers are breath-activated and do not use propellants. Both are widely used in asthma and COPD treatment plans. Inhaled therapy is preferred because it targets lung tissue directly, allowing faster symptom relief compared to oral medications. Understanding device functionality and proper usage technique can significantly improve medication delivery and overall respiratory control.
