The recommended inhalation technique for metered-dose inhalers (MDIs) emphasizes the importance of proper breath coordination to ensure effective medication delivery to the lungs. Shaking the inhaler before use is crucial as it ensures that the medication is properly mixed and ready to be delivered. Exhaling fully helps to clear the lungs of any residual air, allowing for a more complete inhalation of the medication.

Inhaling slowly while pressing the canister is essential because it helps to create a steady airflow that can effectively draw the medication deeper into the lungs. This technique maximizes the deposition of the drug within the airways, which is particularly important for individuals managing conditions like asthma. A slow inhalation allows for better absorption of the medication, enhancing its therapeutic effect.

Other methods, such as inhaling quickly or pressing the canister before exhaling, can lead to improper technique, resulting in suboptimal medication delivery to the airways. Holding the inhaler upside down does not align with the guidelines for using MDIs and may hinder effective inhalation and medication delivery.
