How is Salbutamol administrated using an MDI?

Salbutamol, a bronchodilator used to relieve bronchospasm in conditions such as asthma or COPD, can be effectively administered via a metered-dose inhaler (MDI). The correct administration method for MDI indicates that the standard dosing typically involves delivering 100 micrograms (mcg) in one puff. This dosing is designed to provide adequate relief while minimizing the risk of side effects from over-administration.

The recommendation of taking 1 puff every 4 breaths is also aligned with established guidelines for usage, as it helps ensure that the medication is administered effectively while allowing for adequate time between doses for the patient to assess the effectiveness of the medication and respond as needed.

By ensuring that the patient puffs at a reasonable interval, the likelihood of properly inhaling the medication into the lungs is increased. This method contributes not only to the effectiveness of the treatment but also ensures patient safety by preventing excessive dosing, which could lead to potential side effects such as tachycardia or jitteriness.

In practice, while dosages can vary based on individual patient needs and specific treatment plans, adherence to established dosing guidelines is crucial for optimal management of airway constriction.
