Final answer:
Administer the bronchodilator first to open up the airways, followed by the glucocorticoid inhaler for better lung penetration and effectiveness in reducing inflammation and controlling conditions such as asthma.
Step-by-step explanation:
If you are taking a glucocorticoid (steroid) inhaler for conditions such as asthma or type III hypersensitivities, and need to administer a bronchodilator, it is generally recommended to use the bronchodilator first. This sequence allows the bronchodilator to open up the airways, ensuring that the subsequent glucocorticoid has better access to the lungs and can be more effective in its anti-inflammatory action. The bronchodilator works almost immediately to expand the constricted air passages, while glucocorticoids help in the long-term control by reducing inflammation and downregulating the immune response.
