Advanced Pharmacology Short term treatment options for asthma in a child include oral corticosteroids, which are often used to gain prompt control of poorly controlled persistent asthma, or when starting long-term therapy. It is used for short-term (3-10 days) burst, broad anti-inflammatory effects. Long-term control medications include corticosteroids to block late-phase reaction to allergen, reduce airway hyper responsiveness, and inhibit inflammatory cell migration and activation. They are the most potent and effective anti-inflammatory medication currently available. Inhaled corticosteroids (ICSs) are used in the long-term control of asthma. Short courses of oral systemic corticosteroids are often used to gain prompt control of the disease when initiating long-term therapy; long-term oral systemic corticosteroid is used for severe persistent asthma.
