Steroids such as corticosteroids are potent anti-inflammatory drugs that are used to treat conditions like acute inflammation and allergic reactions, though they can cause side effects like increased fat redistribution and risk of infection; other anti-inflammatory drugs include inhaled corticosteroids like beclomethasone and fluticasone to prevent airway inflammation, as well as leukotriene inhibitors and cromolyn sodium which are also used to prevent airway inflammation with fewer side effects than steroids.
