Corticosteroids for exacerbations of asthma and copd

Glucocorticoids are potent anti-inflammatories, regardless of the inflammation's cause; their primary anti-inflammatory mechanism is lipocortin-1 (annexin-1) synthesis. Lipocortin-1 both suppresses phospholipase A2 , thereby blocking eicosanoid production, and inhibits various leukocyte inflammatory events ( epithelial adhesion , emigration , chemotaxis , phagocytosis , respiratory burst , etc.). In other words, glucocorticoids not only suppress immune response, but also inhibit the two main products of inflammation, prostaglandins and leukotrienes . They inhibit prostaglandin synthesis at the level of phospholipase A2 as well as at the level of cyclooxygenase /PGE isomerase (COX-1 and COX-2), [29] the latter effect being much like that of NSAIDs , potentiating the anti-inflammatory effect.

Studies on corticosteroids tend to lean toward the extreme use, rather than the average use.  For example, some studies look at corticosteroids for extreme and rarer cases of eczema.  This makes it harder to research what long-term studies are out there on steroid use.  To complicate things further, corticosteroids can be oral, topical, injected, or inhaled, and this dramatically changes the benefits and risks, and in turn the short-term and long-term effects.  Speak with your doctor and pharmacist on what, if any, long-term studies out there are relevant to your own medical treatment.

Da Corticosteroide eine Magensäureüberproduktion induzieren, sollte bei dauerhafter Gabe zusätzlich ein Protonenpumpenhemmer genommen werden, um die Entstehung eines Magenulkus zu verhindern. Allgemein kann, insbesondere bei langfristiger und/oder hochdosierter Anwendung, eine große Zahl von Nebenwirkungen auftreten (z. B. Cushing-Syndrom , siehe auch Absatz Überproduktion ), die eine sorgfältige Abwägung bei der Anwendung erforderlich machen. Bei einer Stoßtherapie im Bereich der Behandlung von Epilepsie oder eines Multiple-Sklerose -Schubes muss etwa eine Stunde nach der Einnahme einer Dosis ein Magenschutzmittel verabreicht werden.
