Clinical Pharmacology of Corticosteroids

Williams, Dennis M·2018·Respiratory Care

Abstract

Corticosteroids have numerous applications in treating inflammation and diseases of immune function based on their significant anti-inflammatory and immunosuppressive effects. Corticosteroids modulate immune function through various effects in the nucleus of numerous cells. When used in pharmacologic doses to suppress allergic responses or inflammation, these agents can cause numerous adverse effects associated with an excess of glucocorticoid activity. Prolonged use (>2 wk) results in suppression of the hypothalamic-pituitary-adrenal axis, which requires tapering of doses. Dosing strategies for systemic corticosteroids are designed to minimize the risk for hypothalamic-pituitary-adrenal axis suppression. Topical administration of corticosteroids, including oral inhalation, is often used to avoid the significant adverse effects associated with chronic use. Inhaled corticosteroids are potent synthetic agents that exert their actions locally in the airways but can cause systemic effects based on several factors that influence systemic bioavailability. Inhaled corticosteroids are the cornerstone of asthma therapy and important options for COPD in patients who experience frequent exacerbations. By the nasal route, they are the most effective therapy for treating moderate-to-severe allergic rhinitis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
