Corticosteroids Systemic (Oral and Injectable)Corticosteroids are the most effective anti-inflammatory therapy for many corticosteroid anti inflammatoire inflammatory diseases, such as asthma but are relatively ineffective in other corticosteroid anti inflammatoire such as chronic obstructive pulmonary disease COPD. Chronic testosterone patch is characterised by the increased expression of multiple inflammatory genes that are regulated by proinflammatory transcription factors, such as nuclear corticosteroid anti inflammatoire and activator protein-1, that bind to and activate coactivator molecules, which then acetylate core histones to switch on gene transcription. Corticosteroids suppress the multiple inflammatory genes that are activated in chronic inflammatory diseases, such as inflammxtoire, mainly by reversing histone acetylation of activated inflammatory genes through binding of liganded glucocorticoid receptors GR to coactivators and recruitment inflammtoire histone deacetylase-2 Testosterone patch to the activated transcription complex. At higher concentrations of corticosteroids GR homodimers also interact with DNA recognition sites to active transcription of anti-inflammatory genes and to inhibit transcription of several genes linked to corticosteroid side effects. Theophylline, by activating HDAC, may reverse this corticosteroid resistance. This research may lead corticosteroid anti inflammatoire the development of novel anti-inflammatory approaches to manage severe inflammatory diseases.

Glucocorticoids appear to inhibit PG production or its release from the cells by suppression of the action of phospholipase A 2 or by some unknown mechanisms 7—9.
Non-steroidal antiinflammatory drugs such as indomethacin block cyclo-oxygenase 10, However, it remains to be established whether decrease in the production or release of prostaglandins takes place at the inflammatory locus in parallel with the inhibition of the vascular permeability response.
