Inflammatory conditions, including asthma, dermatoses, and allergic rhinitis, involve the activation of cascades by inflammatory mediators. Inflammation is a primary defense mechanism and the homeostatic response of the immune system; however, a prolonged inflammatory response in certain disorders may lead to tissue damage, pain, and swelling. Beclomethasone dipropionate works by attenuating the inflammatory responses associated with asthma, allergic rhinitis, nasal polyps, and corticosteroid-responsive dermatoses. It suppresses the actions of inflammatory cells, such as mast cells, eosinophils, basophils, lymphocytes, macrophages, and neutrophils. It also inhibits the release of inflammatory mediators, such as histamine, eicosanoids, leukotrienes, and cytokines. Beclomethasone dipropionate is reported to exhibit potent topical activity while possessing low systemic effects. Beclomethasone dipropionate is a corticosteroid drug with anti-inflammatory and vasoconstrictive effects used to treat chronic inflammatory processes such as asthma, allergic rhinitis, corticosteroid-responsive dermatoses. When inhaled, it improves lung function, decreases airway hyper-reactivity, and reduces the severity of asthmatic symptoms. Although inhaled corticosteroids, including beclomethasone dipropionate, are reported to mainly act locally in the lungs, systemic effects such as disruption of hypothalamic-pituitary-adrenal (HPA) axis function, bone turnover, osteoporosis, and growth suppression may still be observed with chronic use or high dose administration. There were varying findings from clinical studies examining the effect of beclomethasone dipropionate on growth suppression in pediatric patients. It was shown to suppress the hypothalamo-pituitary-adrenal (HPA) axis in a dose-dependent manner. HPA axis is a central hormonal response system to stress and activation of HPA axis leads to the production of endogenous steroid hormone production. Long-term use of high-dose systemic

Beclomethasone dipropionate is a corticosteroid and prodrug that is rapidly activated by hydrolysis to the active monoester, 17 monopropionate (17-BMP), which mediates anti-inflammatory actions. 17-BMP has been shown _in vitro_ to exhibit a binding affinity for the human glucocorticoid receptor which is approximately 13 times that of dexamethasone and 25 times that of beclomethasone dipropionate. Upon binding of the ligand, the glucocorticoid receptors dimerize and translocate into the nucleus, where they subsequently bind to glucocorticoid response elements (GRE) on glucocorticoid-responsive genes, leading to changes in transcription. There are several proposed mechanisms for the anti-inflammatory action of corticosteroids. Corticosteroids may work by increasing the transcription of genes coding for anti-inflammatory proteins, including lipocortin-1 and interleukin-10. Corticosteroids were also shown to inhibit the expression of multiple genes that encode pro-inflammatory factors, such as cytokines, chemokines, and adhesion molecules, that are activated during the chronic inflammatory process. This is thought to be due to the direct inhibitory interaction between activated glucocorticoid receptors and activated pro-inflammatory transcription factors, such as nuclear factor-kappa B and activator protein-1. Chronic inflammation is often characterized by enhanced expression of these transcription factors that bind to and activate coactivator molecules, which then acetylate core histones to switch on gene transcription to further amplify the inflammatory process. Corticosteroids suppress the multiple inflammatory gene expression by promoting histone deacetylation, resulting in tighter coiling of DNA and reduced access of transcription factors to their binding sites.
