Beclometasone dipropionate is a potent glucocorticoid agonist; it is a prodrug of the free form, beclometasone. IC50 Value: 0.2 nM (Inhibiting thymidine incorporation) [1]Target: glucocorticoid receptorin vitro: Cortisol and beclomethasone dipropionate were more potent than salbutamol in inhibiting thymidine incorporation with IC50 values of 5 nM and 0.2 nM respectively. Cortisol 100 nM led to a 16.6 +/- 6.5% reduction and beclomethasone dipropionate 3 nM led to a 17.8 +/- 5.8% reduction in cell number [1]. in vivo: Controlled trials involving 497 adults and children demonstrated similar clinical efficacy between nebulized BDP and either nebulized fluticasone propionate or nebulized budesonide. Meta-analyses show that BDP, like other inhaled corticosteroids, has no major influence on patient height, urinary cortisol concentration, or bone metabolism [2]. Beclometasone dipropionate (BDP) 800 microgday(-1) suspension for nebulization and budesonide (BUD) 750 microg day(-1) given by nebulization in a twice-daily regimen, and when used in addition to the usual maintenance therapy, resulted in comparable clinical efficacy across all parameters [3].

Inhaled Beclometasone dipropionate/formoterol fumarate extrafine fixed combination for the treatment of asthma
Expert Rev Respir Med 2016;10(5):481-90.PMID:26938578DOI:10.1586/17476348.2016.1161508.
Inhaled therapy is often considered the cornerstone of asthma management and international guidelines recommend combination therapy of inhaled corticosteroids (ICS) and long-acting-beta2-agonists (LABA) in a large proportion of asthmatic patients. The effectiveness of ICS/LABA is dependent on the correct choice of device and proper inhalation technique, this influences drug delivery and distribution along the bronchial tree, including the most peripheral airways. The fixed combination of Beclometasone dipropionate/formoterol fumarate (BDP/FF) is the only extrafine formulation available in pressurized metered dose inhaler (pMDI) and in dry powder inhaler (DPI). Here, we focus on the recent significant advances regarding BDP/FF fixed combination for the treatment of asthma.
High-dose Beclometasone dipropionate/formoterol fumarate in fixed-dose combination for the treatment of asthma
Ther Adv Respir Dis 2016 Oct;10(5):492-502.PMID:27340255DOI:10.1177/1753465816654442.
The high-strength formulation of extrafine Beclometasone dipropionate/formoterol fumarate (BDP/Form) 200/6 µg has been developed to step up inhaled corticosteroid treatment, without increasing the dose of the bronchodilator, in patients who are not controlled with previous therapies. Two clinical studies have evaluated efficacy of high-strength BDP/Form as compared with another high-dose fixed combination and BDP monotherapy. Overall, data show that BDP/Form 200/6 μg improves lung function and has beneficial effects on symptoms, use of rescue medication and asthma control, with an acceptable safety profile comparable with that of high-dose fluticasone propionate/salmeterol. Therefore, BDP/Form 200/6 μg could be considered as an effective and safe treatment for patients with asthma who are not adequately controlled with high doses of inhaled corticosteroid monotherapy or medium doses of inhaled corticosteroid/long-acting β2-agonist combinations.
Inhaled Beclometasone dipropionate/formoterol extra-fine fixed combination in the treatment of asthma: evidence and future perspectives
Expert Opin Pharmacother 2008 Feb;9(3):479-90.PMID:18220498DOI:10.1517/14656566.9.3.479.
Background: Combinations of a long-acting beta(2)-agonist (LABA) and an inhaled corticosteroid (ICS) are effective and safe options in asthma management. Objective: To review available data on a recently developed combination of Beclometasone dipropionate (BDP) and formoterol (F) given via a pressurized metered-dose inhaler. Methods: Published data on preclinical and clinical studies were reviewed. Results/conclusion: In the treatment of asthma, BDP/F was shown to be at least as effective and well-tolerated as other available combinations of ICS and LABA with the advantage of a better cost effectiveness, and more effective in improving asthma control than BDP and formoterol given via separate inhalers. The extra-fine BDP/F combination appears to be a valuable therapeutic option in the management of asthma.
Pharmacokinetic and pharmacodynamic properties of inhaled Beclometasone dipropionate delivered via hydrofluoroalkane-containing devices
Clin Pharmacokinet 2005;44(8):815-36.PMID:16029067DOI:10.2165/00003088-200544080-00004.
Inhaled corticosteroids have a key role in the treatment of asthma and chronic obstructive pulmonary disease. In recent times, Beclometasone dipropionate has been reformulated in pressurised metered dose inhalers (pMDIs), using hydrofluoroalkanes (HFAs) as a propellant. Extensive toxicological testing has shown that HFA-propellants are well tolerated. Among the reformulated beclometasone dipropionate-containing pMDIs, only the characteristics of the two Qvar formulations have been thoroughly explored. Compared to the reference Beclometasone dipropionate formulation, the mass median aerodynamic diameter of the Qvar formulations are substantially smaller (1.1 vs 4.0 microm), whereas that of Modulite averages 2.6 microm. Scintigraphic and pharmacokinetic studies indicate a higher lung deposition for both the Qvar and the Beclazone formulations, compared with reference Beclometasone dipropionate formulation. Since the 2- to 3-fold increase in pulmonary deposition results in a 2.6- to 3-fold difference in relative efficacy for Qvar, half the dose of the reference Beclometasone dipropionate formulation has been currently recommended in adult patients with asthma, a recommendation that is supported by a large number of clinical trials. Conversely, the design of the studies conducted to compare the efficacy of Qvar with fluticasone propionate and budesonide does not allow establishing their equivalence on a milligram per milligram basis. Good studies on the bioequivalence between the reference Beclometasone dipropionate formulation and the Modulite or Beclazone formulations are not available.
The role of oral Beclometasone dipropionate in the treatment of gastrointestinal Graft-versus-Host Disease
Drugs 2009 Jul 9;69(10):1339-50.PMID:19583452DOI:10.2165/00003495-200969100-00004.
Graft-versus-host disease (GVHD) after allogeneic stem-cell transplantation causes significant morbidity and mortality. An important site of GVHD is the gastrointestinal (GI) tract because development of acute GI GVHD is prognostic of overall survival. The standard of care to treat acute GI GVHD is systemic corticosteroids and immunosuppressants; however, the use of these therapies can cause life-threatening opportunistic infections. To limit the adverse effects of systemic immunosuppression, the topically active corticosteroid Beclometasone dipropionate has been investigated in case studies and in randomized placebo-controlled trials for the treatment of acute GI GVHD. In this review, we appraise these studies with Beclometasone dipropionate, and discuss future randomized studies to clarify the role of Beclometasone dipropionate for the treatment and prevention of acute GVHD. At present, more data are required before the addition of Beclometasone dipropionate to systemic corticosteroids for the treatment of acute GVHD can be considered the standard of care.
