Beclomethasone dipropionate in Crohn's ileitis: A randomised, double-blind trial.

2011

Abstract Background Steroids, the mainstay of Crohn's disease treatment, have been associated with systemic side effects. Aim To evaluate the efficacy and tolerability of beclomethasone dipropionate for maintaining remission induced by a short course of systemic steroids in patients with Crohn's ileitis with or without right colonic involvement. Methods Patients (n = 84) with active Crohn's disease who achieved remission during a 2-week prednisone run-in period were randomised to receive beclomethasone dipropionate for 24 weeks or continue prednisone for a further 2 weeks followed by placebo for 22 weeks. The primary outcome was relapse rate (Crohn's Disease Activity Index score > 150 and a…

Beclomethasone dipropionate hydrofluoroalkane for the treatment of allergic rhinitis

2016

Allergic rhinitis (AR) is a common respiratory disease, and its prevalence is increasing all over the world, both in adults and in children. Patients experience symptoms that may negatively impact on physical, social and psychological well-being. Hence, if left untreated, allergic rhinitis may significantly affect quality of life. Under current guidelines, intranasal corticosteroids are considered the most effective drugs and they are recommended as first-line therapy. Among the several corticosteroid intranasal sprays available, beclomethasone dipropionate is one of the most prescribed. Recently, new intranasal hydrofluoroalkane-propelled formulations with little or no impact on the ozone …

Phospholipid-polyaspartamide micelles for pulmonary delivery of corticosteroids

2011

A novel drug delivery system for beclomethasone dipropionate (BDP) has been constructed through self-assembly of a pegylated phospholipid-polyaminoacid conjugate. This copolymer was obtained by chemical reaction of α,β-poly(N-2-hydroxyethyl)-DL-aspartamide (PHEA) with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethyleneglycol)2000] (DSPE-PEG(2000)-NH(2)). Benefiting from the amphiphilic structure with the hydrophilic shell based on both PHEA and PEG and many hydrophobic stearoyl tails, PHEA-PEG(2000)-DSPE copolymer was able to self assemble into micelles in aqueous media above a concentration of 1.23 × 10(-7)M, determined by fluorescence studies. During the self-assembling …

Effects of Beclomethasone dipropionate and Formoterol in reducing oxidative stress induced by cigarette smoke extracts and IL-17

2011

Rationale: Oxidative stress is involved in airway inflammatory diseases. Inhaled-corticosteroids reduce airway inflammation and the combination with long-acting β2 agonists enhances this effect. Objective: to investigate whether Cigarette smoke extracts (CSE) and Interleukin-17A (IL-17A) activate airway epithelial cells to release markers of oxidative/nitrosative stress and to investigate the effect of beclomethasone dipropionate (BDP) and formoterol. Methods: Human bronchial epithelial cells (16HBE) were stimulated with different concentrations of CSE (from 0 to 10%) to evaluate the expression of IL-17 receptor (IL-17R). 16HBE were also stimulated with CSE (2.5%) with and withouth rhIL-17A…

Comparative Effect of Beclomethasone Dipropionate and Cetirizine on Acoustic Rhinometry Parameters in Children With Perennial Allergic Rhinitis: A Ra…

2018

Background and objectives The effect of intranasal corticosteroids and oral antihistamines on acoustic rhinometry parameters has not been directly compared. The primary objective was to compare the effect of a 21-day course of treatment with nasal beclomethasone dipropionate (nBDP) with that of cetirizine (CTZ) on nasal patency measured using acoustic rhinometry in children with perennial allergic rhinitis (PAR). The secondary objective was to compare the effect of both drugs on nasal cytology, symptom severity, sleep quality, and quality of life. Methods In this 21-day, open-label, randomized controlled study, 34 children with PAR (age 6-14 years) with a Total 5-Symptom Score (T5SS) ≥5 rec…

Realization of polyaspartamide-based nanoparticles and in vivo lung biodistribution evaluation of a loaded gucocorticoid after aerosolization in mice

2016

Abstract In this study, novel polymeric nanoparticles (NPs) were developed and their potential as carriers for beclomethasone dipropionate (BDP) into the lung after aerosolization was demonstrated by in vivo studies in mice. In particular, these NPs were obtained starting from two polyaspartamide-based copolymers which were synthesized by chemical reaction of α,β-poly(N-2-hydroxyethyl)- dl -aspartamide (PHEA) and its pegylated derivative (PHEA-PEG2000) with poly(lactic acid) (PLA). To obtain nanosized particles, the high pressure homogenization (HPH)—solvent evaporation method was followed by using an organic phase containing both PHEA-PLA and PHEA-PEG2000-PLA (at a weight ratio equal to 1:…
