In the crystal structure of (8S,9R,10S,11S,13S,14S,16S,17R)-9α-bromo-11-hydr-oxy-10,13,16-trimethyl-3-oxo-17-[2-(propion-yloxy)acet-yl]-6,7,8,9,10,11,12,13,14,15,16,17-dodeca-hydro-3H-cyclo-penta-[a]phenanthren-17-yl propionate monohydrate, C(28)H(37)BrO(7)·H(2)O, which has a 9α-Br atom in place of the 9α-Cl atom of monohydrated beclometasone dipropionate, one six-membered ring is planar (r.m.s...

Salmeterol is a selective long-acting beta 2-agonist bronchodilator considered to have added anti-inflammatory effects, but this is controversial. We investigated the effects of a single dose of salmeterol, 100 micrograms, on the physiological and inflammatory responses to inhaled allergen and compared these with the effects of a single dose of beclomethasone, 500 micrograms, and of placebo. Ei...

although response to intranasal steroid therapy has been reported in pa¬tients with allergic rhinitis, efficacy of some nasal steroids is noteworthy. this study was undertaken to evaluate the efficacy of a two-week course of fluticasone (flixonase) nasal spray vs. beclomethasone (beconase) nasal spray in patients with symptoms of allergic rhinitis referred to our clinic. this study reviewed six...

Twelve patients with chronic asthma received either high dose beclomethasone once a day or standard doses of beclomethasone three times a day in a double blind crossover trial to determine whether inhalation once a day would be sufficient. With the once a day regimen peak expiratory flow rates fell significantly, symptoms of nocturnal asthma increased, and two patients withdrew from the study b...

Allergic rhinitis causes an impairment of the mucociliary function in the nose. It is hoped that treatment of perennial allergic rhinitis would be able to revert mucociliary function to normal. This study aims to compare pre and post treatment mucociliary transport time in 3 different treatment modalities. Ninety-two newly diagnosed patients with allergic rhinitis were randomised into 3 groups ...

14 children with severe asthma were studied for 2 months in a double-blind cross-over trial to compare the efficacy of beclomethasone dipropionate delivered as an aerosol and as a powder from a rotahaler. Inhalation via the aerosol was satisfactory in 13 patients, each of whom used the rotahaler correctly. Younger children preferred to use the rotahaler. Comparison of daily symptoms, twice dail...
