1.Bronchial spasmolytic action of terbutaline and fenoterol compared with that of ipratropium bromide in the anaesthetized dog.
Stepanek J Arch Int Pharmacodyn Ther. 1978 Aug;234(2):308-28.
Continuous recordings of heart rate, respiration rate, minute volume and bronchial resistance were made over a period of altogether three hours in spontaneously breathing dogs anaesthetized with chloralose. At hourly intervals, before and 1 and 2 hr after the administration of bronchodilators, bronchial spasm was induced by inhalation of an acetylcholine solution. Two beta2-stimulants, terbutaline and fenoterol, were administered by inhalation in doses of 0.5, 0.16 and 0.05 mg/kg and 0.1, 0.3 and 0.01 mg/kg respectively. For comparison, an atropine derivative, ipratropium bromide, was also given by the same route in doses of 0.04 and 0.01 mg/kg. Controls received normal saline. Terbutaline and fenoterol caused an increase in heart rate, respiration rate and minute volume. Acetylcholine-induced bronchial spasm was inhibited to the extent of 10--70% for 2 hr after the administration of terbutaline, and by 15--70% after fenoterol. The acetylcholine antagonist ipratropium bromide caused only transient changes in heart rate, respiration rate and minute volume. Acetylcholine-induced bronchial spasm was inhibited by 95% and 80% for 2 hr after doses of 0.04 and 0.01 mg/kg, respectively. Fenoterol had a slightly greater central stimulant effect than terbutaline; ipratropium bromide displayed no stimulant activity.
2.[Efficiency of nebulised magnesium sulphate in infective exacerbations of chronic obstructive pulmonary disease].
Cömert Ş;Kıyan E;Okumuş G;Arseven O;Ece T;İşsever H Tuberk Toraks. 2016 Mar;64(1):17-26.
INTRODUCTION: ;Conflicting results has been achieved in a small number of clinical studies evaluating the efficiency of magnesium sulphate (MS) in COPD exacerbations. We aimed to investigate the efficiency of nebulised MS in COPD exacerbations.;PATIENTS AND METHODS: ;Twenty patients who met the study criteria were randomized into two groups. All patients were treated with O2, antibiotics and oral corticosteroids. Additionally one group received ipratropium bromide (IB) 500 µg together with MS 151 mg/dose, while the other group received IB together with placebo. The patients were followed-up with forced expiratory volume in 1 second (FEV1) and visual analogue scale dyspnea scores for 48 hours. Peak expiratory flow rates (PEFRs) were measured before and 10, 30, 60 and 120 minutes after each nebule treatment.;RESULT: ;The baseline characteristics of the patients in both groups were similar. The FEV1 values measured at 24 and 48 hours did not show significant changes compared to baseline in both groups. Dyspnea scores in both groups decreased significantly in the first day, and in only MS group in the second day. The % change in the dyspnea score at the end of first day was significantly more in the MS group [-23.
3.A pilot study comparing the antispasmodic effects of inhaled salmeterol, salbutamol and ipratropium bromide using different aerosol devices on muscarinic bronchoconstriction in healthy cats.
Leemans J;Kirschvink N;Bernaerts F;Clercx C;Cambier C;Gustin P Vet J. 2009 May;180(2):236-45. doi: 10.1016/j.tvjl.2007.11.008. Epub 2008 Feb 21.
This study compared the duration and magnitude of the antispasmodic effects of salmeterol (SLM), salbutamol (SAL), ipratropium bromide (IB) and the combination of SAL and IB (SAL/IB) against carbachol-induced bronchoconstriction in healthy cats, and investigated the gain in efficacy using a two or fourfold increase in drug dosages. The drug regimens used were: (1) SLM 25 microg, SAL 100 microg, IB 20 microg and SAL/IB 100 microg/20 microg for bronchodilators delivered by a metered-dose inhaler (MDI); (2) SAL 3.75 mg and IB 62.5 microg for nebulised (NEB) medications. To monitor the bronchodilator effect, airway responsiveness was assessed at different time points using barometric whole-body plethysmography and calculation of the concentration of inhaled carbachol inducing a 300% increase of baseline Penh (enhanced pause), an estimator of airflow limitation. Maximum C-Penh300 was recorded 15 min after NEB SAL, IB MDI, NEB IB and 1h after SAL MDI and 4h after SLM MDI, respectively. C-Penh300 was significantly different from control values (without treatment) up to 24h for SLM MDI, 8h for IB MDI and 4h for other drugs. In terms of efficacy, SAL/IB MDI showed a synergistic antispasmodic effect at 15 min, 4h and 8h after administration.
