SETTING States of Haryana, Karnataka, Maharashtra and Rajasthan, and Chennai (capital of Tamil Nadu State), India. OBJECTIVE To assess the availability, price and affordability of beclomethasone and salbutamol inhalers in five Indian states using a standardised methodology. DESIGN Data on the availability and price of two essential medicines for asthma, beclomethasone (50 microg/dose) and s...

Salbutamol-induced cardiac complications are well-established. Herein, we describe a case of a 24-year female who was admitted to the emergency department because of a suicide attempt with salbutamol (76 mg). Salbutamol abuse induced the development of supraventricular tachycardia and ventricular fibrillation. Regular sinus rhythm was restored with defibrillation. The hypokalemic patient who st...

In a double-blind controlled trial 14 chronic asthmatic patients with regular nocturnal exacerbations took 16 mg slow-release oral salbutamol (two Ventolin spandets), 450 mg slow-release aminophylline (two Phyllocontin Continus tablets), or placebo at midnight. Mean peak expiratory flow rates on waking were significantly higher on the active drugs than on placebo (p < 0.01 for salbutamol; p < 0...

The bronchodilator and cardiovascular activity of isoproterenol hydrochloride (Isuprel) 5.0 mg, Salbutamol 5.0 and 2.5 mg and saline administered by IPPB to 30 patients with chronic bronchial asthma were determined and compared. Equal doses of isoproterenol and Salbutamol had similar peak bronchodilator effect, but the peak effect was reached much earlier with isoproterenoL Salbutamol bad longe...

Accelerated sinus rhythm is an important side effect of inhaled salbutamol which is especially harmful in patients with chronic obstructive pulmonary disease (COPD) and coronary heart disease (CHD). Cross-over, randomized, open label study design. 20 patients (18 males and two females) with COPD stage II-IV and comorbide CHD NYHA class I-III were included. Spirometry with 400 mg salbutamol inha...

As a worldwide ban on the use of chlorofluorocarbons (CFCs) in inhaler devices approaches, considerable attention has been focused on the production of CFC-free delivery devices. The aim of our study was to compare the delivery of salbutamol by dry powder inhaler (DPI), Turbuhaler and a CFC-free metered-dose inhaler (MDI), Airomir, used with a novel small volume metal spacer (NebuChamber). Ten ...

The aim of this study was to investigate whether the positive inotropic effects of the beta 2-adrenoceptor agonist salbutamol are increased by foreshortening of the diaphragm, and to determine the mechanism of action of these effects. Diaphragm strips were studied either at optimal resting length (Lo) or at approximately 70% Lo. In an initial experiment (Experiment I) salbutamol was added to th...

BACKGROUND On the basis of the presence of beta2-receptors within the sympathetic nervous system, beta2-stimulation may increase cardiac sympathetic outflow. We addressed the hypothesis that sympathoexcitatory beta2-receptors are present in the human left ventricle. METHODS AND RESULTS The beta2-agonist salbutamol was infused into the left coronary artery in 3 groups of patients: group 1 (n=9...

The present investigation deals with the development of controlled release tablets of salbutamol sulphate using graft copolymers (St-g-PMMA and Ast-g-PMMA) of starch and acetylated starch. Drug excipient compatibility was spectroscopically analyzed via FT-IR, which confirmed no interaction between drug and other excipients. Formulations were evaluated for physical characteristics like hardness,...

Background Acute bronchiolitis is common cause of hospitalization in infants and young children. There are widespread variations in the diagnosis and management. Despite the use of bronchodilators for decades, there is lack of consensus for the benefit of one above another. Objective To compare initial response of nebulized adrenaline and salbutamol. Method Children aged two months to two years...
