چکیده

The effect of a new breath actuated dry powder inhaler, the Turbuhaler, was found to be reduced at inhalations slower than 28 1/minute. This flow rate could be generated by virtually all children aged greater than or equal to 6 years, by 42 of 57 children less than 6 years (74%), and by six of 15 preschool children with acute wheeze (40%).

Peak inspiratory flow through Turbuhaler in acute asthma.

Efficient use of dry powder inhalers, such as Turbuhaler, is dependent on the generation of adequate inspiratory flow. It is not clear whether patients with acute asthma are able to generate adequate flow. Peak inspiratory flow (PIF) was measured through an empty Turbuhaler, and without this device, in 99 adults presenting to hospital with acute exacerbations of asthma. Where possible, patients...

Lung deposition from the Turbuhaler in children with cystic fibrosis.

Drug delivery to patients using dry powder inhalers, such as the Turbuhaler, is believed to be influenced by the inspiratory flow used. Clinical studies have indicated that this delivery system can be used effectively by children. However, it is not known how the total and weight-corrected dose delivered to the airways varies with age. A deposition study using technetium-99m (99mTc)-labelled bu...

Lung deposition of budesonide inhaled via Turbuhaler: a comparison with terbutaline sulphate in normal subjects.

We wanted to evaluate whether lung deposition of budesonide and terbutaline sulphate differs, and to determine lung deposition of budesonide inhaled at different peak inspiratory flows, through Turbuhaler. Lung deposition of budesonide, a lipophilic substance, and of terbutaline sulphate, a hydrophilic substance, was therefore compared, after administration via an inspiratory flow-driven, multi...

The impact of inspiratory effort on inspiratory flow through Turbuhaler in asthmatic patients.

To investigate the impact of the inhalation effort on the peak inspiratory flow through Turbuhaler, 100 asthmatics having a wide range of asthma severity (baseline forced expiratory volume in one second 28-127% of predicted normal) were studied. Each patient inhaled through four modifications of empty Turbuhaler inhalers, using first a "deep" inhalation and then a "forceful and deep" inhalation...
