Computational Modelling and Optimization of Dry Powder Inhalers
Dry powder inhalers (DPIs) are a common therapeutic modality for lung diseases such as asthma, but they are also used to treat systemic diseases such as diabetes. Advantages of DPIs include their portable design and low manufacturing costs. Another advantage of DPIs is their breath activation, …

In vitro methods to predict aerosol drug deposition in normal adults
… of predicting in vivo drug deposition from dry powder inhalers, DPIs, in lung-normal human adults. Three physical models of the mouth, throat and upper airways, MT-TB, were designed and validated using the anatomical literature. Small, medium and large versions were constructed to cover …

Engineering of Inhalation Aerosols Combining Theophylline and Budesonide
… disease treatment is by inhalation, such as dry powder inhalers (DPI) being the delivery systems of first choice. As shown recently, there is an advantageous effect if the drugs are given simultaneously which is caused by a synergistic effect at the same target cell in the lung epithelia. …

Investigations to identify the influence of the inhalation manoeuvre on the ex-vivo dose emission and the in-vitro aerodynamic dose emission characteristics of dry powder inhalers: Studies to identify the influence of inhalation flow, inhalation volume and the number of inhalations per dose on the ex-vivo dose emission and the in-vitro aerodynamic dose emission characteristics of dry powder inhalers.
Currently available dry powder inhalers (DPIs) for drug delivery to the lungs require turbulent energy to generate and disperse aerosol particles in the respirable range ¿5¿m during inhalation. The patient's inspiratory effort together with the resistance inside the device creates this energy. …

Use of nanoemulsion liquid chromatography (NELC) for the analysis of inhaled drugs. Investigation into the application of oil-in-water nanoemulsion as mobile phase for determination of inhaled drugs in dosage forms and in clinical samples.
There has been very little research into the bioanalytical application of Microemulsion High Performance Liquid Chromatography (MELC), a recently established technique for separating an active pharmaceutical ingredient from its related substances and for determining the quantity of active drug in a …

Performance of two different types of inhalers. Influence of flow and spacer on emitted dose and aerodynamic characterisation.
This thesis is based around examination of three mainstream inhaled drugs Formoterol, Budesonide and Beclomethasone for treatment of asthma and COPD. The areas investigated are these which have been raised in reports and studies, where there are concern, for drug use and assessment of their use. In …
