Patients suffering from asthma and diabetes could benefit
Patients suffering from conditions as diverse as asthma and diabetes could benefit from research at Cardiff University to improve the effectiveness of drugs taken through spray inhalers. Scientists in the Welsh School of Pharmacy are working on new nano-particle drug formulations for inhalers, and enhancers to improve the effectiveness of proteins, such as insulin, delivered to the lung.
"Drugs delivered through inhalers are usually either in a suspension (as particles dispersed in liquid), or in a solution (when the drug is dissolved in the liquid)," explained Dr James Birchall. "However, there are problems with both methods - a suspension can lead to sediment in the inhaler and less of the drug reaching the target area of the lung, while solutions present problems in dissolving the drug in the inhaler propellant liquid and can make the drug itself less stable."
