Nano-particle research will benefit inhaler-users

02.05.2005


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."


The Cardiff team’s approach is to prepare the drug in nano-particle form – ensuring the correct dosage reaches the lung and the drug retains its stability, and providing the possibility of slowing the release of the drug in the lung for longer therapeutic effect.

This could lead to the possibility of more drugs being administered effectively by inhaler, rather than by tablet or injection.

Meanwhile, the team is also developing a process which uses a naturally occurring substance to enhance the absorption of insulin. Initial studies suggest insulin is absorbed three to four times more effectively by this process.

Now Dr Birchall and his colleague Dr Glyn Taylor of The Pulmonary Research Group aim to combine the two innovations to prolong and maximise the absorption effect.

"These two technologies could make a huge improvement in the effectiveness of spray inhalers for users suffering from a wide range of illnesses and conditions," said Dr Birchall.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
