Pioglitazone is a prescription drug that is used to treat diabetes.
It belongs to a family of drugs called thiazolidinediones (or TZDs for short) which have been identified as having potential for treating Parkinson's. And we are funding a research project at the University of London that is investigating this potential - you can read more about it here:http://www.parkinsons.org.uk/PDF/G-1101_Duchen_plain_english_summary.pdf
At this stage, the researchers are looking at the effect of these type of drugs on cells grown in the lab.
And so far I don't think any results have been released from the US trials of pioglitazone in people with Parkinson's - so at this stage it's too soon to know if it will be beneficial.
If anything exciting does emerge we will let people know through our website and magazines.
I hope that this helps to answer your question.
