Generation of an antidepressant - Valdoxan

Generation of an antidepressant - Valdoxan

Aberdeen research is crucial for the development of the anti-depressant drug Valdoxan

Melatonin is a hormone found in humans that conveys night and day within our bodies. Original basic research at the Rowett Institute of Nutrition and Health helped in the identification and development of melatonin compounds for the treatment of disorders of the human body-clock, so called biorhythms. Importantly these determine when we sleep and when we are awake as well as making sure that our metabolism matches these cycles.

One of these compounds was identified as having positive effects for disrupted circadian rhythms and had beneficial outcomes for patients with depression. As a result of this research a pharmaceutical company launched a brand-new anti-depressant drug called Valdoxan®. Today Valdoxan® is an award winning anti-depressant drug and is the only anti-depressant drug to be brought to the market in the last 10 years.

The research undertaken at Aberdeen as part of a strategic alliance partnership with a large pharmaceutical company was instrumental to the development of Valdoxan®, which is currently making a difference to over 3 million patients receiving treatment with this drug
