1980s - Multi action effect discovered
In the early 1980s, the collaboration with one of the most renowned pharmacologist of the time, Professor Ammon of the University of Tübingen, was initiated. In 1986, this intense preclinical research cooperation led to the discovery of a key feature of Iberogast®: its dual mode action. The different effects of the medicine on the gastrointestinal tract – relaxation on the one hand and stimulation on the other – prompted a spate of further research activities and publications. From the mid-1980s, extensive research was carried out on Iberogast® to further demonstrate also its safety. Additionally, Iberogast® started to be marketed internationally for the first time in the 1980s.
