The provisional suspension of fenspiride medicines is based on recent nonclinical studies (hERG channel binding and in vitro animal model studies) that showed that fenspiride has the potential to increase QT intervals in humans. This data was supportive of a previously suspected link between fenspiride and QT prolongation/ torsades de pointes in humans, which was based on a limited number of case reports.
The committee also informed patients and healthcare professionals that cough medicines containing fenspiride could cause sudden serious heart rhythm problems. It further advised them to stop using these medicines till the urgent EU safety review by authorities reaches a final conclusion. Healthcare professionals will be informed in writing about the suspension, and further information will be provided as needed and once the review has concluded.
