pridopidina

Pridopidine has a long history. The drug was initially tested by the NeuroSearch company which believed that it had an effect on dopamine as its main mechanism and was therefore able to act on movement coordination. On this assumption, starting from 2007, two studies were conducted, MermaiHD and HART, both failed.

In 2012, Teva Pharmaceuticals bought the right to test pridopidine again and promoted a third study, PRIDE-HD, which tested different doses, again with the aim of verifying the drug's effects on motor function.
