NCT04574713

Brief Summary

The main objective of this study is to see whether the favorable preventative effect of candesartan 16 mg per day in episodic migraine, that was found previously in two smaller randomized controlled cross-over studies, can be confirmed in a larger, multicenter, randomized controlled parallel group study. In addition it will be investigated whether 1) also a smaller dose of 8 mg is effective, and 2) whether the favorable side effect profile, seen in previous studies, can be confirmed, and whether it is even better with the smaller dose.
