Prophylactic Treatment With Atorvastatin for Chronic Migraine (ChronicStatinMig)

The main objective of this study is to see whether the favorable preventative effect of Atorvastatin 40mg per day in episodic migraine, that was found previously in three 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) the favorable side effect profile, seen in previous studies, can be confirmed, and whether it is even better with the smaller dose, and 2) estimating the cost of Atorvastatin treatment, considering cost of medicine, cost of acute attack medicine, and cost of lost worktime.
