Arms Assigned Interventions
Experimental: 1 Candesartan Drug: Candesartan
Candesartan cilexitil tablets, 16 mg once daily
Active Comparator: 2 propranolol Drug: propranolol
Propranolol hydrochloride capsules 160 mg once daily, slow release formulation
Placebo Comparator: 3 Placebo Drug: placebo
placebo tablets and capsules

Detailed Description:
Candesartan was shown to be effective for migraine prophylaxis in a randomized double blind cross-over study published in 2003. The drug is now widely used for this purpose in many countries, although no confirmatory study has been published. The aims of the present study are: 1) to see if the results in the first candesartan study can be replicated in a new patient population, including patients with chronic migraine, and, 2) to perform a head-to-head comparison of candesartan 16 mg/day with standard treatment with propranolol 160 mg slow release. We also intend to study whether responsiveness to these drugs may be related to heart rate variability and baroreceptor sensitivity.
