[Essential headache as an equivalent to a withdrawal syndrome: experience with naloxone]. / La cefalea essenziale come equivalente della sindrome di astinenza: esperienza col naloxone.

The Authors, starting with the hypothesis that could exist a correlation between the opiate withdrawal and the migraine crisis, used the naloxone, opiate pure antagonist, in order to induced the migraine crisis. 30 patients affected by migraine were studied; naloxone was administered acutely (2 mg e.v.) during the asintomatic period. The naloxone administration never caused the migraine crisis. The patients didn't complain variations regarding the psycho-physical status or the monitored clinical parameters.

DHE retard for prophylactic therapy of migraine: efficacy and tolerability.

The authors evaluated the efficacy of a DHE methanesulphonate for migraine attacks and its tolerability on liver, gallbladder and cardiovascular system functions. Twenty-eight patients affected by migraine were studied. They were withdrawn from preventive therapy for at least one month and treated for three months. The drug showed a good efficacy with a statistical significant reduction of severity and duration of attacks. No variation of the biochemical and morphological parameters of liver, gallbladder and cardiovascular function were found throughout the treatment.
