The present invention relates to prophylactic antimigraine agents comprising as an active ingredient a dual antagonist for the 5-HT2B and 5-HT7 receptors, the antagonist having a binding affinity selective for the 5-HT2B and 5-HT7 receptors.
Since these prophylactic antimigraine agents show an excellent pharmacological effect in comparison with the cases in which a 5-HT2B receptor antagonist having a selective binding affinity to the 5-HT2B receptor or a 5-HT7 receptor antagonist having a selective binding affinity to the 5-HT7 receptor is used alone, they are useful as drugs which are excellent in prophylaxis of migraine and in which the side effects found in the existing prophylactic antimigraine agents are reduced.
本发明涉及预防性抗偏头痛制剂,其活性成分包括 5-HT2B 和 5-HT7 受体双重拮抗剂,该拮抗剂对 5-HT2B 和 5-HT7 受体具有选择性结合亲和力。
与单独使用对 5-HT2B 受体具有选择性结合亲和力的 5-HT2B 受体拮抗剂或对 5-HT7 受体具有选择性结合亲和力的 5-HT7 受体拮抗剂的情况相比,这些预防性
抗偏头痛药剂显示出卓越的药理作用,因此,它们可作为预防偏头痛的良药,并可减少现有预防性
抗偏头痛药剂的副作用。
