The present invention relates to an agent for the treatment and/or prevention of pollakiuria comprising a compound having an antagonism to an EP
1
receptor which is a prostaglandin E
2
receptor subtype. A compound having an antagonism to an EP
1
receptor antagonistically acts on an EP
1
receptor which is a prostaglandin PGE
2
receptor subtype and significantly shows a suppressive activity for urination frequency in models where pollakiuria is induced. Therefore, it is effective for the treatment and/or prevention of pollakiuria (that which is due to nurogenic bladder, nervous bladder, stimulated bladder, unstable bladder, benign prostatic hypertrophy, etc.).
本发明涉及一种用于治疗和/或预防花粉尿症的制剂,该制剂包含一种具有拮抗 EP
1
受体(
前列腺素 E
2
受体亚型的拮抗剂。具有拮抗 EP
1
受体具有拮抗作用的化合物可拮抗 EP
1
受体上起拮抗作用,该受体是
前列腺素 PGE
2
受体亚型的 EP 1 受体上,并在诱导花粉尿的模型中明显显示出抑制排尿次数的活性。因此,它对治疗和/或预防花粉尿(由神经性膀胱、神经性膀胱、刺激性膀胱、不稳定膀胱、良性前列腺肥大等引起的花粉尿)有效。
