This invention is directed to methods for treating conditions which present with low bone mass in a patient in need thereof using continuous combination therapy with a synergistically effective combination of an EP4 receptor selective agonist or a pharmaceutically acceptable salt thereof, such as 5-(3-2S-[3R-hydroxy4-(3-trifluoromethyl-phenyl)-butyl]-5-oxo-pyrrolid in-1-yl}-propyl)-thiophene-2carboxylic acid or a pharmaceutically acceptable salt thereof; and an estrogen or a pharmaceutically effective salt thereof. The present methods are useful for treating conditions that present with low bone mass including osteoporosis, osteotomy, osteoporotic fracture, childhood idiopathic bone loss, periodontitis and low bone mass and for enhancing bone healing following facial reconstruction, maxillary reconstruction or mandibular reconstruction, inducing vertebral synostosis, enhancing long bone extension, enhancing the healing rate of a bone graft or a long bone fracture or enhancing prosthetic ingrowth in a patient in need thereof.
本发明涉及使用具有协同作用的EP4受体选择性激动剂或其药学上可接受的盐(例如5-(3-2S-[3R-羟基-4-(3-三
氟甲基苯基)-丁基]-5-
氧代
吡咯烷-1-基}-丙基)-
噻吩-2-
羧酸或其药学上可接受的盐)和
雌激素或其药学上有效的盐的连续联合疗法,用于治疗患有低骨密度的患者的疾病。本方法适用于治疗低骨密度症状,包括骨质疏松症、骨切开术、骨质疏松性骨折、儿童特发性骨质流失、牙周炎和低骨质量,以及增强面部重建、上颌重建或下颌重建后的骨愈合,诱导椎体融合,增强长骨延长,增强骨移植或长骨骨折的愈合速度或增强患者的假体生长。
