Description
本發明為有關含有奧美沙坦酯及氨氯地平之醫藥組成物。
現今,血管緊張素II(angiotensin II)受體拮抗劑及鈣通道拮抗劑作為廣泛用於治療或預防高血壓症或心疾病等之醫藥。腎酵素-血管緊張素系之抑制藥之血管緊張素II受體拮抗劑對腎酵素依存性之高血壓症特為有效,對心血管和腎臟之障礙呈示保護作用。又鈣通道拮抗劑除血管擴張作用之外,也具有鈉利尿作用,故對體液貯留性(腎酵素非依存性)之高血壓症也有效。故若併用血管緊張素II受體拮抗劑及鈣通道拮抗劑,則除由血管緊張素II受體拮抗劑之腎酵素-血管緊張素系之抑制效果之外,也具有由於鈣通道拮抗劑之於血管平滑肌中鈣通道拮抗作用及二次性鈉排泄作用,可將複數之高血壓之成因同時抑制,可期待不依病因而呈示安定且充分之高血壓症之治療或預防效果。
又噻(Thiazides)系利尿劑也作為廣泛用於治療或預防高血壓症或心疾病等之醫藥。噻系利尿劑由其利尿效果對高血壓症之治療有效。故併用血管緊張素II受體拮抗劑及噻系利尿劑,則除由血管緊張素II受體拮抗劑之腎酵素-血管緊張素系之抑制效果之外,也具有由於噻系利尿劑之利尿作用,可將複數之高血壓之成因同時抑制,可期待不依病因而呈示安定且充分之高血壓症之治療或預防效果。
已知4-(1-羥基-1-甲基乙基)-2-丙基-1-[2’-(1H-四唑-5-基)聯苯基-4-基甲基]咪唑-5-羧酸(5-甲基-2-側氧基-1,3-二茂烯-4-基)甲酯(以下稱奧美沙坦酯)為優異之血管緊張素II受體拮抗劑,可用於作為治療或預防高血壓症及心疾病等之醫藥(專利第2082519號公報、美國專利第5,616,599號公報)。

於通常使用範圍配合種種含鈣添加劑之製劑之奧美沙坦酯之溶出試驗結果如表11。與不含有鈣之製劑20比較,任何製劑皆呈示高溶出率。又如表12所示,作為參考例,於同樣配合鹼土類金屬之鎂配合製劑、偏矽酸鋁酸鎂或碳酸鎂配合製劑呈示高溶出率,但配合其他含有鎂之添加劑之製劑則為低溶出率。
含有奧美沙坦酯、氨氯地平苯磺酸鹽、氫氯噻之製劑之製造(5)
於奧美沙坦酯、氨氯地平苯磺酸鹽、氫氯噻,添加賦形劑(D-甘露糖醇(默克公司製,Parteck M100))、崩壞劑(部分α化澱粉(Colorcon公司製,Starch1500)、低取代度羥丙基纖維素(L-HPC)(信越化學工業公司製,LH-21)、交聯羧甲醚纖維素鈉(FMC Biopolymer公司製,Ac-Di-Sol)、羧甲基澱粉鈉(JRS Pharma公司製,Exprotub),於鈣添加系添加碳酸鈣後,以乳鉢混合,篩過後再度混合,加潤滑劑(硬脂酸鎂)來混合。所得混合物用Φ 9mm2重R之杵以油壓泵來成形,得製劑32至製劑39(表13)之錠劑。
含有奧美沙坦酯、氨氯地平苯磺酸鹽、氫氯噻之製劑之溶出試驗(5)
仿(試驗例1)之方法實施試驗。
製劑32~製劑39中奧美沙坦酯之溶出試驗結果如表14。如表14所示,添加同一崩壞劑之系中,配合含鈣之添加劑之製劑,比不含有含鈣添加劑之製劑呈示高奧美沙坦酯之溶出率。
試驗為就3錠施行,以其平均值表示。
依本發明可得以含有(A)奧美沙坦酯及(B)氨氯地平為有效成分,且含有(C)含鈣添加劑為特徵之改善溶出性之之醫藥組成物。
