替米沙坦係以游離酸型式製造及供應。其特徵在於其於 胃與腸道之生理的pH範圍在pH丨至7間之水性系統中有非 常差之溶解度。如揭露於W〇 00/43370中,晶體替米沙坦 存在於二種同質多晶型體型式具有不同之熔點。在熱與溼 度之影響下,較低熔點之同質多晶型體B不可逆地轉化成 高炫點同質多晶型體A » 安脈狄平骨先揭露於EP-A-89167中。其屬於鈣離子管道 阻斷劑之群及其化學學名為3_乙基_5_甲基-2-(2-胺基乙氧 104960.doc 1355268 基甲基)-4-(2-氯苯基)-1,4 -二氫-6-曱基-3,5-°比咬二曱酸, C20H25ClN2O5,Mr 408,88,具有下列結構:
醫藥上安脈狄平視為馬來酸鹽(C24H29CIN2O9; Mr 524 , 苯續酸鹽(benzensulfonate 或 besylate)(C26H31ClN2〇8S ; Mr 567,10 ; EP-A-244944)及甲續酸鹽(C2iH26C1N2〇8S; Mr 502,01)使用。 ”鈣離子通道阻斷劑"亦稱為"鈣離子拮抗劑"或”弼離子阻 斷劑"。其為降低心臟跳動強度及放鬆血管之藥物。其用 以治療高血壓、心絞痛(胸疼痛或由減少血液供應至心臟 肌肉引起之不舒服)及某些心律不整。 φ 【發明内容】 在治療高血壓特別是病患之目標血壓無法僅以單一藥劑 達成時替米沙坦及安脈狄平之作用機制視為良好配合。對 於包含活性成份替米沙坦及安脈狄平之固^劑量組成產品 有漸牦之而求。然而,替米沙坦及安脈狄平二者皆為困難 處理之化學化合物。因此’ 藥理性功效之特徵、足夠之 方法必須克服許多技術問題 。因此’口服固定劑量組成劑型其組合 、足夠之藥穩定性及可信賴製造之強烈 定劑量組成劑型。 問題。本發明之目的為提供此種固 104960.doc °〜像有户種固定劑量組成劑型但不能預測其中那些劑 且。最佳產品穩定性、藥理性功效及可信賴製造。通 種活1±醫藥成分能規劃為口服固體或口服液體劑型 彳錠劑膠囊、膜衣或糖膜衣鍊劑、粒齊】、口服溶液' 等劑或恝浮液、糖漿及喉片齊】。鑒於對替米沙坦口服液體 7里之驗不應視為本發明較佳之具體實施例。包含二種 藥劑之立即釋放口服固體劑型能經由製成粉狀混合物或二 鲁種活形成分與必需之賦形劑共同粉化。然而,對於替米沙 t及安脈狄平之組合,此種方法無法產生具有;I夠產品穩 定ί生之劑型。具有可接受活體内成效之替米沙坦調配物必 需包含基本成份類似例如氣氧化納或葡甲錄,其中令人驚 譯的當安脈狄平與用於替米沙坦調配物中之賦形劑直接接 =時不夠穩定。在安脈狄平分子中之g旨鍵當曝露在驗性環 坆中似乎易文水解。因此,直接與必需賦形劑混合之標準 ^不能應用在固定劑型組成之㈣沙坦與安脈狄平及需 _較複雜技術分離基本替米沙坦調配物與安脈狄平藥劑物 質。在這些狀況下,膠囊(per】onget)、膜衣或雙層科技不 能使用。 膠囊(perlonget)方法係產生替米沙坦與安脈狄平之分開 :膜衣鍵,使其大小及形狀成可填入膠囊卜其對於高劑 量組合物則需要如0號或更大之大型膠囊,其對於病患之 .配合度較不隹。 狄 另一方法為應用薄膜膜衣於安脈狄平藥劑物質或含安脈 平之粒劑/丸劑上。令人驚訝地如此包衣之粒子在鹼性 W4960.doc 1355268 與吸溼氣環境之替米沙坦調配物下為不穩定。 本發明認為,結合足夠之藥劑穩定性、兩種活性成份之 最佳藥劑釋放、藥理成效及對替米沙坦與安脈狄平最佳的 可信賴製造方法之劑型,為雙層錠劑。
