(1) (1)200408387 玖、發明說明 【發明所屬之技術領域】 本發明係關於一種藥物,特別是治療膀胱過動症之藥 物。 【先前技術】 下尿道官能障礙乃廣泛地分類成積尿病症(頻尿和尿 失禁),以及排尿病症(解尿困難和無尿症)。尿失禁係積 尿病症的典型實例,並且定義爲主觀上可證明之尿滲漏, 因此在普通日常生活及衛生上皆會發生困難。頻尿係一超 出正常排尿頻率的狀態,並且定義爲夜間約2次或更多以 及24小時期間9次或更多。尿失禁可分類爲腹壓性尿失禁 ,其係在有腹壓時如咳嗽或打噴嚏期間即會發生;迫近性 尿失禁,其係在病患到達洗手間前就突然發生尿滲漏;以 及腹壓性尿失禁與迫近性尿失禁的混合型尿失禁(Current Therapy, 19(12)期,8-11頁,200 1 年)° 當缺少可說明這些徵狀的局部病理學、經神學或代謝 之因素時,膀胱過動症只是一種帶有或不帶有急迫性尿失 禁之相關於頻率與急迫徵狀的醫學狀態(Urology,55期(補 增版5A),1-2頁,2000年)。更特定言之,下列3個族群可 涵蓋在膀胱過動症中:(1)只是單獨地頻尿及急尿,(2)頻 尿、急尿和迫近性尿失禁,以及(3)混合型尿失禁。 治療膀胱過動症之藥物包括蕈毒鹼受體拮抗劑,其可 減低膀胱逼尿肌之收縮。覃毒鹼受體乃豐富地存在於膀胱 -5- (2) (2)200408387 逼尿肌中,並可經由刺激膀胱逼尿肌而引發收縮。 除了蕈毒鹼受體拮抗劑之外,目前有關之新作用機轉 的硏究也已在進行中,其包括k管道促動劑、受體興 奮劑、抑制中樞排尿反應之藥物、及前列腺素合成抑制劑 (Medicine and Drug Journal, 38^(S-1) » 2 83 -2 8 8 頁,2 0 0 2 年)。 α!受體豐富地存在於膀胱底部、尿道、前列腺、及 前列腺之上皮膜,其可刺激平滑肌而引起收縮,藉此增加 尿道阻力。因此,可減少尿道阻力之α !受體阻斷劑在治 療排尿病症上被認爲有其效用。再者,可增加尿道阻力之 α !受體興奮劑在治療積尿病症上則有其效果。舉例之, WO96/3 8 1 43案號已揭示了 α 1Α受體選擇性興奮劑可有效 地治療尿失禁,而事實上係因α1Α受體牽涉到尿道及膀胱 頸之收縮。W〇99/5 7 1 3 1案號也已揭示a 1D受體阻斷劑可 有效地治療膀胱及下尿道病症所發現之刺激徵狀,而事實 上係因a1D受體局部地存在於膀胱中。 目前,治療膀胱過動症之新穎藥物已可搶先問世。 【發明內容】 在這些情況下,本發明人頃發現到坦洛新 (tamsulosin)或其鹽類可有效治療膀胱過動症。 更特別地,本發明係關於一種用以治療膀胱過動症之 藥物,其中含有坦洛新或彼之藥理學上可接受之鹽做爲有 效成份。 -6- (3) 200408387 本發明進一步係關於利用坦洛新或彼之藥學上可接受 鹽以製造膀胱過動症之治療劑。再者,本發明係關於一種 供治療膀胱過動症之方法,其中該方法包括將坦洛新或彼 之藥學上可接受鹽投藥予病患。 坦洛新之化學名稱係(R) (-)-5-[2-[[2-(鄰-乙氧基苯氧 基)乙基]胺基]丙基]-2-甲氧基苯-磺醯胺,並可以下列結 構式表示。坦洛新最先是與其藥學上可接受鹽一起揭示於 曰本專利特許公開申請案Sho- 5 6/ 1 1 0665案號中。

CH—c—NHCH2CH2〇 H2N〇2-S H o.ch2ch3 眾所知悉地,坦洛新及其鹽類可展現腎上腺素a i A受 體阻斷作用,特別地,其氫氯酸鹽(坦洛新氫氯酸鹽)可作 用來阻斷尿道及前列腺之α !受體,因此可藉由減低尿道 壓力輪廓之前列腺壓力部分,而廣泛地用做爲改善與前列 腺肥大有關之排尿病症的藥物。近年來,這些物質也已證 明可有效地治療和神經性膀胱及下尿道病症相關之排尿病 症(此排尿病症係和下尿道功能閉鎖有關聯,而與完全性 器官病症或下尿道神經學上之反常無關聯)(WO 00/00 1 87 案號,WO 0 1 / 1 043 6案號)。 目前,尙未有任何報告可確定積尿病症(頻尿、尿失 禁)之功效。然而,本發明人是第一個確認坦洛新氫氯酸 (4) (4)200408387 鹽在治療膀胱過動症上的臨床功效。 再者,本發明係關於用以治療膀胱過動症之藥物,其 中含有坦洛新或彼之藥理學上可接受之鹽及覃毒鹼受體拮 抗劑或彼之藥理學上可接受之鹽做爲有效成份。由於不同 的作用機轉,可預期地,坦洛新(α !受體阻斷劑)與覃毒 鹼受體拮抗劑能提供協乘性效果。 本發明進一步係關於利用坦洛新或彼之藥學上可接受 鹽以製造可與蕈毒鹼受體拮抗劑結合之藥劑而用於治療膀 胱過動症。而且,本發明也係關於一種供治療膀胱過動症 之方法,其中該方法包括將坦洛新或彼之藥學上可接受鹽 與蕈毒鹼受體拮抗劑組合而投藥予病患。 本發明將更加詳細地解說如下: 膀胱過動症治療藥物係一種可用以治療膀胱過動症或 改善膀胱過動症之徵狀的藥物。在本發明中,”膀胱過動 症”一詞是表示,在缺少可說明這些徵狀的局部病理學、 經神學或代謝之因素時,帶有或不帶有急迫性尿失禁之相 關於頻率與急迫徵狀的醫學狀態。膀胱過動症之患者不僅 包括成人,也涵蓋小孩。 坦洛新及彼之藥學上可接受鹽可藉由日本專利特許公 開申請案Sho-56/1 1 0665案號及Sho-56/ 1 1 4952案號中所揭 示之方法或其類似之方法而輕易製得。 ί旦洛新也可與寬廣範圍之無機或有機的酸和鹼形成藥 學上可接受之酸及鹼-加成鹽。此類鹽也可構成本發明之 一部份。彼等之實例是與無機酸如氫氯酸、硫酸、磷酸之 -8- (5) (5)200408387 鹽類;與有機酸如富馬酸、蘋果酸、檸檬酸、琥珀酸之鹽 類;與鹼金屬如鈉、鉀之鹽類;以及與鹼土金屬如鈣、鎂 等之鹽類。在本發明中,以氫氯酸鹽爲最佳。此類鹽可依 習知之方法製造。 本發明之藥學製劑可依習知之方法藉由使用有機或無 機載劑、塡充劑及其他適於口服或非經腸方式投藥之添加 劑而製備成口服固體製劑、口服液體製劑、注射用製劑。 較佳地是口服固體製劑,因其可輕易地由病患自己投服, 並可方便保存與攜帶,更特定言之,彼等可爲藥錠、稀釋 之散劑、顆粒、細粒、膠囊、藥九,等。 在此類固體製劑中,活性物質將與至少一個惰性稀釋 劑如,乳糖、甘露糖醇、葡萄糖、微晶纖維素、澱粉、聚 乙烯吡咯烷酮或矽酸鎂與鋁酸鎂混合。根據習知之方法, 此組成物可包含非惰性稀釋劑之添加劑,而這些添加劑的 實例有黏合劑如羥丙基纖維素及羥丙基甲基纖維素;潤滑 劑如硬脂酸鎂、硬脂酸鈣、聚乙二醇、澱粉及滑石;崩解 劑如纖維素乙醇酸鈣;安定劑如乳糖;溶解輔助劑如麥氨 酸及天門冬氨酸;增塑劑如Tween 80及三醋酸甘油酯; 以及著色劑如二氧化鈦及倍半氧化鐵。若需要時,也可用 糖衣包覆藥錠或藥九,或者用一經胃或腸方式之物質如蔗 糖、明膠、瓊脂、果膠、羥丙基纖維素及羥丙基甲基纖維 素的薄膜來包覆。 本發明中最佳製劑是持續釋放形態之持續釋放型製劑 。該持續釋放型製劑可藉由已知之方法製成藥錠、顆粒、 -9- (6) (6)200408387 細粒或膠囊。舉例說明之,該持續釋放型製劑可藉由已知 方法用脂/油' 聚丙三醇之脂肪酸酯、羥丙基纖維素等包 覆藥錠、顆粒、細粒或膠囊而製備。 曰本專利特許公開申請案Sh〇-62/9案號所揭示之持續 釋放型製劑是較佳的。因此,在每一單位製劑中,那些將 洗提抑制劑加入於活性化合物之混合物後再經由製粒過程 而製得,且在每一單位中具有不小於5 0重量%之劑量形成 物質的粒子係藉由習知之方法塡入於膠囊內,以製備成膠 囊製劑或藥錠。關於洗提抑制劑,可使用不溶於水之高分 子物質如丙烯酸系聚合物、共聚物或纖維素衍生物,較適 當的是水性懸浮液、水性乳化液或溶於含水之有機溶劑的 溶液等形態的洗提抑制劑。其商品化實例有Eudragit L30D55 (甲基丙烯酸共聚物LD)、Eudragit E 30D (丙烯酸 乙酯與甲基丙烯酸甲酯之共聚物乳化液)及A quae oat ECD-3 0 (乙基纖維素之水性懸浮液)。彼等本身即用做爲洗提抑 制劑,或者,若需要時,用水稀釋後便可使用。 在本發明目的中,最佳的是具有延長作用之經口服方 式持續釋放型製劑,其以口服方式投藥後並在上消化道及 下消化道內經由有利的藥物釋出,便能釋放某一有效成份 達12-24小時的延長時間。 舉例之,WO94/064 1 4案號所揭示之具延長作用的經 口服方式持續釋放型製劑,縱使在低水含量的結腸中也能 釋放有效成份,此乃因爲製劑留在上消化道之時就能將水 含量良好地吸收在裡面,並以幾乎完全膠質化形式往下行 -10· (7) (7)200408387 進至下消化道。更特定而言,此係一具有膠質化速率達 7 0 %或更高但小於於1 〇 〇 %之水凝膠持續釋放型製劑形態的 藥錠,其係藉由混合下列物質而製得:(1)藥物、(2)可使 水以5 - 8 0重量%範圍或更高(相對於製劑)之量侵入製劑內 的添加劑(總體而言,在溶解度上係以不大於5毫升的水溶 解1公克製劑)’以及(3)每藥錠重70毫克或更高之高分子 量物質(總體上可形成1 0 _ 9 5重量%,相對於製劑之水凝膠 ’其平均分子量爲2,000,000或更大,或者在25t下於1% 水溶液中之黏度是小於1 〇 〇 〇 c p S )。可使水侵入製劑內之添 加劑包括聚乙二醇、聚乙烯基吡咯烷酮、D-山梨糖醇、木 糖醇、精製糖、無水麥芽糖、D-果糖、葡聚糖、葡萄糖、 聚氧化乙二醇與聚氧化丙二醇、氯化鈉、氯化鎂、檸檬酸 、酒石酸、甘氨酸、丙氨酸、賴氨酸氫氯酸鹽、以及 甲葡胺。形成水凝膠之高分子物質包括聚氧化乙烯、羥丙 基甲基纖維素、羧基甲基纖維素鈉、羥乙基纖維素及羧基 乙儲基聚合物。再者,如國際公告申請案WO 01/10466案 號所揭示般,若是使用聚氧化乙烯做爲形成水凝膠之高分 子物質時’則需混合倍半氧化黃鐵及/或倍半氧化紅鐵以 防止坦洛新之持續釋放特性的改變,縱使在輻射下儲存亦 妖〇 j \\\ 坦洛新或彼之藥學上可接受鹽的劑量需因每一病況而 適當地決定’其須考慮到投藥路徑、疾病徵狀、欲治療目 標之年齡及性別等。在口服方式投藥的情況中,坦洛新氯 酸鹽通常係以約0.1至2.0毫克/每日,最佳地0.2至1.5毫克/ • 11 - (8) (8)200408387 每曰之劑量投藥予成人,且是在餐後每日一次經口投服。 本發明之藥物對單一治療而言十分有效用,同時也可 與具有不同作用機轉之覃毒鹼拮抗劑一起使用,或隔開使 用。蕈毒鹼受體拮抗劑包括有頻尿寧錠(oxybutynin)、得 舒妥膜衣銳(tolterodine)、達非那辛(darifenacin)、紐賓利 平(nubenzipin)、查米芬那辛(zamiphenacine)、替托溴銨 (tiotripium)、阿鞭莫寧(albamerin)、曲司氯銨(trospium) 、發索替洛寧(phesoterozine)、替米維林(temiverine)、3-喹寧環基-1-苯基-1,2,3,4-四氫基異D奎啉-2-甲酸酯(莎利芬 那辛(soriphenacine)、4-(2 -甲基-1H -咪卩坐-1-基)2,2-二苯基 丁基醯胺、N-[l-(6-胺基吡啶-2-基甲基)呱啶-4-基]_2(R)-[3, 3-二氟基-1(R)-環戊基]-2-羥基·2-苯基乙醯胺及其鹽類 。較佳的是M3受體選擇性拮抗劑,且更佳的是3 -喹寧環 基 1-苯基-1,2,3,4-四氫基異喹啉-2-甲酸酯(莎利芬那辛或 其鹽類。 【實施方式】 實施本發明之最佳方式 頃刻,本發明將藉由下列實施例及試驗實施例而更加 詳細地解說,但本發明並不受限於這些實施例。 實施例1 將5公克坦洛新氫氯酸鹽及470公克微晶纖維素混合好 ,並加入5 00公克之83.3公克Eudragit L30D-55(固形份爲 -12- 200408387
