Description
本發明係關於一種抑制幽門螺旋桿菌之藥物與製造方法,尤其係關於一種根除幽門螺旋桿菌之發泡錠劑型、懸浮劑型或粉劑劑型的醫藥組成物及其製造方法。
幽門螺旋桿菌(Helicobacter pylori
,以下簡稱H. pylori
)係為微嗜氧性之格蘭氏陰性(Gram-negative)桿菌,主要生存在人類或其他動物胃部的黏膜表層,即胃上皮細胞與胃黏液層(gastric mucus layer)之間。H. pylori
的感染十分普遍,世界上大約有一半以上的人曾被H. pylori
感染。研究指出H. pylori
的持續感染會造成上消化道之病變,目前已知此菌的感染有可能會引發慢性之活動性胃炎(chronic active gastritis)、消化性潰瘍(peptic ulcer)、非潰瘍性消化不良症(non-ulcer dyspepsia)、胃及食道回流疾病(GERD)、胃潰瘍(gastric ulcer)與十二指腸潰瘍(duodenal ulcer)等疾病,並和胃癌(gastric carcinoma)、胃腺癌(gastric adenocarcinoma)以及胃黏膜相關組織淋巴瘤(maltoma)的產生有相當密切的關係,因此H. pylori
被認定為可能致癌(carcinogen)的細菌。
此外,研究顯示感染H. pylori
後,若未能有效根除H. pylori
,不但會造成各類胃腸道潰瘍的反覆發作,更可能顯著增加日後罹患胃癌的發生率,舉例而言,受H. pylori
感染之消化性潰瘍,若無根除該菌體,則停藥後的復發率高達60%-95%,而根除H. pylori
則潰瘍復發率可降至20%以下。因此,H. pylori
的根除與否係為前述該些上消化道病症之治療及預後狀況之關鍵因素,且臨床上對於確定感染H. pylori
之患者,皆須施予根除式療法。然而人體受H. pylori
感染後的帶菌狀態為終生性,除非給予適當之治療,否則很少有機會可自動清除該菌。
目前H. pylori
之有效根除治療方式主要係採用二種抗生素加上一種氫質子阻斷劑(H2
Blocker)或質子幫浦阻斷劑(proton pump inhibitor,PPI)等制酸劑之三合一療法,其中抗生素種類包括青黴素類抗生素例如安莫西林(amoxicillin)、甲硝唑(metronidazole)、巨環類(macrolides)抗生素例如克利索黴素(clarithromycin)以及四環黴素(tetracycline)等四種。制酸劑如氫質子阻斷劑(H2
Blocker)或質子幫浦阻斷劑(PPI),前者則是提高胃部酸鹼值(intragastric pH value);而後者可有效抑制胃酸分泌。由於抗生素例如克利索黴素於弱酸性至鹼性環境中較安定,因此該抗生素於服用後易受到人體胃酸的破壞,而降低其根除H. pylori
之效果,因此制酸劑的添加有助於提升胃部酸鹼值(pH值),整個療程需持續7天或10-14天。若患者可配合醫師囑咐在治療期間將所有的治療用藥都按時服用完畢,則約可達八成以上之根除療效。
研究發現雖三合一療法具有根除H. pylori
之效果,然而臨床施予該療法而成功根除H. pylori
之實際比例並不如預期,推究其可能原因包含:1.病人服藥的順從性差,以目前國內臨床的三合一治療為例,第一種治療方式為每一次需服用5顆藥,包含一顆20mg之奧美拉唑、二顆500mg之安莫西林以及二顆250mg之克利索黴素,依此劑量須於早、晚各服用一次,連續服用七至十四天;另外,尚有第二種治療方式為服用三合一藥物包裝,亦需一天服用三次,並且於早晚再額外服用一顆20mg之奧美拉唑。此兩種治療方式之缺點皆為服藥顆數太多、易混淆需服用藥量或藥品種類、攜帶不易及吞嚥困難等問題,且進行第二種療法之病患常會發生忘記再加服奧美拉唑之狀況,造成無法按時定量服藥,而導致服藥順從性不佳;2.整個治療期間的藥物劑量不夠,此亦係因無依照囑咐定量服藥所致;3.藥物於胃中穩定性不佳等,導致藥物的吸收不佳無法達到治療效果;4.病人特異體質與過敏反應導致提前停藥;以及5.H. pylori
對藥物具有抗藥性,三合一療法所用抗生素甲硝唑對用藥失敗的患者均很容易產生次發抗藥性,因此該藥物使用時需注意其劑量,療程及病人配合度的問題。此外,美國專利第5,196,205號揭示一種治療H. pylori
所引發胃炎及胃十二指腸潰瘍等消化系統疾病的方法,其係施予鉍化合物(bismuth)、青黴素類與四環黴素類抗生素,且一天給予三種片劑(每一有效成分一種)數次,此種治療方式複雜。
另一方面,制酸劑例如奧美拉唑之安定性會隨其存在環境之pH值而改變,當其存在於鹼性環境下,可維持安定性,於酸性環境下,則會迅速分解,因此奧美拉唑於胃液中無法安定存在,極易被分解,因此一般會以包覆腸衣型式給予,讓奧美拉唑在腸道被吸收,經由體內循環系統抑制胃腺細胞分泌胃酸,故若使奧美拉唑直接於胃部之胃酸環境中作用,奧美拉唑便無法有效抑制胃酸分泌,導致抗生素仍於胃部酸性環境中作用,而降低抗生素根除H. pylori
的成效。
美國專利第6,350,468號提及一種雙層膠囊藥物劑型,將內膠囊放置在外膠囊內,其中,外膠囊含有次枸橼酸鉍(bismuth subcitrate)和甲硝唑,內膠囊含有四環黴素和奧美拉唑,藉以使這些有效成分在適當時間間隔下發揮作用,而根除幽門螺桿菌。美國專利第6,977,086號提及一種與現有製劑相比較具有較小重量的複合製劑,其包含安莫西林與克拉維酸鉀(potassium clavnlanate),並可製成片劑、膠囊以及粉劑等形式,藉以用於治療細菌感染。美國專利公開第20040185092號提及一種硬或軟膠囊之口服藥學劑型,含有克利索黴素或其鹽類、或含有開羅理黴素或其鹽類與奧美拉唑或其鹽類,此藥學劑型不易被胃酸破壞,且易於在中性至鹼性之溶液中溶解。
綜上所述,由於目前用以根除H. pylori
之藥物有前列缺點,若能開發一可增進病患服藥順從性例如使用便利且使老人與幼童等吞嚥困難者可輕鬆服藥,並能根除H. pylori
之藥物,將有助益於因感染H. pylori
所致上消化道疾病及癌症的治療與預防。

由於一般懸浮劑型藥物於服用時,需加特定水量使粉末顆粒溶解成懸浮液,再分次依所需劑量服用,尚未服用之懸浮液再置於4℃下儲存,數日內將其服完。為確認本發明用於根除H. pylori
之懸浮劑型醫藥組成物的儲存安定性,試驗設計為將2.024克之法莫替丁/安莫西林/克利索黴素懸浮劑加入20ml的水均勻混合後,置於4℃下避光儲存八天,並於儲存期間分別檢測法莫替丁、安莫西林以及克利索黴素之安定性。其結果如第一圖至第三圖所示。
請同時參閱第一圖至第三圖,該些圖係分別為法莫替丁、安莫西林以及克利索黴素之安定性測試結果。由該些圖示結果可知,法莫替丁、安莫西林以及克利索黴素於儲存第一天與第八天之濃度皆無顯著差異,此顯示法莫替丁、安莫西林以及克利索黴素於八天儲存期間之安定性佳。亦即利用本發明實施例懸浮劑型醫藥組成物之製程中所加入的藥學上可接受之載體,提供隔離作用,藉以使乙內醯胺類抗生素、巨環類抗生素與氫質子阻斷劑各成份於混合後不會直接相互接觸,確實可達到使此懸浮劑型醫藥組成物所含各成分安定存在之目的。
此試驗係分析發泡錠劑型醫藥組成物進入動物體內後,此藥物於動物體之血中濃度,此可表示要物之生體可用率。測試動物選用年齡為1~3歲、體重為10~12公斤之米格魯(beagle)動物狗。
將含有500mg之安莫西林(Amoxicillin)、250mg之克利索黴素(Claritharmycin)與20mg之奧美拉唑(Omeprazole)的發泡錠劑型醫藥組成物置於15mL水中發泡後餵食該動物狗,另外分別取市售含500mg之安莫西林(Amoxicillin)的膠囊(capsule)、含20mg之奧美拉唑(Omeprazole)的膠囊(capsule)以及含250mg之克利索黴素(Claritharmycin)的藥錠進行餵食,此作為對照組。於餵食後第0、0.33、0.66、1、1.5、2、2.5、3、4、6、8、10以及24小時抽血並檢測該些藥物濃度。結果如第四圖至第六圖所示。
請同時參閱第四圖至第六圖,該些圖係分別為安莫西林、克利索黴素、奧美拉唑之動物狗血中濃度測試結果。由該些圖示結果可知,相較於分別服用安莫西林膠囊、奧美拉唑膠囊以及克利索黴素(Claritharmycin)藥錠之對照組於動物狗血中的釋放濃度,本發明之包含有安莫西林/克利索黴素/奧美拉唑之發泡錠劑型醫藥組成物係可達到相等或更優於市售膠囊與藥錠的生體可用率,此表示本發明發泡錠劑型醫藥組成物所含鹼性物質例如碳酸鹽類的添加,可直接將胃內pH值調高為較鹼性環境,避免抗生素或質子幫浦阻斷劑因於強酸環境下不安定而降解,使藥物於胃部發揮作用,進而提高藥物於體內之生體可用率。
本發明用於根除H. pylori
之發泡錠劑型、懸浮劑型與粉劑劑型醫藥組成物係利用簡便之製程方法便可達到與目前市售膠囊與藥錠相同或更佳之生體相等性,且藥物安定性佳,其優點係具有崩散及吸收快速、以液態吸收不需吞嚥顆粒、對胃腸道耐受性佳、易於攜帶、可以矯味(改善不良味道,易於吞服)以及可用於較大量藥品等,且有較好的吸收穩定性,同時治療效果較易預期。此外,利用鹼金屬碳酸鹽物質的添加,可使胃內酸鹼值調升成為較鹼性環境,使質子幫浦阻斷劑(PPI)可發揮其藥效,以免克利索黴素(clarithromycin)及安莫西林(amoxicillin)等抗生素在胃內被胃酸降解,而喪失療效,進而達成有效根除H. pylori
之目的。
另一方面,前述本發明根除H. pylori
之發泡錠劑型、懸浮劑型與粉劑劑型醫藥組成物的製程中,由於醫藥組成物所含各成份係依適當之混合先後順序進行製造,且加入適合之賦形劑,因此可使各成份間不會產生交互作用,並使製得之醫藥組成物具有安定性。此外該製程方法不僅限於製造本發明根除H. pylori
之發泡錠劑型、懸浮劑型與粉劑劑型醫藥組成物,其亦可用於製造其他可根除H. pylori
