Description
本發明係關於含有二克氯吩鈉(dichlofenac sodium)作為有效成分之經皮吸收型水性貼劑。更詳言之,本發明係關於二克氯吩鈉之溶解安定性優異,該藥物之初期釋出速度優異,同時該藥物亦可持續釋出之含有二克氯吩鈉之經皮吸收型水性貼劑。
近年來,許多非類固醇性消炎鎮痛劑為了經皮吸收而製劑化,且廣泛的使用於慢性風濕症、變形性關節炎、變形性脊椎症、腰痛症等各種炎症疾病。尤其二克氯吩鈉由於具有優異之消炎鎮痛作用,故已作為經口劑或栓劑在臨床上被廣泛使用。然而,另一方面亦已知展現以腸胃障礙為代表之各種副作用。
為了減輕該等副作用而對二克氯吩鈉的經皮吸收外用劑進行探討。
尤其外用貼劑由於可控制藥物投予量同時可對貼附部正下方之患部直接移行藥物,故而可效率良好地持續治療。然而,二克氯吩鈉對水或油性成分之溶解性極差,不僅難以製作二克氯吩鈉於製劑中完全融解的貼劑,且即使過量添加二克氯吩鈉溶解劑等製作完全溶解型之貼劑,亦難以以貼劑中結晶不析出之溶解狀態長期保存。且,若於水性貼劑中高濃度地調配對二克氯吩鈉的溶解性高之油性成分,則與其他成分之相溶性變差,容易引起相分離,而無法長期安定地保存。此外,由於二克氯吩鈉之經皮吸收性通常較低,欲改善該等問題以往雖已進行各種檢討或努力,但現狀仍無法獲得解決上述問題點之製劑。
例如,於下述專利文獻1中,已提案有於二克氯吩鈉中添加克羅米通(crotamitone)及弱酸性脂肪酸使藥物成為自由體藉此提高經皮吸收性之貼劑。然而,藉由使二克氯吩鈉成為自由體,有使二克氯吩鈉之安定性降低之可能性,且其藥物之經皮吸收性尚無法稱為充分。
下述專利文獻2中,雖提案有由含有二克氯吩鈉之藥劑層及不含之基劑層的兩層所構成之經皮吸收效率良好、經時變化少之貼劑,但以該方法分別調製延展藥劑層及基劑層後,必須經過貼合步驟,而有步驟管理複雜、經濟效率等問題。
於下述專利文獻3中,雖提案有含有二克氯吩鈉、以由1-薄荷醇及丙二醇所成之吸收促進劑以及水溶性聚合物為主體之親水性基劑之水性貼劑,但二克氯吩鈉於該貼劑中之溶解性低,於長期保存中有該藥物結晶化之虞,且該藥物之經皮吸收性亦無法稱為充分。
於下述專利文獻4中,雖提案有調配1-薄荷醇及吡咯烷酮類(吡咯烷酮或其衍生物之至少一種)作為二克氯吩鈉之經皮吸收促進劑,但二克氯吩鈉於該貼劑中之溶解性低,於長期保存中有該藥物結晶化之虞,且該藥物之經皮吸收性亦無法稱為充分。

本發明之目的係提供一種二克氯吩鈉之溶解安定性與經皮吸收性優異之水性貼劑。亦即,本發明提供一種即使長時間保存亦沒有辨識到膏體中藥物之結晶析出,藥物之初期釋出速度優異,同時亦可持續的釋出其藥物之水性貼劑。
本發明人等為解決前述課題而重複積極研究之結果,驚人地發現於克羅米通及水中,對於以該等單獨幾乎不溶解之二克氯吩鈉,藉克羅米通/二克氯吩鈉為8.0以下之調配比率,且(水+克羅米通)/二克氯吩鈉之調配比率為3.0~20.0之範圍混合之由克羅米通/水/二克氯吩鈉所組成之混合溶液,意外地發現可提高二克氯吩鈉之溶解性,可調製二克氯吩鈉之完全溶解液(以下於本發明中稱為二克氯吩鈉主藥液)。
據此,藉由將該混合溶液調配於水性貼劑中,可獲得在膏體中未見到結晶,二克氯吩鈉之溶解安定性優異,藥物之初期釋出速度優異,同時其藥物亦可持續釋出之水性貼劑。
亦即,本發明係提供一種二克氯吩鈉之溶解安定性優異,藥物之初期釋出速度優異,同時亦可持續釋出其藥物之水性貼劑者,其係藉由於水性貼劑中調配以使克羅米通/二克氯吩鈉為8.0以下,且(水+克羅米通)/二克氯吩鈉為3.0~20.0之範圍之調配比率混合而獲得之均勻混合溶液(本發明中之二克氯吩鈉主藥液)。
以下針對本發明之二克氯吩鈉水性貼劑之最佳實施形態更詳細說明。
本發明之水性貼劑之有效成分的二克氯吩鈉在膏體中之調配量為0.1~5重量%,較好為0.5~2.5重量%。調配量未達0.1%時由於其藥理效果差故不佳,相反地調配量超過5重量%時,二克氯吩鈉之結晶容易析出,且製劑之物性惡化。
克羅米通在膏體中之調配量為1.5~5重量%,較好為2~4重量%。少於1.5重量%時無法調製二克氯吩鈉‧水‧克羅米通之混合溶液,膏體中之二克氯吩鈉之溶解性降低,初期之經皮吸收性不足。另一方面,多於5重量%時,與其他成分之相溶性變差,發生克羅米通朝膏體表面滲出,且二克氯吩鈉之釋出或製劑之黏著力降低,難以長時間維持良好之製劑物性。
本發明中,水是除了調製二克氯吩鈉主藥液之必須成分以外,亦為作為水性貼劑之膏體成分的水溶性高分子等之溶解劑之必要成分。本發明之二克氯吩鈉主藥液調製用之水係以相對於膏體重量係以0.5~20%,較好以1~10%之範圍調配。該調配量在該範圍以外時無法調製均勻之二克氯吩鈉主藥液。另外,膏體成分溶解用之水之調配量(亦包含預先於調配成分中所含之水量,例如20%聚丙烯酸水溶液中所含之水量)係考慮膏體組成、及二克氯吩鈉調製用水之調配量之均衡而調配,但相對於膏體重量係以20~50重量%,較好以30~45重量%之範圍調配。
水之總重量相對於膏體係以20~70%,較好以30~60重量%之範圍調配。調配量超過70重量%時,發現因膏體黏度下降造成保形性惡化以及發黏現象。且,黏著力顯著下降,無法獲得對黏貼部位之充分接著性故而不佳。另一方面,調配量未達20重量%時,膏體黏度變得太高使製造時之作業性惡化。又,由於製劑之黏著力變得太強,使得剝離時產生痛楚而產生皮膚刺激故而不佳。
本發明特徵之本發明之二克氯吩鈉主藥液之組成比為克羅米通/二克氯吩鈉在8.0以下,且(水+克羅米通)/二克氯吩鈉在3.0~20.0之範圍。該等成分若在該組成比以外,則無法調製均勻之二克氯吩鈉主藥液。
構成水性貼劑之膏體成分只要是一般製造水性貼劑時使用之膏體成分則無特別限制,例如可調配水性高分子、保濕劑、賦形劑、安定化劑、交聯劑、抗氧化劑、清涼化劑、溫感刺激劑等。
水性高分子可將例如明膠、水解明膠、聚丙烯酸、聚丙烯酸鈉、聚丙烯酸部分中和物、聚丙烯酸澱粉、聚乙烯醇、聚乙烯吡咯烷酮、羥基丙基纖維素、羥基丙基甲基纖維素、羥基乙基纖維素、甲基纖維素、羧甲基纖維素鈉、羧基乙烯基聚合物、甲氧基乙烯馬來酸酐共聚物、N-乙烯基乙醯胺共聚物、黃原膠(xanthan gum)、阿拉伯膠等單獨或兩種以上組合使用,尤其以組合使用聚丙烯酸、聚丙烯酸部分中和物、羧甲基纖維素鈉最佳。
保濕劑之例可將濃甘油、D-山梨糖醇液、1,3-丁二醇、二丙二醇、聚乙二醇等單獨或組合兩種以上使用。

本實施例與比較例之處方一覽表分別示於表2、表3。
針對實施例1~4、比較例1~2、9~11及12,以偏光顯微鏡觀察在20℃之條件下放置24小時後與在40℃下放置兩個月後之膏體中二克氯吩鈉結晶析出之有無。觀察結果示於表4。
針對實施例1~4及比較例1~2、9~11及12,使用裸毛大鼠皮膚評價二克氯吩鈉之皮膚透過性。將裸毛大鼠背部皮膚剝離,將真皮側作為接受層側,安裝於使37℃之溫水在外周部循環之Franz型電池(1.77cm2
,10mL)中。於角質層側貼附製劑,於接受層使用pH7.4之磷酸緩衝溶液(PBS),經時地進行接受溶液之取樣。針對各時間每次取樣之接受溶液,利用高速液體層析法對所透過之二克氯吩鈉量進行定量。由所得數據算出每單位時間及每單位面積之皮膚透過速度,求得實施例1~4及比較例1~2、9~11及12之第2小時及第24小時之皮膚透過速度之結果示於表5。
且本實施例3及比較例9~11中,透過裸毛大鼠皮膚之二克氯吩鈉之皮膚透過速度與時間之關係示於圖1。
將實施例1~4及比較例1~2、9~11及12所得之二克氯吩鈉水性貼劑置入遮光性氣密容器中,在溫度40℃之條件下保存1個月及2個月。於各測定日自保存條件下取出,進行甲醇加熱回流萃取。充分冷卻後,以液體層析法測定萃取液,測定製劑中二克氯吩鈉濃度之結果示於表6。
由上述各實驗結果,可知實施例1~4為製劑安定性及藥物之皮膚透過性均優異之製劑。另一方面,比較例於製造後之保存試驗中,有關比較例1~2及9~11,製劑中有結晶析出,尤其比較例10若亦一併考慮實驗例6之結果,不僅有結晶析出,且為二克氯吩鈉藥物本身之安定性亦低之製劑。再者有關比較例1~2、9、11及12,與各實施例比較,亦判定藥物之皮膚透過性亦差。
依據本發明,可提供二克氯吩鈉之溶解安定性及經皮吸收性優異之水性貼劑。
圖1為顯示實驗例3之透過裸毛大鼠皮膚之二克氯吩鈉之透過速度與時間之關係之作圖。
