Description
本發明關於一種作為治療光化性角化症的醫藥之局部性組成物。
光化性角化症係一種表皮的原位癌。其關於侷限增生於表皮之轉形的角質細胞,特徵在於尤其是腫瘤抑制基因p53及端粒酶基因之高度突變。其更與典型地也發生於侵犯性皮膚扁平細胞癌之特徵性染色體變異有關聯。在所有罹患光化性角化症患者的約10%中,以及更特定地併有免疫抑制症之患者的約30%中,該病況期間的進一步發展會成為皮膚的扁平細胞癌。因此,光化性角化症之確診一般地構成治療之指標。
光化性角化症之療法中,不同的外科手術及理學方法諸如冷凍手術、刮除術、切除療法、雷射療法及軟x光療法已被提出。並且,不同形式的用於治療光化性角化症之藥學療法係已知。例如,環氧化酶抑制劑諸如二克氯吩(diclofenac),抗代謝劑諸如5’-氟脲嘧啶以及免疫調節劑諸如咪喹莫特(imiquimod)已被用於治療光化性角化症。
光化性角化症之藥學療法通常藉由對應藥物之局部性施用來實行,特定地係以水為基底的霜劑與膠劑形式或酒精性溶液之形式。
有關習知技藝已知之以水為基底的霜劑與膠劑配方,已發現係不利的,因這些配方必須被搓揉入皮膚中。在搓揉霜劑或膠劑配方的過程,所包含於其中的活性藥劑典型地會被塗佈於皮膚上一大塊區域。因此,很難將以水為基底的霜劑與膠劑配方特定地施用在確實需要治療的皮膚區域上。關於酒精性溶液,已發現這些配方,特別是施用在經常發生光化性角化症的頭部與臉部區域時,傾向流動。因此,酒精性溶液也不適於精準的調整活性藥劑之劑量。因為其等不適於調特定劑量,依據習知技藝之配方係被與不必要的皮膚區域接觸而增加了副作用的程度與危險。並且,已發現諸如5’-氟脲嘧啶之藥物在保存於水性或酒精性配方中對應於該等配方典型的保存期限一段期間就會結晶出來。
WO-A-96/32112揭露用於治療皮膚光化性損傷之組成物,其包含5’-氟脲嘧啶、一表面皮膚剝離劑及一藥學上可接受的載劑,特定為一酒精性溶液形式。用於治療急性光化性角化症,5’-氟脲嘧啶含量為5至10%係被建議。已發現局部性施用包含這些含量的5’-氟脲嘧啶之組成物會引發實質副作用。並且,所描述的酒精性溶劑當局部地施用在皮膚表面會流動。
