This invention relates to methods of increasing the efficacy of peroxides such as benzoyl peroxide in the treatment of skin conditions such as acne. In a preferred embodiment, the invention relates to methods of increasing radicals formed by peroxides on/in the skin, more specifically near/in the comedone, for topical use in dermatology. In a specific embodiment, the invention relates to the use of transitional metals such as Cu(1) and ferrous ions to increase the efficacy of peroxides such as benzoyl peroxide. In another embodiment, the invention relates to a method by which a peroxide such as benzoyl peroxide and its activator are added to the skin surface at the same time. In another embodiment, the invention relates to the use of a more soluble form of peroxide such as benzoyl peroxide to increase its efficacy. In another embodiment, the invention relates to the addition of a side chain to a peroxide such as benzoyl peroxide so that it is activated by light. In a further embodiment, the invention relates to the addition of a tertiary amine to a peroxide such as benzoyl peroxide at the time of skin application, to improve the efficacy of the peroxide. In another embodiment, the invention relates to the addition of dapsone or other material to a peroxide such as benzoyl peroxide to improve its efficacy.
本发明涉及提高过氧化物(如过氧化苯甲酰)治疗皮肤病(如痤疮)疗效的方法。在一个优选的实施方案中,本发明涉及增加过氧化物在皮肤(更具体地说是在粉刺附近)形成的自由基的方法,用于皮肤科的局部使用。在一个具体的实施方案中,本发明涉及使用过渡金属如铜(1)和亚铁离子来提高过氧化物如过氧化苯甲酰的功效。在另一个实施方案中,本发明涉及一种将过氧化物(如过氧化苯甲酰)及其活化剂同时添加到皮肤表面的方法。在另一个实施方案中,本发明涉及使用过氧化苯甲酰等过氧化物的更易溶形式来提高其功效。在另一个实施方案中,本发明涉及在过氧化苯甲酰等过氧化物中添加侧链,使其被光激活。在另一个实施方案中,本发明涉及在皮肤使用过氧化苯甲酰等过氧化物时添加叔胺,以提高过氧化物的功效。在另一个实施方案中,本发明涉及向过氧化苯甲酰等过氧化物中添加达泊松或其他材料,以提高其功效。
