    • There is provided an ultraviolet absorber having a strong absorptive capacity in the UVA range and an absorptive capacity in the UVB range to have an ultraviolet inhibitory effect in a wide range of wavelength, increasing in an ultraviolet absorptive capacity over the course of ultraviolet irradiation time in both the UVA and the UVB ranges and having an excellent solubility. An ultraviolet absorber comprising, as an active ingredient, a compound of General Formula I: (where —OA is an alkoxy group) that exhibits an ultraviolet A wave absorptive capacity which increases over time and that has an ultraviolet B wave absorptive capacity.
    • 提供了在UVA范围内具有强吸收能力的紫外线吸收剂和在UVB范围内的吸收能力,在宽波长范围内具有紫外线抑制作用,在紫外线照射时间内增加紫外线吸收能力 UVA和UVB两者都具有优异的溶解性。 一种紫外线吸收剂,其特征在于,含有通式I的化合物(其中-OA为烷氧基),其表现出随时间而增加并具有紫外线B吸收能力的紫外线A吸收能力。

    • The present invention relates to nonaqueous preparation for percutaneous absorption prepared by laminating an adhesive layer comprising a nonsteroidal anti-inflammatory analgesic in an alkali metal salt form, and an inorganic acid which is strongly acidic compared with the nonsteroidal anti-inflammatory analgesic in a free form, together with a nonaqueous base, on a support. According to the present invention, drug-releasing characteristics and skin penetration in a nonaqueous preparation for percutaneous absorption can be improved because the addition of an inorganic acid in a nonaqueous base containing a drug in an alkali metal salt form leads to an improvement in the solubility of the drug in the base, and a good partitioning of the drug to skin surface. In addition, as the inorganic acid has no alcoholic hydroxy group in the structure, the inorganic acid does not react with the drug, therefore it causes no lowering in the stability of the drug by esterification.
    • 本发明涉及通过层压含有碱金属盐形式的非甾族抗炎止痛剂的粘合剂层和与游离形式的非甾体抗炎止痛剂相比强酸性的无机酸制备的用于经皮吸收的非水性制剂 ,与非水性基质一起在载体上。 根据本发明,通过在含有碱金属盐形式的药物的非水性碱中添加无机酸,能够提高用于经皮吸收的非水系制剂中的药物释放特性和皮肤渗透性,从而提高溶解性 的药物在基础上,并且药物与皮肤表面的良好分配。 此外,由于无机酸在结构中不含醇羟基,所以无机酸不与药物反应,因此通过酯化不会降低药物的稳定性。
