摘要:
Novel imidazole derivatives and their acid adducts are disclosed. The imidazole derivatives are represented by formula: ##STR1## wherein R.sub.1 represents an alkyl group, R.sub.2 represents a hydrogen atom, an alkyl group which may have a substituent, or an aralkyl group which may have a substituent, provided that R.sub.1 and R.sub.2 are not both methyl groups at the same time. They have strong antimicrobial activity, especially against those fungi belonging to the genera Candida, Trichophyton, Microsporum, and Epidermorphyton, as well as against Gram-positive bacteria, and thus is useful as an antimicrobial agent.
摘要:
An external adhesive preparation comprising a steroid for treatment of skin diseases in admixture with an adhesive gel base comprising as essential components a water-soluble high molecular weight compound, water and a water-retaining agent. The external adhesive preparation is useful for treatment of skin diseases by applying the preparation spread on a soft support directly to diseased parts on the skin, thereby administering the contained steroid to the skin.
