Abstract

The invention provides a nano-silver emulsifiable paste and its preparation method and relates to the field of medicines. The nano-silver emulsifiable paste is an O/W type emulsifiable paste or W/O type emulsifiable paste which is prepared by a certain preparation technology with nano-silver being used as a main drug. The nano-silver emulsifiable paste can be used for treating infection of infected wounds and body surface chronic ulcer (venous ulcer, pressure ulcer and the like) caused by burn and scald and physical and mechanical damage and for promoting healing of the wounds. The O/W type emulsifiable paste is similar to a moistening burn cream and can provide burn and scald wounds with a moistening environment which is beneficial to tissue regeneration. Simultaneously, due to specific high antibacterial activity and good wound heating promotion effect of the nano-silver, the nano-silver emulsifiable paste is better than the moistening burn cream; and in comparison with sulfadiazine silver and other external-use anti-infection drugs, the nano-silver emulsifiable paste is beneficial to wound healing, has no bacterial drug resistance and has high antibacterial activity.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a nano-silver cream and a preparation method thereof. Background technique [0002] Burns and other traumas caused by other reasons are relatively common clinically, especially during wartime. External use of anti-infective drugs to prevent the deepening of wound bacterial invasion is the initial and important part of the whole treatment process. The commonly used drug at present is silver sulfadiazine. After a long period of application, it is found that the drug has side effects of deepening the wound surface and delaying healing, and the drug-resistant bacteria of the drug have been found clinically. [0003] The problem of bacterial drug resistance is becoming more and more serious. It not only makes the patient's condition difficult to cure for a long time, brings great physical and mental pain and heavy economic burden to the patient and family, but also increases the medical cost o...
