A method for inactivating pathogens is provided. This method generally comprises the application of an effective amount of inhibitory compounds, preferably as a topical formulation, either alone or in combination with a pharmaceutically acceptable carrier or diluent. The inhibitory compounds include a copolymer of maleic acid and styrenesulfonic acid, polyvinyl phthalate sulphate, and their salts. The method can be used for preventing transmission and infection of sexual transmitted diseases, for treating and preventing bacterial vaginitis, and as a contraceptive method. These contraceptives generally have fewer side effects than conventional vaginal contraceptives (e.g., Nonoxynol-9). For example, the compounds useful in the methods of the invention not only are not toxic to natural and beneficial flora and, thus, do not upset the local microbiological balance, but also help maintain a low pH in the vaginal environment.
本文提供了一种灭活病原体的方法。这种方法一般包括施用有效量的抑制性化合物,最好是外用制剂,可以单独施用,也可以与药学上可接受的载体或稀释剂结合施用。抑制性化合物包括
马来酸和
苯乙烯磺酸的共聚物、聚
邻苯二甲酸乙烯酯
硫酸盐及其盐类。该方法可用于预防性传播疾病的传播和感染,治疗和预防细菌性阴道炎,也可用作避孕方法。与传统的阴道
避孕药(如壬苯醇-9)相比,这些
避孕药的副作用一般较小。例如,本发明方法中使用的化合物不仅对天然有益菌群没有毒性,因此不会破坏当地的微
生物平衡,而且还有助于维持阴道环境的低 pH 值。
