Vaginal acidity is maintained under natural conditions through the functional activity of vaginal epitheliocytes and lactobacilli. If the environmental pH is unstable, vaginal acidity may be corrected with local lactic acid preparations; in this connection there can be no question that investigations of the efficacy of novel current acid-containing drugs, their dosage, and treatment regimens for bacterial vaginosis are urgent and promising. The first Russian designed lactic acid-containing vaginal suppositories 100 mg (femilex) are becoming an alternative to conventional antibacterial therapy for bacterial vaginosis. It is possible that lactic acid therapy in the decreased, but preserved lactoflora will be able to rule out the second stage of using of probiotics.</p></abstract><trans-abstract xml:lang="ru"><p>Роль молочной кислоты (МК) в поддержании гомеостаза вагинального биотопа весьма значима. В естественных условиях поддержание кислотности влагалища происходит благодаря функциональной активности влагалищных эпителиоцитов и МК-бактерий. В случаях нарушения стабильности рН среды коррекция кислотности влагалища может быть осуществлена с помощью местного применения препаратов МК, в связи с чем актуальность и перспективность исследований по изучению эффективности новых современных кислотосодержащих препаратов, их доз и схем лечения бактериального вагиноза не вызывают сомнения. Впервые разработанные в России суппозитории с МК в дозе 100 мг (фемилекс) становятся альтернативой традиционной антибактериальной терапии бактериального вагиноза. Возможно, что терапия МК при сниженной, но сохраненной лактофлоре сможет исключить второй этап применения пробиотиков.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lactobacilli</kwd><kwd>lactic acid</kwd><kwd>femilex vaginal suppositories</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лактобактерии</kwd><kwd>молочная кислота</kwd><kwd>вагинальные свечи фемилекс</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кира Е.Ф.
