Eligibility Criteria
-----------------
Inclusion Criteria: Subjects must provide written informed consent prior to any study related procedures being performed. Female subjects must have a clinical diagnosis of bacterial vaginosis, defined as having the presence of clue cells > 20% of the total epithelia cells on microscopic examination of a saline wet mount and all of the following criteria: Off-white (milky or grey), thin, homogeneous discharge; pH of vaginal fluid > 4.7; a positive 10% KOH whiff test. Subjects must be 18 years of age or older with no known medical conditions that, in the investigator's opinion, may interfere with study participation. Women of child bearing potential must have a negative urine pregnancy test result upon entry into the study. Subjects must agree to abstain from sexual intercourse throughout the first 7 days of the study. Following the first 7 days, subjects must agree to use a non-lubricated condom when engaging in sexual intercourse. Subjects must be willing to abstain from alcohol ingestion during the 5 day treatment period and for 1 day afterward. Subjects must agree to refrain from the use of intra-vaginal products throughout the study (e.g., douches, feminine deodorant sprays, spermicides, lubricated condoms, tampons, and diaphragms). Exclusion Criteria: Subjects with known or suspected other infectious causes of vulvovaginitis (e.g. candidiasis, Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae, active Herpes simplex or human papilloma virus, or any other vaginal or vulvar condition, which in the investigator's opinion, would confound the interpretation of the clinical response). Subjects with a Gram's stain slide Nugent score <4. Subjects who received antifungal or antimicrobial therapy (systemic or intravaginal) within 14 days of randomization. Subjects who have taken disulfuram within 14 days or randomization. Subjects who have demonstrated a previous hypersensitivity reaction to metronidazole, either orally or topically administered, or any form or parabens. Subjects with primary or secondary immunodeficiency. Women who will be under treatment during the study period for cervical intra-epithelial neoplasia (CIN) or cervical carcinoma. Subjects who are pregnant, breast feeding, or planning a pregnancy. Subjects who are menstruating at the time of diagnosis. Subjects with intrauterine devices. Concurrent anticoagulation therapy with coumadin or warfarin. Concurrent use of systemic corticosteroids or systemic antibiotics. Subjects with clinically significant unstable medical disorders, life threatening diseases or current malignancies. Subjects previously enrolled in this study. Subjects who have participated in another clinical trial or have taken an experimental drug within the past 30 days. Subjects who are unwilling or unable to comply with the requirements of the protocol.
