Vaginal tablets of dequalinium chloride 10 mg versus clotrimazole 100 mg for vaginal candidiasis: a double-blind, randomized study

Dequalinium Chloride for the Treatment of Vulvovaginal Infections: A Systematic Review and Meta-Analysis

OBJECTIVE/PURPOSE

Women at reproductive age frequently experience vulvovaginal infections and vaginitis. The most common etiologies are vulvovaginal candidiasis (VVC), bacterial vaginosis (BV), desquamative inflammatory vaginitis/aerobic vaginitis, and trichomoniasis. Various treatment options are available for these infections, such as specific antimicrobial or antiseptic agents. Dequalinium chloride (DQC) is a local antiseptic agent with a broad antimicrobial and antifungal spectrum. Multiple studies suggest that DQC is an efficient treatment for vaginal infections; however, it is not widely recommended as a first-line treatment. This systematic review and meta-analysis aims to evaluate the efficacy of DQC compared with that of standard treatment.

METHODS

Our systematic review was conducted according to the PRISMA guidelines. PubMed/MEDLINE, EMBASE, CENTRAL, and clinicaltrials.org were searched to retrieve relevant reports up to October 2022.

RESULTS

Four randomized controlled studies and 1 observational study were included in this review. Overall, DQC showed noninferiority to the reference treatments for BV and VVC, and to the evaluated treatment options for desquamative inflammatory vaginitis/aerobic vaginitis. For BV and VVC, this could also be confirmed in a meta-analysis including 3 randomized controlled studies. No serious adverse events were reported in any of these studies.

CONCLUSIONS

Dequalinium chloride offers a safe, well-tolerated, and efficient treatment option for vulvovaginal infections of different etiologies. However, further studies are needed to confirm our findings and allow inclusion of DQC as a first-line treatment into guidelines.

Novel Antifungals for the Treatment of Vulvovaginal Candidiasis: Where Are We?

Vulvovaginal candidiasis (VVC) is a common health-related issue and the second most common cause of vaginitis. Previously, azole antifungals were the mainstay of VVC treatment. Additionally, boric acid and nystatin have been used topically for management of VVC. Despite being effective and well tolerated by most patients, the use of azoles may be limited in some cases. Currently, two new antifungal agents have received US Food and Drug Administration approval for use in the management of VVC. In this article, we briefly review treatment regimens used for the management of VVC over the past decade, the newly approved agents and their possible clinical application, and future treatment considerations.
