The scope and potential of vaginal drug delivery.

The vagina, in addition to being a genital organ with functions related to conception, serves as a potential route for drug administration. Mainly used for local action in the cervico-vaginal region, it has the potential of delivering drugs for systemic effects and uterine targeting. Currently available vaginal dosage forms have several limitations, necessitating the need to develop novel drug delivery systems. In addition, consideration of the regulatory aspects and consumer preferences for vaginal formulations is also required in the early stages of development.
