Drugs used in Vaginal and Vulval condition

Pharmacology

Metronidazole is converted to reduction products that interact with DNA to cause destruction of helical DNA structure and strand leading to a protein synthesis inhibition and cell death in susceptible organisms. It is active against most anaerobic protozoa, some gm+ve, gm-ve and facultative anaerobes.

Miconazole inhibits ergosterol synthesis thus damaging fungal cell wall membrane and increases its permeability, allowing leakage of nutrients.

Dosage & Administration

In trichomoniasis, concurrently with oral metronidazole treatment and 1 vaginal tablet should be inserted high up into the vagina once a day (preferably before going to bed at night) for 10 days. Long-term recovery may be expected only is response to the simultaneous oral treatment of both partners.

In candidiasis or other fungal infections, 1 vaginal tablet has to be inserted high up into the vagina for 10 days. The vaginal tablet should be slightly moistened before application.
