TRANSUNGAL DRUG DELIVERY SYSTEMS

Abstract
The body normally hosts a variety of microorganisms, including
bacteria and fungi. Some of these are useful to the body and others
may cause infections. Fungi can live on the dead tissues of the hairs,
nails. Continuous exposal of nail to warm, moist environments usually
develops nail infection. Nail plate is main route for penetration of drug.
Varity of conventional formulation like gel, cream and also oral
antifungal are available for treatment of nail infection. The nail lacquer
is a new drug delivery system in treatment of nail infections. The
major hurdle associated with developing nail lacquers treatment for
nail disorders is to deliver the active (antifungal) therapeutically
effective concentrations to the site of infection, which is often under
nail. However possible means to enhance nail penetration must be
explored in greater depth before effective local treatments for fungal nail infections are
developed. Lack of proper in vitro methods to measure the extent of drug permeation across
the nail plate is the major difficulty in the development of transungual delivery. Penetration
of topical antifungal through the nail plate requires a vehicle that is specifically formulated
for transungual delivery. Recent focus is emphasizing on development of a promising
antifungal treatment in form of nail lacquer owing to its beneficial advantages.
Keywords: Nail, Transungual delivery, Nail plate.
