Abstract:
<em>The nail disorders are mainly due to fungal infection. When the drug is given through oral or systemic route, the potency of drugs gets decreased at the site of action. To avoid this loss of drug potency topical route of administration is used. This review is mainly about transungual drug delivery which means transfer of drug across the keratinized nails to treat nail fungal diseases and increasing bioavailability of various drugs used for nail diseases. Nail diseases are mainly caused by fungal infections; fungi are most responsible for nail diseases. So treatment of such infections is no

Abstract:
Topical therapy is highly desirable in treating nail disorders due to its localized effects, which results in minimal adverse systemic events and possibly improved adherence. The absorption of drugs into the nail unit, to the nail plate, is highly desirable to treat nail disorders; however, the effectiveness of topical therapies is limited by minimal drug permeability through the nail plate. Nail permeability is however quite low and limits topical therapy to early/mild disease states such as onychomycosis (fungal infections of the nail).

Topical therapy of antifungals is primarily restricted due to the low innate transport of drugs through the thick multi-layered keratinized nail plate.

Abstract:
ABSTRACT Introduction: Nail psoriasis treatment is challenging due to difficult drug delivery and systemic therapy toxicities. Self-dissolvable microneedle patches embedded with corticosteroids offers a potentially rapid, minimally invasive drug delivery platform with good efficacy and minimal adverse side effects. Methods: We conducted a 4-month prospective randomised controlled trial. Subjects with psoriatic nails were randomised to receive microneedle device delivered topical steroids on one hand and control treatment (topical Daivobet gel) on the other. Two independent dermatologists blind

Abstract:
Naftifine is used to treat fungal skin infections as it inhibits dermatophytes, which are the cause of onychomycosis. However, naftifine’s ability to permeate the human nail barrier has not been investigated, thus, the antimycotic potential is not clearly established. This work aims to evaluate the effect of penetration enhancing factors on the accumulation of naftifine hydrochloride through human nail clippings. Naftifine polymeric nail lacquers with Eudragit RL100 were developed as a suitable delivery system. Low penetration of naftifine into nail has been determined as less than 10% of appl

Abstract:
Inkjet printing (IJP) is an emerging technology for the precision dosing of medicines. We report, for the first time, the printing of the antifungal drug terbinafine hydrochloride directly onto nails for the treatment of onychomycosis. A commercial cosmetic nail printer was modified by removing the ink from the cartridge and replacing it with an in-house prepared drug-loaded ink. The drug-loaded ink was designed so that it was comparable to the commercial ink for key printability properties. Linear drug dosing was shown by changing the lightness of the colour selected for printing (R2 = 0.977)

Abstract:
Nail is a strong and resistant structure, characterized by a low permeability to foreign molecules. Nails can be subjected to many diseases, among which fungal infections (e.g. onchomycosis) are the most common and responsible for nail structure alteration. Many formulations have been produced for the delivery of active ingredients to treat nail disorders, based on newly synthesized active molecules or containing chemical enhancers or chemically-modified polymers able to improve the drug transungual penetration. To avoid permanent alterations of the nail structure due to the use of chemical co

Abstract:
Background: Onychomycosis is a nail fungal infection which accounts for 50% of the nail diseases and is characterized by disfigurement and discoloration of nails. The current therapy includes oral and topical formulations both of which come with their own drawbacks. This has left a room for developing patient- compliant novel strategies which can facilitate drug delivery deeper into the nails effectively. Objective: The main objective of the present work was to develop and evaluate in situ gelling thermosensitive hydrogel as an aqueous nail lacquer for the treatment of onychomycosis. The idea

Abstract:
The efficacy of topical antifungal therapy in onychomycosis has been hindered by the failure of the antimycotic to permeate the nail plate. This research aims to design and develop a transungual system for the effective delivery of efinaconazole utilizing constant voltage iontophoresis. Seven prototype drug-loaded hydrogel formulations (E1–E7) were prepared to assess the influence of solvent (ethanol) and cosolvent (Labrasol®) on transungual delivery. Optimization was performed to evaluate the effect of three independent variables; voltage, solvent-to-cosolvent ratio, and penetration enhancer

Abstract:
Aqueous-based nail lacquers have shown potential in promoting the diffusion of drugs into the nail. In our laboratory, we have recently developed a transungual delivery system based on an aqueous dispersion of cyclodextrin-poloxamer soluble polypseudorotaxanes, supramolecular host−guest assemblies that improves the drug permeation into the nail. However, the high-water content and the rheological and adhesive properties of this lacquer negatively affect properties that play a fundamental role in the patients’ acceptance such as stickiness, nail film formation or drying rate, properties.

Abstract:
The successful topical therapy of onychomycosis depends on effective drug release and penetration into nail, which can be achieved by using an adequately developed delivery system. This study evaluated and compared effect of film-forming polymers Eudragit RL100, Eudragit RS100, and ethyl cellulose on naftifine hydrochloride release from experimental nail lacquer formulations. Quality of formulations was evaluated by determining drying time and water resistance. Interactions between active pharmaceutical ingredient and excipients were investigated using microcalorimetry and FT-IR. Optimization
