Psoriasis is a chronic inflammatory disease affecting up to 3% of the general population. The prevalence of nail involvement in psoriasis patients varies between 15% and 79%. While the nails represent a small portion of the body surface area, psoriasis in these areas can have a disproportionate influence on a patient's physical and psychosocial activities. Read More
Background: In order to treat onychomycosis, topical and systemic medications are available. The choice of a systemic or topic treatment depends on numerous factors, such as patient's age, the presence of comorbidity, responsible fungal species, the clinical form of onychomycosis, its location (fingernails or toenails), the number of nails affected and the percentage of the nail plate infected. As for topical medications, given that nail plate has an insufficiently permeable structure, it is necessary to use appropriate formulae that create in the surface of the nail plate a film able, in turn, to function both as an active ingredient's deposit and moisturising agent in nail's superficial layers in order to facilitate the spread of the active ingredient.
