U40 Foam - Clinical Pharmacology
Urea, topically applied, dissolves the intercellular matrix of the skin which can result in enhanced shedding of scaly, dry skin which causes a softening of the hyperkeratotic areas of the skin. Applied to the nail plate topically, urea has a similar effect on the intercellular matrix of the nail plate.
The mechanism of action of topically applied urea is not yet known.
Indications and Usage for U40 Foam

Urea, topically applied, is useful for the treatment of hyperkeratotic conditions such as dermatitis, xerosis, ichthyosis, psoriasis, eczema, keratosis, keratoderma and dry, rough skin, as well as corns and calluses. It is also useful in the treatment of damaged, ingrown and devitalized nails.
