Therapeutic activity of lactate 12% lotion in the treatment of ichthyosis. Active versus vehicle and active versus a petrolatum cream.

Lactate 12% lotion was significantly more effective than both its vehicle and a petrolatum-based cream in the treatment of ichthyosis. The treatment regimen was twice-daily application for 4 weeks with evaluations weekly during the treatment period and for 2 weeks after treatment was stopped. Vulgaris, lamellar, sex-linked, Netherton's, and epidermolytic hyperkeratotic forms of ichthyosis were significantly improved by treatment with lactate 12% lotion. This new therapeutic modality expands the scope and extent of ichthyotic conditions that may now be successfully treated.
