Topical urea is bacteriostatic, bactericidal, fungistatic, proteolytic, hygroscopic and has mild local anesthetic properties. These actions are dose dependent. Most of its therapeutic applications depend on its hygroscopic properties. The hygroscopic property is due to its ability to cause configurational change in proteins in the stratum corneum. A 10% urea cream has been shown to increase the water holding capacity of ichthyotic scale by 100% after 3 weeks of treatment. There is no information available about percutaneous absorption of urea. Therapeutic effects depend on local concentrations, not on systemic absorption of the drug. If absorbed, urea would be excreted unchanged in the urine.
This is contraindicated in any other ingredient of this preaparation.
No serious toxicity has been reported with topical urea. Historically it is considered a safe drug. But on some occasions, topical urea has been shown to cause burning and irritation, if applied to inflamed, broken or exudative skin eruptions.
Urea cream can be used during pregnancy and lactation.
In some instances, urea 10% cream may cause local irritation and edema, when applied to sensitive skin. If the condition is aggravated or there is no improvement the doctor should be consulted. Avoid application to moist or broken skin.
