Abstract
Percutaneous absorption of hydrocortisone was measured in four children and three adults with atopic dermatitis after the application of 1% hydrocortisone cream and again 12 h after the application of a moisturizer containing 80% water and 5% propylene glycol to the same areas. A significant increase in the level of the plasma cortisol was observed after both applications and these levels were still elevated at 24 h. Topically applied hydrocortisone, stored in eczematous skin, could be released from this reservoir by a moisturizer containing propylene glycol.
