In vivo percutaneous penetration of corticoids in man and unresolved problems in their efficacy
Abstract:
This paper review the percutaneous penetration of corticosteroids in vivo in man utilizing urinary excretion of 14C-hydrocortisone as the experimental method. In general corticosteroids are only minimally absorbed from most areas of glabrous skin. Increasing the amount that penetrates-by use of occlusion-and increasing concentration provides the most practical method currently available for increasing efficacy in treatment-resistant dermatoses. Some practical research problems relevant to topical corticoid efficacy are discussed.

The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
