With any of these four cytochrome P450 en- THE SKIN zymes, the variation in expression between individuals is substantial, and so their relative contribution to Most drugs that have been incorporated into creams or presystemic metabolism of drugs will vary from person ointments are applied to the skin for their local effect. However, the stratum corneum, or outer out of a cell) are also present in human intestinal ente- layer of the epidermis, forms a barrier against the rapid rocytes on the apical side nearest the lumen of the in- penetration of most drugs. The predominant transporter protein identified the relatively close-packed cellular arrangement and to date is P glycoprotein (Pgp), which is a product of the decreased amount of lipid in these cells. This transporter was originally identified highly lipid-soluble compounds will be absorbed much as being overexpressed in tumor cells and responsible in more slowly through the skin than from other sites. The part for multidrug resistance because of its role in the dermis, on the other hand, is well supplied with blood efflux of drugs out of tumor cells; thus the name mul- and lymph capillaries and therefore is permeable to tidrug resistance (MDR) gene. If that many of the drugs that are substrates for cy- penetration of the skin by lipid-insoluble compounds tochrome P450 3A4 are also substrates for Pgp. As a does occur, it is probably accomplished by diffusion substrate for Pgp, a drug will enter the cell, usually via through the hair follicles, sweat glands, or sebaceous passive diffusion, but then be picked up by the Pgp glands.
