Medication Summary

Drug regimens for eczema should be tailored to the individual patient to reduce the frequency and severity of exacerbations.

Topical steroids

Class Summary

Topical steroids are very effective when used in the induction of remission and in the acute exacerbation of atopic dermatitis.

Low-to-medium potency steroids should be used routinely, with medium-to-high potency steroids for more severe rashes.

Triamcinolone topical (Aristocort)

 

A medium potency topical steroid. Treats inflammatory dermatosis responsive to steroids. Decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reversing capillary permeability.

Hydrocortisone topical

 

An example of a low-potency topical steroid available OTC. An adrenocorticosteroid derivative suitable for application to skin or external mucous membranes. Has mineralocorticoid and glucocorticoid effects resulting in anti-inflammatory activity.

Topical calcineurin Inhibitors

Class Summary

Topical immune suppressants that block early T-cell activation, degranulation of mast cells, and multiple cytokines.

Pimecrolimus (Elidel cream)

 

First nonsteroid cream approved in the US for mild-to-moderate atopic dermatitis. Derived from ascomycin, a natural substance produced by fungus Streptomyces hygroscopicus var ascomyceticus. Selectively inhibits production and release of inflammatory cytokines from activated T cells by binding to cytosolic immunophilin receptor macrophilin-12. The resulting complex inhibits phosphatase calcineurin, thus blocking T-cell activation and cytokine release. Cutaneous atrophy was not observed in clinical trials, a potential advantage over topical corticosteroids. Indicated only after other treatment options have failed.

Tacrolimus ointment (Protopic)

 

The mechanism of action of tacrolimus in atopic dermatitis is not known. Reduces itching and inflammation by suppressing the release of cytokines from T cells. Also inhibits transcription for genes that encode IL-3, IL-4, IL-5, GM-CSF, and TNF-alpha, all of which are involved in the early stages of T-cell activation. Additionally, may inhibit release of preformed mediators from skin mast cells and basophils, and downregulate expression of FCeRI on Langerhans cells. Can be used in patients as young as 2 years. Drugs of this class are more expensive than topical corticosteroids. Available as an ointment in concentrations of 0.03% and 0.1%. Indicated only after other treatment options have failed.

Oral immunosuppressive agents

Class Summary

For use in severe refractory atopic dermatitis.

Cyclosporine (Neoral, Sandimmune)

 

An 11-amino acid cyclic peptide and natural product of fungi. Acts on T-cell replication and activity.

Specific modulator of T-cell function and an agent that depresses cell-mediated immune responses by inhibiting helper T-cell function. Preferential and reversible inhibition of T lymphocytes in G0 or G1 phase of cell cycle suggested.

Binds to cyclophilin, an intracellular protein, which, in turn, prevents formation of interleukin 2 and the subsequent recruitment of activated T cells.

Has about 30% bioavailability, but there is marked interindividual variability. Specifically inhibits T-lymphocyte function with minimal activity against B cells. Maximum suppression of T-lymphocyte proliferation requires that drug be present during first 24 h of antigenic exposure.

Suppresses some humoral immunity and, to a greater extent, cell-mediated immune reactions (eg, delayed hypersensitivity, allograft rejection, experimental allergic encephalomyelitis, and graft-vs-host disease) for a variety of organs.

Antihistamines

Class Summary

Used for the sedating effects. Help to prevent scratching during sleep.

Hydroxyzine hydrochloride (Atarax, Vistaril)

 

Antagonizes H1-receptors in the periphery. Also may suppress histamine activity in the subcortical region of the CNS. A sedating antihistamine.
