Pimecrolimus
Encyclopedia : P : PI : PIM : Pimecrolimus
Pimecrolimus is an immunomodulating agent used in the treatment of atopic dermatitis (eczema). It is currently available as a topical cream, marketed by Novartis, under the trade name Elidel.
Pharmacology
Pimecrolimus is an ascomycin macrolactam derivative. It has been shown in vitro that pimecrolimus binds to macrophilin-12 and inhibits calcineurin. Thus pimecrolimus inhibits T-cell activation by inhibiting the synthesis and release of cytokines from T-cells. Pimecrolimus also prevents the release of inflammatory cytokines and mediators from mast cells.Side effects
In January 2006, the United States Food and Drug Administration (FDA) announced that Elidel packaging would be required to carry a black box warning regarding the potential increased risk of lymph node or skin malignancy, as for the similar drug tacrolimus. Whereas current practice by UK dermatologists is not to consider this a significant real concern and they are increasingly recommending the use of such new drugs. Dermatologists agree that the drug should be used as a second-line remedy only after conventional methods of treatment have failed.
