Tacrolimus in psoriasis

Tacrolimus in psoriasis

Tacrolimus

• is a macrolide calcineurin inhibitor that is produced by Streptomyces tsukubaensis
  • although tacrolimus and ciclosporin inhibit calcineurin leading to suppression of T-cell activation, tacrolimus has been found to have a more potent immunological effect with a diminished vasoconstrictive and fibrinogenic effect (1)

Topical and oral administration of tacrolimus has demonstrated considerable efficacy in the treatment of psoriasis (1)

• with regard to topical tacrolimus therapy, particular utility has been observed in cases of inverse psoriasis and psoriasis affecting the face, genitalia, and nails
  • topical tacrolimus appears to have a role as a corticosteroid-sparing agent and may be associated with fewer side effects than other topical preparations
  • a systematic review stated that ".. studies demonstrated a considerable efficacy of topical administration of tacrolimus and pimecrolimus in the treatment of psoriasis, especially for facial, genital, and intertriginous areas.." (2)
