Alclometasone is a syntheticcorticosteroid for topical dermatologic use, possessing anti-inflammatory, antipruritic, and vasoconstrictive properties.[2][3]

Theprodrugalclometasone dipropionate was originally marketed under the brand nameAclovate byGlaxoSmithKline as a topical cream and ointment. However, generic versions of the drug are available.

Medical uses

[edit]

Alclometasone cream and ointment are indicated for the relief of corticosteroid-responsive dermatoses, including:

Alclometasone may be used on sensitive skin sites (face, skinfolds); in pediatric patients 1 year or older and in geriatric patients.

Contraindications

[edit]
  • hypersensitivity to alclometasone or any of ingredients in pharmaceutical forms
  • cutaneoustuberculosis
  • chicken pox
  • perioral dermatitis
  • acne
  • rosacea
  • open wounds
  • trophic ulcers
  • viral infection of skin
  • skin manifestations of syphilis

Side effects

[edit]

Adverse reactions (sometimes, less than 1-2% cases) include:

Pharmacology

[edit]

Alclometasone induces the production of lipocortins, formally known asannexins, which inhibitphospholipase A2 – the enzyme responsible for the synthesis ofarachidonic acid. Without the oxidation of arachidonic acid,eicosanoids, such asprostaglandins,thromboxanes, andleukotrienes, can't be produced.

Alclometasone also inhibits the release of pro-inflammatory mediators from leukocytes (e.g.,cytokines,histamine, leukotrienes,serotonin).

Formulations

[edit]

Alclometasone as Aclovate is supplied in:

  • Cream; Topical; 0.05%
  • Ointment; Topical; 0.05%
