CLINICAL PHARMACOLOGY
Topical corticosteroids share anti-inflammatory, antipruritic and
vasoconstrictive actions.
The mechanism of anti-inflammatory activity of the topical
corticosteroids is unclear. Various
laboratory methods, including vasoconstrictor assays, are used to
compare and predict potencies and/or
clinical efficacies of the topical corticosteroids. There is some
evidence to suggest that a
recognizable correlation exists between vasoconstrictor potency and
therapeutic efficacy in man.
PHARMACOKINETICS
The extent of percutaneous absorption of topical corticosteroids is
determined by many factors
including the vehicle, the integrity of the epidermal barrier, and the
use of occlusive dressings.
Topical corticosteroids can be absorbed from normal intact
