CLINICAL PHARMACOLOGY
Topical application of hydroquinone produces a reversible
depigmentation of the skin by inhibition of
the enzymatic oxidation of tyrosine to 3,4-dihydroxyphenylalanine
(dopa) (Denton, C. et al., 1952) and
suppression of other melanocyte metabolic processes (Jimbow, K. et
al., 1974) . Exposure to sunlight
or ultraviolet light will cause repigmentation of bleached areas
(Parrish, J.A. et al., 1978) .
INDICATIONS AND USAGE
Hydroquinone USP, 4% Skin Bleaching Cream is indicated for the gradual
bleaching of
hyperpigmented skin conditions such as chloasma, melasma, freckles,
senile lentigines, and other
unwanted areas of melanin hyperpigmentation.
CONTRAINDICATIONS
Prior history of sensitivity or allergic reaction to hydroquinone or
to any of the ingredients of the
product. The safety of topical hydroquinone use during pregnancy or
for children (12 years and under)
has not been established.
