Therapeutic indications:

Ketoconazole Shampoo, 2% is indicated for the treatment of tinea (pityriasis) versicolor caused by or presumed to be caused by Pityrosporum orbiculare (also known as Malassezia furfur or M. orbiculare ). Note: Tinea (pityriasis) versicolor may give rise to hyperpigmented or hypopigmented patches on the trunk which may extend to the neck, arms and upper thighs. Treatment of the infection may not immediately result in normalization of pigment to the affected sites. Normalization of pigment following successful therapy is variable and may take months, depending on individual skin type and incidental sun exposure. Although tinea versicolor is not contagious, it may recur because the organism that causes the disease is part of the normal skin flora. Ketoconazole Shampoo, 2% is contraindicated in persons who have known hypersensitivity to the active ingredient or excipients of this formulation.

CLINICAL PHARMACOLOGY
Tinea (pityriasis) versicolor is a non-contagious infection of the
skin caused by
_Pityrosporum orbiculare _(_Malassezia furfur_). This commensal
organism is part of the
normal skin flora. In susceptible individuals the condition is often
recurrent and may give
rise to hyperpigmented or hypopigmented patches on the trunk which may
extend to
the neck, arms and upper thighs. Treatment of the infection may not
immediately result
in restoration of pigment to the affected sites. Normalization of
pigment following
successful therapy is variable and may take months, depending on
individual skin type
and incidental skin exposure. The rate of recurrence of infection is
variable.
Ketoconazole was not detected in plasma in 39 patients who shampooed
4-10 times per
week for 6 months, or in 33 patients who shampooed 2-3 times per week
for 3-26
months (mean: 16 months).
An exaggerated use washing test on the sensitive antecubital skin of
10 subjects twice
daily for five consecutive days showed that the irritancy potential of
ketoconazole
shampoo, 2% was significantly less than that of 2.5% selenium sulfide
shampoo.
