Therapeutic indications:

Clotrimazole lozenges are indicated for the local treatment of oropharyngeal candidiasis. The diagnoses should be confirmed by a KOH smear and/or culture prior to treatment. Clotrimazole lozenges are also indicated prophylactically to reduce the incidence of oropharyngeal candidiasis in patients immunocompromised by conditions that include chemotherapy, radiotherapy, or steroid therapy utilized in the treatment of leukemia, solid tumors, or renal transplantation. There are no data from adequate and well-controlled trials to establish the safety and efficacy of this product for prophylactic use in patients immunocompromised by etiologies other than those listed in the previous sentence. (See DOSAGE AND ADMINISTRATION.) Clotrimazole lozenges are contraindicated in patients who are hypersensitive to any of its components. No data available.

CLINICAL PHARMACOLOGY
Clotrimazole is a broad-spectrum antifungal agent that inhibits the
growth of pathogenic
yeasts by altering the permeability of cell membranes. The action of
clotrimazole is
fungistatic at concentrations of drug up to 20 mcg/mL and may be
fungicidal _in vitro_
against _Candida albicans_ and other species of the genus Candida at
higher
concentrations. No single-step or multiple-step resistance to
clotrimazole has developed
during successive passages of _Candida albicans_ in the laboratory;
however, individual
organism tolerance has been observed during successive passages in the
laboratory.
Such _in vitro_ tolerance has resolved once the organism has been
removed from the
antifungal environment.
After oral administration of a 10 mg clotrimazole lozenge to healthy
volunteers,
concentrations sufficient to inhibit most species of _Candida_ persist
in saliva for up to
three hours following the approximately 30 minutes needed for a
lozenge to dissolve.
The long term persistence of drug in saliva appears to be related to
the slow release of

clotrimazole from the oral mucosa to which the drug is apparently
bound. Repetitive
dosing at three hour intervals maintains salivary levels above the
minimum inhibitory
concentrations of most strains of _Candida;_ however, the relationship
between _in vitro_
susceptibility of pathogenic fungi to clotrimazole and prophylaxis or
cure of infections in
humans has not been established.
