Oxiconazole nitrate

Oxiconazole nitrate is a broad spectrum antifungal which can inhibit the growth of T. tonsurans and T. rubrum with MIC90s of 0.25 and 0.5 μg/mL, respectively.

MIC90: 0.25 μg/mL (T. tonsurans), 0.5 μg/mL (T. rubrum)[1]

Oxiconazole nitrate is the more active compound in tests with T. tonsurans and T. rubrum. Twelve isolates are inhibited by 0.063 μg/mL of oxiconazole; corresponding econazole MICs range from 0.063 (three isolates) to 8 (two isolates) μg/mL. Three isolates have oxiconazole MICs of 16 or 32 μg/mL[1].

The baseline distortion product otoacoustic emission (DPOAE) results of the right ears of all animals tested are normal. Animals in groups I, II, IV and V show no statistically significant change in the DPOAE amplitudes. The rats in the gentamicingroup show a significant decrease[2].

A total of 121 isolates of pathogenic fungi are tested. The three drugs (including Oxiconazole nitrate) are serially diluted in sterile saline. For each test plate, 2 mL of a solution of drug in sterile saline is added to an 18 mL blank of molten agar medium at 50°C and mixed well; the resulting mixtures are then poured into the plates and allowed to solidify. The resulting drug dilution sequences range from 128 to 0.063 μg/mL. Control plates are prepared in a similar manner using 2 mL blanks of sterile saline. The plates are then inoculated using a replicator. Incubation is at 30°C for a minimum of 96 hr. The Minimal Inhibitory Concentration (MIC) is defined as the lowest concentration of drug producing complete inhibition of growth[1].

Fifty adult rats are divided into 5 groups consisting of 10 animals each. Over 14 days, the rats in group I receive 0.1 mL of Oxiconazole nitrate-containing solution drops, group II receives 4% boric acid solution in alcohol drops, and groups III and IV receive gentamicin (40 mg/mL) and saline solutions, respectively. Group V receives no medication. Each solution used is given twice a day[2].
