Sonazole Tube

Uses

Sonazole Tube cream 2% is an azole antifungal used for the topical treatment of interdigital tinea pedis in immunocompetent patients 12 years of age and older, caused by: Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum.

Sonazole Tube is also used to associated treatment for these conditions: Interdigital Tinea Pedis, Skin Mycoses, Vulvovaginal Candidiasis

How Sonazole Tube works

Sonazole Tube interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol. As ergosterol is an essential component of the fungal cell membrane, inhibition of its synthesis results in increased cellular permeability causing leakage of cellular contents. Sonazole Tube may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms, inhibit purine uptake, and impair triglyceride and/or phospholipid biosynthesis.

Dosage

Sonazole Tube dosage

In the treatment of interdigital tinea pedis, Sonazole Tube cream, 2%, should be applied twice daily for 4 weeks. Sufficient amount of Sonazole Tube cream, 2%, should be applied to cover both the affected areas between the toes and the immediately surrounding healthy skin of patients with interdigital tinea pedis. Not for ophthalmic, oral, or intravaginal use.

Side Effects

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug, and may not reflect the rates observed in practice.

In clinical trials, cutaneous adverse events occurred in 7 of 297 (2%) subjects (2 of them severe) receiving Sonazole Tube cream, 2%, and in 7 of 291 (2%) subjects (2 of them severe) receiving vehicle. These reported cutaneous adverse events included contact dermatitis, dry skin, burning skin, application site skin tenderness.

In a dermal sensitization trial, 8 of 202 evaluable subjects tested with Sonazole Tube cream, 2%, and 4 of 202 evaluable subjects tested with vehicle, exhibited a slight erythematous reaction in the challenge phase. There was no evidence of cumulative irritation or contact sensitization in a repeated insult patch test involving 202 healthy volunteers.

Precaution

If irritation develops, treatment should be discontinued and appropriate therapy instituted. Physicians should exercise caution when prescribing Sonazole Tube cream, 2%, to patients known to be sensitive to azole antifungals, since crossreactivity may occur.
