LOPROX® Lotion (ciclopirox lotion) has a pH of 7.
LOPROX® Lotion (ciclopirox lotion) is indicated for the topical treatment of the following dermal infections: tinea pedis, tinea cruris and tinea corporis due to Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, and Microsporum canis; cutaneous candidiasis (moniliasis) due to Candida albicans; and tinea (pityriasis) versicolor due to Malassezia furfur.
Gently massage LOPROX® Lotion (ciclopirox lotion) into the affected and surrounding skin areas twice daily, in the morning and evening. Clinical improvement with relief of pruritus and other symptoms usually occurs within the first week of treatment. If a patient shows no clinical improvement after four weeks of treatment with LOPROX® Lotion (ciclopirox lotion) the diagnosis should be redetermined. Patients with tinea versicolor usually exhibit clinical and mycological clearing after two weeks of treatment.
Loprox® Lotion (ciclopirox) 0.77% is supplied in 30 ml bottles (NDC 99207-008-30), 60 ml bottles (NDC 99207-008-60).
Bottle space provided to allow for vigorous shaking before each use.
Store between 5º - 25ºC (41º - 77ºF).

In the controlled clinical trial with 89 patients using LOPROX® Lotion (ciclopirox lotion) and 89 patients using the vehicle, the incidence of adverse reactions was low. Those considered possibly related to treatment or occurring in more than one patient were pruritus, which occurred in two patients using ciclopirox lotion and one patient using the lotion vehicle, and burning, which occurred in one patient using ciclopirox lotion.

LOPROX® Lotion (ciclopirox lotion) is not for ophthalmic use.
Keep out of reach of children.
If a reaction suggesting sensitivity or chemical irritation should occur with the use of LOPROX® Lotion (ciclopirox lotion) , treatment should be discontinued and appropriate therapy instituted.
A carcinogenicity study in female mice dosed cutaneously twice per week for 50 weeks followed by a 6-month drug-free observation period prior to necropsy revealed no evidence of tumors at the application site. The following in vitro and in vivo genotoxicity tests have been conducted with ciclopirox olamine: studies to evaluate gene mutation in the Ames Salmonella/Mammalian Microsome Assay (negative) and Yeast Saccharomyces Cerevisiae Assay (negative) and studies to evaluate chromosome aberrations in vivo in the Mouse Dominant Lethal Assay and in the Mouse Micronucleus Assay at 500 mg/kg (negative). The following battery of in vitro genotoxicity tests were conducted with ciclopirox: a chromosome aberration assay in V79 Chinese Hamster Cells, with and without metabolic activation (positive); a gene mutation assay in the HGPRT - test with V79 Chinese Hamster Cells (negative); and a primary DNA damage assay (i.e., unscheduled DNA Synthesis Assay in A549 Human Cells (negative)). An in vitroCell Transformation Assay in BALB/C3T3 Cells was negative for cell transformation. In an in vivo Chinese Hamster Bone Marrow Cytogenetic Assay, ciclopirox was negative for chromosome aberrations at 5000 mg/kg.
Reproduction studies have been performed in the mouse, rat, rabbit, and monkey, via various routes of administration, at doses 10 times or more the topical human dose and have revealed no significant evidence of impaired fertility or harm to the fetus due to ciclopirox. There are, however, no adequate or well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
It is not known whether this drug is excreted in human milk. Caution should be exercised when LOPROX® Lotion (ciclopirox lotion) is administered to a nursing woman.
Safety and effectiveness in pediatric patients below the age of 10 years have not been established.
No information provided.
LOPROX® Lotion (ciclopirox lotion) is contraindicated in individuals who have shown hypersensitivity to any of its components.
Ciclopirox is a broad-spectrum, antifungal agent that inhibits the growth of pathogenic dermatophytes, yeasts, and Malassezia furfur. Ciclopirox exhibits fungicidal activity in vitro against isolates of Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis, and Candida albicans.
Pharmacokinetic studies in men with radiolabeled ciclopirox solution in polyethylene glycol 400 showed an average of 1.3% absorption of the dose when it was applied topically to 750 cm2 on the back followed by occlusion for 6 hours. The biological half-life was 1.7 hours and excretion occurred via the kidney. Two days after application only 0.01% of the dose applied could be found in the urine. Fecal excretion was negligible. Autoradiographic studies with human cadaver skin showed that ciclopirox penetrates into the hair and through the epidermis and hair follicles into the sebaceous glands and dermis, while a portion of the drug remains in the stratum corneum.
In vitro penetration studies in frozen or fresh excised human cadaver and pig skin indicated that the penetration of LOPROX® Lotion is equivalent to that of Loprox® Cream (ciclopirox olamine) 0.77%. Therapeutic equivalence of cream and lotion formulations also was indicated by studies of experimentally induced guinea pig and human trichophytosis.
