Finacea Foam
(Azelaic Acid)Finacea Foam Prescribing Information
FINACEA Foam, 15% is indicated for topical treatment of the inflammatory papules and pustules of mild to moderate rosacea.
- Shake well before use.
- Cleanse affected area(s) using only very mild soaps or soapless cleansing lotion and pat dry with a soft towel before application of FINACEA Foam.
- Apply FINACEA Foam twice daily (morning and evening) to the entire facial area (cheeks, chin, forehead, and nose). For a single application, dispense the smallest amount of foam necessary to adequately cover the affected area(s) with a thin layer.
- Use FINACEA Foam continuously over 12 weeks.
- Wash hands immediately following application of FINACEA Foam.
- Cosmetics may be applied after the application of FINACEA Foam has dried.
- Reassess the diagnosis if no improvement is observed upon completing 12 weeks of therapy.
- Avoid the use of occlusive dressings or wrappings.
- Instruct patients to avoid use of alcoholic cleansers, tinctures and astringents, abrasives and peeling agents.
- For topical use.
- Not for oral, ophthalmic or intravaginal use.
Each gram of FINACEA (azelaic acid) Foam contains 0.15 g of azelaic acid (15% w/w) in a white to off-white foam.
Azelaic acid is minimally absorbed systemically following topical route of administration, and maternal use is not expected to result in fetal exposure to the drug
12.3 PharmacokineticsPharmacokinetics of azelaic acid and its metabolite pimelic acid was assessed in 21 adult subjects with moderate papulopustular rosacea with a minimum of 15 and no more than 50 inflammatory lesions (papules and/or pustules). Endogenous plasma concentrations of azelaic acid (range <1-105 ng/mL) and pimelic acid (range 0.69-27 ng/mL) were measured over various time points over 2 days prior to treatment initiation. The endogenous plasma concentrations varied widely across subjects and the mean ± SD values of endogenous azelaic acid plasma concentrations ranged between 4.5 ± 2.4 ng/mL and 14.6 ± 5.6 ng/mL and pimelic acid plasma concentrations ranged between 2.2 ± 1.1 ng/mL and 3.7 ± 3.1 ng/mL.
Following topical dermal applications of a mean dose of 0.94 g of FINACEA Foam (141 mg azelaic acid) twice daily for 7 consecutive days, systemic concentrations of azelaic acid were at steady state by Day 5. On Day 7, a wide range of maximum azelaic acid (22.2 to 90.1 ng/mL) and pimelic acid (2.3-16.9 ng/mL) plasma concentrations (Cmax) was also observed after treatment with FINACEA Foam. The mean ± SD Cmaxfor azelaic acid and pimelic acid were 51.8 ± 18.5 ng/mL and 5.0 ± 3.0 ng/mL, respectively. The mean ± SD systemic exposure of azelaic acid and pimelic acid within a dosing interval (AUC0-12h) were 442.0 ± 177.6 ng.h/mL and 43.4 ± 15.4 ng.h/mL, respectively.
Azelaic acid is mainly excreted unchanged in the urine, but undergoes some ß-oxidation to shorter chain dicarboxylic acids.
In animal reproduction studies, embryofetal toxicity was noted when azelaic acid was administered orally during the period of organogenesis at doses 162, 19, and 65 times the maximum recommended human dose (MRHD) in rats, rabbits, and monkeys, respectively. Maternal toxicity was noted at these doses but no malformations were observed in these embryofetal developmental studies (
Dermal embryofetal developmental toxicology studies have not been performed with azelaic acid, 15% foam. Oral embryofetal developmental studies were conducted with azelaic acid in rats, rabbits, and cynomolgus monkeys. Azelaic acid was administered during the period of organogenesis in all three animal species. Embryotoxicity was observed in rats, rabbits, and monkeys at oral doses of azelaic acid that generated some maternal toxicity. Embryotoxicity was observed in rats given 2500 mg/kg/day [162 times the MRHD based on body surface area (BSA) comparison], rabbits given 150 or 500 mg/kg/day (19 or 65 times the MRHD based on BSA comparison) and cynomolgus monkeys given 500 mg/kg/day (65 times the MRHD based on BSA comparison) azelaic acid. No malformations were observed in the oral embryofetal developmental studies conducted in rats, rabbits and cynomolgus monkeys.
An oral peri- and post-natal developmental study was conducted in rats. Azelaic acid was administered from gestational day 15 through day 21 postpartum up to a dose level of 2500 mg/kg/day. Embryotoxicity was observed in rats at an oral dose of 2500 mg/kg/day (162 times the MRHD based on BSA comparison) that generated some maternal toxicity. In addition, slight disturbances in the post-natal development of fetuses was noted in rats at oral doses that generated some maternal toxicity (500 and 2500 mg/kg/day; 32 and 162 times the MRHD based on BSA comparison). No effects on sexual maturation of the fetuses were noted in this study.
The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
None.
- Hypopigmentation:Isolated cases of hypopigmentation occurred after azelaic acid use. Monitor patients with dark complexion for early signs of hypopigmentation ()
5.1 HypopigmentationThere have been reports of hypopigmentation after use of azelaic acid. Because azelaic acid has not been well studied in patients with dark complexion, monitor these patients for early signs of hypopigmentation.
- Eye and Mucous Membrane Irritation:Azelaic acid has been reported to cause irritation of the eyes. Avoid contact with the eyes and mucous membranes. ()
5.2 Eye and Mucous Membranes IrritationAzelaic acid has been reported to cause irritation of the eyes. Avoid contact with the eyes, mouth and other mucous membranes. If FINACEA Foam does come in contact with the eyes, wash the eyes with large amounts of water and consult a physician if eye irritation persists.
- Flammability:Contents are flammable. Instruct the patient to avoid fire, flame, and smoking during and immediately following application. ()
5.3 FlammabilityThe propellant in FINACEA Foam is flammable. Instruct the patient to avoid fire, flame, and smoking during and immediately following application. Do not puncture and/or incinerate the containers. Do not expose containers to heat and/or store at temperatures above 120°F (49°C).
