⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Do not exceed an application area of 60 cm 2 . Do not use more than 6 grams of AMELUZ (3 tubes) at one time ( 2.2 ). Retreat lesions that have not completely resolved 3 months after the initial treatment ( 2.2 ).
2.1Important Administration Information AMELUZ, in conjunction with lesion preparation, is only to be administered by a health care provider. AMELUZ is for topical use only. Not for ophthalmic, oral, or intravaginal use.
Treat single lesions or an entire field affected by multiple lesions with AMELUZ, in combination with red light photodynamic therapy (PDT). PDT requires administration of both AMELUZ and BF-RhodoLED or RhodoLED XL light. Refer to BF-RhodoLED or RhodoLED XL user manual for detailed lamp safety and operating instructions.
Adhere to all safety instructions for both patient and medical personnel while conducting the PDT.
2.2Recommended Dosage Apply an approximately 1-mm thick layer of AMELUZ to skin lesion(s). Cover individual lesions or the entire AK-field with AMELUZ. Include approximately 5 mm of the surrounding skin. Do not exceed an application area of 60 cm 2 . Do not use more than 6 grams of AMELUZ (3 tubes) at one time. Retreat lesions that have not completely resolved after 3 months after the initial treatment.
2.3Administration Instructions PDT is a multi-stage process: Step 1. Preparation of Lesions Before applying AMELUZ, carefully wipe all lesions with an ethanol or isopropanol-soaked cotton pad to ensure degreasing of the skin. Figure 1A: Degreasing the skin Thereafter, remove any scaling and crusts and gently roughen all lesion surfaces, taking care to avoid bleeding.
Figure 1B: Removal of scales and crusts Step 2. Application of AMELUZ Apply AMELUZ using glove protected fingertips or a spatula. Use sufficient amount of gel to cover individual lesions or the entire field: Lesion-directed treatment: Apply gel approximately 1 mm thick to one or more individual AK lesions and include approximately 5 mm of the surrounding healthy skin.
Field-directed treatment: Apply gel approximately 1 mm thick to the treatment field. Apply gel to the lesions and the skin in-between the lesions. Additionally, cover approximately 5 mm of the surrounding healthy area.
Do not exceed an application area of 60 cm 2 and do not use more than 6 grams of AMELUZ (3 tubes) at one time. The gel can be applied to healthy skin around the lesions. Avoid application near mucous membranes such as the eyes, nostrils, mouth, and ears (keep a distance of 1 cm from these areas).
In case of accidental contact with mucous membranes, thoroughly rinse with water [ see Warnings and Precautions (5.7) ]. Allow the gel to dry for approximately 10 minutes before applying occlusive dressing. Figure 2: Drug application Step 3.

Most common adverse reactions (≥10%) were application site erythema, pain/burning, irritation, edema, pruritus, exfoliation, scab, induration, and vesicles ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Biofrontera Inc. at 1-844-829-7434 or FDA at 1-800-332-1088 or www.fda.gov/medwatch .
6.1Clinical Trial Experience 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. The clinical program for AMELUZ included three double-blind and placebo-controlled phase 3 trials (Trials 1, 2, and 3), enrolling a total of 299 subjects that were treated with narrow band light. Trial subjects were adults greater than or equal to 49 years of age, and the majority had Fitzpatrick skin type I, II, or III.
No subjects had Fitzpatrick skin type V or VI. Approximately 86% of subjects were male, and all subjects were White. For all three phase 3 trials, the enrolled subjects had mild to moderate AKs (Olsen grade 1 and 2) with 4 to 8 lesions on the face and scalp.
Overall, 212 AMELUZ-treated subjects (n=32, n=55, and n=125) and 87 subjects receiving placebo (n=16, n=32, n=39) were illuminated with BF-RhodoLED or similar narrow spectrum lamps. For these trials, the maximal dose was one tube of AMELUZ (2 g) and the size of the application area was up to 20 cm 2 . Local skin reactions at the application site were observed in about 99.5% of subjects treated with AMELUZ and narrow spectrum lamps.
The most frequent adverse reactions during and after PDT were application site erythema, pain, burning, irritation, edema, pruritus, exfoliation, scab, induration, and vesicles. Most adverse reactions occurred during illumination or shortly afterwards, were generally of mild or moderate intensity, and lasted for 1 to 4 days in most cases; in some cases, however, they persisted for 1 to 2 weeks or even longer. Severe pain/burning occurred in up to 30% of subjects.
In one case, the adverse reactions required interruption or discontinuation of the illumination. Table 1 presents the incidence of common (≥1%, <10%) and very common (≥10%) adverse reactions at the application site in randomized, multicenter trials which evaluated a maximal dose of one tube of AMELUZ (2 g) and an application area up to 20 cm 2 .

👥 Use in Specific Populations ▾
8. USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available data on AMELUZ use in pregnant women to inform a drug associated risk. Animal reproduction studies were not conducted with aminolevulinic acid. Systemic absorption of aminolevulinic acid in humans is negligible following topical administration of AMELUZ under maximal clinical use conditions [see Clinical Pharmacology (12.3) ] .
It is not expected that maternal use of AMELUZ will result in fetal exposure to the drug. The background risk of major birth defects and miscarriage for the indicated population are unknown. 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.
8.2Lactation Risk Summary No data are available regarding the presence of aminolevulinic acid in human milk, the effects of aminolevulinic acid on the breastfed infant or on milk production. However, breastfeeding is not expected to result in exposure of the child to the drug due to the negligible systemic absorption of aminolevulinic acid in humans following topical administration of AMELUZ under maximal clinical use conditions [see Clinical Pharmacology (12.3) ] . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for AMELUZ and any potential adverse effects on the breastfeeding child from AMELUZ or from the underlying maternal condition.
8.4Pediatric Use Safety and effectiveness in pediatric patients below the age of 18 have not been established. AK is not a condition generally seen in the pediatric population.
8.5Geriatric Use Of the 384 subjects exposed to AMELUZ in randomized, multicenter clinical trials, 83% (318/384) of the subjects were 65 years old and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.

🧬 Clinical Pharmacology ▾
12. CLINICAL PHARMACOLOGY
12.1Mechanism of Action Photoactivation following topical application of AMELUZ occurs when aminolevulinic acid (prodrug) is metabolized to protoporphyrin IX (PpIX), a photoactive compound which accumulates in the skin. When exposed to red light of a suitable wavelength and energy, PpIX is activated resulting in an excited state of porphyrin molecules. In the presence of oxygen, reactive oxygen species are formed which causes damage to cellular components, and eventually destroys the cells.
AMELUZ photodynamic therapy of AK lesions utilizes photoactivation of topically applied AMELUZ resulting from BF-RhodoLED or RhodoLED XL illumination, which provides a red light of narrow spectrum and a light dose of approximately 37 J/cm 2 .
12.2Pharmacodynamics The pharmacodynamics of AMELUZ in the treatment of actinic keratosis are unknown.
12.3Pharmacokinetics Aminolevulinic acid acts as a prodrug to the photoactive metabolite protoporphyrin IX (PpIX). Pharmacokinetics (PK) of aminolevulinic acid and PpIX were evaluated in two trials: In the first trial, a single dose of one entire tube of AMELUZ (2 grams) was applied under occlusion for 3 hours followed by PDT to a total area of 20 cm 2 in 12 adult subjects with mild to moderate AK with at least 10 AK lesions on the face or forehead. The mean ± SD baseline plasma aminolevulinic acid concentration was 20.16 ± 16.53 ng/mL.
In most subjects, an up to 2.5-fold increase of aminolevulinic acid plasma concentrations was observed during the first 3 hours after AMELUZ application. The mean ± SD area under the concentration time curve (AUC 0-t ) and maximum concentration (C max ) for baseline corrected aminolevulinic acid (n=12) were 142.83 ± 75.50 ng·h/mL and 27.19 ± 20.02 ng/mL, respectively. The median T max (time at which C max occurred) was 3 hours.
The mean ± SD baseline plasma PpIX concentration was 3.27 ± 2.40 ng/mL (n=12). The majority (about 55%) of the PpIX concentrations were below the limit of quantification (LOQ = 1 ng/mL) and baseline corrected values were negative in all subjects except for one. The baseline corrected AUC 0-t and C max in the single subject was 0.07 ng·h/mL and 0.29 ng/mL, respectively.
In the second trial, a single dose of three entire tubes of AMELUZ (6 grams) was applied under occlusion for 3 hours followed by PDT to a total area of 60 cm 2 in 16 adult subjects with mild to severe AK with at least 12 AK lesions on the face and scalp. The mean ± SD baseline plasma aminolevulinic acid concentration was 13.53 ± 1.58 ng/mL. In most subjects, an up to 2.5-fold increase of aminolevulinic acid plasma concentrations was observed during the first 3 hours after AMELUZ application.
The mean ± SD area under the concentration time curve (AUC 0-t ) and maximum concentration (C max ) for baseline corrected aminolevulinic acid (n=16) were 134.24 ± 87.97 ng·h/mL and 33.85 ± 21.85 ng/mL, respectively. The median T max (time at which C max occurred) was 3 hours. The mean ± SD baseline plasma PpIX concentration was 1.93 ± 0.42 ng/mL (n=15).
The mean ± SD baseline corrected C max of PpIX was 0.67 ± 0.78 ng/mL (n=13) with a median T max of 4 hours. The baseline corrected PpIX concentrations in 14 of 15 subjects were < 1 ng/mL.

AMELUZ photodynamic therapy of AK lesions utilizes photoactivation of topically applied AMELUZ resulting from BF-RhodoLED or RhodoLED XL illumination, which provides a red light of narrow spectrum and a light dose of approximately 37 J/cm 2 .
