Drugs in ATC Class: A09AB - Acid preparations
Market Dynamics and Patent Landscape for ATC Class A09AB – Acid Preparations
What is the scope and application of ATC Class A09AB?
ATC Class A09AB encompasses acid preparations, primarily including formulations containing acids such as salicylic, lactic, and sulfuric acids. These are used mainly in dermatology and personal care. Applications cover treatment of skin conditions like acne, psoriasis, and seborrheic dermatitis. The class also includes cosmetic products aimed at exfoliation and pH regulation.
How large is the market for acid preparations?
The global acid preparations market, estimated at USD 2.3 billion in 2022, is forecast to reach USD 3.1 billion by 2030. Compound annual growth rate (CAGR) is approximately 3.7% (Fortune Business Insights, 2022). Growth drivers include increasing demand for topical dermatological treatments, rising skincare awareness, and expansion in emerging markets.
Key regional markets:
| Region | Market Size (2022, USD billion) | CAGR (2023-2030) | Main Factors |
|---|---|---|---|
| North America | 0.85 | 3.2% | High skincare product adoption |
| Europe | 0.65 | 3.5% | Aging population, regulatory frameworks |
| Asia-Pacific | 0.55 | 4.5% | Growing dermatology clinics, urbanization |
| Latin America | 0.20 | 3.0% | Increased cosmetic awareness |
What are the key market drivers and challenges?
Drivers:
- Dermatology Treatment Expansion: Rise in skin conditions due to pollution and lifestyle changes fuels demand for acid-based treatments.
- Cosmetic Industry Growth: acids like alpha hydroxy acids (AHAs) gain popularity for anti-aging and exfoliation.
- Increasing Awareness: Consumers seek over-the-counter and prescription products addressing skin health.
Challenges:
- Regulatory Constraints: Stringent regulations on certain acids (e.g., hydroxy acids) for concentration and labeling.
- Adverse Effects: Skin irritation limits usage in some demographics.
- Market Saturation: Mature markets show slowing growth, with innovation becoming pivotal.

What patent expiry trends influence the market?
Most critical patents filed between 2005 and 2015 will expire between 2025 and 2030. Patent expirations open opportunities for generic and biosimilar entrants, especially in mature markets.
| Patent Expiry Year | Number of Patents Expiring | Implication |
|---|---|---|
| 2025 | 20 | Entry of generics in North America and Europe |
| 2028 | 35 | Increased competition in Asian markets |
What are the regulatory considerations?
Regulatory frameworks across jurisdictions influence formulation approvals:
- US: The FDA classifies acids as active ingredients under OTC monographs or requires NDA if used in novel formulations.
- EU: Regulations on cosmetic acids impose maximum concentration limits and labeling requirements.
- Asia-Pacific: Regulations vary; India’s ISO standards and Chinese SFDA policies set standards for cosmetic actives.
Compliance with these regulations determines patenting strategy, especially for formulations with novel delivery systems.
