Anatomical Therapeutic Chemical (ATC) classification – Dermatologicals (Other dermatologicals)
Overview
ATC code D11 designates the subgroup “Other dermatologicals” within the World Health Organization’s Anatomical Therapeutic Chemical (ATC) Classification System. The ATC system groups drugs and medical products according to the organ or system on which they act and their therapeutic, pharmacological, and chemical properties.
The D‑series covers Dermatologicals, i.e., substances intended for topical, local, or systemic use on the skin. Within this series, the D11 subgroup collects dermatological preparations that do not belong to the more specific therapeutic categories (e.g., antifungals, corticosteroids, anti‑acne agents).
Position in the ATC Hierarchy
| Level | Code | Description |
|---|---|---|
| 1 – Anatomical main group | D | Dermatologicals |
| 2 – Therapeutic subgroup | D11 | Other dermatologicals |
| 3 – Pharmacological subgroup | varies (e.g., D11AA, D11AB, …) | |
| 4 – Chemical subgroup | varies | |
| 5 – Chemical substance | specific active ingredient |
Note: The third‑level codes (e.g., D11AA, D11AB, D11AC, etc.) further split the “Other dermatologicals” category into pharmacologically distinct groups such as antibiotics, antiseptics, keratolytics, and other agents.
Typical Pharmacological Sub‑groups (selected)
| ATC code | Pharmacological theme | Representative agents |
|---|---|---|
| D11AA | Antibacterial preparations for skin | Mupirocin, fusidic acid |
| D11AB | Antiseptic preparations for skin | Chlorhexidine, povidone‑iodine |
| D11AC | Keratolytic agents | Salicylic acid, urea |
| D11AD | Anti‑pruritic preparations | Capsaicin, menthol |
| D11AE | Other topical agents (e.g., sunscreens, astringents) | Zinc oxide, aluminum chloride |
The exact composition of sub‑groups may evolve as new agents are approved.
Clinical Use
Products classified under D11 are employed for a broad array of cutaneous conditions, including:
- Bacterial skin infections – topical antibiotics (e.g., impetigo, minor wounds).
- Disinfection and antisepsis – preparation for surgical sites or minor cuts.
- Hyperkeratosis and callus removal – keratolytic agents in podiatry or dermatology.
- Itch relief – topical antipruritics for eczema, insect bites, or allergic dermatitis.
- Adjunctive skin care – barrier protectants, astringents, and sunscreen agents that do not fit other ATC categories.
Because the D11 group gathers “miscellaneous” dermatological products, it provides a flexible classification for agents that are either multifunctional or unique in their mechanism of action.
Examples of Medicines (selected)
| Product (trade name) | Active ingredient(s) | ATC code |
|---|---|---|
| Bactroban | Mupirocin 2 % (ointment) | D11AA01 |
| Fucidin | Fusidic acid 2 % (cream) | D11AA04 |
| Savlon | Chlorhexidine 0.5 % (solution) | D11AB02 |
| Polysporin | Polymyxin B + Bacitracin (ointment) | D11AA03 |
| Salicylanilide | Salicylanilide 5 % (cream) | D11AC01 |
| Zincox | Zinc oxide 20 % (paste) | D11AE01 |
| Capzasin | Capsaicin 0.025 % (gel) | D11AD01 |
ATC codes are illustrative; commercial products may be listed under slightly different sub‑codes depending on formulation.
