What Defines ATC Class D07AA?
ATC Classification System Overview:
| Level | Code | Description |
|---|---|---|
| 1 | D | Dermatologicals |
| 2 | D07 | Corticosteroids and other anti-inflammatory agents, skin-atoms, and keratolytics |
| 3 | D07AA | Corticosteroids, weak (group I) |
Characteristics of D07AA:
- Comprises low-potency corticosteroids, such as hydrocortisone and hydrocortisone derivatives.
- Used primarily in sensitive skin areas to minimize systemic absorption.
- Focus on topical formulations, including creams, ointments, gels, and lotions.
What Are the Market Drivers for D07AA Corticosteroids?
Increasing Dermatological Disease Incidence
- The global burden of eczema affects approximately 10-20% of children and 3-10% of adults [1].
- Psoriasis prevalence ranges between 0.5-4% worldwide [2].
- Rising pollutants and lifestyle factors contribute to increasing skin conditions.
Preference for Topical and Low-Potency Agents
- Patients and clinicians favor low-potency corticosteroids because they carry a lower risk of side effects compared to high-potency options.
- Regulatory guidelines recommend weak corticosteroids as first-line therapy for delicate areas (face, intertriginous zones).
