Most of the drugs in this group are preparations for topical use. Some few preparations for systemic use with clear dermatological applications, e.g. griseofulvin (antimycotic), retinoids (for treatment of acne) and psoralens and retinoids (for treatment of psoriasis) are classified in this group.

As a main rule, all topical corticosteroid preparations should be classified in this group. There are, however, some few exceptions:
Combinations of corticosteroids and antiinfectives for gynaecological use, see G01B.
Corticosteroids for local oral treatment, see A01AC.
Corticosteroids in combination with antifungals are classified in D01A.
Anti-acne preparations, see D10A.
Antihemorrhoidals with corticosteroids, see C05AA.
Corticosteroids for ophthalmological or otological use, see S - Sensory organs.

This group comprises most other combined corticosteroid preparations for dermatological use, e.g. combinations with coal tar, carbamide and salicylic acid. Salicylic acid is regarded as a keratolytic agent.
Preparations with salicylic acid and antiseptics are classified in this group, as salicylic acid is regarded as being more important than the antiseptics for the therapeutic use of these products (psoriasis, seborrhea).
The group is subdivided according to clinical potency, see D07A.
Exceptions, see D07.
Corticosteroids in combination with antifungals are classified in D01A.
