J - Antiinfectives for Systemic Use | Antiinfectives are also classified in the following groups: A01AB Antiinfectives and antiseptics for local oral treatment A02BD Combinations for eradication of Helicobacter pylori A07A Intestinal antiinfectives D01 Antifungals for dermatological use D06 Antibiotics and chemotherapeutics for dermatological use D07C Corticosteroids, combinations with antibiotics D09AA Ointment dressings with antiinfectives D10AF Antiinfectives for treatment of acne G01 Gynecological antiinfectives and antiseptics P Antiparasitic products, insecticides and repellents R02AB Antibiotics S01/ S02/ S03 Eye and ear preparations with antiinfectives Even systemically administered antibacterials and antimycotics may be classified in other groups if their target is exclusively local, e.g. the skin - D01 - Antifungals for dermatological use. Inhaled antiinfectives are classified in J.
| The DDDs for the antiinfectives are as a main rule based on the use in infections of moderate severity. However, some antiinfectives are only used in severe infections and their DDDs are assigned accordingly. The DDDs assigned are based on daily treatment. The duration of the treatment periods is not taken into consideration. For antiinfectives given in a high initially starting dose followed by a lower daily "maintenance" dose, the DDDs are based on the "maintenance" dose if the total duration of the treat-ment course is more than one week. If, however, the treatment course is 7 days or less, the DDDs are assigned according to the average daily dose i.e. the total course dose divided by the number of treatment days (e.g azithromycin).
