ATC Classification System ATC Code L Antineoplastic and immunomodulating agents Classification of drugs comprising preparations used in the treatment of malignant neoplastic diseases, and immunomodulating agents. L ANTINEOPLASTIC AND IMMUNOMODULATING AGENTS This group comprises preparations used in the treatment of malignant neoplastic diseases, and immunomodulating agents. Corticosteroids for systemic use, see H02. L01 ANTINEOPLASTIC AGENTS Combination products are classified in L01XY - Combinations of antineoplastic agents. Detoxifying agents used in connection with high dose treatment of antineoplastic agents are classified in V03AF (e.g. calcium folinate) No DDDs have been established because of highly individualised use and wide dosage ranges. The doses used vary substantially because of various types and severity of neoplastic diseases, and also because of the extensive use of combination therapy. The consumption of the antineoplastic agents is in some countries measured in grams. This is recommended as a method to be used internationally for these particular agents. L02 ENDOCRINE THERAPY Estrogens and progestogens used specifically in the treatment of neoplastic diseases are classified in this group. This means that some strengths may be classified in this group, while remaining strengths are classified in G03 - Sex hormones and modulators of the genital system. The DDDs are based on the treatment of cancer (breast-, endometrial, and prostatic). L03 IMMUNOSTIMULANTS Immunosuppressants, see L04A.
