What Ledaga is and what it is used for
Ledaga contains the active substance chloromethane. It is an anti-cancer drug used on the skin to treat cutaneous T-cell lymphoma of the mycosis fungoides type (CTCL of the MF type).
MTC-type CTCL is a disease in which certain cells in the body’s immune system, the so-called T lymphocytes, become cancer cells and attack the skin. Chloromethine is a type of anti-cancer drug called an “alkylating agent”. It binds to DNA in dividing cells, such as cancer cells, which prevents them from multiplying and growing.
Ledaga is only for use on adults.
