Cytotoxic

(Science: pharmacology) chemicals that are directly toxic to cells, preventing their reproduction or growth. Cytotoxic agents can, as a side effect, damage healthy, noncancerous tissues or organs which have a high proportion of actively dividing cells, for example, bone marrow, hair follicles. These side effects limit the amount and frequency of drug administration.
