Abstract
We examined whether chlorpromazine (CPZ) modulates the lethality of doxorubicin (DOX, 12 mg/kg, i.p.) in mice treated with CPZ (6 mg/kg, i.p.) 1 hr before administration of DOX. Pretreatment with CPZ produced: 1) earlier deaths and 2) an increase in the number of deaths, compared to the controls. Potentiation of the bone marrow toxicity of DOX by CPZ was also reflected in the drug lethality towards the animals.
