title: [Effect of calcium gluconate on the toxicity and antitumor of doxorubicin in mice].
abstract: The effect of calcium gluconate on the toxicity and specific activity of the anthracycline antibiotic doxorubicin was studied on mice with transplanted hemoblastosis La or plasmocytoma MOPS-406. In both cases after the animal exposure to nontoxic therapeutic doses of doxorubicin no influence of calcium gluconate on the antibiotic antitumor activity was observed. When doxorubicin was used in toxic (and even lethal) doses the antitoxic effect of calcium gluconate and an increase of the antibiotic therapeutic activity were stated. The combination of calcium gluconate and doxorubicin made it possible to significantly increase the maximum therapeutic effect of doxorubicin (higher levels of the animal survival and some cures) and to widen the ranges of the drug therapeutic doses at the account of decreasing the toxicity of the antibiotic and increasing its dose. The results suggested that the antitoxic modifier calcium gluconate could be used for increasing anticancer efficacy of doxorubicin which is given now at the total dose limit of 550 mg/m2 even in cases with preserved tumor sensitivity to the drug.
