dc.description.abstract1. Doxorubicin is an anti-cancer drug with well-described effects against a wide range of tumours. However, doxorubicin also exhibits dose-dependent cytotoxicity. the purpose of the present study was to determine whether chronic supplementation of creatine or a mix of vitamins C and E could increase survival and improve plasma parameters 48 h after doxorubicin treatment.2. Rats were divided into four groups: (i) saline (control); (ii) doxorubicin treated; (iii) a creatine (0.2 g/kg per day)-supplemented group; and (iv) a vitamin C (250 mg/kg per day) and E (400 IU/kg per day)-supplemented group. After 30 days supplementation of rats with either creatine or the vitamins, one dose of doxorubicin (15 mg/kg, i.p.) was administered.3. There was no difference in weight loss among the groups until the 3rd day after doxorubicin treatment, but the creatine- and vitamin-supplemented groups lived longer compared with the doxorubicin only treated group (6, 7 and 3 days, respectively). the doxorubicin-treated group lost 13.4% bodyweight over 3 days, whereas the creatine- and vitamin-supplemented groups lost approximately 35% 3 days after the administration of doxorubicin. Doxorubicin treatment resulted in an increase in alanine aminotransferase (ALT; P < 0.05), lactate dehydrogenase (LDH; P < 0.05), urea (P < 0.05) and creatinine (P < 0.05) compared with levels observed in the control group. Conversely, creatine supplementation promoted a partial return to control values for LDH (P < 0.05) and creatinine (P < 0.05), whereas the vitamin mix reversed the changes in ALT (P < 0.05), LDH (P < 0.05), urea (P < 0.05) and creatinine (P < 0.05).4. in conclusion, the results of the present study indicate that the two supplementation protocols decreased the cytotoxic effects of doxorubicin and that a protective effect was more noticeable in animals supplemented with the mixture of vitamins C and E.en
