Mode of Action

Daunorubicin forms a stable complex with DNA and interferes with the nucleic acid synthesis. It is a cell-cycle nonspecific agent, but its cytotoxic effects are mostly marked in the S-phase. It also has immunosuppressant and antibacterial effects.

Precaution

Regular blood count and ECG monitoring; elderly, children. Hepatic or renal impairment may increase risk of toxicity. Pre-existing cardiac disease and previous treatment with doxorubicin. Myocardial toxicity leading to potentially fatal congestive heart failure may occur during therapy or mth to yr after therapy cessation. Incidence of myocardial toxicity increases after total cumulative dose exceeds 400-550 mg/m2 in adults, 300 mg/m2 in children >2 yr, or 10 mg/kg in children <2 yr. Risk of severe myelosuppression leading to infection or haemorrhage. Lactation: excretion in milk unknown/not recommended
