Daunocin-20mg Inj.

Side Effects of Daunocin-20mg Inj.

GI disturbances; stomatitis; alopoecia and dermatological reactions. Extravasation of daunorubicin may cause severe local tissue necrosis damaging surrounding muscles, tendons and nerves. IV infusion, back pain, flushing and chest tightness. Potentially Fatal: Bone marrow suppression, cardiac toxicity, cardiomyopathy and congestive heart failure.

Drug Interactions

Increased risk of cardiotoxicity when used with cyclophosphamide. Increased risk of hepatic toxicity when used with hepatotoxic drugs e.g. high-dose methotrexate. Potentially Fatal: Immunisation with live vaccines is not recommended. Concurrent radiation may lead to increased radiation reaction.

Contraindications

Heart failure. Pregnancy, lactation.

Mechanism 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. Distribution: Body tissues; crosses the placenta; enters breast milk. Metabolism: Hepatic; converted to daunorubicinol. Excretion: Urine (as active form). Elimination half-life: 18.5 hr (daunorubicin), 26.7 hr (active metabolite).

Special Precautions

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.
