Pharmacology (Source, Chemical and Physical Composition) Of Dacarzin 200 mg/vial

Dacarbazine is a non-cell cycle specific antineoplastic agent. The exact mechanism of action by which it exerts cytotoxic effects is still unclear. However, three possible mechanisms have been postulated, including inhibition of DNA synthesis by acting as a purine analog, action as an alkylating agent, and interaction with sulfydryl group in the inhibition of bacterial cell growth.

Drug Interactions of Dacarzin 200 mg/vial

Increased metabolism when used with enzyme inducers (e.g. barbiturates, rifampicin, phenytoin). May potentiate the effect of mercaptopurine, azathioprine, allopurinol. May impair immune response to vaccines. May enhance the effects of methoxsalen due to photosensitisation.

Side Effects of Dacarzin 200 mg/vial

Symptoms of anorexia, nausea and vomiting are the most frequently noted of all toxic reactions. Over 90% of patients are affected with the initial few doses. The vomiting lasts 1 to 12 hours and is incompletely and unpredictably palliated with phenobarbital and/or prochlorperazine. Rarely, intractable nausea and vomiting have necessitated discontinuance of therapy with Dacarbazine for Injection. Rarely, Dacarbazine for Injection has caused diarrhea. Some helpful suggestions include restricting the patient’s oral intake of food for 4 to 6 hours prior to treatment. The rapid toleration of these symptoms suggests that a central nervous system mechanism may be involved, and usually these symptoms subside after the first 1 or 2 days.

Use During Pregnancy and Lactation

Pregnancy Category C. Dacarbazine for Injection has been shown to be teratogenic in rats when given in doses 20 times the human daily dose on day 12 of gestation. Dacarbazine when administered in 10 times the human daily dose to male rats (twice weekly for 9 weeks) did not affect the male libido, although female rats mated to male rats had higher incidence of resorptions than controls. In rabbits, dacarbazine daily dose 7 times the human daily dose given on Days 6 to 15 of gestation resulted in fetal skeletal anomalies. There are no adequate and well controlled studies in pregnant women. Dacarbazine for Injection should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for tumorigenicity shown for Dacarbazine for Injection in animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Precautions And Warnings for Dacarzin 200 mg/vial

Hospitalization is not always necessary but adequate laboratory study capability must be available. Extravasation of the drug subcutaneously during intravenous administration may result in tissue damage and severe pain. Local pain, burning sensation and irritation at the site of injection may be relieved by locally applied hot packs. Carcinogenicity of dacarbazine was studied in rats and mice. Proliferative endocardial lesions, including fibrosarcomas and sarcomas were induced by dacarbazine in rats. In mice, administration of dacarbazine resulted in the induction of angiosarcomas of the spleen.
