ফার্মাকোলজি

Decitabine is believed to exert its antineoplastic effects after phosphorylation and direct incorporation into DNA and inhibition of DNA methyltransferase, causing hypomethylation of DNA and cellular differentiation or apoptosis. Decitabine inhibits DNA methylation in vitro, which is achieved at concentrations that do not cause major suppression of DNA synthesis. Decitabine-induced hypomethylation in neoplastic cells may restore normal function to genes that are critical for the control of cellular differentiation and proliferation. In rapidly dividing cells, the cytotoxicity of decitabine may also be attributed to the formation of covalent adducts between DNA methyltransferase and decitabine incorporated into DNA. Non-proliferating cells are relatively insensitive to decitabine.

A complete or partial response may take longer than 4 cycles. Delay and reduce dose for hematologic toxicityFive Day Regimen: Administer DACOGEN at a dose of 20 mg/m2 by continuous intravenous infusion over 1 hour daily for 5 days. Delay and reduce dose for hematologic toxicity (see Dose Modifications for Toxicity).

পার্শ্বপ্রতিক্রিয়া

Most common adverse reactions (>50%) are neutropenia, thrombocytopenia, anemia, and pyrexia.

সতর্কতা

Neutropenia and thrombocytopenia: Perform complete blood counts and platelet counts.Embryo-fetal Toxicity: Can cause fetal harm. Advise patients of reproductive potential of the potential risk to a fetus and to use effective contraception.

গর্ভাবস্থায় ও স্তন্যদানকালে ব্যবহার

Based on findings from human data, animal studies, and the mechanism of action, Decitabine can cause fetal harm when administered to a pregnant woman. Advise not to breastfeed. There are no data on the presence of decitabine or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production.

সংরক্ষণ

Keep below 25°C temperature, away from light & moisture. Keep out of the reach of children.
