Doxorex 10mg Injection

About

Doxorubicin is a potent anthracycline cytotoxic antibiotic extensively utilized in chemotherapy for a wide array of malignancies. Its primary mechanism of action involves intercalation into DNA, which disrupts macromolecular biosynthesis, and the generation of highly reactive free radicals, leading to significant DNA damage and subsequent programmed cell death, particularly in rapidly proliferating cancer cells. Furthermore, doxorubicin inhibits topoisomerase II, an enzyme crucial for DNA unwinding and replication, thereby preventing cellular division. This multifaceted approach makes doxorubicin highly effective against a broad spectrum of solid tumors, such as breast and ovarian cancers, and various hematological malignancies, including lymphomas and leukemias. It serves as a cornerstone in numerous cancer treatment regimens, often used in combination with other agents. However, due to its powerful cytotoxic effects, careful clinical monitoring is imperative during administration to manage potential adverse reactions, with particular attention to its dose-dependent cardiotoxicity.

Safety Measures

• Alcohol - Avoid alcohol during doxorubicin treatment as it may exacerbate gastrointestinal side effects and potentially increase liver strain.
• Pregnancy - Doxorubicin is highly teratogenic and contraindicated in pregnancy due to severe fetal harm. Effective contraception is essential during treatment.
• Breastfeeding - Breastfeeding is contraindicated during doxorubicin therapy as the drug is excreted in breast milk and can cause serious adverse effects in the infant.
• Liver - Use with extreme caution in patients with hepatic impairment; dose adjustments are often necessary due to impaired drug metabolism and increased toxicity risk.
• Kidney - Generally, no major dose adjustments are needed for mild to moderate renal impairment, but caution is advised, and monitoring is recommended.
• Lung - While not a primary lung toxicant, patients with pre-existing lung conditions should be monitored for any respiratory distress, especially if combined with other lung-toxic agents.
