Doxotero 10mg Injection

About

Doxorubicin is an anthracycline cytotoxic antibiotic widely used in the treatment of various cancers. It exerts its antineoplastic effects primarily through several intricate mechanisms. These include intercalation into DNA, which disrupts the DNA structure and function, inhibition of topoisomerase II, an enzyme crucial for DNA replication and repair, and the generation of reactive oxygen species (free radicals) that cause oxidative damage to cellular components. These combined actions lead to significant DNA damage, inhibition of both DNA and RNA synthesis, and ultimately, programmed cell death (apoptosis) in rapidly dividing cancer cells. Administered intravenously, doxorubicin is extensively metabolized in the liver, with its primary route of excretion being through the bile. Due to its potent cytotoxic nature and narrow therapeutic index, its use necessitates careful monitoring for potential dose-limiting toxicities, particularly cardiotoxicity and myelosuppression, to ensure patient safety and optimize treatment outcomes.

Uses

• Treatment of various solid tumors.
• Management of hematological malignancies.
• Part of combination chemotherapy regimens.
• Used in certain sarcomas and carcinomas.

Directions For Use

Administered intravenously by a healthcare professional. Dosage and frequency are determined by the patient's condition and treatment protocol.

Benefits

• Effective against a broad spectrum of cancers.
• Induces apoptosis in cancer cells.
• Can be used in combination therapies.
• Available in different strengths for flexible dosing.
• A well-established chemotherapy agent.
• Contributes to improved patient outcomes in many cancers.

Side Effects

• Myelosuppression (low blood counts)
• Cardiotoxicity (heart damage)
• Nausea and vomiting
• Alopecia (hair loss)
• Mucositis (inflammation of mucous membranes)
• Fatigue and weakness
• Anorexia (loss of appetite)
• Diarrhea or constipation
• Red discoloration of urine
• Injection site reactions
• Hypersensitivity reactions
• Secondary malignancies (rare)

Safety Measures

• Alcohol - Avoid alcohol during doxorubicin treatment as it may exacerbate gastrointestinal side effects and potentially increase liver strain, which is already a concern with chemotherapy.
• Pregnancy - Doxorubicin is highly teratogenic and can cause severe fetal harm or death. It is contraindicated in pregnancy, and effective contraception must be used by both male and female patients during and for a period after treatment.
• Breastfeeding - Doxorubicin is excreted into breast milk and can cause serious adverse effects in a breastfed infant. Breastfeeding is contraindicated during doxorubicin therapy and for a specified period after the last dose.
• Liver - Doxorubicin is extensively metabolized in the liver. Dose adjustments are necessary in patients with impaired hepatic function to prevent increased systemic exposure and toxicity. Liver function tests should be monitored regularly.
• Kidney - While primarily excreted via bile, renal impairment can affect doxorubicin clearance to some extent. Caution is advised, and dose adjustments may be considered in severe renal dysfunction, though it's less critical than liver impairment.
• Lung - Doxorubicin is not typically associated with direct primary lung toxicity, but patients with pre-existing lung conditions should be monitored carefully, especially if they develop infections or other systemic complications during chemotherapy.
