Rubizen
Rubizen Uses, Dosage, Side Effects, Food Interaction and all others data.
Rubizen, an anthracycline with cytotoxic properties. It inhibits DNA and RNA synthesis by steric obstruction after intercalating between DNA base pairs that triggers DNA cleavage by by topoisomerase II. It also inhibits DNA helicase and generates cytotoxic free radicals.
Rubizen is an antineoplastic in the anthracycline class. General properties of drugs in this class include: interaction with DNA in a variety of different ways including intercalation (squeezing between the base pairs), DNA strand breakage and inhibition with the enzyme topoisomerase II. Most of these compounds have been isolated from natural sources and antibiotics. However, they lack the specificity of the antimicrobial antibiotics and thus produce significant toxicity. The anthracyclines are among the most important antitumor drugs available. Doxorubicin is widely used for the treatment of several solid tumors while daunorubicin and idarubicin are used exclusively for the treatment of leukemia. Rubizen may also inhibit polymerase activity, affect regulation of gene expression, and produce free radical damage to DNA. Rubizen possesses an antitumor effect against a wide spectrum of tumors, either grafted or spontaneous. The anthracyclines are cell cycle-nonspecific.

Uses
Rubizen Injection is an anthracycline topoisomerase II inhibitor used as a component of adjuvant therapy in patients with evidence of axillary node tumor involvement following resection of primary breast cancer
Rubizen is also used to associated treatment for these conditions: Breast Cancer, Breast Cancer Stage II, Breast Cancer Stage III, Colorectal Cancers, Hormone Refractory Prostate Cancer, Non-Small Cell Lung Carcinoma (NSCLC), Ovarian Cancer, Papillary transitional cell carcinoma of bladder, Recurrent Superficial Bladder Cancer, Small Cell Lung Cancer (SCLC), Soft Tissue Sarcoma (STS), Stomach Tumor, Carcinoma in situ of urinary bladder
How Rubizen works
Rubizen has antimitotic and cytotoxic activity. It inhibits nucleic acid (DNA and RNA) and protein synthesis through a number of proposed mechanisms of action: Rubizen forms complexes with DNA by intercalation between base pairs, and it inhibits topoisomerase II activity by stabilizing the DNA-topoisomerase II complex, preventing the religation portion of the ligation-religation reaction that topoisomerase II catalyzes. It also interferes with DNA replication and transcription by inhibiting DNA helicase activity.
Dosage
Rubizen dosage
Acute leukaemias; Lymphoma; Multiple myeloma; Solid tumours:
- As a single agent: 60-90 mg/m2 3-4 wkly.
- Max (total cumulative dose): 0.9-1 g/m2.
- Palliative care: 12.5-25 mg/m2 once wkly.
Adjuvant treatment in axillary-node positive breast cancer: Recommended starting doses: 100-120 mg/m2 as a single dose on day 1 or as 2 divided doses on days 1 and 8 of each 28-day cycle. Repeat for 6 cycles.
Intravesical Local treatment of bladder carcinoma: As 0.1% soln: 50 mg/wk for 8 wk; reduce dose if chemical cystitis develops.
For carcinoma in-situ: 80 mg in 50 mL wkly.
For prevention of recurrence in patients who have undergone transurethral resection: 50 mg/wk for 4 wk, followed by 50 mg/mth for 11 mth; retain soln in the bladder for 1 hr during each administration.
Side Effects
In early breast cancer, acute adverse events occurring in ≥10% of patients are leucopenia, neutropenia, anemia, thrombocytopenia, amenhorrhea, lethargy, nausea/vomiting, mucositis, diarrhea, infection, conjunctivitis/keratitis, alopecia, local toxicity and rash/itch.
Long term adverse events occurring at a frequency of 1-2% are asymptomatic drops in LVEF and CHF and secondary leukemia.
Toxicity
bone marrow aplasia, grade 4 mucositis, and gastrointestinal bleeding
Precaution
Previous extensive radiotherapy, bone infiltration by tumour, severe renal and hepatic dysfunction. May cause tumor lysis syndrome or radiation recall. Elderly women >70 yr. CV disease, hypertensive cardiomyopathy; monitor hematological and cardiac function regularly. Extravasation during IV admin may result in severe local tissue necrosis. Do not give via IM/SC routes as extravasation can lead to severe local necrosis
Interaction
Paclitaxel and other anthracyclines. Cimetidine, heparin. Antineoplastic drugs, cardiotoxic drugs, radiation, hepatoactive drugs.
Food Interaction
- Drink plenty of fluids. Increased fluid intake increases urine output and the excretion of uric acid.
Rubizen Alcohol interaction
[Moderate]
The concomitant or sequential use of epirubicin with agents known to induce hepatotoxicity may potentiate the risk of liver injury.
Rubizen undergoes elimination through the hepatobiliary system.
Caution and clinical and laboratory monitoring for signs of liver injury are advisable before, during, or after use of epirubicin with other agents that are potentially hepatotoxic.

Rubizen comes as a solution (liquid) to be injected intravenously (into a vein) by a doctor or nurse in a medical facility along with other chemotherapy medications.
How long does Rubizen take to work?
It can take up to 30 minutes if you have it on its own but it might take longer if you have it with other drugs. For bladder cancer, you might have Rubizen every week, for up to 8 weeks.
How long does Rubizen stay in my system?
This medicine may turn your urine red for 1 or 2 days after your treatment.
How long can I take Rubizen?
Chemotherapy is often given for a specific time, such as 6 months or a year.
Who should not take Rubizen?
You should not use Rubizen if you have an untreated or uncontrolled infection, severe liver disease, severe heart problems, or if you have recently had a heart attack. You may not be able to use Rubizen if you have already been treated with a certain amount of other cancer medications. You should not use this medication if you are allergic to Rubizen or similar medications.
