Avastin instructions for use

Avastin belongs to the class of monoclonal antibodies, which are used for the treatment of tumor diseases.

Active ingredient: Bevacizumab.

pharmachologic effect

Avastin is a recombinant humanized antibody that not only binds, but also neutralizes the biochemical effects of endothelial growth factor, which leads to disruption of the blood supply to the tumor and the death of its cells. In addition, the use of Avastin inhibits the progression of metastatic lesions emanating from organs such as the pancreas, colon, prostate, and mammary gland.


The drug has a very low clearance (ie, slowly excreted from the body) and a long half-life. This makes it possible to maintain the optimal therapeutic concentration of the drug in the blood for 2-3 weeks after a single infusion over a long time interval.

The use of Avastin in elderly patients without concomitant diseases can be carried out according to the standard scheme without dose adjustment.

The possibility of using Avastin in patients with hepatic and renal insufficiency has not been studied.

With a low serum albumin concentration, the activity of the drug and its half-life may increase significantly.

Indications for use

  • Metastatic cancer with a lesion of the colon (colorectal), with the combined treatment with various derivatives of fluoropyrimidine.
  • Inoperable metastatic lesions of the lungs. In this case, the drug is used in conjunction with platinum preparations.
  • Metastatic or advanced kidney cancer. In this case, alpha-2a interferons are added to first-line therapy.
  • Cancer of the fallopian tube, ovarian or primary peritoneal tumors. Combined pharmacotherapy with paclitaxel or carboplatin is advisable.
  • The ineffectiveness of the treatment of breast cancer with other drugs.
  • Therapy of tumor diseases in ophthalmology.

Dosage and recommended dose

The drug is used only in the hospital under the supervision of a chemotherapist. If possible, the therapy of malignant tumors should be carried out before the progression and the moment of generalization of the process.

The starting dose of Avastin is administered intravenously slowly over 90 minutes, and the patient’s condition is monitored. In the event that the patient underwent the infusion satisfactorily, the subsequent drip infusions are carried out somewhat faster - in 60 minutes. If the patient tolerates this rate of drug administration satisfactorily, then at a subsequent infusion time can be limited to 30 minutes.

Important! Avastin should not be injected into the vein in a vein, as this will cause a high incidence of serious adverse reactions. It is also impossible to dilute the concentrate with glucose solution.

With tumor lesions of the large intestine, the dose of the drug is 5 mg / kg body weight, while Avastin is administered 1 time in 14 days.

In case of neoplastic lung diseases, the dose of Avastin is selected on the basis of 7.5 mg / kg body weight. At the beginning of the course of tumor treatment, the described drug is used only in combination with platinum drugs, after a while they switch to monotherapy with Avastin. The frequency of administration of monoclonal antibodies is 1 time in 3 weeks.

With kidney lesions, the dose is calculated as follows: 10 mg / kg of body weight, while infusion is carried out 1 time in 2 weeks.

When tumors of the female genital or peritoneum Avastin at the beginning of treatment is combined with chemotherapy for 6 cycles. Then monoclonal antibody therapy is carried out for 15 months, the dose is 15 mg / kg body weight. The multiplicity of the introduction - 1 time in 21 days.

With metastatic breast cancers, Avastin dose is 10-15 mg / kg body weight. In this case, the drug is administered 1 time in 3 weeks.

Application in pediatric practice: at present, data on the safety profile of Avastin in children is not available.

Terms of preparation of the solution for infusion: due to the fact that antimicrobial reagents are not added to the vial with antibodies, the solution must be prepared immediately before use with strict observance of aseptic rules.

The concentrate is diluted only (!) With a physiological solution of sodium chloride to the 100 ml mark on the vial. In the event that a larger volume of infusion is required, dilution to the 200 ml mark is acceptable.

If the drug remains in the vial after intravenous infusion, it is strictly prohibited to use it for subsequent administration.

TJ Moore: Thank you for posting this information!  Very helpful in understanding how our insurance works should we receive that diagnosis that would turn our lives upside down.

Mary Helen Manoyan Garabedian: Thank you for this information. I am a lung cancer /EGFR mutation/ patient. Looking for lung cancer fundraising society. Who are they and how can I help?

drewzillasaurusrex: Cancer is a blight of the modern industrial age. Industry generates the pollution that causes the disease. The medical industry and big pharma reap the rewards of your suffering.

Toni: What's laughable is meat has been eaten for millions of years and wheat and sugar has been killing us for a couple of hundred when the slaves were dragged over to grow the sugar and process it along the the wheat and maize etc. That's when it all started killing us.

Janine M: When will the medical establishment catch up? You expect some ignorance, unfortunately, from purely allopathic practitioners. But even "functional MDs" and "holistic MDs" have balked at my being vegan. They wish I would at least eat eggs and fish. My newest doctor (family practitioner) thinks I should follow a keto diet. It's all very frustrating, because doctors are still seen as authority figures, so people follow their bad advice. What happened to "first, do no harm?" I see harm all over the place, even in 2020. This video was from 8 years ago. Thanks to doctors like this for calling out the truth, but I can't wait for the day when this is finally the accepted wisdom.
