Pharmacological properties

Pharmacodynamics.

Mechanism of action

Bevacizumab is a recombinant humanized monoclonal antibody produced by DNA technology in Chinese hamster ovary cells. Bevacizumab binds to vascular endothelial growth factor (VEGF), a key factor in vasculogenesis and angiogenesis, thereby inhibiting the binding of VEGF to its receptors Flt-1 (VEGFR-1) and KDR (VEGFR-2) on the surface of endothelial cells . Neutralization of the biological activity of vascular endothelial growth factor leads to a decrease in the vascularization of tumors, normalizes vessels not affected by the tumor, inhibits the formation of new vessels in the tumor, thus inhibiting tumor growth.

Administration of bevacizumab or its parent murine antibody in a xenograft model of malignant tumors in athymic mice produced active antitumor activity against human tumors, including colon, breast, brain, pancreatic, and prostate tumors. The progression of the metastatic disease was inhibited, and the permeability of the microvascular bed was also reduced.

Avastin in the form of infusions cannot be administered or diluted with glucose solutions. The drug cannot be mixed with other drugs, with the exception of 0.9% sodium chloride solution for injection.

The required amount of bevacizumab should be withdrawn and diluted to the required volume for administration with 9 mg/ml (0.9%) sodium chloride solution for injection. The concentration of bevacizumab in the prepared solution should be in the range of 1.4–16.5 mg/ml. In most cases, the required amount of the drug Avastin can be diluted with 0.9% sodium chloride solution for injections to a total volume of 100 ml.

Before use, the solution must be inspected for the presence of mechanical inclusions and discoloration.

Avastin intended for single use only, as the medicine does not contain a preservative. Any unused product or waste material should be disposed of in accordance with local requirements.

No incompatibility of the drug Avastin was observed® with bags made of polyvinyl chloride or polyolefin, as well as with systems for infusion.

The chemical and physical stability of the prepared solution is maintained for 48 hours at a temperature of 2 to 30 °C in 9 mg/ml (0.9%) sodium chloride solution for injection. From a microbiological point of view, the drug should be used immediately. If the drug is not used immediately, the user is responsible for the storage time and conditions of the prepared solution. The finished solution can be stored for no more than 24 hours at a temperature of 2 to 8 °C, if the dilution is carried out in controlled and validated aseptic conditions.
