Bendamustine HCl
Product Description:
Bendamostine hydrochloride was first developed by ozegowski and his colleagues in the microbial experimental Association in Jena, Germany in the early 1860s. The initial purpose was to connect an alkylated nitrogen mustard (a non effective alkylating agent) with a purine and an amino acid. Compared with nitrogen mustard phenylbutyrate, the main advantage of the newly synthesized compound is its water solubility. It was widely used, but until the end of the cold war, the drug has been in Europe for a number of single drugs or other drugs in the treatment of a variety of hematological malignancies or non Hodgkin's lymphoma, multiple myeloma, CLL and breast cancer and other solid tumors clinical research, the curative effect is very observable, significantly reduce the recurrence rate and mortality rate, and small adverse reactions, good safety. So far, bendamostine hydrochloride single drug or combined treatment has been designated as the first-line or second-line treatment option for a variety of hematological malignancies by European and American clinical guidelines.
Pharmacological action:
The exact mechanism of bendamostine hydrochloride is not very clear, but it is known that the drug is a nitrogen mustard derivative carrying a purine like benzimidazole ring, which has the dual action mechanism of alkylating agent and purine analogue (antimetabolic drug). Bendamostine hydrochloride can cause cell death through several different ways, and is effective for cells in quiescence and division.
Indication:
In March 2008, the US Food and Drug Administration (FDA) first approved bendamostine hydrochloride for the treatment of chronic lymphocytic leukemia (CLL). In October of the same year, FDA approved the second indication of the drug, that is, during the treatment of rituximab (rituximab) or rituximab containing regimen, or within 6 months of treatment, Patients with inert B-cell non-Hodgkin lymphoma (NHL) whose condition is still progressing.
Contraindication:
It is forbidden for those allergic to bendamostine hydrochloride and mannitol.
Adverse reactions and side effects:
Common adverse reactions include nausea, vomiting, diarrhea, fatigue, weakness, rash, itching Some symptoms and signs of infection (such as persistent throat pain, fever and chills), easy to bruise / bleed and oral ulcer; serious adverse reactions may include bone marrow suppression, tumor lysis syndrome, etc. it may cause mild or serious allergic reactions. The patient may have allergic symptoms such as skin rash, facial swelling and dyspnea during or early after administration. It may affect the fetus Therefore, women should take appropriate contraceptive measures and stop breastfeeding during and within 3 months after treatment.
