This product is a nucleoside diphosphate reductase inhibitor, which can prevent the reduction of nucleotides to deoxynucleotides, interfere with purine and pyrimidine base biosynthesis, selectively hinder DNA synthesis, and have no blocking effect on RNA and protein synthesis. Cycle-specific drugs, S-phase cells are sensitive.
| drug action and clinical application | hydroxyurea is an anticancer drug for the treatment of chronic myeloid leukemia. as early as the 20s, it was observed that hydroxyurea caused rabbits to produce giant erythrocyte hemogram similar to pernicious anemia and inhibited leukocyte production. Its inhibitory effect on L1210 mouse leukemia was discovered in 1963. Hydroxyurea can induce bacteria to produce a molecule that is toxic to itself to achieve the purpose of killing bacteria. Hydroxyurea, also known as hydroxyurea, hydroxyurea, carbamoyl hydroxyurea, is a nucleoside diphosphate reductase inhibitor, which can prevent the reduction of nucleotides to deoxynucleotides, interfere with purine and pyrimidine base biosynthesis, selectively hinder DNA synthesis, and partially inhibit the conversion of ribonucleic acid into deoxyribonucleotides. It has no blocking effect on RNA and protein synthesis. Hydroxyurea is a cycle-specific drug, which is sensitive to S-phase cells and can induce hematological remission of chronic myeloid leukemia. Compared with alkylating agents Baifan and Mafan, the incidence of secondary leukemia is low. The myelosuppressive effect of hydroxyurea lasts several days to several weeks and is easier to control than alkylating agents. Clinically, hydroxyurea is suitable for the treatment of chronic myeloid leukemia, acute lymphocytic and acute non-lymphocytic leukemia with high cell count, spontaneous thrombocytosis, polycythemia vera, and retinoic acid syndrome to prevent acute myeloid leukemia, treatment of sickle cell anemia with frequent pain attacks. In addition, hydroxyurea is also effective in the treatment of head and neck tumors, recurrent metastatic ovarian cancer, and kidney cancer. |
| usage and dosage | common dosage for adults: ① chronic myeloid leukemia, the general starting dose is 20-30 mg/kg per day according to body weight, once or twice orally. when the white blood cell drops below 10 × 109/L, the dosage is reduced to about 20 mg/kg per day, and the oral administration is maintained or changed to intermittent administration. ② head and neck cancer and ovarian cancer, the dose is 60~80 mg/kg per time according to body weight or 2000~3000mg/m2 according to body surface area, taken orally once every 3 days, taken alone or combined with radiotherapy. |
