  • Publication number: 20200121751
    Abstract: The invention relates to medicines, and more particularly to an abortion medication and an administration thereof, where the abortion medication contains 40-60 mg/mL of a kidney bean lectin. The invention also provides another abortion medication, which contains 40-60 mg/mL of a kidney bean lectin, 40-50 mg/mL of an oligosaccharide and 6-9 mg/mL of NaCl. The two abortion medications provided herein are both capable of effectively terminating the pregnancy and are safe without toxic side effects. Moreover, these drugs can be reused several times. These abortion medications are administered intrauterinely, which enables the kidney bean lectin therein to show the best abortive effect, and the local administration of these drugs in the uterine cavity has relatively simple operation.
