71939-50-9 - Reference Information

Use dihydroartemisinin can be used in a variety of malaria, especially for anti-chloroquine, treatment of falciparum malaria and dangerous cerebral malaria.
medicinal properties and application dihydroartemisinin has a strong killing effect on asexual bodies of Plasmodium falciparum, it can quickly control the symptoms and kill the various forms of the malaria parasite in the vegetative period, and it is also effective for chloroquine and piperaquine resistant falciparum malaria, and the toxicity is low. Animal experiments have found that administration in the induction phase of pregnancy in mice can increase the occurrence of fetal absorption, but no teratogenic effect. Oral absorption, oral administration of this product 2 mg/kg,tmax 1.33h,Cmax 0.71 μg/ml. Clinical for various types of malaria, especially for chloroquine, piperaquine-Resistant Brain, dangerous disease of falciparum malaria rescue.
adverse reactions There was a transient decrease in peripheral reticulocytes and white blood cells, and elevated transaminase. Dihydroartemisinin piperaquine has Nausea, Vomit, Abdominal Pain, Diarrhea and loss of appetite, etc., as well as dizziness, Head Pain, rash, skin itching and so on.
principle of action dihydroartemisinin is a derivative of artemisinin. Has a strong killing effect on the parasite asexual body, can quickly control the symptoms, and kill the protozoa, against chloroquine, Piva falciparum equally effective.
contraindication is contraindicated for those allergic to this product. Severe liver and kidney disease, blood diseases, the first 3 months of pregnancy disabled Dihydroartemisinin and Piperaquine Phosphate Tablets.
precautions should be used with caution during pregnancy; Dihydroartemisinin and Piperaquine Phosphate Tablets has a long half-life, and should not be used repeatedly within half a month.

 

  1. appropriate amounts of the product and the reference product of dihydroartemisinin were dissolved and diluted with toluene to prepare a solution containing about 0.1 mg per 1 ml, which was used as the test solution and the reference solution. According to the thin layer chromatography (General 0502) test, accurately absorb the above two solutions each 10 u1, point on the same silica gel G thin layer plate, with petroleum ether (boiling range is 40~60°C)-Ether (1:1) as a developing solvent, expand, dry, sprayed with 2% vanillin in sulfuric acid ethanol solution (20-100), heated at 85 ° C. For 10-20 minutes to clear spots. The position and color of the main spot displayed by the test solution should be consistent with the main spot of the control solution.
  2. in the chromatogram recorded under the content determination item, the retention time of the main peak of the test solution should be consistent with the retention time of the main peak of the reference solution.
  3. The infrared absorption spectrum of this product should be consistent with that of the control (Spectrum set 696).
  4. two items (1) and (2) above can be selected as one item.
