Pharmacodynamics of the drug Falcidin
Dihydroartemisinin: Dihydroartemisinin mainly works to interfere with the membrane structure of autotrophs (asexual bodies in red blood cells) such as: twisting the digestive vacuole membrane, causing mitochondria and The nuclear membrane expands, separating the ribosome from the endoplasmic reticulum, leading to cytoplasmic vacuoles and autophagy. In addition, the drug has a biochemical effect on the synthesis of proteins and nucleic acids. Piperaquine phosphate: Piperaquine phosphate inhibits the physiological function of the digestive vacuole membranes of autotrophs, inducing autophagy of the parasite. Pharmacokinetics of falcidin Dihydroartemisinin: After oral administration, Dihydroartemisinin is rapidly absorbed, peak plasma concentrations are reached within 1 hour, and elimination half-life is about 4 hours. Widely distributed to liver, bile and kidney. Approximately 80% is excreted in the urine and faeces within 24 hours of oral administration. Dihydroartemisinn is metabolized to two inactive forms, deoxydihydroartemisinin and dihydroxydihydroartemisinin.
Piperaquine Phosphate: Piperaquine has high lipid solubility with large volume of distribution, stable bioavailability, relatively long elimination half-life, clearance coefficient. ) was significantly higher in children than in adults.
After oral administration, approximately 80-90% of Piperaquine phosphate is absorbed in 24 hours. The drug is widely distributed in the body, mainly in the liver, kidneys, lungs and spleen.
