Quinine is a quinoline derivative, which can combine with the DNA of Plasmodium to form a complex, inhibit the replication of DNA and the transcription of RNA, thereby inhibiting the protein synthesis of the parasite, and its effect is weaker than that of chloroquine. In addition, quinine can reduce the oxygen consumption of Plasmodium, inhibit the phosphorylase in Plasmodium and interfere with its sugar metabolism. Quinine also causes malaria pigment agglutination, but it develops slowly, rarely forms large clumps, and is often accompanied by cell death.

Electron microscope observation showed that the nucleus and outer membrane of the protozoa were swollen and had small vacuoles, and blood cell granules aggregated in the small vacuoles, which was different from the pigment agglutination of chloroquine. In blood, certain concentrations of quinine can cause premature rupture of parasitized red blood cells, thereby preventing schizont maturation. Quinine has no effect on the infrared stage and cannot cure benign malaria. Long-term treatment can cure malignant disease, but it has no direct effect on the gametophyte of falciparum malaria, so it cannot interrupt the transmission. Quinine has an inhibitory effect on the heart, prolongs the refractory period, slows conduction, and weakens its contractility. It has a weak excitatory effect on the pregnant uterus.

Applicable symptoms
Erectile dysfunction and pulmonary hypertension.
