    Action mechanism
    Praziquantel can kill adult schistosomiasis significantly. Its mechanism of killing insects, from the molecular level, is that praziquantel rapidly destroys the Ca2+ balance in the worm, on the one hand, it leads to the excitement of the worm body activity and muscle contracture, so that the parasitic schistosoma parasitic on the portal vein system can not be adsorbed on the blood vessel wall and is carried by the blood flow into the liver (liver migration), and then is damaged; Second, the syncytial cortex of schistosoma is damaged. In addition to affecting the absorption, excretion and secretion functions of the worm, resulting in the disturbance of glucose metabolism and enzyme system, the body surface antigen determining cluster of the worm is exposed, which can be recognized by the host immune system and attract a large number of inflammatory cells such as neutrophils, eosinophils and macrophages to gather around the worm and attack.
    Side effect
    The common side effects of praziquantel are as follows: 1. Dizziness, headache, nausea, abdominal pain, diarrhea, weakness, and limb soreness may occur 1 hour after the first use of praziquantel. Generally, the degree is mild, the duration is short, and the treatment is not affected. 2. Palpitations, chest tightness and other symptoms were observed in a few cases. Electrocardiogram showed T-wave changes and extrasystole, and occasionally supraventricular tachycardia and atrial fibrillation. 3, a few cases may appear transient aminotransferase elevation, toxic hepatitis, etc. 4, occasionally can induce mental disorders or gastrointestinal bleeding. 5, brain hernia, allergic reactions (rash, asthma) and so on have also been seen.
