Clinical use of praziquantel in China.
Praziquantel, a broad-spectrum anthelmintic developed by E. Merck and Bayer AG in Germany in the early 1970s, was synthesized in the People's Republic of China in 1977 and given the Chinese name Pyquiton. After a series of pharmacological and toxicological studies in China, praziquantel was released for clinical use in 1978. The drug is now available for treatment of human schistosome and other trematode infections as well as the treatment of cestode infections including cysticercosis. However, much of the clinical work has been published in Chinese journals that may not be universally familiar. This article summarizes some of the key aspects of these reports, dealing with the clinical use of praziquantel against schistosomiasis japonica and other helminth infections in China.
