Description
Curator's Comment: Description was created based on several sources, including http://www.ema.europa.eu/docs/en_GB/document_library/Maximum_Residue_Limits_-_Report/2009/11/WC500012185.pdf https://www.ncbi.nlm.nih.gov/pubmed/9776305

Cinchonidine is an alkaloid found in Cinchona officinalis and Gongronema latifolium. Cinchonidine is an antimalarial drug which has been used clinically in malaria caused by Plasmodium falciparum. Cinchonidine is reported as an ingredient of Quinimax in a number of countries. Quinimax is a combination of four alkaloids (quinine, quinidine, cinchoine and cinchonidine).

Sample Use Guides

Fifty-five children were given 20 mg/kg of the diluted injectable form of Quinimax (a quinine, quinidine, cinchonine, cinchonidine association) intrarectally. A further 11 children with malaria were treated with 12.5 mg/kg of the same Quinimax solution by the intramuscular route. All the children were treated twice a day for 3 d.
