Chloroquine atovaquone Hydroxychloroquine induced cardiomyopathy in systemic lupus erythematosus Do you have to wean off hydroxychloroquine What is plaquenil Prescribed for Malaria Prevention, Malaria. Malarone may also be used for purposes not listed in this medication guide. Prescribed for Lyme Disease - Arthritis, Dermatomyositis, Malaria Prevention, Malaria, Rheumatoid Arthritis, Systemic Lupus Erythematosus. May also be prescribed off label for Sjogren's Syndrome. The UK Patents Court has found that GSK's patent for the anti-malarial drug Malarone EPUK No. 0670719 is invalid. Malaria is one of the most prevalent tropical diseases, and Malarone is the most successful anti-malarial prophylactic in the UK. Malarone contains a combination of the compounds atovaquone and proguanil in the ratio 52. There is no evidence that proguanil is harmful in prophylactic doses during pregnancy. Because of the vulnerability of pregnant women to falciparum malaria, it should be used at full prophylactic dosage wherever the disease is prevalent and likely to be responsive to proguanil, if chloroquine is not available or is unlikely to be effective. The antimalarial activity of Proguanil eventually was ascribed to cycloguanil, a cyclic triazine metabolite and selective inhibitor of the bifunctional plasmodial dihydrofolate reductase-thymidylate synthetase. Formula-I Background and Prior art: Proguanil (PALUDRINE) is the common name for chloroguanide, a biguanide derivative that emerged in 1945 as a product of British antimalarial drug research.
