Antimalarial Drug
Antimalarial medications or simply antimalarials are a type of antiparasitic chemical agent, often naturally derived, that can be used to treat or to prevent malaria, in the latter case, most often aiming at two susceptible target groups, young children and pregnant women. As of 2018, modern treatments, including for severe malaria, continued to depend on therapies deriving historically from quinine and artesunate, both parenteral (injectable) drugs, expanding from there into the many classes of available modern drugs. Incidence and distribution of the disease ("malaria burden") is expected to remain high, globally, for many years to come; moreover, known antimalarial drugs have repeatedly been observed to elicit resistance in the malaria parasite—including for combination therapies featuring artemisinin, a drug of last resort, where resistance has now been observed in Southeast Asia. As such, the needs for new antimalarial agents and new strategies of treatment (e.g., new combin ...

Chlorproguanil Hydrochloride-dapsone-artesunate
Chlorproguanil/dapsone/artesunate (abbreviated CDA) was an experimental antimalarial treatment that entered Phase III clinical trials in 2006. Development was halted because it was associated with an increased risk of haemolytic anaemia in patients with glucose-6-phosphate dehydrogenase deficiency. It consists of chlorproguanil, dapsone, and artesunate. (It can also be interpreted as Lapdap+artesunate.) Studies compared this combination against artemether/lumefantrine (Coartem) and against chlorproguanil/dapsone (Lapdap). This drug was developed in collaboration between GlaxoSmithKline, UNICEF, the World Bank, Medicines for Malaria Venture and the WHO Special Programme for Research and Training in Tropical Diseases Special or specials may refer to: Policing * Specials, Ulster Special Constabulary, the Northern Ireland police force * Specials, Special Constable, an auxiliary, volunteer, or temporary; police worker or police officer Literature * ''Specia ...

Biguanides
Biguanide () is the organic compound with the formula HN(C(NH)NH2)2. It is a colorless solid that dissolves in water to give highly basic solution. These solutions slowly hydrolyse to ammonia and urea. Synthesis Biguanide can be obtained from the reaction of dicyandiamide with ammonia, via a Pinner-type process. :\mathrm Biguanide was first synthesized by Bernhard Rathke in 1879. Biguanidine drugs A variety of derivatives of biguanide are used as pharmaceutical drugs. Antihyperglycemic agents The term "biguanidine" often refers specifically to a class of drugs that function as oral antihyperglycemic drugs used for diabetes mellitus or prediabetes treatment. Examples include: * Metformin - widely used in treatment of diabetes mellitus type 2 * Phenformin - withdrawn from the market in most countries due to toxic effects * Buformin - withdrawn from the market due to toxic effects File:Metformin.svg, Metformin, an asymmetric dimethylbiguanidine File:Buformin.svg, Buformin.

Proguanil
Proguanil, also known as chlorguanide and chloroguanide, is a medication used to treat and prevent malaria. It is often used together with chloroquine or atovaquone. When used with chloroquine the combination will treat mild chloroquine resistant malaria. It is taken by mouth. Side effects include diarrhea, constipation, skin rashes, hair loss, and itchiness. Because malaria tends to be more severe in pregnancy, the benefit typically outweighs the risk. If used during pregnancy it should be taken with folate. It is likely safe for use during breastfeeding. Proguanil is converted by the liver to its active metabolite, cycloguanil. Proguanil has been studied at least since 1945. It is on the World Health Organization's List of Essential Medicines. In the United States and Canada it is only available in combination as atovaquone/proguanil. Medical uses Proguanil is used for the prevention and treatment of malaria in both adults and children, particularly in areas where chloroqui ...
