Pharmacological Properties

The synergistic combination of Sulfadoxine and pyrimethamine. These ingredients act by blocking two enzymes involved in biosynthesis of folinic acid in parasites. Malagon (Sulfadoxine & Pyrimethamine) is also sensitive and most effective to resistant organisms, to conventional antimalarials like Chloroquine and its derivatives. The incidence of resistance with Malagon is rare and negligible.

Malagon is absorbed orally and excreted mainly by kidney. Following a single dose administration of Malagon (Sulfadoxine & Pyrimethamine). Sulfadoxine peak plasma concentration 51 to 76 mcg/ ml were achieved in 2.5 to 6 hours and Pyrimethamine peak plasma concentration 0.13 to 0.4 mcg/ml were achieved in 1.5 to 8 hours. The approximate elimination half life of Sulfadoxine ranges from 100 to 231 hours with a mean of 169 hours where as pyrimethamine half life ranges from 54 to 148 hours with a mean of 111 hours.
