NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of essential Active Pharmaceutical Ingredients (APIs), including Sulfadoxine, a critical component in combination therapies, most notably with Pyrimethamine for treating malaria. This combination leverages synergistic mechanisms to effectively combat the malaria parasite, Plasmodium falciparum.
Sulfadoxine functions as a sulfonamide that inhibits the enzyme dihydropteroate synthase (DHPS), which is involved in the synthesis of folic acid required by the parasite. Pyrimethamine, on the other hand, targets dihydrofolate reductase (DHFR), another enzyme in the same folate synthesis pathway. By inhibiting two distinct steps in this vital metabolic pathway, the combination therapy significantly reduces the development of resistance and enhances therapeutic efficacy.
The importance of high-purity Sulfadoxine powder cannot be overstated when formulating such combination drugs. NINGBO INNO PHARMCHEM CO.,LTD. provides pharmaceutical grade Sulfadoxine with a purity exceeding 99%, ensuring that the resulting medications are both safe and effective. Pharmaceutical companies that buy Sulfadoxine powder online from us can be confident in the quality and consistency of their raw materials.
The widespread use of Sulfadoxine/Pyrimethamine (often known by brand names like Fansidar) has been a cornerstone of malaria control strategies in many endemic regions. Although resistance patterns can emerge, the combination remains a valuable tool, particularly in specific contexts and for intermittent preventive treatment in pregnant women (IPTp), where recommended.
As a dedicated Sulfadoxine manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting global health efforts by ensuring a reliable supply of this vital API. We understand the critical role that high purity Sulfadoxine plays in combating malaria and other infections, and we are proud to be a trusted partner for pharmaceutical manufacturers worldwide.
