The present invention is a prefilled syringe containing Arteether which is cost effective and enables contamination free administration of Arteether. The drug Arteether can support bacterial growth if it gets contaminated. The Arteether is usually administered malaria related medications when infectious contaminants can lead to other health complications. The present syringe is prefilled and does not require filing the drug from vial and so there are no chances of Arteether getting contaminated. Hence the present syringe enables contamination free administration of Arteether. The vials are not required and hence the syringes are cost effective in terms of manufacture, handling, transport as well as disposal. In addition, medical wastage is also reduced as the vials are not at all required and further are not disposed after use only the used up syringes are disposed as medical waste.
