The present invention provides a prefilled protamine sulphate syringe for preserving efficiency and aseptic drug delivery. The present syringe is prefilled and so the syringe itself contains protamine sulphate which does not require the said drug to be filled from vial. Therefore, the said drug is not exposed to air and hence is prevented from oxidation which would otherwise affect the efficiency of the drug. The present syringe also avoids the contamination of protamine sulphate adding to preservation of the drug"s efficiency. Hence the drug can be aseptically delivered.
