FIELD: medicine, pharmaceutics.
SUBSTANCE: invention refers to a method for preparing an agent for making 99m Tc Norfloxacin. The above method involves preparing tin (II) chloride dihydrate to be mixed with a norfloxacin hydrochloride powder, freezing the prepared mixture at liquid nitrogen temperature, lyophilising at temperature -50°C in vacuum -0.0015 torr for at least 20.5 hours and drying additionally for at least 5.5 hours at temperature +16±2°C.
EFFECT: invention prolongs the shelf-life of the agent for preparing 99m Tc Norfloxacin by increasing its stability.
