Lyophilized Injection is form of Injection obtained from lyophilization process or deep freeze drying process. In this process moisture is removed from the drug product with the help of vacuum pressure when it is in frozen form. In this procedure solid state directly converted into vapour state skipping the liquid state also known as sublimation process.
