Some great benefits of lyophilization consist of: Simplicity of processing a liquid, which simplifies aseptic dealing with Improved security of the dry powder Removing of h2o without extreme heating on the product or service Increased product stability inside a dry state Speedy and simple dissolution of reconstituted merchandise Shortcomings of lyophilization contain: Elevated managing and processing time Will need for sterile diluent upon reconstitution Value and complexity of apparatus The lyophilization process normally includes the subsequent steps: Dissolving the drug and excipients in a suitable solvent, usually drinking water for injection (WFI).
