RAPID DEPRESSURIZATION CONTROLLED ICE NUCLEATION IN PHARMACEUTICAL FREEZE-DRYING

A lyophilization method for lyophilizing products inside one or more vials within a lyophilization chamber is disclosed which includes humidifying a charge gas to a predetermined relative humidity, cooling shelves in the lyophilization chamber to a predetermined temperature, pressurizing the chamber with the humidified charge gas to a pressurization threshold to thereby achieving a target relative humidity level within the lyophilization chamber, and suddenly releasing pressure within the lyophilization chamber until a depressurization threshold is reached in a short time interval up to about 4 seconds, during the depressurization, product inside one or more vials nucleate.

Target residual moisture content for lyophilized drug product

Lyophilization methods for preparing protein formulations for long-term storage at room temperature or improved stability at refrigeration storage are provided. Specifically, the present application provides lyophilization methods to obtain a target percentage of residual moisture of a lyophilized product, such as 3-5% residual moisture. The secondary drying of the lyophilization can be conducted under controlling rate of desorption under a temperature which is similar to the shelf temperature of the primary drying. Alternatively, the lyophilization can be conducted without a distinguished secondary drying step.

Partial vacuum drying system and method

A material drying system provides for consistent and efficient drying of organic materials, such as cannabis. In certain embodiments, a partial vacuum drying system is used to dry the materials and includes a container, a heating system, a depressurization system, and a control system. Air in the container is heated to within a range of temperatures and a low vacuum is applied to assist with evaporation. In addition, the volume flow rate of air pulled out of the container is monitored and maintained at a predetermined rate, which pulls moisture away from the materials so as to prevent degradation of the materials during the drying process while also reducing drying time. A relatively high air volume flow rate is maintained at low pressure by adjusting the area of an opening in the chamber.
