  • Process and apparatus for preparing viscous pharmaceutical formulations
    Patent number: 12778848
    Abstract: A process may allow the preparation of one or more viscous pharmaceutical formulations and an apparatus may be configured for implementing such a process. A gellable material may be introduced into one chamber, a vehicle may be introduced in the other and by alternately applying force to each chamber, mixing and homogenization may take place. The internal diameter of the connection equipment of the two chambers may be equal to the outlet internal diameters of the chambers. Each chamber may have different diameter, with the first chamber being larger than the second chamber, so as to allow the process to be executed in a simple and more convenient manner.
