  • Publication number: 20230277417
    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.

  • Publication number: 20220339159
    Abstract: A process for preparing a powder for reconstitution as a suspension includes the following steps: First, complexing Valaciclovir with an ion exchange resin and forming Drug-Resin complex (DRC) particles. The complexing includes Dry blending of Drug:Ion Exchange Resin in a ratio 1:0.8 to form a blend; Kneading the blend with water in a ratio of Drug:Ion Exchange Resin:Water 1:0.8:0.5 to form a wet mass; Drying of the wet mass at 40° C. Next, milling of the Drug-Resin complex particles until particle size gets less than 250 ?m, and then dry mixing of the Drug-Resin complex particles with excipients to form an internal phase. The excipients of the internal phase comprise a suspending agent and a pH agent, and the suspending agent forms a film around each DRC particle and the film decreases interparticle attraction. Next, mixing the internal phase with excipients of an external phase to form the powder, and then sifting the powder to eliminate any clumps.
