AUTOMATED MACHINE AND PROCESS FOR MANUFACTURING VISCOUS PHARMACEUTICAL COMPOSITIONS FIELD OF THE INVENTION: The present invention relates to the mixing device for the process of manufacturing viscous pharmaceutical compositions and the specific design characteristics of mixing device provides a robust, reproducible manufacturing process to enhance the mixing of viscous pharmaceutical compositions with increased homogeneity and consistency. BACKGROUND OF THE INVENTION: Homogeneity of the final pharmaceutical composition is a critical aspect of mixing as uniformity impacts the final pharmaceutical composition in many ways such as stability and durability. Viscosity is one of the properties that influences mixing of composition to achieve homogeneity. Low viscosity materials have a lower resistance and rapid flow whereas high viscosity materials resist deformation and flow more slowly. Generally, for mixing of highly viscous materials, turbulent flow is desired within the mixing cylinders to create ideal mixing conditions but laminar flow shows dominance over turbulent flow because turbulent flow is directly dependent on the fluid viscosity, the higher the viscosity, the more challenging it is to achieve turbulent flow, wherein laminar flow refers to the type of fluid flow in which the fluid travels smoothly or in regular paths, in contrast turbulent flow, in which the fluid undergoes irregular fluctuations and mixing. For this reason, high viscosity materials are most difficult ingredients to mix effectively and present unique challenges during mixing. The PCT publication 1996007398 A2 related to sustained release parenteral composition consisting of gellable peptide salt and soluble carrier compounded into a dual syringe device including cylinder barrel, needle, plunger assembly. The WO’398 patent publication proved that R1 internal diameter of multi-connector element to the internal diameter of first chamber is equal to R2 internal diameter of multi-connector element to the internal diameter of second chamber the process lasts for too many hours for homogenization and the results obtained are not acceptable. The WO’398 patent publication does not contain perforated disk and the present invention provides good, homogenized product within lesser time and more transferring cycle made with equal ratio of R1 & R2. WO2022028739 A1 patent publication discloses manufacturing process for the preparation of viscous pharmaceutical formulations and formulations comprising combining a gellable material with a vehicle by using a two-chamber apparatus wherein one chamber contains the gellable material and the other chamber contains the vehicle and repeatedly moving the contents of one chamber to the other chamber and where the chambers have a specific ratio of internal diameters. The FENSOLVI (leuprolide acetate) label discloses a process for the manufacturing of a viscous pharmaceutical formulation in a two-chamber apparatus, manually transferring contents from one chamber to another chamber but in FENSOLVI (leuprolide acetate) label syringe A diameter less than syringe B and involving complete manual procedure. The PCT publication WO1996007398A2 related to injection device comprising two syringes, needle, plunger, connector but WO1996007398A2 patent publication does not contain perforated disk and there is no disclosure regarding time and cycle made to obtain good homogeneity product. EP2523653A2 discloses equipment consisting of two syringes (cylinders) connected via a three-way valve may be employed to mix the optionally acidified water for injection and the Lanreotide acetate. An efficient and capable mixing equipment is needed for mixing of highly viscous materials. There are paddles, anchor impellers, screw blades, kneading mixers have been used to enhance mixing and provide a homogenous final composition. Viscosity has the effect of resisting fluid motion, so the motion created by a mixer impeller in a viscous fluid may die out before it moves the entire contents of the tank. With all non-Newtonian fluids, the potential exists that a portion of a tank will remain unmixed because of inadequate fluid motion. Several problems are evident in mixing of viscous liquids such as (i) increased temperature due to the mechanical stirring; (ii) difficulties in collecting the final product without human intervention; (iii) requirement of more power consumption; (iv) difficulties that emerge from the nature of lyophilized powders, typically used in the manufacturing of semi-solid composition; and (v) problems related to sufficient homogeneity, which affect batch-to-batch consistency. Though, several equipment’s are available for mixing of viscous liquids, there is a need of specific design characteristics of automated machine that provides a robust, reproducible manufacturing process to enhance the mixing of viscous pharmaceutical compositions with increased homogeneity, consistency and to avoid the above stated problems. Hence, the present invention provides specific design characteristics of automated machine has one or more of the advantages of: (i) limited number of processing steps; (ii) no stagnant areas present inside the inter- connected dual cylinder system; (iii) power saving operation during mixing of viscous pharmaceutical compositions; (iv) facilitating the collection of the final viscous pharmaceutical composition without human interference; (v) shorter manufacturing times; and (vi) batch to batch consistency. Considering the above prior publications and available equipment’s, the inventors of the present inventors have understood, foresee and surprisingly found a better equipment for uniform mixing of viscous components done by the perforated disk, reduces the time for mixing cycles thereby increasing the productivity in less time without compromising on the homogeneity of the product.

Mixing process: After hydration completion mixing to be started from the biggest orifice from the perforated disk type valve (2). Mixing process comprising in four stages. 1. Mixing Stage 1: (Biggest orifice from the perforated disk type valve (2)) In this first stage the mixing is to be started from the biggest orifice in the perforated disk type valve (2). Now various speeds and number of strokes can be set from the human machine interface (HMI). 2. Mixing stage 2: In this stage the size of the orifice is to adjust to the next orifice from the perforated disk type valve (2). Again, various speeds and number of strokes can be set from the human machine interface (HMI). As the size of the orifice decreases the speed of the servo motor also needs to be decreased step by step. 3. Mixing Stage 3: In this stage the next position of the perforated disk type valve (2) is to be selected. Again, various speeds and number of strokes can be set from the human machine interface (HMI). As the orifices get smaller the vacuum port (7) can be used if pressure develops in the cylinders. This can be understood if the load on the motor is increased. 4. Mixing Stage 4: The next position of the perforated disk type valve (2) is to select in this stage. Again, various speeds and number of strokes can be set from the human machine interface (HMI). As the orifices get smaller the mixture becomes more and more like uniform gel and these small orifices helps to get rid of lumps and enhance in uniformity of mixtures. In mixing process, both first (1) and second cylinders (3) are comprising a means for applying pressure by pistons (4, 5) or vacuum using mechanical systems or pumps or pneumatic cylinders and transferring of the contents from one cylinder to another cylinder and vice versa is performed by means of a reciprocating movement. This reciprocating action results in mixing homogenously. When transferring is completed, the product can be collected from the second cylinder (3) as after the mixing ends the last stroke accumulates the gel in the second cylinder (3). In another embodiment, the proposed ratio diameters of cylinders allow the homogenization procedure to be completed at about less than 1.5 hours, during which about at least 150 transferring cycles are made, that is from the first to the second cylinder and vice versa.
