5.0. BATCH MANUFACTURING PROCESS :
5.1 Ensure That compounding Vessel is cleaned before starting the procedure.
5.2 Collect 220 Liters Water for Injection in a Mixing vessel send BET sample and cool up to 40- 45°C with Continuous nitrogen Purging.
5.3 From the step 1st take approx. 50 litres Water for Injection a side in other SS vessel for final volume make up.
5.4 Add and dissolve Di Sodium EDTA with continuous stirring and check the clarity of solution.
5.5 Add and dissolve sodium Acetate IP with continuous stirring and check the clarity of solution.
5.6 Add and dissolve Methylcobalamin IP with continuous stirring and check the clarity of solution.
5.7 Add and dissolve Benzyl Alcohol with continuous stirring and check the clarity of solution.
5.8 check the initial ph (pH RANGE 3.3 TO 5.5).
5.9 Adjust pH of bulk solution with 10% Glacial Acetic Acid. and finally make up the volume with W.F.I and then check the final ph.
5.11 Intimate the IPQA to collect Bulk solution and send to QC for analysis.
5.2 FILTRATION :
5.2.1 Ensure that Bulk solution Release from QC Department.
5.2.2 Filter the Bulk solution from Mixing Vessel to Collection Vessel through 0.2 micron sterilized filter.
5.2.3 Check the Pre and Post Filter Integrity.
