MANUFACTURING PROCESS: 

1. Fit the mesh # 40 Stainless Steel Sieve on the Sifter as per its SOP and place Stainless Steel Container below the discharge hopper.
2. Sift the 0.065 kgs of Aerosil through 40 mesh Stainless Steel Sieve on the sifter and let it to collect in the container kept below the discharge hopper.
3. Sift the 4.750 kgs of Di-Calcium Phosphate through 40 mesh Stainless Steel Sieve on the sifter and collect in the same container.
4. Sift the 0.200 kgs of Loperamide HCl through 40 mesh Stainless Steel Sieve on the sifter and collect in the same container.
5. Sift the 1.335 kgs of Magnesium Stearate through 40 mesh Stainless Steel Sieve on the sifter and collect in the same container.
6. Sift the 1.650 kgs of Talcum through 40 mesh Stainless Steel Sieve on the sifter and collect in the same container.
7. Sift the 20.0 kgs of Norfloxacin through 40 mesh Stainless Steel Sieve on the sifter and collect in the separate container.
8. Transfer all the sifted ingredients to Roto Cube Blender and blend together for 1 hour by operating it as
   per its SOP .
9. Weigh the whole batch. The weight of whole batch should be in range between 27.720 kg – 28.0 kg.
10. Send the sample to Quality Control Department for bulk testing.
11. Start filling of Empty Hard Gelatin capsules, 280 miligrams of blended powder in each capsule shell by using Automatic Capsule Loading Machine and Semiautomatic Capsule Filling Machine as per their SOP 
12. Polish the filled capsules by using Feeder, Sorter & Capsule Polishing Machine With A.D.U. as per its
    SOP 
13. Strip pack the filled capsules by using Strip Packing Machine as per its SOP 

IN-PROCESS CONTROLS: 

The following in-process controls should be maintained during the processing:

1. Check Raw materials used for manufacturing purpose are all approved materials and have ‘Released’ labels fixed on it.
2. All weighed Raw materials should be counter-checked by Assistant Manufacturing Chemist. If any discrepancy is noticed, it should be immediately brought to the notice of Production Pharmacist and QC/QA Manager.
3. Physical characteristics of Raw material like colour, odour, and consistency are checked before compounding.
4. Humidity and temperature should be maintained during the manufacturing, filling, polishing and packaging of the capsules.

• Relative Humidity –   Less than 45 %
• Temperature –   25 ⁰C ± 2 ⁰C

5. The total weight of blended powder should be checked in the presence of Assistant Manufacturing Chemist and record the same in Batch Manufacturing Record.
6. Bulk sample should be sent for analysis to Quality Control Department before starting the filling of hard gelatin capsules.
7. Intermittently the Assistant Manufacturing Chemist should check weight variation of filled capsules at interval of 30 minutes and record for the same should be kept in Batch Manufacturing Record.
8. Detect out of limit capsules by Weight Variation Method as follows:
9. Take the average weight of 20 Capsules on the calibrated balance and calculate the upper and lower limit as per the table given below in accordance with IP/BP:

•  Take the weight of individual Capsules and check if all the Capsules are lying with in the limits.
•  Select the Capsules only if no more than two Capsules are out of percentage limit and if none Capsule differs by more than 2.5 times the percentage limit, otherwise reject the Capsules.Capsules taken for testing and In-process control should not be added to the bulk batch to avoid mix-ups and  cross-contamination.
• Inspection, sorting and polishing of filled capsules should be done as per SOP 
• Disintegration of filled capsules should be done using Disintegration Testing Apparatus
• Disintegration is the time required for the group of capsules to disintegrate. Disintegration Test should be carried out at regular interval of 1 hour by using Disintegration Test Apparatus.
• The tube assembly unit is removed from the glass beaker and from each tube the plastic discs are removed.
•  Place the capsules in each of 6 tubes along with a plastic disc over the capsules
•  The glass beaker is filled with water. The water in the beaker is retained at the temperature of 37+1˚C through out the test by suitably setting the thermostat.
• Introduce a tube assembly unit into glass beaker in such a way that wire mesh at the base of each tube is atleast 2.5cm below the surface of liquid when the basket is at highest position.
•  Switch on the apparatus to move the basket assembly containing the capsules up and down through a distance of 5 to 6 cm at a frequency of 28 to 32 cycles per minute. Start the stopwatch.
• When the capsules have disintegrated i.e. when no particles remain on the wire mesh at the bottom of tube, stop the stopwatch. Note the time taken for disintegration of the capsules and record the same in Batch Manufacturing Record.
• Disintegration Time of filled capsules = Not more than 15 minutes
• The strips and cartons should be checked thoroughly for proper batch coding.
• Assistant Manufacturing Chemist and Production Pharmacist should randomly check that the correct no. of strips are being packed in each cartons and also the number of cartons in each shipper is exactly the same as that shown in proof.
• Intimation should be sent to Quality Control Department for finished product sampling and testing.
• After the completion of labelling and packaging, the coded cartons should be accounted for and rejected printed material should be destroyed in the presence of QC/QA Manager. Fill the destruction sheet and attach the same in the Batch Manufacturing Record.
• It will be ensure that filling or packaging equipment has been properly cleaned after the completion of batch.
• Filling or packaging of next product should not commence until the Quality Control Analyst has given the ‘Line Clearance’.
