Antacid and it mechanism of action

Antacid and it mechanism of action

Calcium carbonate is an ionic compound used as a calcium supplement or antacid used for the symptomatic relief of heartburn, acid indigestion, and sour stomach.

Mechanism of action

Aluminum hydroxide is a basic inorganic salt that acts by neutralizing hydrochloric acid in gastric secretions. Aluminum hydroxide is slowly solubilized in the stomach and reacts with hydrochloric acid to form aluminum chloride and water. It also inhibits the action of pepsin by increasing the pH and via adsorption. Cytoprotective effects may occur through increases in bicarbonate ion (HCO₃^–) and prostaglandins.

 Packing Details: 

1.Wash the bottles on Linear Bottle Washing Machine L-24 and operate it as per its SOP.

2.Transfer the Suspension from storage tank to Digipack Bottle Filling and Sealing Machine L-25 for filling and then sealing of the bottles as per its SOP.

3.Fill 160 ml suspension in 170 ml white glass bottle and use 25 mm PP Cap to seal the bottle mouth.

4.Inspect each filled and sealed bottle for proper sealing and presence of the foreign particles, if any.

5.Label every inspected bottle by using the Automatic Bottle Labelling Machine L-26 as per its SOP.

6.Pack 36 filled and sealed bottle in each corrugated box  A-01.

7. Seal each corrugated box with adhesive tape and label it properly by affixing the specified label.

MANUFACTURING PROCESS:

1. Charge 240 kgs of Sorbitol to charging tank.

 Addition of Ingredients into the Charging Tank L-09 while stirring continuously:       

2.Dissolve 8.0 kgs of Sodium Benzoate in 50  Ltrs of  DM water and add to the bulk batch.

3.Dissolve 1.60 kgs of Aspartum  10 Ltrs of  DM water and add to the bulk batch.

4.Slowly transfer 924.0 kgs of Aluminium Hydroxide Paste to the bulk batch.

5. Add 200 Ltrs of Purified Water to the bulk batch.

6.Slowly transfer 140.8 kgs of Magnesium Hydroxide Powder to the bulk batch.

7. Add 1.6 kgs of Aerosil to the bulk batch.

8.Dissolve 1.28 kgs of Bronopol in 5 Ltrs of DM water and add to the bulk batch.

9.Slowly transfer 16.8 kgs of Simethicone to the bulk batch.

10.Dissolve 0.560 kgs of Tartrazine Supra in 5 Ltrs of Purified water and add to the bulk batch.

11.Mix the whole batch for 1 hour and then colloid the batch.

12. Colloid the batch through Colloid Mill L-20 by operating it as per  its SOP and transfer it to the Charging Tank.

13.Dissolve 0.512 kgs of Menthol in 16 x 450 ml of Spirit Chloroform and add to the bulk batch.

14.Make up the volume with DM water to 1600 Ltrs and mix until homogeneous.

15.Leave the Suspension to settle for overnight or for minimum 8 hours.

16. Again check the volume and make up with DM water to 1600 Ltrs and mix until homogeneous.

17. Check the self pH of Solution to be in between 8.0 – 9.0

18.Send the sample to Quality Control Department for bulk testing.

19.Transfer it to the Storage Tank.

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  Manufacturing Chemist. If any discrepancy is noticed, it should be immediately brought to the notice of Production and QC/QA Manager.
3. Physical characteristics of Raw material like colour, odour, and consistency are checked before compounding.
4. Final volume should be made as per Standard Operating Procedure using correct dipstick in the  Manufacturing Chemist.
5. pH of the bulk should be checked and it should be with in specified limits.
6. Bulk sample should be sent for analysis to Quality Control Department before starting the filling and sealing stage.
7. Intermittently filled volume should be checked at 30 minutes interval by the Assistant Manufacturing Chemist and record for the same should be kept in Batch Manufacturing Record.
8. The net volume should be checked for all the filling nozzles and in no case, net volume should be less than   volume claimed on the label.

1. Limit for Volume Variation  :  Volume claimed on the label + 2ml
2. Visual inspection of filled and sealed bottles should be done as per SOP and the record of the same should be kept in the Batch Manufacturing Record.
3. Suspensions should be filled under constant slow speed stirring to maintain uniformity of contents.
4. The labels and cartons should be checked thoroughly for proper batch coding.
5. Intimation should be sent to Quality Control Department for finished product sampling and testing.

1. After the completion of labelling and packaging, the coded labels and cartons should be accounted for and rejected printed material should be destroyed in the presence of QC/QA Manager. Maintain the destruction of the same in the Batch Manufacturing Record.

1. It will be ensure that filling or packaging equipment has been properly cleaned.

1. Filling or packaging of next product should not commence until the ‘Line Clearance’ has been given by the IPQA.
