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.

IN-PROCESS CONTROLS:
The following in-process controls should be maintained during the processing:
- Check Raw materials used for manufacturing purpose are all approved materials and have ‘Released’ labels fixed on it.
- 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.
- Physical characteristics of Raw material like colour, odour, and consistency are checked before compounding.
- Final volume should be made as per Standard Operating Procedure using correct dipstick in the Manufacturing Chemist.
- pH of the bulk should be checked and it should be with in specified limits.
- Bulk sample should be sent for analysis to Quality Control Department before starting the filling and sealing stage.
- 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.
- 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.
- Limit for Volume Variation : Volume claimed on the label + 2ml
- 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.
- Suspensions should be filled under constant slow speed stirring to maintain uniformity of contents.
- The labels and cartons should be checked thoroughly for proper batch coding.
- Intimation should be sent to Quality Control Department for finished product sampling and testing.
- 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.
- It will be ensure that filling or packaging equipment has been properly cleaned.
- Filling or packaging of next product should not commence until the ‘Line Clearance’ has been given by the IPQA.
