the manufacturer or as specified in the product monograph. Temperature-controlled storage areas may be required for materials sensitive to temperature fluctuations.

Humidity Control: Humidity levels in storage areas should be controlled to prevent moisture absorption by hygroscopic materials, which can lead to changes in quality.

Light Protection: Materials sensitive to light should be stored in containers that provide protection against exposure to light.

2. Segregation

Raw materials should be segregated based on their compatibility and specific storage requirements. Incompatible materials should not be stored together to avoid the risk of cross-contamination or chemical reactions that may compromise the quality of the materials.

3. Good Inventory Management

Effective inventory management is crucial to prevent the use of expired or deteriorated raw materials. A first-in-first-out (FIFO) approach should be followed to ensure that older materials are used before newer ones.

4. Handling Procedures

Raw materials should be handled carefully to avoid physical damage or contamination. Proper procedures should be followed during receiving, sampling, dispensing, and weighing of materials. The use of appropriate equipment, such as calibrated weighing balances, helps ensure accuracy during handling.

5. Labeling and Identification

Each container of raw material should be properly labeled with essential information, including the name of the material, batch or lot number, expiration date, and storage conditions. Clear identification prevents mix-ups and ensures the use of the correct material in production.

6. Pest Control

Measures should be in place to prevent pests from entering storage areas and contaminating raw materials. Regular pest control activities and maintaining a clean environment contribute to effective pest control.

7. Quality Control Testing

Raw materials should undergo quality control testing to verify their identity, purity, and potency. Only materials that meet the established specifications should be used in manufacturing.

8. Documentation

All activities related to the storage and handling of raw materials should be documented. This includes recording storage conditions, receipt and issuance of materials, and any deviations or incidents encountered during handling. Documentation provides an audit trail and supports compliance with Schedule M requirements.

Conclusion

Adhering to the guidelines for storage and handling of raw materials under Schedule M is essential to ensure the quality and safety of pharmaceutical products. By maintaining appropriate storage conditions, segregating materials based on compatibility, following good inventory management practices, and implementing proper handling procedures, pharmaceutical manufacturers can prevent quality issues and ensure that raw materials meet the necessary specifications for use in production.
