3. Quality Standards & Regulatory Compliance

The vendors supplying API for Promacta must meet rigorous regulatory criteria. Regulatory authorities require API suppliers to be cGMP-compliant, with documented process validation, impurity control, stability, and traceability.

Key considerations include:

• GMP Certification: Ensures manufacturing processes adhere to internationally recognized standards.
• Quality Control Testing: API batches should pass tests for assay purity, residual solvents, heavy metals, and microbial contamination.
• Regulatory Documentation: Certificate of Analysis (CoA), Stability Data, and Regulatory Filings.

Manufacturers must validate supplier quality through audits, inspections, and ongoing quality assessments to mitigate risks of supply disruptions or subpar quality.
