— WHY IS THIS NEEDED?
Ibuprofen + Paracetamol combination — popular OTC analgesic:
• Ibuprofen is poorly soluble in water, so its release rate is critical for rapid onset of action
• Paracetamol has toxic impurity PAP (p-aminophenol), limit is extremely strict (0.005%)
• Ibuprofen has specific synthesis impurities (related compounds A, B)
• Synchronous dissolution of both components ensures comprehensive analgesic effect
• Content uniformity important for dose stability
⚠️ CRITICAL:
• Content of both APIs: 95–105%
• PAP (Paracetamol): ≤ 0.005% (toxicity)
• Ibuprofen Impurities: ≤ 0.2% each, total ≤ 0.5%
• Uniformity (RSD): ≤ 6.0%
• Dissolution: ≥ 80% in 30 min for both components (especially important for ibuprofen)
• Microbiology: absence of pathogens
⚠️ Note: Utility focuses on ibuprofen release speed. Slow dissolution will lead to delayed pain relief. PAP control critical due to risk of liver and blood damage. Combination allows lowering dose of each component compared to monotherapy, reducing side effects.

TC-001Valid CSV with expected header and sample rowAll rows are processed; output contains PASS/WARNING/FAIL and parameter-level detail.
TC-002A mandatory input.csv column is missingImport is rejected or the row receives FAIL with schema reference.
TC-003A numeric field contains text or a blank valueType conversion error is recorded; the result is not hidden as PASS.
TC-004A parameter is outside specification or critical limitCritical parameters produce FAIL; non-critical deviations produce WARNING according to the rule.
TC-005Positive pathogen/microbiological flag or microbiological limit excursionCritical FAIL is produced with the offending parameter.
TC-006Insufficient dissolution or excessive disintegration timeFAIL/WARNING is produced according to method criticality.

10. QA/QC, CSV and change control

  • Before production use, the client records executable version, checksum, specification/monograph version, test CSV, expected JSON and IQ/OQ results.
  • Column names must not be changed without updating the validator and test scenarios.
  • The source CSV, output.json and utility version should be stored together as an evidence package.
  • Any change in control rules must go through change control and repeated OQ scenario verification.
