— WHY IS THIS NEEDED?
Combination of Amoxicillin (penicillin) + Clavulanic Acid (beta-lactamase inhibitor):
• Clavulanic acid is chemically unstable, degrades rapidly with moisture and heat
• Amoxicillin can form high molecular weight polymers (protein-antibiotic conjugates), which are potent allergens
• Strict ratio of components required for efficacy (typically 2:1, 4:1, 7:1)
• Moisture control critical for shelf life
⚠️ CRITICAL:
• Amoxicillin Content: 95–105%
• Clavulanic Acid Content: 90–110% (wider range allowed due to instability)
• Amoxicillin Polymer: ≤ 0.05% (strict! anaphylaxis risk)
• Clavulanate Degradation Products: ≤ 1.0%
• Moisture (LOD/KF): ≤ 2.0–2.5% (exceedance leads to rapid clavulanate decomposition during storage)
• Dissolution: ≥ 80% for both components
• Microbiology: absence of pathogens, limits for TAMC/TYMC
⚠️ Note: Utility places special emphasis on clavulanate stability. Exceeding moisture or clavulanic acid degradation products is a common cause of batch rejection for penicillins with inhibitors. Amoxicillin polymer check is mandatory for all penicillins due to cross-allergy risk.

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.
