Quality Risk Assessment – New Product Introduction: Non-Sterile Soft Gelatin Capsules
Objective: Identify, assess, and control quality risks before commercial manufacture of a new soft gelatin capsule product.
1. Formulation Risks
- API–excipient incompatibility
- API degradation / oxidation / hydrolysis
- Fill viscosity and uniformity
- Solubility and precipitation
- Over/under-fill risk
2. Gelatin Shell Risks
- Gelatin–fill interaction
- Shell thickness & weight variation
- Brittleness / cracking / leakage
- Moisture content and drying variation
- Cross-linking → delayed drug release
3. Manufacturing Risks
- Mixing / homogenization failure
- Encapsulation machine parameter variation
- Improper sealing
- Temperature & humidity excursions
- Inadequate drying
4. Quality Control Risks
- Assay & content uniformity
- Dissolution / disintegration
- Microbial limits
- Water/moisture content
- Physical defects and leakage
5. Packaging & Stability
- Moisture / oxygen/light sensitivity
- Container–closure compatibility
- Blister/bottle protection
- Stability failure
- Shelf-life risk
6. GMP & Validation
- Process validation
- Cleaning validation
- Analytical method validation
- Equipment qualification
- Data integrity & documentation
High-Risk Focus
Leakage • Fill-weight variation • Content uniformity • Dissolution • Moisture • Microbial contamination • Shell integrity • Stability
Risk-Control Approach
Identify → Assess (Severity × Occurrence × Detectability) → Control → Validate → Monitor → Review
Key Principle:
“Quality risk assessment should be science- and risk-based, with controls established before routine commercial production.”
