- Water Type
- Sterile water
- Bacteriostatic water (0.9% benzyl alcohol)
- Bacteriostatic water
- Bacteriostatic water prevents bacterial growth during multi-dose use. Sterile water supports contamination within 48 hours
- Mixing Temperature
- Room temp (20–25°C)
- Controlled 20–22°C
- Temperature control during reconstitution prevents thermal shock that reduces dissolution uniformity
- Target Concentration
- Variable
- 1–2 mg/mL
- Concentrations above 3 mg/mL increase aggregation; below 0.5 mg/mL accelerate surface adsorption loss
- Storage Container
- Clear glass
- Amber glass
- Amber glass, aliquoted
- Amber glass blocks photodegradation; aliquoting prevents repeated freeze-thaw cycles
- Storage Duration
- 14 days at 2–8°C
- 28 days at 2–8°C
- 6 months at −80°C (single-use aliquots)
- Standard refrigeration supports 28 days; ultra-low freezing extends stability but requires single thaw
- Administration Route
- Subcutaneous (abdominal)
- Subcutaneous absorption provides consistent pharmacokinetics; IM injection introduces variability
