Not every product requires large-scale production — but going beyond pilot or small batches often demands more infrastructure and control. For programs transitioning from Phase II to Phase III, regional launches, or low-volume commercial supply, medium batch size CDMO companies offer the perfect balance of flexibility, efficiency, and compliance.
With specialized medium batch size contract manufacturing services, these CDMOs support mid-scale production of solid, liquid, or sterile drugs under full GMP, helping you bridge the gap between development and full commercialization.
Key factors to consider when evaluating medium batch size CDMO companies include:
Batch range compatibility: Tens to hundreds of kilograms or thousands to tens of thousands of units
Flexible production lines for tablets, capsules, liquids, or injectables
Support for both clinical and commercial supply
Fast changeover and minimal downtime for dynamic production needs
Strong quality systems with validated processes and batch record generation
Tech transfer experience from small to mid-scale
Regulatory support for GMP compliance, IND/MAA/ANDA submissions
An ideal CDMO combines scalability, responsiveness, and regulatory reliability.
Top-tier medium batch size contract manufacturing services typically include:
Formulation development and process scale-up
GMP production of oral solids, liquids, topicals, or sterile injectables
Flexible batch size filling (semi-automatic or high-speed lines)
In-process controls and release testing
Packaging and serialization for regional or commercial markets
Stability testing and ICH documentation
Regulatory documentation and QA batch release
Supply chain support for regional or global distribution
These services are ideal for late-stage clinical programs, regional product launches, and low-volume therapies.
Choosing experienced medium batch size CDMO companies offers key benefits:
Cost-efficiency for targeted or specialty markets
Scalability without the overhead of high-capacity manufacturing
Reduced lead times through focused batch processing
Full regulatory alignment for inspection-ready documentation
Flexibility to handle product variability, reformulations, or multiple SKUs
These CDMOs offer agility with the quality systems and infrastructure of full-scale manufacturers.
