Liposomal Manufacturing
Expertise
Applied understanding of lipid-based systems:
how they assemble, behave and respond to real manufacturing conditions.
Designed to support controlled, reproducible liposomal production at commercial scale.
Liposomal Encapsulation
Liposomal systems are lipid-based vesicular structures formed through the self-assembly of phospholipids in aqueous environments.
Their behaviour is governed by multiple interdependent variables, including:
⇒ Lipid composition and phase behaviour
⇒ Processing conditions (e.g. temperature, energy input, mixing)
⇒ Environmental factors (pH, ionic strength, storage conditions)
Critical liposomal performance characteristics include:
⇒ Particle size distribution and polydispersity index (PDI)
⇒ Encapsulation efficiency and payload retention
⇒ Dispersion stability over time
As a result, stability and structural consistency depend not only on formulation design
but on how systems are processed, handled and scaled.
Liposomal formats:
liquid and solid-state systems
Liposomal systems are inherently formed in aqueous environments; however, commercial applications often require formats that extend beyond simple liquid dispersions.
GMPriority Pharma supports:
- Hydrated liposomal systems for direct dispersion and formulation integration
- Solid-state liposomal formats engineered for defined storage, transport and downstream processing conditions
Dry liposomal systems are produced through controlled dehydration processes (e.g. spray drying or lyophilisation), designed to preserve vesicle structure and enable reproducible reconstitution.
Liposomal systems are evaluated using physicochemical and structural characterisation techniques to assess:
Ξ Particle size distribution and polydispersity index (PDI)
Ξ Dispersion behaviour under defined conditions
Ξ Stability across defined storage environments
Understanding how lipid systems respond to processing, drying and scale-up conditions is critical to maintaining structural integrity during manufacture.
Characterisation data is used to define acceptable parameter ranges and support reproducible processing across development and production.
Structural characterisation
Where liposomal systems typically fail
Liposomal formulations often perform well at laboratory scale but fail during scale-up due to:
- Uncontrolled particle size distribution and high PDI
- Instability under processing or storage conditions
- Sensitivity to changes in energy input, temperature or concentration
- Loss of encapsulation efficiency during manufacturing
How GMPriority Pharma addresses this
- Early definition of critical formulation and process parameters
- Integration of development and manufacturing constraints
- In-process control of particle size distribution and dispersion behaviour
- Structured verification of batch-to-batch consistency
Applied manufacturing expertise
Scientific understanding is integrated directly into manufacturing execution to support:
- Defined particle size distribution across batches
- Controlled process conditions influencing vesicle formation and stability
- Reproducible batch output within defined parameter ranges
- Reliable commercial supply under GMP-aligned systems
Scientific Authentic Innovative Formulation
Rather than treating formulation and manufacturing as separate stages, GMPriority Pharma aligns development parameters with production constraints from the outset.
Our focus is not on theoretical encapsulation,
but on producing liposomal systems that maintain defined structure and performance under real manufacturing and commercial conditions.
