Pharmaceutical Method Development
- for Solid-State Characterization
Pharmaceutical Method Development
At Particle Analytical, we specialize in developing robust analytical methods for solid-state characterization under GMP conditions, ensuring reliable and reproducible results that support drug development, manufacturing, and regulatory submissions.
What is Pharmaceutical Method Development?
Pharmaceutical method development is the systematic process of designing and optimizing analytical methods to characterize the physical and solid-state properties of pharmaceutical materials, including drug substances, excipients, and drug products.
These methods are used to accurately measure critical material attributes such as:
- Particle size distribution (PSD)
- Subvisible particle content
- Polymorphic form
- Crystallinity
- Morphology
- Surface area
- Density and flow properties
Key Stages of Pharmaceutical Method Development
Method development evolves alongside drug development and manufacturing.
Early-Stage Development
Initial methods are developed to characterize solid-state properties of APIs and excipients, including polymorphism, crystallinity, and particle size.
Clinical Development
Methods are optimized to ensure reproducibility and robustness, supporting formulation development and regulatory submissions.
Commercial Manufacturing
Fully optimized and validated methods are implemented for routine quality control, batch release, and stability studies.
Particle Analytical supports method development throughout the entire pharmaceutical lifecycle.
Analytical Techniques Used in Pharmaceutical Method Development (Solid-State)
At Particle Analytical, we develop and optimize analytical methods using advanced solid-state characterization techniques, including:
- X-ray Powder Diffraction (XRPD) – polymorphism and crystallinity
- Raman spectroscopy and Raman mapping – polymorph and particle identification
- Dynamic Light Scattering (DLS) – nanoscale particle characterization
- Laser diffraction – particle size distribution
- Light Obscuration Particle Counting (LOPC) – quantification of subvisible particles in suspensions, injectables, and other pharmaceutical products
- Scanning Electron Microscopy (SEM-EDX) – particle morphology and elemental composition
- Differential Scanning Calorimetry (DSC) – thermal behavior and crystallinity
- Thermogravimetric Analysis (TGA) – thermal stability and composition
- BET surface area analysis – surface properties
- Density and flowability testing – bulk, tapped density and powder flow
These techniques allow us to develop robust, reliable methods tailored to each product and application.
Challenges in Pharmaceutical Method Development ( Solid-State)
Developing reliable solid-state methods requires deep expertise due to material complexity.
Challenges may include:
- Polymorphic transitions
- Particle agglomeration
- Sensitivity to humidity or temperature
- Variability in raw material properties
Our expertise ensures robust methods capable of accurately characterizing even complex pharmaceutical materials.
