RSSL offers pre-formulation services to screen for major drug candidates and helps you understand their stability and behaviour ahead of clinical trials.


The key goal of the pre-clinical stage is to understand your drug molecule’s behaviour and stability. This step is paramount to ensure the viability of drug candidates that proceed to clinical trials. We can conduct stability studies to help you further understand your molecule of interest and prepare for the clinical phase. 


The broad experience and expertise of our scientists, in particular our physical chemists who conduct detailed powder flow and particle size analysis, means we can provide support with developing formulations as well as pre-formulation screening.


To support your pre-clinical phase, we can offer Forced degradation studies, to understand how the molecule breaks down and to identify all possible molecular changes as well as analytical methods to identify and understand molecular impurities and safety.
