Development of tablet dissolution methods is naturally based on compendial instruments e.g. paddle/basket, in order to transfer them easily to QC.

However dissolution profiles have to be discriminant and specific developments have always been made around the compendial instruments, based on specific drug dosage forms evolution  (stents, microspheres...) or drug specificities: poorly soluble compounds, low concentration drugs.

The permanent evolution of the drug delivery systems requires, continuously, new instrument developments to investigate and modelize specific release mechanism e.g. here : diffusion and convection cell without membrane for topical and parenteral products.

SPS Pharma Services uses and will always use state-of-the-art dissolution instruments to provide its customers the best Dissolution screening available at that time.
