For the study of a pharmaceutical drug product, particle characteristics (count, size and chemistry) and compound distributions (size and spatial) are among key parameters that strongly determine the quality of the product...
At least some degree of solubility in water is necessary for active ingredients in pharmaceutical products to be effective in vivo. However, as efforts to discover and synthesise new active ingredients are pursued by industrial and academic medicinal chemists, achieving sufficient aqueous solubility can often be a significant limitation to…

The majority of active pharmaceutical ingredients (APIs) are produced by crystallisation and so the phenomenon of polymorphism, whereby an organic molecule can adopt more than one crystalline form (Figure 1), is of considerable importance when trying to achieve consistent product quality during the manufacture of pharmaceutical solids and solid dosage…
