Subject: Formulation science pharma. Formulation ScienceThe formulation of a drug compound, i.e. the way in which is it combined with excipients (such as: binders, diluents, solubilizers and disintegrants) in, for example, tablets, capsules, creams pastes and gels can be critical to the performance of the active ingredient. The formulation must also be fully characterized to ensure product efficacy and patient safety. Techniques used for characterization include X-ray crystallography, vibrational spectroscopy, thermal analysis, solid state NMR and microscopy. Polarized light microscopy, in particular, can be used to study a wide range of physicochemical properties. Materials can be characterized and identified by optical properties such as refractive index and birefringence and other phenomena such as particle size, particle shape, color, twinning and the presence of inclusions or contaminants.
