Pharmaceutical Granulation Processes, Mechanism, and the Use of Binders 271 where g is the surface tension of the liquid, q the contact angle, and r is the radius of the capillary. The preformulation has demonstrated superior solubility and dissolution rate of the lipid lowering statin drug as compared to the marketed lovastatin product. In preformulation, IR can be specially used to determine polymorphism of solid crystals as well as for drug – excipients compatibility study. World Health Organization. preformulation study should start at a point, after Preformulation involves the application of bio biological screening of the drug when a decision pharmaceutical principles to the physic chemical is made for further development of the compound parameters of … 3b. The University of Iowa Pharmaceuticals (UIP) has the capability to systematically build quality into products from inception by performing various pharmaceutical preformulation studies. These studies should focus on those physicochemical properties of the new compound that could affect drug performance and development of an efficacious dosage form.
