This could provide important information for formulation design or support the need for molecular modification. Every drug has intrinsic chemical and physical properties which has been consider before development of pharmaceutical formulation. View PDF. Save to Library.
Preformulation starts when a newly synthesized drug shows sufficient pharmacological action in animal model to warrant evaluation in man. It should focus on those physicochemical properties of the new compound that could affect drug performance and development of dosage form. It provides a rationale for formulation design or support the need for molecular modification. If deficiency is detected, then it should be decided on the molecular modification that would most likely improve the drugs properties. Major area of preformulation research: I. Stability Analysis - Solution stability - Solid state stability - Bulk stability - Compatibility Crystallinity and polymorphism Crystal habit: It is the description of the outer appearance of a crystal. Internal structure: Molecular arrangement within the solid.
