Pharmaceutical preformulation and formulation pdf
Миръ Искусства. Томъ 8 [7 8]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.

Probably at least a year will have passed by the time bioavailability studies are completed and stability studies produce meaningful long term results, during which time rival manufacturers will have been developing their own products. So how can a manufacturer increase the probability that a particular formulation will be successful in terms of consistent quality and regulatory compliance? Answer by - conducting a thorough review of relevant scientific literature and by undertaking preformulation studies. Systematic preformulation studies on the active pharmaceutical ingredient API and on pilot formulations attempt to predict the viability of various formulations and methods of manufacture. These studies give clues as to how to achieve the desired performance of the finished product.
