IMPORTANCE OF PREFORMULATION STUDIES IN DESIGNING FORMULATIONS FOR SUSTAINED RELEASE DOSAGE FORMS G.Sahitya*, B.Krishnamoorthy, M.Muthukumaran Montessori Siva Sivani Institute of Science & Technology-College of Pharmacy-Vijayawada. 04/05/2012 KLE College of Pharmacy, Nipani. Definition:- Preformulation Considerations is the investigation of physico-chemical properties of the new drug compound that could affect drug performance and development of an efficacious dosage form”. pharmacy … Introduction • The preformulation is the first step in the rational development of a dosage form of a drug substance alone and when combined with excipients. It can … This is the concept of preformulation. Preformulation commences when a newly synthesized drug shows sufficient pharmacologic promise in animal models to warrant evaluation in man. pharmacy study material Antihistaminic Agents Quick Revision. Drugs can be given to a person in a variety of formulations. In the early stages of preformulation the need rapidly to determine bioavailability, dose and toxicity data predominate and hence the first formulations of a drug substance are usually for intravenous injection. 4 5. 1-41 DOI: 10.1039/9781782620402-00001 eISBN: 978-1-78262-040-2 From Book Series: Drug Discovery Trevor M.

Hand written notes PDF pharmatech study material. A pharmaceutical formulation is composed of several formulation factors and process variables. Category : pharmacy. ABSTRACT: Preformulation is a group of studies that focus on the physicochemical properties of a new drug candidate that could affect the drug performance and the development of a dosage form.This could provide important information for formulation design or support the need for molecular modification. 1.2 Assay design. Formulations is a mixture in a particular state that the drug is supplied to the patient. Preformulation study is there for the multidisciplinary approach and utilizes involvement of several aspects of pharmacology, toxicology, clinical pharmacy, biochemistry, medicinal chemistry, and analytical chemistry .

PREFORMULATION It is defined as the phase of research and development in which preformulation studies characterize physical and chemical properties of a drug molecule in order to develop safe, effective and stable dosage form.
