(2011) Pharmaceutical Preformulation Studies—Current Review. 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. A Review on Pharmaceutical Preformulation Studies in Formulation and Development of New Drug Molecules. Another approach used in developing such tablets is maximizing pore structure of the tablets. The tablet manufacturability and performance are dependent, among other things, on the physicochemical properties of the drug substance. Preformulation is defined as an investigation of physical and chemical properties of a drug substance alone and along with excipients before the formulation. 4 | Issue No.4 | 2311-2331 Page 2312 Introduction Almost all drugs are marketed as tablets, capsules or both. This could provide important information for formulation design or 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. The main objective of pre-formulation testing is to generate information useful to the formulator in developing s table and bioavailable dosage forms before formulation development. Preformulation studies help in assessing the ‘drug ability’ of a molecule. Composition of core tablets. Identifying the material properties at an early stage which will become Critical Quality Attributes of the product Preformulation studies 1. The basic approach used in development of mouth dissolving tablets is the use of superdisintegrant, which provide forms (tablets) and, is in its crystalline form,generally considered to be least reactive.
