Preformulation can help in cost cutting for effective therapeutic development of the product. List reasons for the incorporation of drugs into various dosage forms 2. 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. It can be defined as an investigation of physical and chemical properties of a drug substance - alone and when combined with excipients. This article focuses on preformulation testing for oral solid dosage forms in a drug discovery setting. Solid dosage form E.g. Present work will establish the ability of lactose as an excipient to be the choice of candidate while developing formulation having poor flow API using direct compression process. Insoluble or unstable drugs slow down the approval of drugs. technology).
