The word “drug” is derived from the old French word “drogue” which means a “dry herb”; and has often been used interchangeably with “medicine”, “pharmaceutical product” and “pharmaceuticals” to refer to chemical substances intended for use in the diagnosis, prevention, treatment an… Such studies are critical to drug and drug product design. A key article that discussed advantageous property values commented: “Drug-like is defined as those compounds that have … Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Physicochemical Property of New Drug Molecule - authorSTREAM Presentation. See our User Agreement and Privacy Policy. Physicochemical properties of drug molecules: Refractive index, optical rotation, dielectric constant, dipole moment, dissociation constant, determinations and applications: To study various physicochemical properties and flow properties of drug molecules in the designing of dosage form Physical pharmacy and biopharmaceutics is the study of the relationship between the physical chemical and biological properties and the fate of a drug in vivo, in order to design an optimized dosage form. The use of nanotechnology to optimize the delivery of drugs and diagnostic molecules is increasingly receiving attention due to the enhanced efficiency provided by these systems. Describe the distribution of a drug from the plasma to the interstitia of tissues, including the influences of a drug's physicochemical properties, and of binding to plasma proteins and to tissue components. Drugs are substances other than nutrients or essential dietary ingredients, which when administered to a living organism, influences biological functions. Serve as quality control procedures, once the form of drug and its formulation have been Professor 2. ��ࡱ� > �� _ a ���� | } ~  � � � � � � � � � � � � � � ` u ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������`!�| Slide 5: Why is Preformulation Important ?

These polymorphic forms of a drug differ in the physicochemical properties like dissolution and solubility, chemical and physical stability, flowability and hygroscopicity. The choice of drug candidates for permeation through the skin must be based on several factors, including physicochemical properties, drug interactions with the membrane, and pharmacokinetic considerations. UNIT-III : Surface and interfacial phenomenon . You can change your ad preferences anytime. It is often surprising that analytical chemists cannot distinguish between, for instance, basic, weakly basic, acidic, weakly acidic and neutral nitrogen functions. �c��B��FE�∏z�R���Ӣ7�������0�Kh������y|��9�7��% m� ȂzpK(��wE�^>��t&I�+��w�����. When a promising new chemical entity is synthesized, it needs transformation to appropriate formulation in order to show a better and desirable action at appropriate site.
