The contents of this course have been meticulously designed to provide fundamentals of various disciplines embodying pharmaceutical drug analysis specifically for the under-graduate students. It will also be useful to the graduate students studying modern methods of pharmaceutical analysis to a great extent. Particular emphasis has been laid on the pharmaceutical substances that are specially found in the Official Compendia. It will also cater to scientists and investigators, working in other fields of pharmaceutical sciences who wish to update their personal wealth of knowledge and understanding of the intricacies of modern methods of Pharmaceutical Drug Analysis. Another aim is to teach the students the special care and attention that should be given to the analysis of bioactive compounds with narrow safety margin and pharmaceutical products containing them. Furthermore, purity and stability control, determination of active materials, excipients and additives should be studied. Statistical processing of results, study of the reliability of the applied methods and evaluation of results obtained by various methods and validation of chromatogram quality are aims, too. It is also valuable for the students to provide the knowledge of methods described in Pharmacopoeia application of the mentioned methods in the analysis of pharmaceutical formulations and biological fluids, efficiency of packaging material for pharmaceutical products (protection from air, light, humidity) and contamination of the products by the packaging materials are also aims of this course. Enough literature has been cited at the end of each chapter under ‘Recommended Readings’ so as to enable the reader to follow up a particular topic with ease.
