Drug information is something that is needed by all pharma professionals whether in practice, industry, pharmacy education or regulatory. Drug information in this title has been compiled based on their use in disorders of different body systems like gastro-intestinal tract (GIT), respiratory tract, cardio-vascular system. In the introductory section of each part, there is general discussion on different classes of drugs, which are used in the treatment of disorders of the system. Later, there is drug information on individual drugs. There are two chapters, which are not specific to system but deal with common factor, for example pain. These chapters include drugs used in pain, fever, and inflammation and anti-infective drugs. The book has been divided into eight parts. Many pharma professionals may not be conversant with medical terms, therefore, abbreviations and glossary of medical terms have been given in the beginning of the book. There are three appendices in the book. Appendix I contains the list of drugs and their FDC, manufacture and sale of which have been banned in India. Appendix II contains list of schedule X drugs for which separate licence is required for manufacture and sale. Appendix III contains list of medical devices, which have been notified as drugs by Govt. of India.
