The book on Wildlife Drug Formulatory and Critical Care Management provides the updated basic information about fundamentals of different pharmaceutical agents and the disorders of different system in which they are used. Book coveres basic aspects of the various topics which will be very useful for veterinarians working in forest, zoos or at field level where they use to get wild animals for various ailments and thereafter for treatment. It will also provides helpful information to the forest officers, zoo managers and protected area managers for critical care management and for doing needful things before approaching a veterinarian to save the life of animal or to collect biological material useful for diagnosis. The introductory chapters of the book covers base line information about various pharmacological agents based on their chemistry, mode of action, categories, uses, indication, contrindications, drug action,precautions, special care while using the compound and their dosage in diffferent wild species. The second part of the section in this book provides basic information for handling the emegencies as well as indices for critical care and management of animals with vital parameters and glimpses of emergency drugs, dosages, and indications in different wild species. The tabulatory indices for major wild species are also covered with different heading of major compounds. I am sure that this book will encourage and provide plateform for the veterinarians who donot have the base line informations about the uses of various pharmaceutical compounds used in captive and free living wildlife health care and management. It will be boon for the undergraduate and post graduate students of veterinary, zoo veterinarians and veterinarians working in protected area management as well as to many more that loves wild animals and do little for their conservations. I am very grateful to all who directly or indirectly supported me for this outcome.
