These volumes are designed to be the most complete guide to pharmacokinetics (PK) and its role in drug development. Geared toward graduate level students and scientists in the areas of clinical pharmacology and PK, the volumes will fill a gap between the academic science and the practical application of that knowledge in drug development. Volume 1 discusses the role that PK plays in selected clinical study designs, including first-time-in-man, biopharmaceuticals, and special population studies. Volume 2 details the key regulatory and development paradigms in which PK supplements decision-making during drug development.
