This book has evolved over the last twenty years from a cumulative effort to develop a professional course in pharmacokinetics that would assist future practitioners in therapeutic decision making. As practicing pharmacists become more involved with patient advising, it becomes apparent that clinicians will be required to make dosing adjustments for certain drugs. This will become increasingly... Read more
