In addition to the difficulty and dense information content of Pharmacology courses in undergraduate education, it is necessary to learn and internalize the topics of “General Pharmacology” well in order to break free from the effects of the rote learning system and to be able to interpret existing pharmacology knowledge within the framework of “personalized medicine” and “rational drug use.” The result of intensive work, this book has been enriched with current literature to ensure it has the quality and content to meet the information needs at both the undergraduate and postgraduate/academic levels. Clinical examples are frequently used to facilitate a better understanding of general pharmacology topics, and visuals and tables are used to make the content easier to understand.
