Combination Drug Delivery Approach as an Effective Therapy for Various Diseases explores the use of bioengineering tools in combination drug delivery approaches to control various diseases at different clinical stages of synergistic action, varying mechanisms of action, and during the suppression of drug resistance. The book presents fundamental knowledge on the experiential and experimental aspects of drug combination approaches in order to equip rational applications in preventing the emergence of resistance during the treatment of various diseases. It provides a holistic understanding of the principles behind formation, characterization, applications, regulations, toxicity, challenges and future perspectives of combination drug delivery approaches. It will be of interest to researchers and advanced graduate students in pharmaceutical science, chemistry, biology and medicine, as well as pharmaceutical companies and scientific organizations.
