Drug delivery encompasses the methods, manufacturing processes, technologies, formulations and storage systems used to transport a pharmaceutical compound to its target site in order to produce the intended therapeutic effect. Its goal is to modify a drug's specificity and pharmacokinetics by formulating it with various medical devices, excipients and drug carriers. Drug delivery techniques that are frequently utilized include controlled, targeted and steady drug delivery. Since the introduction of systems of medical applications, a variety of drugs are being used to treat a number of diseases through the administration of various conventional forms of drug delivery, including lotions, ointments, suppositories, solutions, pills, mixtures, pastes, powders, tablets, etc. The three main mechanisms of drug delivery are swelling, diffusion and erosion. This book aims to understand the evaluation, formulation and mechanisms of drug delivery. It covers in detail some existent theories and innovative concepts revolving around this domain. Those with an interest in this field of study would find this book helpful.

Drug delivery is the method or process of administering a pharmaceutical compound to achieve a desired therapeutic effect in humans or animals. Medicines are usually administered through oral and intravenous routes. However, nasal and pulmonary routes of drug delivery are also being used increasingly for the treatment of human diseases. For ensuring that the drugs and drug delivery are efficient and safe, and that the patients do not experience any discomfort, various aspects of drug delivery, namely, principles associated with drug preparation, site-specificity, route of administration, toxicity, and metabolism are taken into consideration. Controlled or modified-release formulations have the potential to alter the rate and timing at which a drug is released into the bloodstream of the patient. This helps to produce adequate or sustained drug concentrations. This book covers in detail some existent theories and innovative concepts revolving around drug delivery. Its aim is to present researches that have transformed the theoretical and practical aspects of this discipline and aided in its advancement. For all those who are interested in this area of study, this book can prove to be an essential guide.
