Pharmacokinetics PDF Free Download by Sunil S Jambhekar

Pharmacokinetics is another very famous book on Pharmaceuticals. Pharmacokinetics PDF by Sunil S Jambhekar, Dr Philip J Breen offers information about new developments in the pharmacokinetic field. You can download the 2nd edition in pdf format for free.  Pharmacokinetics is the study of the time course of absorption, distribution, metabolism, and excretion of a drug. It also refers to the relationship of these processes with the intensity and time course of the pharmacological (therapeutic and toxicological) effects of drugs and chemicals. Pharmacokinetics is a quantitative study that requires pre-existing proficiency in mathematics at least through calculus. It is also a biological study and can be very useful for biomedical scientists. At a fundamental level, pharmacokinetics is a tool for optimizing the design of biological experiments with drugs and chemicals. All biologists would benefit from some knowledge of pharmacokinetics whenever they are involved in data analysis. It has become increasingly important in the design and development of new drugs and in the re-evaluation of old drugs. Clinical applications of pharmacokinetics have resulted in improvements in drug utilization and direct benefits to patients.

There is consensus that the origin of pharmacokinetics can be traced back to two articles entitled “Kinetics of Distribution of Substances Administered to the Body” written by Torsten Teorell and published in the International Archives of Pharmacodynamics in 1937. From this unexpected beginning, the study of pharmacokinetics has matured rapidly; Growth has undoubtedly been stimulated by major advances in analytical chemistry, which allow us to quantitatively detect minute concentrations of drugs and chemicals in extremely small volumes of biological fluids, in data processing, and by the insights of many scientists. Dost, Kruger-Theimer, Nelson, Wagner, Riegelman, and Levy are among these scientists, and a special place must be reserved for them in the history of the development of pharmacokinetics.

Our goals in preparing this review were similar to those that prompted us to undertake the initial effort. The need for revision was very clear to us every time we looked at our archives, replete with research papers and commentaries on pharmacokinetic methods and applications published since 1975. The buzzwords today are clearance concepts, non-compartmental models, and physiological pharmacokinetics. . Once again, we strive to present the material in an explicit and detailed manner. We continue to believe that pharmacokinetics can be used in formal courses, for self-study, or for reference. We thank our colleagues for their work and publications, our staff for their work and support, and our families for their love and understanding.

Use of drugs in disease states

The use of medicines to treat or improve diseases dates back to the dawn of history. Since the drugs are xenobiotics, meaning compounds that are foreign to the body, they have the potential to cause harm rather than cure, especially when used inappropriately or at the wrong dose for the individual patient being treated. So what is the correct dose? The medieval physician/alchemist Paracelsus declared: “Only the dose makes a thing, not a poison.” This implies: “The dose of a drug is enough, but not too much.” The objective of this text is to present some tools to enable the determination of the appropriate dose: a dose that will be therapeutic but not toxic in an individual patient, possessing a particular set of physiological characteristics.

At the same time that the disciplines of medicine and pharmacy strive to use existing medicines in the most effective way, scientific researchers are engaged in the process of discovering new medicines that are safe and effective and that are significant additions to our arsenal. for the treatment or prevention of diseases. This process is increasingly time-consuming, expensive, and often frustrating. Here are two statistics on new drug approvals:
  • the average time for a new drug to be approved is 7 to 9 years
  • the cost of introducing a new drug is approximately $700 million to $1 billion.

Steps involved in the drug development process include:

1. The pharmacologically active molecule or drug entity must be synthesized, isolated, or extracted from a variety of possible sources (drawing on the disciplines of medicinal chemistry, pharmacology, and toxicology).
2. Formulation of a dosage form (i.e., tablets, capsules, suspension, etc.) of this drug must be done in a manner that delivers the recommended dose to the “site of action” or target tissue (employing the principles of pharmacy physical and pharmaceutical).
3. A dosage regimen (dose and dosage interval) must be established to provide an effective concentration of a drug in the body, as determined by physiological and therapeutic needs (using pharmacokinetics and biopharmaceuticals).
