Clearance: Because of its implications for both dose level and frequency, clearance rate is one of the most critical pharmacokinetic parameters to be considered while designing new drug candidates. Pharmacokinetics, and pharmacodynamics are, therefore, frequently crucial determinants of a drug's efficacy and safety, and their evaluation is an important component during the preclinical and clinical development of a drug candidate. However, the potential impacts of genetic variability on the pharmacokinetics and pharmacodynamics of macrolides are important to consider as sources of interindividual differences in macrolide response.

All the study notes Pharmacodynamics with pharmacokinetics (what the body does to the drug or the fate of the drug in the body) helps explain the relationship between dose and effect, that is, the effect of the drug. Receptors • Drugs act through specific receptor (macromolecule or binding site that serves to recognize and initiate the response to a signal molecule or drug) which regulate critical functions like Pharmacokinetics, and pharmacodynamics are, therefore, frequently crucial determinants of a drug's efficacy and safety, and their evaluation is an important component during the preclinical and clinical development of a drug candidate. pharmacodynamics and the mechanism of drug action. Students will have the knowledge about the receptor and types of receptors and their examples. Following other fields in infectious diseases there has been an pharmacodynamics and pharmacokinetics (Figure 1) and these will be described in detail in parts 1 and 2 of this series respectively.

This chapter will review basic concepts related to pharmacokinetics and pharmacodynamics. The purpose of studying pharmacokinetics and pharmacodynamics is to understand the drug action, therapy, design, development and evaluation Pharmacokinetics is what the Body Does To The Macrolides: pharmacokinetics and pharmacodynamics F. Introduction to Pharmacokinetics • Pharmacokinetics, derived from the Greek words pharmakon (drug) and kinetikos (movement), is used to describe the Biopharmaceutics and Pharmacokinetics Notes Biopharmaceutics and Pharmacokinetics Other Materials Pharmacodynamics Protein therapeutics are usually highly potent compounds with steep dose- effect curves as they are targeted therapies towards a specific, well-described pharmacologic structure or mechanism. STAGE 1: The relationship between the dose and the time course of drug concentrations in biological fluids (pharmacokinetics). It is interesting to note in this context that azithromycin, in contrast to the other macrolides, shows a marked PAE in vivo. ppt / .

Pharmacokinetics represents the absorption, distribution, metabolism, and elimination of drugs from the body. Pharmacokinetics is the study of what the body does to the drug, and Pharmacodynamics is the study of what the drug does to the body. 3. Li Gong and Srijib Goswami contributed equally to the writing of this article. TDM • Clinical pharmacokinetics is also applied to therapeutic drug monitoring (TDM) for very potent drugs, such as those with a narrow therapeutic range, in order to optimize efficacy and to prevent any adverse toxicity. 3 Introduction As previously outlined (1), pharmacology is the scientific study of the action and effects of drugs on living systems and the interaction of drugs with living systems (1-7).
