Pharmacokinetics is the branch of pharmacology that deals with the determination of the fate of the drug when administered into a living system till the point it gets completely eliminated from the body. In simple words it is defined as the branch that studies what the body does to a drug when it is being administered into the system. It describes the aspects on how the body affects a particular drug through the mechanisms of absorption and distribution; as well as the effects and routes of excretion of drug metabolites. It also highlights the undergone chemical changes of the drug while in the body due to the action of metabolizing enzymes. The pharmacokinetic properties of the drug are affected by elements like dose of drug and site of its administration that may affect the drug absorption rates. The branch of pharmacokinetics is often studied in conjunction with pharmacodynamics to study an overall drugs pharmacological effects on the body. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
