Drug interaction is the interaction shown by a substance which affects the activity of the administered drug. The substance which is affecting a drug activity can be another drug when both are administered together. This can also be studied as drug-drug interaction. This interaction can be synergistic or antagonistic in nature thereby causing either an increased or decreased drugs effect. Also there may be a condition in which new a new effect can be produced that is neither produced on its own. However, the interactions may also exist between drug and food called drug-food interactions. There are cases where a particular food should not be taken when a particular drug is under administration as it may result in severe crisis within the system. These accidents usually occur as a result of misuse or due to lack of knowledge about the active ingredients involved in its composition. The study of these interactions therefore seems to be important from the point of practice of medicine. Also, there are cases where an interaction stands from a theoretical point but in actual clinical practice have no important repercussions. High-impact journals are those considered to be highly influential in their respective fields. 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.
