Pharmaceutical medications are an important piece of patient consideration all through the world. For specialists to sufficiently think about their patients, sedate security must be observed and revealed from beginning testing to ordinary use. This is the universe of pharmacovigilance. The World Health Organization characterizes pharmacovigilance (PV) as "the science and exercises identifying with the discovery, evaluation, comprehension and avoidance of antagonistic impacts or some other medication related issue. "Pharmacovigilance starts with clinical preliminaries that give information on the advantages and dangers of a medication. The point of pharmacovigilance in clinical exploration is to decide whether the advantages exceed the dangers; on the off chance that they do, tranquilize producers find a way to pick up endorsement to advertise the new medication. The information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
