The general
pharmacology is involves the aspects of sources of drugs, route of administration of drugs, absorption of
drugs and factors affecting them, distribution, bio-transformation and excretion. Pharmacokinetic processes determine the
relationship between drug input (dose, dosage form, frequency, route of administration) and the concentration of drug achieved over time. The major components of
pharmacokinetics are bioavailability, distribution, and clearance. While changes in many of these parameters have been described with aging, the most consistent and marked change in
pharmacokinetics in older adults is the increase in interindividual variability. Bioavailability (F) is the proportion of drug reaching the systemic circulation after administration. Bioavailability depends on the route of administration, the chemical properties of the drug, the absorption of the drug, and the amount of drug that is cleared (first pass loss) before reaching the systemic circulation. This 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.
