Pharmacodynamics is the branch of pharmacology that deals with the biochemical and physiological effects of the drugs on the body. In simple words it is defined as the branch that studies what a drug does to the body when it is being administered into the system. These drugs affect the body either by mimicking normal biochemical and or physiological processes or inhibiting those vital processes. These drugs perform their function through its mode of actions like stimulating, depressing, blocking, stabilizing, replacing, etc. Also, they may act as direct independent entities that can cause beneficial chemical reactions as free radical scavenging or harmful chemical reactions like cytotoxicity, irritation, etc. The desired activity of a drug is measured by its successful targeting to structures like cell membrane, ligands, receptors, proteins, ion channels, etc. On the other hand the undesirable effects of a drug include increasing the probability of cell mutations, interactions that are additive or multiplicative, or induced physiological damage or chronic conditions. Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature. Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method. Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
