Pharmacology is the part of science concerned about the action of medication activity, where a medication can be comprehensively characterized as any man-made, characteristic, or endogenous (from inside body) atom which applies a biochemical or physiological impact on the cell, tissue, organ, or life form (now and again the word pharmacon is utilized as a term to incorporate these endogenous and exogenous bioactive species). All the more particularly, it is the investigation of the collaborations that happen between a living being and synthetic substances that influence ordinary or strange biochemical capacity. On the off chance that substances have therapeutic properties, they are viewed as pharmaceuticals.
