In common terms, pharmacology is the science of the consequences of drugs on biological systems. In its totality, pharmacology includes knowledge of the sources, chemical properties, biological effects and therapeutic uses of drugs.
It is a science that is fundamental not only to medicine, but also to pharmacy, radiology, nursing, rehabilitation and other.
Pharmacological analysis vary from those that study the effects of chemical agents on subcellular apparatuses, to those that dealing the potential vulnerabilities of pesticides and herbicides, to those that centre on the treatment and prevention of major illnesses with drug therapy.
Pharmacologists also apply molecular modelling and computerized design as drug invention tools to comprehend cell function. New pharmacological areas include the genomic and proteomic methods for therapeutic treatments.
Pharmacology is the study of the therapeutic importance and/or possible toxicity of chemical agents on biological systems. It pursues each aspect of the mechanisms for the chemical actions of both conventional and novel therapeutic agents.
Two essential and interconnected areas are: pharmacodynamics and pharmacokinetics. Pharmacodynamics is the study of the molecular, biochemical, and physiological effects of drugs on cellular systems and their mechanisms of action. Pharmacokinetics deals with the absorption, distribution, and excretion of drugs.
More basically positive, pharmacodynamics is the study of how drugs take effect on the body while pharmacokinetics is the study of how the body works on drugs.
Pharmacodynamic and pharmacokinetic qualities of the action of chemical agents are germane to all related areas of study, as well as toxicology and therapeutics. Toxicology is the study of the difficult or toxic effects of drugs and other chemical agents.
The pharmacological sciences can be further subdivided:
