Pharmacology is the science of drug action on biological systems. It embraces knowledge of the sources, chemical properties, biological effects and therapeutic uses of drugs. It is a science that is basic not only to medicine, but also to pharmacy, nursing, dentistry and veterinary medicine. Pharmacological studies range from those that determine the effects of chemical agents upon subcellular mechanisms, to those that deal with the potential hazards of pesticides and herbicides, to those that focus on the treatment and prevention of major diseases by drug therapy. Pharmacologists are also involved in molecular modeling of drugs, and the use of drugs as tools to dissect aspects of cell function.
Pharmacology is an
essential subject to understand the action of drugs. I have made an
attempt to provide you some materials of pharmacology, drug classifications and
some other ebooks

Bioassay is an estimation or determination of concentration or potency of physical, chemical or biological agents by means of measuring and comparing the magnitude of the response of the test with that of standard over a suitable biological system under standard set of conditions. Bioassay is a successful tool in estimation and discovery of biologically active substances and important application in sensitivity and specificity of pharmacological applications. Chemical method is very complex method which requires high chemical dosage and chemical composition shows the pharmacological actions against the drug.
It is a study of structures all the organs of the human body. Macroscopic anatomy describes structures, organs, muscles, bones etc. which are visible to the naked eye, that is macroscopic. In order to establish a certain order they are divided topographically and systematically.
Microscopic human anatomy is the „study of tissues“, that is histology. It may be further separated into cytology, the pure study of cells. In contrast to macroscopic anatomy you require – as the name suggests - an optical magnification in order to evaluate microscopic (e.g. cellular) structures.
Hospital pharmacies are pharmacies usually found within the premises of a hospital. Hospital pharmacies usually stock a larger range of medications, including more specialized and investigational medications. Hospital pharmacies typically provide medications for the hospitalized patients only, and are not retail establishments and therefore typically do not provide prescription service to the public.
Health education is a basic process of giving information about health and to motivate the people in a systematic manner, to follow the methodology for the protection and promotion of health of individuals, their families and communities
