In recent years the mimicking of the biological world by chemistry is very productive. So Molecular Pharmacology is a branch of the field of pharmacology which is concerned with the study of pharmacology on a molecular basis. Molecular pharmacologists study the pharmaceuticals and natural compounds used in the treatment of disease, and they also study disease on a molecular basis with the goal of developing pharmacologically active agents which could be used to address disease. In this course we are going to study transport mechanisms in order to understand penetration of drugs across the cell walls membrane similarly; the recent health care area is cardio vascular disorder and stress and many hormonal abnormalities. The pathophysiology and drug designing aspects concerning to CVS disorder is deal in this level of study.
