Pharmacology could be a branch of medication and pharmaceutical sciences that is bothered with the study of drug or medication action,wherever a drug may be broadly speaking or narrowly outlined as any unreal, natural, or endogenous (from among the body) molecule that exerts a organic chemistry or physiological effect on the cell, tissue, organ, or organism (sometimes the word pharmacon is employed as a term to cover these endogenous and exogenous bioactive species). additional specifically, it's the study of the interactions that occur between a living organism and chemicals that have an effect on traditional or abnormal organic chemistry perform. If substances have healthful properties, they're thought-about prescribed drugs. The field encompasses drug composition and properties, synthesis and drug style, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular medical specialty, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. A literature search was conducted using a systematic approach to the search, selection of papers and extraction of data. In total, 2468 records were screened of which 51 fully met the inclusion criteria.
