premise: Pharmacology deals with the elucidation of cellular and organismal function in relation to chemicals.
hypothesis: Pharmacology . More specifically , it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function . The field encompasses drug composition and properties , synthesis and drug design , molecular and cellular mechanisms , organ/systems mechanisms , signal transduction/cellular communication , molecular diagnostics , interactions , toxicology , chemical biology , therapy , and medical applications and antipathogenic capabilities . In broad terms , pharmacodynamics discusses the chemicals with biological receptors , and pharmacokinetics discusses the absorption , distribution , metabolism , and excretion ( ADME ) of chemicals from the biological systems . Pharmacology , a biomedical science , deals with the research , discovery , and characterization of chemicals which show biological effects and the elucidation of cellular and organismal function in relation to these chemicals .
