Pharmacodynamics The study of what the drug does to the body -drug receptor interactions After drugs bind to receptor sites they can... induce or block alterations of shape Agonism the drug mimics the effects of neurotransmitter Antagonism the drug prevents action that would normally be carried out when a drug binds to a receptor inverse agonism binds to the inactive form of a receptor and shifts the equilibrium so that the opposite response to an agonist is produced (from baseline)...
