7.2 Drug receptors Receptor is a macromolecule in the membrane or inside the cell that specifically (chemically) bind a ligand (drug). The binding of a drug to receptor depends on types of chemical bounds that can be established between drug and receptor.gonists produce the biological response as a results of receptor âligand interactions therefore agonists posses efficacy. On the contrary antagonists did not provoke any biological activity after binding to its receptor. There are different types of receptors (1): 1. Transmembrane ion-channels receptors 2.
