Receptor theory in pharmacology

WebbAccording to receptor theory the in vivo potency (i.e., the EC50) and intrinsic activity (i.e., α) are dependent on multiple factors related to the drug (receptor affinity, intrinsic efficacy) and the biological system (receptor density, transducer function relating receptor occupancy to the pharmacological effect) ( Figure 2 ).

WebbCoupled directly to an ion channel. Activation opens the channel, making a cell membrane permeable to specific ions. These channels are known as ‘ligand-gated’ because it is receptor binding that operates them (in contrast to ‘voltage-gated’ channels that respond to changes in membrane potential) (see B in figure).
