Enzyme inhibition is a common mode of drug action.
Drugs can affect ion channels either through specific receptors or by binding to the channel directly.
Drugs produce their action by directly interacting with the solute carrier class of transporter proteins to inhibit the ongoing physiological transport of the metabolite/ion.
Majority of drugs produce action by interaction with specific macromolecules known as receptors.
