Non-competitive/irreversible antagonism: If an antagonist binds towards the receptor and precludes agonist activation of that receptor by its occupancy, then no volume of agonist current within the receptor compartment can prevail over this antagonism is termed non-aggressive.
Fig. two demonstrates how the adaptive regulator learns to make a compensatory response any time a drug is administered regularly. It little by little learns to readjust the process parameters during the disturbance
