Drug Efficacy/Intrinsic action: capacity to activate or block a receptor: most outcome a drug can produce whatever the dose
The simulations carried out Together with the product display that when a level of tolerance has made the relation amongst drug dose and drug effect is incredibly different from what is usually assumed.
