WHAT IS SIMULATION? Computer simulation is the discipline of designing a model of an actual or theoretical physical system, executing the model on a digital computer, and analyzing the execution output.
Efficacy is defined as the maximum effect a drug can produce, regardless of the dose. Potency is related to the amount of drug needed to produce a given effect; it is often quantified by the ED50 or EC50, which are respectively the drug dose or concentration that causes 50% of the maximum effect. Affinity is defined as a drug's ability to bind to a receptor.
Potency versus Efficacy. The term commonly used is efficacy-in other words, if two drugs occupy the same number of receptors on a tissue, and one drug elicits a greater biological response than the other drug (by its action on the receptor) then that drug has greater efficacy.otency versus Efficacy.
