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, Efficacy, and Effectiveness. A drugâs effects can be evaluated in terms of potency, efficacy, or effectiveness. Potency (strength) refers to the amount of drug (usually expressed in milligrams) needed to produce an effect, such as relief of pain or reduction of blood pressure.fficacy is a drug's capacity to produce an effect (such as lowering blood pressure). For example, the diuretic furosemide eliminates much more salt and water through urine than does the diuretic hydrochlorothiazide.
