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.
Drug binding. Many drugs will bind strongly to proteins in the blood or to food. substances in the gut. Binding to plasma proteins will increase the rate of. passive absorption by maintaining the concentration gradient of free drug. For many drugs, the gastrointestinal absorption rate, but not the extent of.
