What terms are used to describe the concepts of therapeutic effect?

The terms used to describe the concepts of therapeutic effect are "toxicity" and "efficacy." Efficacy refers to the ability of a treatment to produce a desired therapeutic effect under ideal conditions. In other words, it measures how well a drug performs its intended action in controlled scenarios, showing its potential benefits. Toxicity, on the other hand, describes the harmful effects that a drug can produce when its concentration exceeds the therapeutic range, leading to adverse effects. Understanding both efficacy and toxicity is essential in evaluating a drug's overall therapeutic effect, as a balance between the two is necessary to achieve optimal patient outcomes.

Other concepts listed, such as absorption and metabolism, pertain to pharmacokinetics rather than directly describing the therapeutic effect. Potency and dilution relate to the strength and concentration of the drug, but do not provide a direct measure of its therapeutic outcomes. In summary, toxicity and efficacy are pivotal in assessing the safety and effectiveness of therapeutic interventions.
