Chapter 2 â Drug Affinity and Efficacy In this figure it can be seen that there are different orders of potency for efficacy (maximal response) and affinity (potency); this is a clear indication that the structural differences in the molecules have different effects on efficacy and affinity. Figure 2.10.

- In terms of efficacy, there can be three types of interactions between medications: additive, synergistic, and antagonistic. Additive interaction means the effect of two chemicals is equal to the sum of the effect of the two chemicals taken separately. This is usually due to the two chemicals acting on the body via same or similar mechanism.

Side Effects and Therapeutic Effects Efficacy Vs Effectiveness. A major part of the drug development process is to weed out those compounds whose side effects overwhelm their therapeutic effects. This gets to the fundamental issue of efficacy vs effectiveness. A drug's efficacy is a measure of the ability of the drug to treat whatever condition it is indicated for. It is not a statement about the drug's tolerability or ease of use. Effectiveness is a measure of how well the drug works and encompasses all 3 of these issues. A drug may have very good efficacy but is so unpleasant to take that its actual utility is extremely limited. This would be determined in clinical trials, and the development of such a compound would cease. For those drugs that do make it to market, there usually is a qualitative difference between side effects and therapeutic effects. The side effects of most compounds, psychiatric or otherwise, are transient.

Sensitivity and specificity: Are they measures of validity or reliability ? Specificity and Sensitivity are measures of validity or informedness with respect to the disease rather than accuracy or reliability of the test, and are commonly plotted against each other in ROC (Receiver Operating Characteristics), allowing optimization of the operating point, e.g. by tuning or setting a threshold.

Effectiveness, Efficiency and Efficacy And the last word in the category is Efficacy. Efficacy is getting things done, i.e. meeting targets. Efficacy is the ability to produce a desired amount of the desired effect, or success in achieving a given goal. Contrary to efficiency, the focus of efficacy is the achievement as such, not the resources spent in achieving the desired effect.

SuperNOVA Clinical Stenting Trial Co-Primary Efficacy Endpoints [ Time Frame: 12 months ] The co-primary efficacy endpoints assess vessel primary patency at 12 months post-procedure. The co-primary efficacy analysis (1) will assess vessel primary patency in stented segments intended to be treated with core matrix stents (20 to 150 mm). The co-primary efficacy analysis (2) will assess vessel primary patency in stented segments intended to be treated with the entire stent matrix (20 to 200 mm).
