&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Potency&amp;#039;&amp;#039;&amp;#039; refers to the measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. A highly potent drug (e.g., [[fentanyl]], [[nicotine]], or [[LSD]]) evokes a given response at low concentrations, while a drug of lower potency (e.g., [[ibuprofen]]) calls for higher concentrations to evoke the same response.&lt;br /&gt;
&lt;br /&gt;
== Factors Influencing Potency ==&lt;br /&gt;
Potency is influenced by various factors including the [[affinity]] (the ability of the drug to bind to its receptor), [[efficacy]] (the relationship between receptor occupancy and the ability to initiate a response at the molecular, cellular, tissue or system level) and the [[concentration]] of the drug at the receptor site.&lt;br /&gt;
&lt;br /&gt;
== Potency vs Efficacy ==&lt;br /&gt;
Potency should not be confused with [[efficacy]]. Efficacy refers to the maximum response achievable from a drug, while potency is the amount of drug needed to elicit a desired response. A drug can have high potency but low efficacy and vice versa.&lt;br /&gt;
&lt;br /&gt;
== Measurement of Potency ==&lt;br /&gt;
Potency is usually measured in terms of the concentration or amount of drug required to produce 50% of the drug&amp;#039;s maximal effect (EC50). This is also known as the half maximal effective concentration.&lt;br /&gt;
&lt;br /&gt;
