What constitutes a therapeutic effect versus a side effect is a matter of both the nature of the situation and the goals of treatment. No inherent difference separates therapeutic and undesired side effects; both responses are behavioral/physiologic changes that occur as a response to the treatment strategy or agent. [2]
The therapeutic window is the amount of a medication between the amount that gives an effect (effective dose) and the amount that gives more adverse effects than desired effects. For instance, medication with a small pharmaceutical window must be administered with care and control, e.g. by frequently measuring blood concentration of the drug ...
In medicine, efficacy is the capacity for beneficial change (or therapeutic effect) of a given intervention (for example a drug, medical device, surgical procedure, or a public health intervention). [8] Establishment of the efficacy of an intervention is often done relative to other available interventions, with which it will be compared. [9]
In this case, both the therapeutic and toxic targets are the same. To avoid toxicity during treatment, many times the drug needs to be changed to target a different aspect of the illness or symptoms. Statins are an example of a drug class that can have toxic effects at the therapeutic target (HMG CoA reductase). [1]
The inverse benefit law describes the relationship between a drugs therapeutic benefits and its marketing. When designing drugs, the placebo effect must be considered to assess the drug's true therapeutic value. Drug development uses techniques from medicinal chemistry to chemically design drugs. This overlaps with the biological approach of ...
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
An Israeli student who attended graduate school at Harvard dealt with hostility due to his religious identity and found himself at odds with a professor who compared the idea of the Jewish state ...
Because the breast cancer medication trastuzumab is known to target protein HER2, for example, tumors can be screened for the presence of this molecule to determine whether or not the patient will benefit from trastuzumab therapy. [6] [7] It can enable better dosing because the drug's effects on the target pathway can be monitored in the patient.
