The effective therapeutic index can be affected by targeting, in which the therapeutic agent is concentrated in its desirable area of effect. For example, in radiation therapy for cancerous tumors, shaping the radiation beam precisely to the profile of a tumor in the "beam's eye view" can increase the delivered dose without increasing toxic ...
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 ...

In addition, the Orange Book contains therapeutic equivalence evaluations (2 character rating codes) for approved multisource prescription drug products (generic drugs). These evaluations have been prepared to serve as public information and advice to state health agencies, prescribers, and pharmacists to promote public education in the area of ...
It is widely used in clinical trials for newer medicines to investigate therapeutic effectiveness and safety. C trough is slightly different from C min, the minimum concentration during the time interval between administration of two doses. [1] [2]
Efficacy is the ability to perform a task to a satisfactory or expected degree. The word comes from the same roots as effectiveness, and it has often been used synonymously, although in pharmacology a distinction is now often made between efficacy and effectiveness.
Effective dose: It is the minimum dose or concentration of a drug that produces a biological response in 50% of a population being studied. Median lethal dose: For either drugs or toxins, it is a toxic unit that measures the minimum dose that causes death (lethal dose) in 50% of cases
As a result, pharmacists had a cleaner picture of the patient's drug therapy and medical conditions. A second publication of R.J Cipolle with L.M Strand in 1998, change the eight categories into seven, grouped in four Pharmacotherapy needs: indication, effectiveness, safety and adherence. [5]
