Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
The therapeutic index (TI; also referred to as therapeutic ratio) is a quantitative measurement of the relative safety of a drug with regard to risk of overdose.It is a comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect. [1]
The ED50 is commonly used as a measure of the reasonable expectancy of a drug effect, but does not necessarily represent the dose that a clinician might use. This depends on the need for the effect, and also the toxicity. The toxicity and even the lethality of a drug can be quantified by the TD 50 and LD 50 respectively. Ideally, the effective ...
The United States Environmental Protection Agency defines NOAEL as 'an exposure level at which there are no statistically or biologically significant increases in the frequency or severity of adverse effects between the exposed population and its appropriate control; some effects may be produced at this level, but they are not considered as adverse, or as precursors to adverse effects.

It is a combination of ezetimibe (known as Zetia in the United States) and the statin drug simvastatin (known as Zocor in the US). Ezetimibe reduces blood cholesterol by acting at the brush border of the small intestine and inhibiting the absorption of cholesterol, leading to a decrease in the delivery of intestinal cholesterol to the liver.
This is not to be confused with dose regimen, which is a type of drug therapy in which the dose [mg] of a drug is given at a regular dosing interval on a repetitive basis. Continuing the maintenance dose for about 4 to 5 half-lives (t 1/2 ) of the drug will approximate the steady state level. [ 1 ]
