A dose is a measured quantity of a medicine, nutrient, or pathogen that is delivered as a unit. The greater the quantity delivered, the larger the dose. Doses are ...
Effective dose (radiation), a measure of cancer/heritable health risk to the whole body from ionizing radiation; Median lethal dose, a measure of the lethal dose of a chemical agent, toxin, radiation, or pathogen; DOSE, an acronym for dopamine, oxytocin, serotonin, and endorphins, the four main chemicals associated with happiness in humans
Dosage typically includes information on the number of doses, intervals between administrations, and the overall treatment period. [3] For example, a dosage might be described as "200 mg twice daily for two weeks," where 200 mg represents the individual dose, twice daily indicates the frequency, and two weeks specifies the duration of treatment.
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
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 ...
The definition was refined in 1950 as "that dose of any ionizing radiation which produces a relevant biological effect equal to that produced by one roentgen of high-voltage x-radiation." [ 19 ] Using data available at the time, the rem was variously evaluated as 83, 93, or 95 erg /gram. [ 20 ]
Dosage forms (also called unit doses) are pharmaceutical drug products presented in a specific form for use. They contain a mixture of active ingredients and inactive components ( excipients ), configured in a particular way (such as a capsule shell) and apportioned into a specific dose .
For medicines the term dose is generally used. In the case of inanimate objects the word dosing is typical. In the case of inanimate objects the word dosing is typical. The term dose titration , referring to stepwise adjustment of doses until a desired level of effect is reached, is common in medicine .
