Trazodone is usually used at a dosage of 150 to 300 mg/day for the treatment of depression. [ 17 ] [ 13 ] Lower doses have also been used to augment other antidepressants or when initiating therapy. [ 17 ] [ 13 ] Higher doses, up to 600 mg/day, have been used in more severe cases of depression (in hospitalized patients, for example). [ 29 ]
In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
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 toxicology, the lethal dose (LD) is an indication of the lethal toxicity of a given substance or type of radiation.Because resistance varies from one individual to another, the "lethal dose" represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die.
This is a list of adverse effects of the antidepressant trazodone, sorted by frequency of occurrence. [1] [2] [3] Very common.
The median toxic dose encompasses the category of toxicity that is greater than half maximum effective concentration (ED 50) but less than the median lethal dose (LD 50). However, for some highly potent toxins (ex. lofentanil , botulinum toxin ) the difference between the ED 50 and TD 50 is so minute that the values assigned to them may be ...
Deaths from single-drug benzodiazepine overdoses occur infrequently, [3] particularly after the point of hospital admission. [4] However, combinations of high doses of benzodiazepines with alcohol , barbiturates , opioids or tricyclic antidepressants are particularly dangerous, and may lead to severe complications such as coma or death.
The fixed-dose procedure (FDP), proposed in 1992 by the British Toxicology Society, is a method to assess a substance's acute oral toxicity. [ 1 ] [ 2 ] In comparison to the older LD 50 test developed in 1927, this procedure produces similar results while using fewer animals and causing less pain and suffering. [ 3 ]
