Midazolam, sold under the brand name Versed among others, is a benzodiazepine medication used for anesthesia, premedication before surgical anesthesia, and procedural sedation, and to treat severe agitation. [12] It induces sleepiness, decreases anxiety, and causes anterograde amnesia. [12]
At the typical dose, anesthesia is induced for the duration of about 5–10 minutes, though the half-life of drug metabolism is about 75 minutes, because etomidate is redistributed from the plasma to other tissues. Onset of action: 30–60 seconds; Peak effect: 1 minute; Duration: 3–5 minutes; terminated by redistribution
Onset of action is the duration of time it takes for a drug's effects to come to prominence upon administration. With oral administration , it typically ranges anywhere from 20 minutes to over an hour, depending on the drug in question.
In recreational psychoactive drug spaces, duration refers to the length of time over which the subjective effects of a psychoactive substance manifest themselves. Duration can be broken down into 6 parts: (1) total duration (2) onset (3) come up (4) peak (5) offset and (6) after effects.
Among all benzodiazepine agents, midazolam (Versed) is the most frequently used medication for palliative sedation for its rapid onset and short duration of action. The main indications for midazolam in palliative sedation are to control delirium and alleviate breathing difficulties so as to minimize distress and prevent exacerbation of these ...
The duration of estradiol esters in oil solution by intramuscular injection is dose-dependent. [282] With estradiol valerate, it is reported that a dose of 5 mg has a duration of 7 to 8 days, [274] 10 mg a duration of 10 to 14 days, [265] [282] 40 mg a duration of 2 to 3 weeks, and 100 mg a duration of 3 to 4 weeks. [282]
The area under the effect curve (AUEC) is an integral of the effect of a drug over time, estimated as a previously-established function of concentration. It was proposed to be used instead of AUC in animal-to-human dose translation, as computer simulation shows that it could cope better with half-life and dosing schedule variations than AUC.
[3] [23] In these individuals, the onset of action of phenibut has been reported to be 2 to 4 hours orally and 20 to 30 minutes rectally, the peak effects are described as occurring 4 to 6 hours following oral ingestion, and the total duration for the oral route has been reported to be 15 to 24 hours (or about 3 to 5 terminal half-lives).
