Sedative
Definition:
(a.) Tending to calm, moderate, or tranquilize
(a.) allaying irritability and irritation; assuaging pain.
(n.) A remedy which allays irritability and irritation, and irritative activity or pain.
Example Sentences:
(1) The effects of sessions, individual characteristics, group behavior, sedative medications, and pharmacological anticipation, on simple visual and auditory reaction time were evaluated with a randomized block design.
(2) Open field behaviors and isolation-induced aggression were reduced by anxiolytics, at doses which may be within the sedative-hypnotic range.
(3) However, the degree of sedation caused by diphenhydramine was significantly greater than that caused by cimetidine (P = .0001).
(4) Although lorazepam and haloperidol produced an equivalent mean decrease in aggression, significantly more subjects who received lorazepam had a greater decrease in aggression ratings than haloperidol recipients; this effect was independent of sedation.
(5) Adverse outcomes were reported more frequently by consultant physicians, by those who 'titrated' the intravenous sedative, and by those who used an additional intravenous agent, but were reported equally frequently by endoscopists using midazolam and endoscopists using diazepam.
(6) Alterations in mean systolic blood pressure appeared to be modest, consisting of a 10 percent decrease from the control level, related to sedation, and a 10 percent rise from baseline during the procedure, associated with a concomitant mild tachycardia.
(7) We have evaluated the action of hypnotics on the sleep-wakefulness cycle in freely implanted rats during their maximally active period because it is easier to estimate the duration of the sedative effect.
