Sedative
The drugs are given in clinical settings to facilitate medical procedures that would require physical restraint in a conscious patient or otherwise be unfeasible. They are also used to tranquilize dangerous animals. If the animal is in a position where it can't hurt anyone, a slow-acting sedative will be used. If the animal is out-of-control, a fast-acting sedative will be used. Fast-acting sedatives usually take between 3-5 minutes to take effect. Tranquilizer darts are rarely used on humans because there is no way to know which sedative to use and how much to use without performing a pre-anesthetic exam on the patient beforehand. There are only two known cases of a person being intentionally tranquilized, and in both cases the person doing the tranquilizing knew their target's weight and medical history.
