نحوه اثر
Methohexital is a sulfur-free barbiturate anesthetic. After intravenous administration it is rapidly taken up by the brain (within 30 seconds) and rapidly induces sleep. With single doses, the rate of redistribution determines the duration of effect. It provides little analgesia.
دوز معمول بزرگسالان (خلاصه برچسب)
Induction of anesthesia: 1% solution IV at about 1 mL/5 seconds; usual dose 1 to 1.5 mg/kg (range 50 to 120 mg or more, averages about 70 mg); provides anesthesia for 5 to 7 minutes
