Special Precautions
Not be injected from the same syringe w/ barbiturates. Verbal, tactile & visual stimuli should be kept to a minimum during recovery in an attempt to reduce the risk of emergence reactions. Emergence delirium phenomena may occur during the recovery period. Avoid mechanical stimulation of the pharynx unless muscle relaxant is co-administered. Aspiration of contrast medium. Monitor cardiac function for patients w/ HTN or cardiac decompensation. Patients w/ pre-anesth elevated CSF pressure. Resp depression. Mechanical support of respiration is preferred for analeptics. Rapid administration may result in transient resp depression or apnea. Chronic alcoholism & acute alcohol intoxication. Pregnancy & lactation.
Adverse Reactions
Hypotension, bradycardia, arrhythmia; resp depression or apnea, laryngospasm & other airway obstruction; diplopia, nystagmus, slight elevation of IOP; delirium w/ or w/o psychomotor activity (confusion & irrational behavior); tonic & clonic movements resembling seizures; anorexia, nausea, vomiting; local pain & exanthema at inj site, transient erythema or morbilliform rash, increased salivation leading to resp difficulties.
Drug Interactions
May potentiate neuromuscular blocking effects of atacurium & tubocurarine including resp depression w/ apnoea. May lengthen the elimination t½ & delay recovery from anesth w/ halogenated anesth which can lead to bradycardia, hypotension or decreased cardiac output. Potentiation of CNS depression &/or increased risk of developing resp depression w/ CNS depressants eg, ethanol, phenothiazines, sedating H1 blockers or skeletal muscle relaxants. May antagonize hypnotic effect of thiopental. Increased risk of developing HTN & tachycardia w/ thyroid hormones. Increased risk of developing hypotension w/ antihypertensive. Significant reduction in seizure threshold w/ theophylline. Increased plasma conc w/ CYP3A4 inhibitors. Decreased plasma conc w/ CYP3A4 inducers.
