Ketalar is a non-barbiturate anesthetic used as an injection indicated for the induction of anesthesia either alone or prior to the administration of other general anesthetic agents. Generic names for Ketalar are ketamine and ketamine hydrochloride. Ketalar is indicated to supplement low-potency agents, such as nitrous oxide. Observed side effects of Ketalar can include low blood pressure, nausea, vomiting.
Ketalar is a non-barbiturate anesthetic. It is formulated as a slightly acid (pH 3.5 - 5.5) sterile solution for intravenous or intramuscular injection in concentrations containing the equivalent of either 10, 50, or 100 mg ketamine base per milliliter and contains not more than 0.1 mg/mL Phemerol (benzethonium chloride) added as a preservative. The 10 mg/mL solution has been made isotonic with sodium chloride. Serious side effects have been reported in as many as 12% of patients; they are psychological states that vary from pleasant dream-like states to hallucinations to delirium all of which may last up to about 24 hours. Patients need to be accompanied until side effects wear off. The drug has the potential to become addictive. The use of Ketalar is not recommended for pregnant patients or for the use of obstetrics and has not been studied in pediatric patients below the age of 16.

Reports suggest that ketamine produces a variety of symptoms including, but not limited to anxiety, dysphoria, disorientation, insomnia, flashbacks, hallucinations, and psychotic episodes. Ketamine dependence and tolerance are possible following prolonged administration. A withdrawal syndrome with psychotic features has been described following discontinuation of long-term ketamine use. Therefore, ketamine should be prescribed and administered with caution.
