ketamine hydrochloride injection USP
VETERINARY USE ONLY
KETASET (ketamine hydrochloride) is a rapid acting, nonbarbiturate general anesthetic for cats, chemically designated 2-(o-chlorophenyl)-2-methylaminocyclohexanone hydrochloride. It is supplied as a slightly acid (pH 3.5 - 5.5) solution for intramuscular injection in a concentration containing ketamine (as ketamine hydrochloride) 100 mg per mL and contains 0.10 mg/mL benzethonium chloride as a preservative, and water for injection q.s. as a non-medicinal ingredient.
KETASET (ketamine hydrochloride) is an anesthetic which may be used as a sole agent for restraint and for minor surgical procedures where muscle relaxation is not required in the domestic cat. Additional analgesia should be provided as needed.
Ketaset Dosage And Administration
KETASET (ketamine hydrochloride) is administered by intramuscular injection. Withholding food for at least 6 hours prior to induction of anaesthesia by Ketaset is recommended when preparing for elective surgery.
11-33 mg/kg body weight depending on the degree of restraint or the type of minor surgical procedure that is intended. The following dosages are indicated as a guide but may need to be adjusted depending on the physical condition of the patient and the use of sedatives and premedicants.
Minor surgery and restraint of fractious cats
The use of KETASET (ketamine hydrochloride) is not indicated in kittens under 12 weeks of age as it is not unusual in immature cats for anesthesia to be of shorter duration. Ketamine hydrochloride is contraindicated for procedures in cats requiring complete skeletal muscle relaxation.
For use in cats only. Because the drug is metabolized in the liver and excreted in the urine, although in cats largely unchanged, caution should be exercised in dosing subjects with hepatic or renal impairment. Caution should also be exercised in administering the drug to animals with cardiovascular abnormalities due to its hypertensive effect in cats. Safe use during pregnancy has not been established.
Induction and recovery should occur in quiet and calm surroundings.
Use of premedicants should be followed by a suitable reduction in ketamine dosage.
Eyes remain open and the pupils dilated; they should be protected by bland ophthalmic ointment or covering with a damp gauze swab.
Keep out of reach of children.
At high dosage, respiratory depression may occur. If at any time cyanosis occurs, or if respiration becomes excessively depressed, resuscitative measures should be instituted promptly, e.g., artificial respiration, oxygen administration, etc. May cause salivation in cats; atropine premedication may reduce this effect. Muscular twitching and mild tonic convulsions have occurred in the cat at recommended dose rates; these may subside spontaneously but may be prevented by acepromazine or controlled by use of acepromazine or ultra short acting barbituates in low doses. Use of intramuscular route may be associated with pain. Adverse reactions reported have included emesis, salivation, vocalization, erratic recovery and prolonged recovery, spastic jerking movements, convulsions, muscular tremors, hypertonicity, opisthotonos, dyspnea and cardiac arrest.
KETASET (ketamine hydrochloride) is a rapid acting anesthetic producing an anesthetic state characterized by profound analgesia, normal pharyngeal - laryngeal reflexes and skeletal muscle tone, mild cardiac stimulation and some respiratory depression. The anesthetic state produced by ketamine has been termed “dissociative anesthesia” in that it appears to selectively interrupt association of the brain before producing somesthetic sensory blockade.
Following administration of recommended doses of KETASET (ketamine hydrochloride), blood pressure and heart rate are usually moderately and transiently increased. Respiratory rate, on the other hand, is usually decreased in cats. The pharyngeal reflexes are maintained thus aiding in the maintenance of a patent airway. Although some salivation is occasionally noted, the persistence of the swallowing reflex effectively reduces the hazards of salivation.
Other reflexes, e.g., corneal, pedal, etc., are maintained under KETASET (ketamine hydrochloride) anesthesia, and should not be used as criteria for depth of anesthesia. Moreover, the eyes normally remain open with the pupil dilated, making it prudent to apply a bland ointment if anesthesia is to be prolonged. By single intramuscular injection in cats KETASET (ketamine hydrochloride) has a wide margin of safety.
Following administration of recommended doses of KETASET (ketamine hydrochloride) most cats become ataxic in about 5 minutes, and anesthesia will normally last 30-45 minutes. Recovery is generally smooth and uneventful, especially if animals are not stimulated by sound or handling during the recovery period. At the lower doses complete recovery usually occurs in 4-5 hours but with higher levels of KETASET (ketamine hydrochloride) recovery time is more prolonged and less predictable. With high levels complete recovery may take 24 hours or more in some selected cases, especially if the patient is in poor condition or suffering from nephritis.
StorageStore at a temperature between 15 and 30°C. Protect from light. Once broached, contents should be used within 28 days.
NOTE: Colour of solution may vary from colourless to very slightly yellowish and may darken upon prolonged exposure to light. Do not use if particulate material appears.
KETASET (ketamine hydrochloride) is supplied in multidose 10 mL and 50 mL vials of a solution containing 100 mg/mL.
