Keita Injection

KETALAR (ketamine hydrochloride) injection is indicated: as the sole anesthetic agent for diagnostic and surgical procedures that do not require skeletal muscle relaxation. for the induction of anesthesia prior to the administration of other general anesthetic agents. as a supplement to other anesthetic agents. KETALAR is a general anesthetic indicated: as the sole anesthetic agent for diagnostic and surgical procedures that do not require skeletal muscle relaxation ( 1 ) for the induction of anesthesia prior to the administration of other general anesthetic agents ( 1 ) as a supplement to other anesthetic agents ( 1 ).

• See Full Prescribing Information for important dosage and administration instructions
• Induction of anesthesia: -- Intravenous route : Initially, 1 to 4.5 mg/kg administered slowly (over a period of 60 seconds)
• Alternatively, administer a dose of 1 to 2 mg/kg at a rate of 0.5 mg/kg/min. -- Intramuscular route : Initially, 6.5 to 13 mg/kg
• Maintenance of anesthesia: Increments of one-half to the full induction dose may be repeated as needed
• Adjust the dose according to the patient's anesthetic needs and whether an additional anesthetic agent is employed
• Supplement to other anesthetic agents : The regimen of a reduced dose of KETALAR supplemented with diazepam can be used to produce balanced anesthesia by combination with other agents
• Important Dosage and Administration Information KETALAR should be administered by or under the direction of physicians experienced in the administration of general anesthetics, maintenance of a patent airway, and oxygenation and ventilation
• Continuously monitor vital signs in patients receiving KETALAR
• Emergency airway equipment must be immediately available
• KETALAR is a clear, colorless sterile solution
• Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit
• Discard if product is discolored or contains particulate matter
• Do not administer the 100 mg/mL concentration of KETALAR intravenously without proper dilution [see Dosage and Administration ] . …

KETALAR injection is a clear, colorless, sterile solution available in multiple-dose vials containing either 10 mg ketamine base (equivalent to 11.53 mg ketamine hydrochloride), 50 mg ketamine base (equivalent to 57.67 mg ketamine hydrochloride) or 100 mg ketamine base (equivalent to 115.33 mg ketamine hydrochloride). …

• Safety and effectiveness
• In pediatric patients below the age of 16 have not been established
• Published juvenile animal studies demonstrate that the administration of anesthetic and sedation drugs, such as KETALAR, that either block NMDA receptors or potentiate the activity of GABA during the period of rapid brain growth or synaptogenesis, results in widespread neuronal and oligodendrocyte cell loss in the developing brain and alterations in synaptic morphology and neurogenesis. …

Clinical studies of ketamine hydrochloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. …

• Studies conducted in young animals and children suggest repeated or prolonged use of general anesthetic or sedation drugs in children younger than 3 years may have negative effects on their developing brains
• Discuss with parents and caregivers the benefits, risks, and timing and duration of surgery or procedures requiring anesthetic and sedation drugs [see Warnings and Precautions ]
• Due to the residual anesthetic effects and the potential for drowsiness, advise patients not to drive an automobile, operate hazardous machinery, or engage in hazardous activities within 24 hours of receiving KETALAR

• KETALAR is contraindicated in patients for whom a significant elevation of blood pressure would constitute a serious hazard [see Warnings and Precautions ]
• KETALAR is contraindicated in patients with known hypersensitivity to ketamine or to any excipient [see Adverse Reactions ]
• In patients for whom a significant elevation of blood pressure would be a serious hazard
• Known hypersensitivity to ketamine or to any excipient

Theophylline or Aminophylline : Do not co-administer with KETALAR as concomitant use may lower the seizure threshold ( 7.1 ). Sympathomimetics and Vasopressin : Closely monitor vital signs when co-administered with KETALAR. Consider dose adjustment individualized to the patient’s clinical situation ( 7.2 ). Benzodiazepines, Opioid Analgesics, or other CNS Depressants : Concomitant use may result in profound sedation, respiratory depression, coma, or death. Concomitant use of opioid analgesics may prolong recovery time. ( 7.3 ). 7.1 Theophylline or Aminophylline Concomitant administration of KETALAR and theophylline or aminophylline may lower the seizure threshold. …

Hemodynamic Instability: Monitor vital signs and cardiac function during KETALAR administration. ( 5.1 ) Emergence Reactions: Postoperative confusional states may occur during the recovery period. Reduce by minimizing verbal, tactile, and visual stimulation of the patient. ( 5.2 ) Risk of Respiratory Depression: May occur with overdosage or too rapid a rate of administration. Maintain adequate oxygenation and ventilation. ( 5.3 ) Risks of KETALAR alone for Procedures of the Pharynx, Larynx, or Bronchial Tree : Pharyngeal and laryngeal reflexes are not suppressed with KETALAR when it is used alone. …

The following clinically significant adverse reactions are described elsewhere in the labeling: Hemodynamic Instability [see Warnings and Precautions ( 5.1 )] Emergence Reactions [see Warnings and Precautions ( 5.2 )] Respiratory Depression [see Warnings and Precautions ( 5.3 )] Pediatric Neurotoxicity [see Warnings and Precautions ( 5.5 )] Drug-Induced Liver Injury [see Warnings and Precautions ( 5.6 )] The following adverse reactions associated with the use of KETALAR were identified in clinical studies or postmarketing reports. …

8.1 Pregnancy Risk Summary Available data on the use of ketamine in pregnant women mostly describe its use at the time of cesarean section and have not identified a drug-associated risk of adverse maternal or fetal outcomes. The data are limited by retrospective collection, small sample sizes, and a lack of long-term follow-up. …

Changes in heart rate and blood pressure, respiratory depression, and apnea may occur with overdosage or by a rapid rate of administration of KETALAR. Monitor patients for clinically relevant changes in heart rate and blood pressure. Assisted ventilation, including mechanical ventilation, may be required. In cases of unintentional overdose of KETALAR (up to ten times the usual dose), patients had a prolonged but complete recovery.

9.1 Controlled Substance KETALAR contains ketamine, a Schedule III controlled substance under the Controlled Substance Act. 9.2 Abuse Individuals with a history of drug abuse or dependence may be at greater risk for abuse and misuse of KETALAR. Abuse is the intentional, non-therapeutic use of a drug, even once, for its psychological or physiological effects. …

Tómala en cuanto te acuerdes, salvo que falte poco para la siguiente. En ese caso, sáltate la olvidada. Nunca tomes dos dosis a la vez para compensar. Revisa tu prospecto, porque algunos medicamentos son distintos.
