Calypsol - Injection Ketamine - 500mg 1 Injection(s) / Injection Unknown Introduction: Calypsol is a general anesthetic. It is used in major surgical procedures. It allows the procedures to be carried out without pain and distress. This injection is used in a hospital setting only. Calypsol is used in general anesthesia. It causes loss of consciousness which is reversible. It is administered under the supervision of a healthcare professional. The most common side effects include rash, nausea or vomiting. Inform your doctor if you are pregnant or are suffering from severe heart disease or had a stroke recently or suffered serious head or brain injury. It is safe to use in breastfeeding... Uses of Calypsol: General Anaesthesia Side effects of Calypsol: RashErythema (skin redness)VomitingNauseaAgitationNightmareAbnormal behaviorDouble visionHallucinationIncreased respiratory rateHigh blood pressureConfusionNystagmus (involuntary eye movement)Muscle coordination impairedTonic-clonic seizuresTachycardia How to use Calypsol: Your doctor or nurse will give you this medicine. Kindly do not self administer. How Calypsol works: Calypsol is a general anaesthetic. It works by causing reversible loss of consciousness. This allows surgical procedures to be carried out without pain and distress. Indication: Induction of anesthesia. Administration: Reconstitution: 50 mg/mL and 100 mg/mL vials may be further diluted in 5% dextrose or 0.9% NaCl to prepare a maintenance infusion containing 1 mg/mL (or 2 mg/mL in patients w/ fluid restrictions). Adult Dose: Intravenous Induction of anaesthesia Adult: 1-4.5 mg/kg via slow IV inj over 60 sec. A dose of 2 mg/kg produces surgical anaesthesia w/in 30 sec after inj lasting for 5-10 min. Increments of half to the full induction dose may be repeated as needed for maintenance of anesth. Alternatively, a total induction dose of 0.5-2 mg/kg via infusion, given at an appropriate rate, and maintained at a rate of 10-45 mcg/kg/min, adjusted according to response. Intramuscular Induction of anaesthesia Adult: 6.5-13 mg/kg. A dose of 10 mg/kg produces surgical anaesthesia w/in 3-4 min after inj lasting for 12-25 min. Increments... Contraindication: Hypertension, history of cerebrovascular accident. Eye injury, raised ocular and intracranial pressure. Psychotic disorders. Mode of Action: Ketamine is a noncompetitive N-methyl-D-aspartate receptor antagonist that blocks glutamate. It has a direct action on the cortex and limbic system. It produces a cataleptic-like state wherein the patient is withdrawn from the surrounding environment. Precaution: Minimise verbal and tactile stimulation during recovery period. Chronic alcoholic and alcohol-intoxicated patients. Preanaesthetic elevated CSF pressure. Dependence and tolerance may develop. May impair ability to drive or operate machinery. Monitor cardiac function in patients with hypertension or cardiac decompensation. Pregnancy and lactation. Side Effect: >10% Emergence rxns (Emergence reactions e.g. vivid dreams, hallucinations, confusion, irrational behaviour) HTN,Increased cardiac output,Increased ICP,Tachycardia,Tonic-clonic movements,Visual hallucinations,Vivid dreams 1-10% Bradycardia,Diplopia,Hypotension,Increased IOP,Injection-site pain,Nystagmus <1% Anaphylaxis,Cardiac arrhythmia,Depressed cough reflex,Fasciculations,Hypersalivation,Increased IOP,Increased metabolic rate,Hypertonia,Laryngospasm,Respiratory depression or apnea with large doses or rapid infusions Interaction: Prolonged recovery time w/ barbiturates or narcotics. May potentiate neuromuscular blocking effects of atracurium and tubocurarine including resp depression w/ apnoea. May increase risk of bradycardia, hypotension or decreased cardiac output w/ halogenated anaesth. May potentiate CNS depression and risk of resp depression w/ CNS depressants (e.g. phenothiazines, sedating H1-blockers, skeletal muscle relaxants). May antagonise hypnotic effect of thiopental. May increase risk of HTN w/ thyroid hormones. May increase risk of hypotension w/ antihypertensive agents. Reduction in seizure threshold resulting in unpredictable extensor-type seizures when given concurrently w/ theophylline.
