Suxonium - Injection Suxamethonium Chloride (Succinylcholine) - 100mg/2ml 10 Injection(s) / Box Techno Drugs LTD. Introduction: Suxonium belongs to a group of medicines called muscle relaxants. It is used along with general anesthesia or sedatives to provide skeletal muscle relaxation during surgical procedures. It is also used to facilitate emergency airway management in patients in intensive care. Suxonium is administered by a healthcare professional. You should not self-administer this medicine at home. The dose and duration will depend on what you are taking it for and how well it helps your symptoms. The most common side effects of this medicine include If any of these side effects persist or get worse, you should let your doctor... Uses of Suxonium: Skeletal mucle relaxation during surgery Side effects of Suxonium: High blood pressureIncreased heart rateSkin rashSlow heart rate How to use Suxonium: Your doctor or nurse will give you this medicine. Kindly do not self administer. How Suxonium works: Suxonium relaxes the muscles by blocking the impulses from the nerves. Indication: Muscle relaxant Administration: Reconstitution: IV infusion: Suxamethonium Cl 1 g powd for inj or 20 mL of a soln containing 50 mg/mL may be added to 1,000 mL or 500 mL of diluent (e.g. dextrose 5%, dextrose 5% and NaCl 0.9%, NaCl 0.9%, or (1/6) M Na lactate inj) to provide a soln containing 1 mg/mL (0.1%) or 2 mg/mL (0.2%), respectively. Alternatively, suxamethonium Cl 500 mg powd for inj or 10 mL of a soln containing 50 mg/mL may be added to 500 mL or 250 mL of diluents to provide a soln containing 1 mg/mL (0.1%) or 2 mg/mL (0.2%), respectively. Adult Dose: Intravenous Muscle relaxant in general anaesthesia Adult: As suxamethonium Cl: Single dose of 0.3-1.1 mg/kg by inj. Supplementary doses of 50-100% of the initial dose may be given at 5-10 min intervals. For prolonged procedures, 0.1-0.2% soln by infusion at 2.5-4 mg/min, adjusted as necessary. Max (repeated inj or continuous infusion): 500 mg/hr. Intramuscular Muscle relaxant in general anaesthesia Adult: As suxamethonium Cl: 3-4 mg/kg. Max: 150 mg. Child Dose: Intravenous Muscle relaxant in general anaesthesia Child: As suxamethonium Cl: 1 yr Up to 4 mg/kg. Max: 150 mg. Contraindication: Genetic disorders of plasma pseudocholinesterase, personal/family history of malignant hyperthermia, hypersensitivity from previous neuromuscular drug, severe burns, massive trauma, extensive denervation of skeletal muscle, patients with risk of hyperkalaemia, renal impairment, angle closure glaucoma. Mode of Action: Suxamethonium chloride is an ultrashort-acting depolarising type skeletal muscle relaxant. It blocks the neuromuscular junction by binding to the cholinergic receptors and depolarising it. Precaution: Hypersensitivity to any neuromuscular blocker. Patient w/ reduced plasma cholinesterase activity, bone fractures, neuromuscular disorders, cardiac or resp disease, electrolyte imbalance, suspected cardiac glycoside toxicity. Childn. Pregnancy and lactation. Monitoring Parameters Monitor cardiac function and oxygenation during admin; temp, serum K and Ca, assisted ventilator status; neuromuscular function w/ peripheral nerve stimulator. Side Effect: Prolonged resp depression or apnoea, bradycardia, tachycardia, hypotension, HTN, raised intraocular pressure, hyperkalaemia, muscle fasciculation, excessive salivation, jaw rigidity, rash. Potentially Fatal: Anaphylactic and anaphylactoid reactions, acute rhabdomyolysis w/ hyperkalaemia followed by ventricular dysrhythmias and cardiac arrest, malignant hyperthermia. Interaction: Prolonged neuromuscular blocking effects w/ specific anticholinesterase agents (e.g. neostigmine), cytotoxic compd (e.g. cyclophosphamide), antiarrhythmics (e.g. quinidine), aminoglycosides, psychiatric drugs (e.g. chlorpromazine), Mg salts, anaesth agents (e.g. morphine), SSRIs, organophosphate insecticides. Increased susceptibility to the effects of suxamethonium-exacerbated hyperkalaemia w/ digitalis-like drugs.
