Overview
Succinylcholine chloride is a depolarizing neuromuscular blocking agent.
Succinylcholine chloride is a depolarizing neuromuscular blocking agent. The drug binds to the cholinergic receptors of the motor end plate to produce depolarization (which may be observed as fasciculations). Paralysis following succinylcholine administration is progressive, with different muscles exhibiting different sensitivities; paralysis initially involves the levator muscles of the face, followed by the muscles of the glottis, then the intercostals, the diaphragm, and all other skeletal muscles.
Prolonged or repeated administration results in gradual and variable transition from Phase I block to Phase II block, which resembles a nondepolarizing block. The drug possesses histamine-releasing properties, but resultant signs and symptoms are uncommon in normal clinical usage. Succinylcholine causes a slight, transient increase in intraocular pressure immediately after injection and during the fasciculation phase, and the increase may persist after the onset of complete paralysis.
It may also cause slight increases in intracranial pressure immediately after its injection and during the fasciculation phase. Succinylcholine does not have a direct effect on the myocardium, but may cause changes in cardiac rhythm (including cardiac arrest) due to stimulation of autonomic ganglia and muscarinic receptors.
Succinylcholine has a rapid onset and short duration of action. Onset of flaccid paralysis typically occurs less than 1 minute after IV administration and lasts for approximately 4-6 minutes. Following IM administration, the onset of action occurs in about 2-3 minutes.
Succinylcholine is rapidly hydrolyzed by plasma cholinesterase to succinylmonocholine (which possesses clinically insignificant depolarizing muscle relaxant properties); the drug is then metabolized more slowly to succinic acid and choline. Approximately 10% of the drug is excreted in urine.

Today’s intelligence on Quelicin
Indications
The following indications are listed for Quelicin:
- General Anesthesia Adjunct
- Muscle Relaxation
- Skeletal Muscle Relaxation For Endotracheal Intubation
Also known as: Adjunct General Anesthesia, Muscle Flaccidity, Skeletal Muscle Relaxation For Endotracheal Tube Insertion, Skeletal Muscle Relaxation For Intratracheal Intubation, Skeletal Muscle Relaxation For Intubation Of Trachea.
Dosing
Dosage of succinylcholine chloride is expressed in terms of the salt. The dosage must be carefully adjusted according to individual requirements and response. The use of a peripheral nerve stimulator is recommended during continuous IV infusion of the drug to avoid overdose, detect development of Phase II block, follow rate of recovery, and assess the effects of reversing agents.
Succinylcholine chloride usually is administered IV. For patients in whom a suitable vein is not accessible, the drug may be administered by IM injection.
Succinylcholine chloride is supplied in multiple-dose vials and single-dose prefilled syringes containing a 20 mg/mL solution. Unopened vials and prefilled syringes should be stored under refrigeration at 2-8degreesC, but may be kept at room temperature for up to 14 days without significant loss of potency.
Dilution of the 20 mg/mL solution is not required prior to IV or IM injection.
For prolonged procedures, the manufacturer states that succinylcholine chloride may be given by continuous IV infusion or intermittent IV injection. For continuous IV infusion, succinylcholine chloride usually is diluted to a concentration of 1-2 mg/mL with a compatible IV solution such as 5% dextrose injection or 0.9% sodium chloride injection. The 1-mg/mL concentration is usually preferred for optimum rate control. Diluted solutions of succinylcholine chloride may be stored under refrigeration at 2-8degreesC for up to 24 hours. Succinylcholine injections should not be admixed with alkaline (pH exceeding 8.5) solutions (e.g., barbiturates).

Precautions

Safety and effectiveness of succinylcholine have been established in pediatric patients from neonates to adolescents. However, because of the risk of ventricular dysrhythmias, cardiac arrest, and death from hyperkalemic rhabdomyolysis in pediatric patients, use of succinylcholine should be reserved for emergency intubation or instances where immediate securing of the airway is necessary (e.g., laryngospasm, difficult airway, full stomach, or for IM use when a suitable vein is inaccessible).
IV bolus administration of succinylcholine in pediatric patients may result in profound bradycardia or, rarely, asystole; this occurs more commonly among pediatric patients than adult patients.
The effective dose of succinylcholine in pediatric patients may be higher than predicted based on body weight dosing alone.
Available data from published case reports and case series over decades of use have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes with the use of succinylcholine during pregnancy.
Succinylcholine is commonly used during caesarean section to provide muscle relaxation. It is known to cross the placental barrier in an amount that is dependent on the concentration gradient between the maternal and fetal circulation. Apnea and flaccidity can occur in the newborn after repeated high doses of succinylcholine are administered to the mother, or in the presence of atypical plasma cholinesterase in the mother.
Plasma cholinesterase levels are decreased by approximately 24% during pregnancy and for several days postpartum; this can prolong the effect of succinylcholine. If succinylcholine is used during labor and delivery, there is a risk for prolonged apnea.
There are no data regarding the presence of succinylcholine or its metabolite in human or animal milk; the effects on the breast-fed child and effects on milk production are not known.
Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for succinylcholine and any potential adverse effects on the breast-fed infant from the drug or underlying maternal condition.
The manufacturer recommends cautious dose selection, usually starting at the low end of the dosage range, for geriatric patients, reflecting the greater frequency of decreased hepatic, renal, or cardiac function in this patient population.
Clinical studies of succinylcholine did not include sufficient numbers of patients >=65 years of age to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between geriatric and younger patients.
In general, select dosages cautiously in geriatric patients, usually starting at the low end of the dosage range because of the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy in this patient population.
