Classifications: autonomic nervous system agent; depolarizing skeletal muscle relaxant
Pregnancy Category: C
20 mg/mL, 50 mg/mL, 100 mg/mL injection; 500 mg, 1 g vials
Synthetic, ultrashort-acting depolarizing neuromuscular blocking agent with high affinity for acetylcholine (ACh) receptor sites.
Initial transient contractions and fasciculations are followed by sustained flaccid skeletal muscle paralysis produced by state of accommodation that develops in adjacent excitable muscle membranes. Rapidly hydrolyzed by plasma pseudocholinesterase.
To produce skeletal muscle relaxation as adjunct to anesthesia; to facilitate intubation and endoscopy, to increase pulmonary compliance in assisted or controlled respiration, and to reduce intensity of muscle contractions in pharmacologically induced or electroshock convulsions.
Hypersensitivity to succinylcholine; family history of malignant hyperthermia.
During delivery by cesarean section; lactation; kidney, liver, pulmonary, metabolic, or cardiovascular disorders; dehydration, electrolyte imbalance, patients taking digitalis, severe burns or trauma, fractures, spinal cord injuries, degenerative or dystrophic neuromuscular diseases, low plasma pseudocholinesterase levels (recessive genetic trait, but often associated with severe liver disease, severe anemia, dehydration, marked changes in body temperature, exposure to neurotoxic insecticides, certain drugs); collagen diseases, porphyria, intraocular surgery, glaucoma; pregnancy (category C).
