Neuromuscular blocking agents relax skeletal muscle to produce flaccid paralysis; the first mus-cles to be affected are the levator muscle of the eyelids and the muscles of mastication.

Mechanical ventilation is necessary when the drug affects the intercostal muscles and the diaphragm, interfering with respiration.
