Drugs that bind to nicotinic cholinergic receptors (RECEPTORS, NICOTINIC) and block the actions of acetylcholine or cholinergic agonists. Nicotinic antagonists block synaptic transmission at autonomic ganglia, the skeletal neuromuscular junction, and at central nervous system nicotinic synapses. (See all compounds classified as Nicotinic Antagonists.)|Drugs that interrupt transmission at the skeletal neuromuscular junction without causing depolarization of the motor end plate. They prevent acetylcholine from triggering muscle contraction and are used as muscle relaxants during electroshock treatments, in convulsive states, and as anesthesia adjuvants. (See all compounds classified as Neuromuscular Nondepolarizing Agents.)

LOW CONCN OF PANCURONIUM BROMIDE (5X10-8 G/ML OR LESS), HAD NO PRESYNAPTIC EFFECT ON MURINE PHRENIC NERVE-DIAPHRAGM PREPN. AT HIGH CONCN (5X10-7 G/ML), PANCURONIUM BROMIDE DEPRESSED QUANTAL RELEASE TO 26% OF CONTROL IN CUT-FIBER PREPN & 40% OF CONTROL IN HIGH-MAGNESIUM PREPN. POSTSYNAPTIC EFFECTS REVEALED DEPRESSION TO 16 & 22% OF CONTROL, RESPECTIVELY, AT A CONCN OF 5X10-7 G/ML. PANCURONIUM BROMIDE HAD NO EFFECT ON DIRECTLY ELICITED ACTION POTENTIALS & ELECTRIC MEMBRANE CONSTANTS. THUS, PRESYNAPTIC AS WELL AS POSTSYNAPTIC EFFECTS OF PANCURONIUM BROMIDE IN PARALYTIC DOSES ARE ESSENTIAL IN CONTRIBUTING TO THE TOTAL EFFICACY OF NEUROMUSCULAR DEPRESSION.|THE PHARMACODYNAMICS OF D-TUBOCURARINE (D-TC), PANCURONIUM BROMIDE, METOCURINE, & GALLAMINE WERE STUDIED IN RAT PHRENIC NERVE-HEMIDIAPHRAGM PREPN WITH VASCULAR PERFUSION AT 25, 31, & 37 °C. D-TC, METOCURINE, & GALLAMINE EACH DEMONSTRATED A NEAR 2-FOLD INCREASE IN ED50 AT 25 °C COMPARED WITH 37 °C. NO SUCH RELATIONSHIP WAS APPARENT WITH PANCURONIUM BROMIDE. SLOPES OF THE DOSE-RESPONSE CURVES WERE NOT INFLUENCED BY TEMP; HOWEVER, THE SLOPES FOR METOCURINE & D-TC WERE LOWER THAN THOSE FOR PANCURONIUM BROMIDE & GALLAMINE. THUS, IN THE RAT, PANCURONIUM BROMIDE RETAINS POTENCY AT HYPOTHERMIA, WHEREAS THE OTHER RELAXANTS DECREASE POTENCY. IN ADDITION, METOCURINE & D-TC EXHIBIT LESS STEEP DOSE-RESPONSE CURVES UNDER THESE EXPTL CONDITIONS.
