The neuromuscular blocking and circulatory effects of a recently synthesized relatively short acting nondepolarizing muscle relaxant, Duador, have been investigated in anaesthetized patients. Duador appears to be a potent muscle relaxant with intermediate duration of action. It had no cumulative effects even after as many as five maintenance doses. Doses of 0.4 mg/kg provided ideal intubating conditions in 2 min, though maximal blockade only developed in about 6 min. Duador was easily antagonized by edrophonium and no signs of recurarisation have been observed. The initial dose of Duador caused a mean 28% increase in heart rate. The increase in heart rate was inversely proportional to the control rate. Repeat doses did not cause further elevation in frequency. Duador had no effect on mean blood pressure.

UI MeSH Term Description Entries
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009435 Synaptic Transmission The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES. Neural Transmission,Neurotransmission,Transmission, Neural,Transmission, Synaptic
D009469 Neuromuscular Junction The synapse between a neuron and a muscle. Myoneural Junction,Nerve-Muscle Preparation,Junction, Myoneural,Junction, Neuromuscular,Junctions, Myoneural,Junctions, Neuromuscular,Myoneural Junctions,Nerve Muscle Preparation,Nerve-Muscle Preparations,Neuromuscular Junctions,Preparation, Nerve-Muscle,Preparations, Nerve-Muscle
D001794 Blood Pressure PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS. Systolic Pressure,Diastolic Pressure,Pulse Pressure,Pressure, Blood,Pressure, Diastolic,Pressure, Pulse,Pressure, Systolic,Pressures, Systolic
D003473 Neuromuscular Nondepolarizing Agents 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.

D004491 Edrophonium A rapid-onset, short-acting cholinesterase inhibitor used in cardiac arrhythmias and in the diagnosis of myasthenia gravis. It has also been used as an antidote to curare principles. Edrophonium Chloride,Edrophonium Bromide,Edroponium,Tensilon,Bromide, Edrophonium,Chloride, Edrophonium
D006339 Heart Rate The number of times the HEART VENTRICLES contract per unit of time, usually per minute.
