|---|
| nondepolarising relaxant | An agent, e.g., tubocurarine, that paralyzes skeletal muscle without depolarisation of the motor endplate, as in phase II block. (05 Mar 2000) |
|---|
| neuromuscular nondepolarising agents | Drugs that interrupt transmission at the skeletal neuromuscular junction without causing depolarisation 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 anaesthesia adjuvants. (12 Dec 1998) |
|---|---|
| nondepolarising block | Skeletal mucle paralysis unaccompanied by changes in polarity of the motor endplate, as occurs following administration of tubocurarine. (05 Mar 2000) |
| nondepolarising neuromuscular blocking agent | A compound that paralyzes skeletal muscle primarily by inhibiting transmission of nerve impulses at the neuromuscular junction rather than by affecting the membrane potention of motor endplate or muscle fibres. (05 Mar 2000) |
| relaxant | 1. Lessening or reducing tension. 2. <pharmacology> An agent that lessens tension. Origin: L. Relaxare = to loosen (18 Nov 1997) |
| relaxant reversal | Use of acetylcholinesterase inhibitors to terminate the action of nondepolarising neuromuscular relaxants. (05 Mar 2000) |
| muscle relaxant | <pharmacology> An agent that specifically AIDS in reducing muscle tension, as those acting at the polysynaptic neurons of motor nerves (for example meprobamate) or at the myoneural junction (curare and related compounds). Origin: L. Relaxare = to loosen (18 Nov 1997) |
| smooth muscle relaxant | An agent, such as an antispasmodic, bronchodilator, or vasodilator, that reduces the tension or tone of smooth (involuntary) muscle. (05 Mar 2000) |
| neuromuscular relaxant | An agent, e.g., curare or succinylcholine, that produces relaxation of striated muscle by interruption of transmission of nervous impulses at the myoneural junction. (05 Mar 2000) |
| depolarising relaxant | <pharmacology, physiology> An agent, e.g., succinylcholine, that induces depolarisation of the motor endplate and so paralyzes skeletal muscle by a phase I block. (05 Mar 2000) |
