D-tubocurarine acts by
All non-depolarising blockers (D-Tubocurare) acts as a competitive antagonist of acetylcholine on nicotine (Nm) receptors at myoneural junction .
Inhibiting nicotinic receptors at myoneural junction
Inhibiting nicotinic receptors at autonomic ganglion
Producing depolarizing block
By inhibiting reuptake of acetylcholine
Muscle relaxants
