D–tubocurarine acts by –
All non-depolarizing blockers (D-tubocurarine) act as competitive antagonist of acetylcholine on nicotinic (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
