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