blockade of postsynaptic receptor
Atropine is generally considered to be a cholinergic muscarinic receptor antagonist.
Atropine is a cholinergic antagonist which blocks the acetylcholine receptor causing increased sympathetic tone increasing the heart rate

It doesn't atropine only acts on muscarinic receptors (it's a competitive antagonist here for ACh), but histamine acts on different receptors (histamine receptors). There is no direct interaction between atropine and histamine receptors
Atropine
There are many. The enzymes that can be affected are choline acetyltransferase (for making acetylcholine), and acetylcholinesterase (for breaking down acetylcholine). The most commonly used enzyme inhibitors affecting the cholinergic system are the acetylcholinesterase inhibitors, such as physostigmine, or neostigmine, etc.
betablockers
Atropine and pralidoxime chloride
Atropine and 2-PAM Chloride are two that can be used. See the Wikipedia article for Nerve Agent
