Soman reduced blood and brain cholinesterase (ChE) activity to less than 15% and increased cerebral acetylcholine (ACh) levels to 137.4% of control. When pyridostigmine (P) was used as a prophylatic adjunct, it reduced blood ChE activity to 31.6% of control, failed to significantly alter ...
pyridostigmineincreases acetylcholine levels in the neuromuscular junctions, with a consequent increase in motor tone.Pyridostigminehas also been used to protect against exposure toanticholinesterasenerve agents (e.g., sarin). Because pyridostigmine has a much shorter duration of inhibition and does not ...
Since it is a quaternary amine, it is poorly absorbed in the gut and does not cross the blood–brain barrier, except possibly in stressful conditions. Pyridostigmine inhibits acetylcholinesterase in the synaptic cleft, thus slowing down the hydrolysis of acetylcholine. It is a quaternary carbamate ...

Acetylcholine (ACh) is an important neurotransmitter in the autonomic nervous system (ANS) and the primary excitatory neurotransmitter in the enteric nervous system (ENS), which controls digestive functions. Acute exposure to PB increases the availability of ACh and the resulting contact time with ...

Inhibits metabolism of acetylcholine (ACh) by cholinesterase (AChE); thereby, permits freer transmission of nerve impulses across the neuromuscular junction Pyridostigmine is an analog of neostigmine, but differs from it in certain clinically significant respects (eg, longer duration of action, fewer GI...
Muscarinic acetylcholine receptor (m2 mAChR) ligand binding with [(3)H]AFDX-384 in cortex and brain stem showed significant increases (approximately 120-130% of control) following coexposure to PB and sarin at higher doses. To evaluate the potential of PB for augmentation or inhibition of the...
down the hydrolysis of acetylcholine. It is a quaternary carbamate inhibitor of cholinesterase that does not cross the blood–brain barrier which carbamylates about 30% of peripheral cholinesterase enzyme. The carbamylated enzyme eventually regenerates by natural hydrolysis and excess ACh levels revert ...
