Talk:Acetylcholinesterase inhibitor

An acetylcholinesterase inhibitor (often abbreviated AChEI) or anti-cholinesterase is a chemical or a drug that inhibits the acetylcholinesterase enzyme from breaking down acetylcholine, thereby increasing both the level and duration of action of the neurotransmitter acetylcholine. Acetylcholinesterase inhibitors are classified as reversible, irreversible, or quasi-irreversible (also called pseudo-irreversible).

Acetylcholinesterase inhibitors

• Banisteriopsis caapi
  • Harmaline
  • Harmine
• Caffeine
• Harmala alkaloids (found in Peganum harmala)
  • Desoxypeganine
  • Harmaline
  • Harmine
  • Harmol
  • Vasicine (possible)
• Piperine (found in Black pepper (Piper nigrum), and Long pepper (Piper longum))

Dangerous interactions

Check (also with independent research) if your AChEIs also inhibits other substances, most AChEIs are also MAOIs and cytochrome P450 inhibitors.

Substances that inhibits MAO enzymes and cytochrome P450 system’s ability to metabolize certain drugs, leading to an overall increase in processing times. When the MAO enzymes and CYP450 system is impacted in this way, it leads to higher levels of certain drugs in your system at one time. This can cause unwanted side effects, and sometimes, an overdose.

AChEIs combined with cholinergic substances can result in a cholinergic crisis.
