What happens if cholinesterase is high?
If these chemicals get into your body, they can affect how you breathe and can cause general muscle weakness. They are called cholinesterase inhibitors. An overdose of these chemicals can be fatal.
What happens when cholinesterase is low?
People who have low levels or defective pseudocholinesterase may experience prolonged effects of the drug, with protracted muscle paralysis and apnea following anesthesia. In addition, those who are homozygous for genetic variants may be at greater risk of adverse effects than those who are heterozygous.
What are the side effects of cholinesterase?
The most common adverse effects of cholinesterase inhibitors include nausea, diarrhea, vomiting, decreased appetite, dyspepsia, anorexia, muscle cramps, fatigue, insomnia, dizziness, headache, and asthenia. Taking these medications with food, preferably a full meal, can mitigate these gastrointestinal effects.

The most common naturally occurring cholinesterase inhibitors, the SGAs, are found in plants of Solanaceae such as potato, eggplant, and tomato. The main SGAs in potatoes are α-solanine and α-chaconine, both triglycosides of solanidine, a steroidal alkaloid derived from cholesterol (Figure 2).
What causes cholinesterase deficiency?
You can develop pseudocholinesterase deficiency as a result of conditions that cause you to make less of the pseudocholinesterase enzyme. These conditions include chronic infections, kidney or liver disease, malnutrition, severe burns, cancer, or pregnancy. Certain medications also can reduce production of the enzyme.

What is cholinesterase poisoning?
Cholinesterase inhibitor toxicity is due to a decrease in the ability of cholinesterase to breakdown acetylcholine which results in excessively high acetylcholine levels. Cholinesterase inhibitors fall into two classes, organophosphorus compounds, and carbamates.

How does acetylcholinesterase work?
Acetylcholinesterase is involved in transmission of nerve impulses by breaking down acetylcholine, a chemical that helps to transmit signals across nerve endings. A decrease in the activity of the enzyme acetylcholinesterase results in excess acetylcholine at nerve endings. This can lead to overstimulation of nerves within body tissues and organs. Pseudochlinesterase is involved in processing and metabolizing drugs.
