Y51: Drugs primarily affecting the autonomic nervous system

Y51.0: Anticholinesterase agents

Anticholinesterase agents are medications that work by blocking the function of certain enzymes in the nervous system to help the body communicate more effectively with muscles and organs. Their use can be associated with numerous issues, as they can cause side effects or adverse reactions, collectively denoted by the ICD-10 code Y51.0. These medications are most commonly prescribed for conditions like Alzheimer's disease, myasthenia gravis, and glaucoma, among others. Reactions to anticholinesterase agents are typically dose-dependent, meaning that higher doses usually increase the risk of side effects. Common symptoms of an adverse reaction may include muscle cramps, increased salivation, nausea, and diarrhea. In severe cases, it may lead to a slow heart rate, blood pressure changes, or even breathing difficulties. The nature and severity of symptoms can vary significantly based on individual health conditions, age, other medications in use, and the specific anticholinesterase agent involved.
