PHYSOSTIGMINA Meaning and Definition

1. Physostigmine, also known by its generic name physostigmina, is a medication classified as a cholinesterase inhibitor. It primarily functions by inhibiting the activity of the enzyme acetylcholinesterase, which is responsible for breaking down the neurotransmitter acetylcholine in the body. By inhibiting this enzyme, physostigmine allows for higher levels of acetylcholine to accumulate and remain active in the synapses of the central and peripheral nervous systems.

   Physostigmine is commonly used in the treatment of a condition called anticholinergic toxicity, which occurs due to the excessive blockade of acetylcholine receptors in the brain. This condition can result from overdose or adverse reactions to certain medications, such as antipsychotics or antidepressants, and presents with symptoms like hallucinations, delirium, and agitation. Physostigmine helps alleviate these symptoms by increasing the levels of acetylcholine in the brain, thereby counteracting the effects of the blocked receptors.

   Additionally, physostigmine is also employed for the reversal of neuromuscular blockade following general anesthesia or during surgical procedures. It helps restore normal muscle function by temporarily inhibiting the breakdown of acetylcholine, improving muscle strength and promoting more efficient nerve-muscle signaling.

   Despite its therapeutic benefits, physostigmine does have potential side effects, including nausea, vomiting, diarrhea, increased sweating, and slow heart rate. It is important to administer this medication under medical supervision to ensure appropriate dosing and to monitor for any adverse reactions.

2. Physostigmine, eserine, an alkaloid of physostigma or Calabar bean.
