Understanding Anticholinergic Drugs Anticholinergic drugs, also known as cholinergic antagonists or blockers, inhibit the action of acetylcholine at cholinergic receptors. These drugs bind to nicotinic and muscarinic receptors but do not activate them. The key difference between agonists and antagonists is that while both have receptor affinity, only agonists possess intrinsic activity to stimulate intracellular signaling.
Classification of Anticholinergics These drugs are categorized based on their target: anti-muscarinic (blocking muscarinic receptors) and anti-nicotinic (targeting nicotinic channels). Anti-muscarinics can be selective for specific subtypes like M1 or M3 or non-selective such as atropine. Anti-nicotinics include ganglion blockers affecting neuronal synapses and neuromuscular junction inhibitors disrupting muscle contractions.
Mechanism Behind Muscarinic Blockers Muscle relaxation occurs when antimuscarinics block parasympathetic signals by inhibiting acetylcholine's effects on smooth muscles in organs like the heart, lungs, eyes, bladder & gastrointestinal tract—resulting in reduced secretions & motility alongside pupil dilation without accommodation ability due paralysis-induced cycloplegia symptoms seen clinically useful during ophthalmological exams/tests etcetera!
