Effect of physostigmine and atropine on DRC of acetylcholine using frog rectus abdominis muscle and rat ileum respectively

by

Aim:  Effect of physostigmine and atropine on DRC of acetylcholine using frog rectus abdominis muscle and rat ileum respectively. References: Objective: To study the effect of physostigmine and atropine on the dose-response curve (DRC) of acetylcholine (ACh) using isolated frog rectus abdominis muscle and rat ileum preparations. Principle: Acetylcholine (ACh) is a neurotransmitter that mediates … Read more

Parasympathomimetics, also known as cholinergic agonists or muscarinic agonists, are drugs that mimic the action of the parasympathetic nervous system by stimulating the cholinergic receptors. These receptors are predominantly found in various organs and tissues throughout the body, including the heart, smooth muscles, exocrine glands, and central nervous system. Classification of Parasympathomimetics Parasympathomimetics can be … Read more

Miotics, also known as cholinergic agonists, are a group of drugs that mimic the action of acetylcholine, a neurotransmitter in the parasympathetic nervous system. These drugs primarily act on the iris sphincter muscle and the ciliary muscle, leading to pupillary constriction (miosis) and accommodation (focusing on near objects). Classification Miotics can be classified into two … Read more

Cholinergic drugs are a class of medications that mimic or enhance the effects of acetylcholine. This neurotransmitter plays a vital role in the nervous system and the communication between nerve cells and muscles. Acetylcholine plays a role in various physiological processes, including muscle contraction, regulation of heart rate, gastrointestinal function, and memory. Cholinergic drugs can … Read more
