Etiopathogenesis: The exact cause of Alzheimer’s disease is not fully understood, but it … 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
Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterized by muscle weakness and fatigue. It results from the production of autoantibodies that target and disrupt the function of acetylcholine receptors at the neuromuscular junction, impairing nerve-to-muscle signal transmission. Classification Medications used in the treatment of myasthenia gravis can be categorized into the following groups: 1. … 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
