Propiverine hydrochloride vs previous anticholinergic agents (For Overactive ...DR. JONATHAN D'SOUZA (PhD)This document discusses overactive bladder and compares the drug propiverine hydrochloride to previous anticholinergic agents for treating overactive bladder symptoms. It summarizes that propiverine has dual action as both an anticholinergic and calcium channel blocker. A clinical study of 73 patients compared propiverine to previous anticholinergic treatments and found that patients who completed the study on propiverine saw significant improvements in nighttime urinary frequency, urgency, and urgency incontinence. The document concludes that propiverine may be more effective than previous anticholinergic agents for some patients with overactive bladder.

Cholinergic drugs theaThea FresnozaThis document discusses cholinergic drugs and related agents. It defines cholinergic drugs as those that mimic or block the action of acetylcholine. The document outlines the cholinergic system including acetylcholine as a neurotransmitter, cholinergic receptors (nicotinic and muscarinic), and receptor subtypes. It also discusses cholinergic agonists, antagonists, stereochemistry, and inhibitors of the acetylcholinesterase enzyme. Specific drugs are provided as examples within each category.
Anticholinergics Med Chem Lecturesagar joshiAnticholinergics are drugs that inhibit the pharmacological response of acetylcholine (Ach) by competitively binding to and blocking muscarinic receptors. Their general structure consists of two carbocyclic or heterocyclic rings (R1 and R2) connected by a chain with an ester or ether group (X) and a basic nitrogen substituent. The R3 group can be hydrogen, hydroxyl, or hydroxymethyl. Maximum potency is seen with 2 carbon units between the ring and nitrogen. Older anticholinergics like atropine and scopolamine are non-selective for muscarinic receptor subtypes, while newer drugs show selectivity. Anticholinergics are used to treat
3.cholinergic drugsIAU DentThis document discusses the autonomic nervous system and cholinergic transmission. It describes how drugs can have parasympathomimetic or parasympatholytic effects by stimulating or opposing muscarinic receptors. There are three main types of muscarinic receptors (M1, M2, M3) located throughout the body. Drugs that stimulate muscarinic receptors can be direct acting parasympathomimetics or indirect acting via inhibiting acetylcholinesterase. Common cholinergic drugs and their effects/indications are also outlined.
Cholinergic agonists - medicinal chemistry updatedkaami16This document outlines a lecture on medicinal chemistry related to the cholinergic system. It will review concepts of acetylcholine mimetics and acetylcholinesterase inhibitors. For muscarinic agonists, it will discuss biosynthesis and metabolism of acetylcholine, structure activity relationship studies of various muscarinic agonists. For acetylcholinesterase inhibitors, it will cover the mechanism of acetylcholine hydrolysis, reversible and irreversible inhibitors, and the antidote for irreversible inhibitors. Learning objectives and resources are also provided.
Cholinergic antagonists medicinal chemistrykaami16This document provides an outline for a lecture on cholinergic antagonists. It will cover muscarinic antagonists, their therapeutic applications and structure-activity relationships. It will also cover nicotinic antagonists, including their use as neuromuscular blockers. The learning objectives are to understand the structures, uses and binding properties of various cholinergic antagonists, and how their chemical structures relate to their activities. Key topics include the pharmacophores of antimuscarinics, specific drugs from different classes, and differences between depolarizing and non-depolarizing neuromuscular blockers.
Cholinergic drugs pptpharma stuffThe seminar discusses cholinergic drugs, which affect the autonomic nervous system and are classified into muscarinic and nicotinic receptors based on their action. Key topics include the synthesis and release of acetylcholine, types of cholinergic agents, and their physiological effects, along with clinical applications in conditions such as glaucoma and myasthenia gravis. The document also covers the structure and modifications of these drugs, as well as references for further reading.
