Cholinergic Blocking Agents: Therapeutic Uses Gastrointestinal PSNS controls gastric secretions and smooth muscles that produce gastric motility. They block acetylcholine from binding to cholinergic receptors, namely the nicotinic and muscarinic receptors. An acetylcholinesterase inhibitor or anti-cholinesterase is a chemical that inhibits the cholinesterase enzyme from breaking down acetylcholine, so increasing both the level and duration of action of the neurotransmitter acetylcholine. These include cramps, increased salivation, lacrimation, muscular weakness, paralysis, muscular fasciculation, diarrhea, and blurry vision[1][2][0]. Cholinergic agents allow you to see due to the production of fluid that moisturizes the eyes and you can salivate because of the production of mucus. Anticholinergic Drugs INTRODUCTION Different cholinergically-innervated organs may display different sensitivities to muscarinic receptor antagonists --- ex: atropine pyridostigmine) cause bronchoconstriction via bronchial M2-receptor blockade and muscarinic M1 and M3 receptor activation. In radiographic film processing, the active agent in the fixer that clears undeveloped silver bromide crystals from the film. M-cholinoblockers are competitive antagonists of acetylcholine as well as other M-cholinoblockers in terms of postsynaptic M-cholinoreceptors. . Most of the muscarinic receptor antagonists, sometimes simply called "anticholinergic" drugs, are pharmacologically similar. Cholinergic blocking drugs are a group of drugs that block the action of acetylcholine (ACh), a neurotransmitter, in synapses of the cholinergic nervous system. Acetylcholine (ACh) is the primary neurotransmitter in the parasympathetic branch of the autonomic nervous system. List of anticholinergics Anticholinergics are only available with a doctor's prescription. Examples of common anticholinergics: Antimuscarinic agents Antipsychotics ( clozapine, quetiapine) [21] Atropine Benztropine Biperiden Chlorpheniramine Certain SSRIs ( Paroxetine) [21] Dicyclomine ( Dicycloverine) Dimenhydrinate [21] Diphenhydramine [21] Doxepin Doxylamine Flavoxate Glycopyrrolate Glycopyrronium Hyoscyamine Ipratropium Orphenadrine Effects of Anticholinergic Drugs Blocking the cholinergic stimulation of the PSNS allows unopposed action of the SNS. Nicotinic and muscarinic receptors are part of the cholinergic . In general, cholinergic effects or symptoms are like the 'digest and rest' while adrenergic effects are congruent to the 'fight or flight' response symptoms. This blocking occurs mainly at the synapse in the central and peripheral nervous system. 349,350 Anticholinergics were commonly employed in a number of conditions related to dystonia in the recent years. 3. a natural force or object producing or used for obtaining specific results: Many insects are agents of fertilization.

Results o Decreased secretions from the nose, mouth, pharynx, and bronchi o Relaxed smooth muscles in the bronchi and bronchioles 2. Acetylcholine that is released from a stimulated nerve fiber is then unable to bind to the receptor site and fails to produce a cholinergic effect. The importance is that the agent can bind the principal by contract or create liability if he/she causes injury while in the scope of the agency.
