The synthesis, characterization, aggregation behavior, theoretical studies, and investigation of antimicrobial, antidiabetic, and anticholinergic properties of 4-(2-(5-amino-4-(4-bromophenyl)-3-methyl-1H-pyrazol-1-yl)ethoxy)phthalonitrile (2) and its soluble aminopyrazole-substituted peripheral metallo (Mn, Co, and Ni)-phthalocyanine complexes (3-5) are reported for the first time. The synthesized compounds and phthalocyanine complexes were characterized spectroscopically. The new phthalonitrile derivative (2) and its peripheral metallophthalocyanine complexes (3-5) were found to be effective inhibitors of α-glycosidase, acetylcholinesterase (AChE), human carbonic anhydrase I and II isoforms (hCA I and II), and butyrylcholinesterase (BChE) with Ki values in the range of 1...

Introduction: Usually, physostigmine is used as antidote for anticholinergic poisons in order to improve hemodynamics and cardiac output. In addition, it causes beneficial effects during sepsis when added timely. Here, we studied whether physostigmine improves hemodynamics when treatment during systemic inflammation was delayed. Methods: Two series of randomized studies with overall 44 rats were conducted. Systemic inflammation was induced by lipopolysaccharide (LPS) infusion (0...

Background: Penehyclidine hydrochloride (PHC) is an anticholinergic drug manufactured in China. It is used widely in clinics as a reversal agent in cases of organic phosphorus poisoning and as a preanesthetic medication. Compared with other anticholinergic agents, PHC confers substantial advantages. Here, in this review, we focus on its important clinical effects for organic phosphorus poisoning, preanesthetic medication, and the protective effects on certain visceral organs. Materials and methods: Our bibliographic sources include the PubMed and China National Knowledge Infrastructure (CNKI) databases, updated in March 2018...

WHAT IS KNOWN AND OBJECTIVE: Anticholinergic drug use has been associated with a risk of central and peripheral adverse effects. There is a lack of information on anticholinergic drug use in persons with diabetes. The aim of this study is to investigate anticholinergic drug use and the association between anticholinergic drug use and self-reported symptoms in older community-dwelling persons with and without diabetes. METHODS: The basic population was comprised of Finnish community-dwelling primary care patients aged 65 and older...

BACKGROUND: Anticholinergic drugs put elderly patients at a higher risk for falls, cognitive decline, and delirium as well as peripheral adverse reactions like dry mouth or constipation. Prescribers are often unaware of the drug-based anticholinergic burden (ACB) of their patients. This study aimed to develop an anticholinergic burden score for drugs licensed in Germany to be used by clinicians at prescribing level. METHODS: A systematic literature search in pubmed assessed previously published ACB tools...

BACKGROUND: Physostigmine and its analogues neostigmine, pyridostigmine and rivastigmine are carbamates nowadays used in many indications, including antidotal effects against antimuscarinic poisonings, reversal of competitive neuromuscular block, myasthenia gravis, Alzheimer's disease and prophylaxis against nerve agent intoxications. Use of these medicinal carbamates, but also of carbamate insecticides, created need for research into the potential and mechanisms of action of several antidotes against carbamate poisonings, including anticholinergics and oximes...

Penehyclidine hydrochloride (PHC), a type of hyoscyamus drug, has both antimuscarinic and antinicotinic activities and retains potent central and peripheral anticholinergic activities. Compared with other hyoscyamine, the notable advantage of PHC is that it has few M2 receptor-associated cardiovascular side effects. Recent studies and clinical trials have suggested that treatment with penehyclidine hydrochloride may also possess good effects in the treatment of lung injury. The mechanism responsible for this effect has yet to be determined; however, one possibility is that they might do so by a direct effect on pulmonary vascular endothelium...

BACKGROUND: On the basis of the importance of the enteric nervous system (ENS) in gastrointestinal motility, we hypothesized that the ENS may mediate the therapeutic efficacy of electro-acupuncture (EA) in constipation by regulating the mechanisms underlying the effects of EA on gastrointestinal function. METHODS: Model mice with constipation were generated by gastric instillation of 0-4°C normal saline. Defecation time and stool (form and wet and dry weight) were assessed...

Organophosphates (OPs) are cholinesterase inhibitors that lead to a characteristic toxidrome of hypersecretion, miosis, dyspnea, respiratory insufficiency, convulsions and, without proper and early antidotal treatment, death. Most of these compounds are highly lipophilic. Sulfur mustard is a toxic lipophilic alkylating agent, exerting its damage through alkylation of cellular macromolecules (e.g., DNA, proteins) and intense activation of pro-inflammatory pathways. Currently approved antidotes against OPs include the peripheral anticholinergic drug atropine and an oxime that reactivates the inhibited cholinesterase...

PURPOSE: Some drugs have anticholinergic activity and can cause peripheral or central side effects. Several scales exist to evaluate the potential anticholinergic effect of prescribed drugs but: (i) they are validated in the elderly and mainly assess the cognitive side effect of treatments; (ii) they do not concern some of the drugs frequently used in clinical psychiatry in France. The aim of our study is to develop a new scale, the anticholinergic impregnation scale (AIS), with drugs used in France and based on an assessment of the drugs used against peripheral anticholinergic adverse effects...

Available cholinergic drugs for treating Alzheimer's disease (AD) provide modest symptomatic benefit. We hypothesized that co-administration of a peripheral anticholinergic to reduce dose-limiting adverse effects (AEs) would enable the safe/tolerable use of higher cholinesterase inhibitor doses and thus improve their antidementia efficacy. A modified single-blind, ascending-dose, phase IIa study of donepezil plus solifenacin (CPC-201) lasting 26 weeks was conducted in 41 patients with probable AD of moderate severity...

BACKGROUND: While primary hyperhidrosis can be seen in men, accompanying hot flushes is rarely seen in men. Primary hyperhidrosis is thought to be related to overactivity of the sympathetic nervous system while hot flushes are believed to be related to altered peripheral vascular reactivity and a narrowed thermoregulatory zone. CASE PRESENTATION: I report the case of a 29-year-old man of Arab origin who presented to a dermatology clinic with a complaint of generalized sweating, with heavier involvement of his inguinal region, axilla, and lower back...

RATIONALE: Anticholinergic medications largely exert their effects due to actions on the muscarinic receptor, which mediates the functions of acetylcholine in the peripheral and central nervous systems. In the central nervous system, acetylcholine plays an important role in the modulation of movement. OBJECTIVE: This study investigated the effects of over-the-counter medications with varying degrees of central anticholinergic properties on fixation stability, saccadic response time and the dynamics associated with this eye movement during a temporally-cued visual reaction time task, in order to establish the significance of central cholinergic pathways in influencing eye movements during reaction time tasks...

Acetylcholine is present in the peripheral and central nervous system, where it is involved in a number of fundamental physiological and biochemical processes. In particular, interaction with muscarinic receptors can cause adverse effects such as dry mouth, drowsiness, mydriasis and cognitive dysfunction. Despite the knowledge that exists regarding these common side-effects, little is known about how anticholinergic medications influence central motor processes and fine motor control in healthy individuals...

In the motor system, botulinum toxin type A (BoNT/A) actions were classically attributed to its well-known peripheral anticholinergic actions in neuromuscular junctions. However, the enzymatic activity of BoNT/A, assessed by the detection of cleaved synaptosomal-associated protein 25 (SNAP-25), was recently detected in motor and sensory regions of the brainstem and spinal cord after toxin peripheral injection in rodents. In sensory regions, the function of BoNT/A activity is associated with its antinociceptive effects, while in motor regions we only know that BoNT/A activity is present...

Primary Sjögren's syndrome (pSS) is a relatively common autoimmune systemic rheumatic disease. In addition to sicca syndrome and swollen salivary glands, systemic features manifest in the majority of patients, and are severe in 15%, particularly affecting the joints, skin, lungs, and peripheral nervous system. A recent meta-analysis estimated a pooled relative risk of 13.76 for the development of non-Hodgkin lymphoma, particularly in pSS patients who have parotid enlargement, vasculitis, cryoglobulinemia, and antibodies to Ro and La...

Constipation is a common and often debilitating condition in the elderly, which may be caused by underlying disease conditions, structural abnormalities in the bowel, and a variety of medications such as anticholinergics, antidepressants, and opiates. In this review, we focus on opioid-induced constipation (OIC), which is often underrecognized and undertreated in the elderly. When opioid therapy is initiated, healthcare providers are encouraged to evaluate risk factors for the development of constipation as part of a thorough patient history...

In cases of organophosphate poisoning, patients are treated with a combination of antidotes. In addition to these poison-directed antidotes, patients may require extra oxygen and artificial ventilation; other modalities may also be needed due to the wide range of toxic effects. Anisodamine is a belladonna alkaloid, and like other drugs from this family is non subtype-selective muscarinic, and a nicotinic cholinoceptor antagonist, which has been employed in traditional Chinese medicine. As a muscarinic antagonist, it displays similar pharmacological effects to atropine and scopolamine...

INTRODUCTION: Anticholinergics are a class of medicines that block the neurotransmitter, acetylcholine, in the brain and peripheral tissues. Medicines with anticholinergic activity are widely prescribed for and used by older people for various medical conditions. One-third to one-half of the medicines commonly prescribed for older people have anticholinergic activity. Several studies have reported anticholinergic burden to be a predictor of cognitive and functional impairments in older people...

Ischemic colitis is the most common subtype of intestinal ischemia usually resulting from vasospasm, vessel occlusion or mesenteric hypoperfusion. Neuroleptics have seldom been linked to ischemic colitis by blocking peripheral anticholinergic and antiserotonergic receptors inducing severe gastrointestinal paresis. We report a young patient with severe ischemic colitis requiring surgery due to necrosis of the bowel. After exclusion of other potential causes, olanzapine was admitted as the cause of ischemia. Clinicians should be aware of how to recognize and treat the potentially life-threatening effects of neuroleptics...
