Cholinergic and GABAergic regulation of nitric oxide synthesis in the guinea pig ileum. (1/496)

Nitric oxide (NO) synthesis was examined in intact longitudinal muscle-myenteric plexus preparations of the guinea pig ileum by determining the formation of [3H]citrulline during incubation with [3H]arginine. Spontaneous [3H]citrulline production after 30 min was 80-90 dpm/mg, which constituted approximately 1% of the tissue radioactivity. Electrical stimulation (10 Hz) led to a threefold increase in [3H]citrulline formation. Removal of calcium from the medium or addition of NG-nitro-L-arginine strongly inhibited both spontaneous and electrically induced production of [3H]citrulline. TTX reduced the electrically induced but not spontaneous [3H]citrulline formation. The electrically induced formation of [3H]citrulline was diminished by (+)-tubocurarine and mecamylamine and enhanced by scopolamine, which suggests that endogenous ACh inhibits, via muscarinic receptors, and stimulates, via nicotinic receptors, the NO synthesis in the myenteric plexus. The GABAA receptor agonist muscimol and GABA also reduced the electrically evoked formation of [3H]citrulline, whereas baclofen was without effect. Bicuculline antagonized the inhibitory effect of GABA. It is concluded that nitrergic myenteric neurons are equipped with GABAA receptors, which mediate inhibition of NO synthesis.  (+info)

Cholinergic blockade inhibits gastro-oesophageal reflux and transient lower oesophageal sphincter relaxation through a central mechanism. (2/496)

BACKGROUND: Atropine, an anticholinergic agent with central and peripheral actions, reduces gastro-oesophageal reflux (GOR) in normal subjects and patients with gastro-oesophageal reflux disease (GORD) by inhibiting the frequency of transient lower oesophageal sphincter relaxation (TLOSR). AIMS: To compare the effect of methscopolamine bromide (MSB), a peripherally acting anticholinergic agent, with atropine on the rate and mechanism of GOR in patients with GORD. METHODS: Oesophageal motility and pH were recorded for 120 minutes in 10 patients with GORD who were studied on three separate occasions. For the first two recording periods, either atropine (15 microg/kg bolus, 4 microg/kg/h infusion) or saline were infused intravenously. MSB (5 mg orally, four times daily) was given for three days prior to the third recording period. RESULTS: Atropine significantly reduced basal LOS pressure (12.6 (0.17) mm Hg to 7.9 (0.17) mm Hg), and the number of TLOSR (8.1 (0.56) to 2.8 (0. 55)) and reflux episodes (7.0 (0.63) to 2.0 (0.43)) (p<0.005 for all comparisons). MSB reduced basal LOS pressure (12.6 (0.17) to 8.7 (0. 15) mm Hg, p<0.005), but had no effect on the frequency of TLOSR (8. 1 (0.56) to 7.5 (0.59)) and reflux episodes (7.0 (0.63) to 4.9 (0. 60)) (p>0.05). CONCLUSION: In contrast to atropine, MSB has no effect on the rate of TLOSR or GOR in patients with GORD. Atropine induced inhibition of TLOSR and GOR is most likely mediated through a central cholinergic blockade.  (+info)

Cardiovascular phenotype and temperature control in mice lacking thyroid hormone receptor-beta or both alpha1 and beta. (3/496)

We have used a telemetry system to record heart rate, body temperature, electrocardiogram (ECG), and locomotor activity in awake, freely moving mice lacking thyroid hormone receptor (TR)-beta or TR-alpha1 and -beta (TR-alpha1/beta). The TR-alpha1/beta-deficient mice had a reduced heart rate compared with wild-type controls. The TR-beta-deficient mice showed an elevated heart rate, which, however, was unresponsive to thyroid hormone treatment regardless of hormonal serum levels. ECG revealed that the TR-beta-deficient mice had a shortened Q-Tend time in contrast to the TR-alpha1/beta-deficient mice, which exhibited prolonged P-Q and Q-Tend times. Mental or pharmacological stimulation of the sympathetic nervous system resulted in a parallel increase in heart rate in all animals. A single injection of a nonselective beta-adrenergic-receptor blocker resulted in a parallel decrease in all mice. The TR-alpha1/beta-deficient mice also had a 0.4 degrees C lower body temperature than controls, whereas no difference was observed in locomotor activity between the different strains of mice. Our present and previous results support the hypothesis that TR-alpha1 has a major role in determining heart rate under baseline conditions and body temperature and that TR-beta mediates a hormone-induced increase in heart rate.  (+info)

Activation of nicotinic acetylcholine receptors patterns network activity in the rodent hippocampus. (4/496)

1. Intracellular and extracellular recordings from area CA3 of rat and mouse hippocampal slices revealed two distinct modes of synchronous network activity in response to continuous application of muscarinic acetylcholine receptor (mAChR) agonists. At low concentrations (e.g. 0.1-1 microM oxotremorine-M), 'burst-mode' activity comprised regular individual AMPA receptor-mediated depolarizing events, each generating several action potentials. At higher concentrations (5-50 microM), 'theta-mode' prevailed in which ordered clusters of depolarizing theta-frequency oscillations occurred. 2. Whilst theta-mode activity was abolished by the mAChR antagonist atropine (5 microM), the nicotinic acetylcholine receptor (nAChR) antagonists tubocurarine (100 microM), mecamylamine (100-500 microM) and dihydro-beta-erythroidine (250 microM) converted this mode of activity to burst-mode. 3. Likewise, disruption of synaptically available ACh using inhibitors of choline uptake (hemicholinium-3; 20-50 microM) or vesicular ACh transport (vesamicol; 50 microM) converted theta-mode into burst-mode activity. 4. Hippocampal slices prepared 2-3 weeks after transection of the primary cholinergic efferent pathway from the medial septum exhibited reduced vesicular ACh transporter immunoreactivity but still supported nAChR-dependent theta-mode activity suggesting that ACh released from this pathway was not critical for the activation of these receptors. 5. In summary, ACh-mediated activation of nAChRs tailors the pattern of network activity into theta-frequency depolarizing episodes as opposed to synchronized individual events at much lower frequencies.  (+info)

Pharmacokinetic and pharmacodynamic characterization of OROS and immediate-release amitriptyline. (5/496)

AIMS: To characterize the pharmacokinetics of amitriptyline and its metabolite nortriptyline following OROS and IR treatments, and to correlate them with anticholinergic side-effects. METHODS: The pharmacokinetics and safety of amitriptyline following administration of an osmotic controlled release tablet (OROS and an immediate release (IR) tablet were evaluated in 14 healthy subjects. In this randomized, open label, three-way crossover feasibility study, the subjects received a single 75 mg OROS tablet, three 25 mg IR tablets administered every 8 h, or 3x25 mg IR tablets administered at nighttime. In each treatment arm serial blood samples were collected for a period of 84 h after dosing. The plasma samples were analysed by gas chromatography for amitriptyline and its metabolite nortriptyline. Anticholinergic effects such as saliva output, visual acuity, and subject-rated drowsiness and dry mouth were measured on a continuous scale during each treatment period. RESULTS: Following dosing with OROS (amitriptyline hydrochloride), the mean maximal plasma amitriptyline concentration Cmax (15.3 ng ml-1 ) was lower and the mean tmax (25.7 h) was longer than that associated with the equivalent IR dose administered at nighttime (26.8 ng ml-1 and 6.3 h, respectively). The bioavailability of amitriptyline following OROS dosing was 95% relative to IR every 8 h dosing, and 89% relative to IR nighttime dosing. The metabolite-to-drug ratios after the three treatment periods were similar, suggesting no change in metabolism between treatments. The relationships between plasma amitriptyline concentration and anticholinergic effects (e.g. reduced saliva weight, dry mouth, and drowsiness) were similar with all three treatments. Of the anticholinergic effects, only decreased saliva weight and dry mouth correlated well with plasma amitriptyline concentrations; drowsiness did not. There was no apparent correlation between anticholinergic effects and the plasma nortriptyline concentration. CONCLUSIONS: The bioavailability of OROS (amitriptyline hydrochloride) was similar to that of the IR treatments and the pharmacokinetics of amitriptyline after OROS dosing may decrease the incidence of anticholinergic effects compared with that seen with nighttime dosing of the IR formulation. Therefore, this controlled-release formulation of amitriptyline may be appropriate for single daily administration.  (+info)

Venous hydrostatic indifference point as a marker of postnatal adaptation to orthostasis in swine. (6/496)

The postulate that venous adaptation assists postural baroreflex regulation by shifting the hydrostatic indifference point (HIP) toward the heart was investigated in eight midazolam-sedated newborn piglets. Whole body head-up (+15, +30, and +45 degrees ) and head-down (-15 and -30 degrees ) tilt provided a physiological range of orthostatic strain. HIP for all positive tilts shifted toward the heart (P < 0.05), +45 degrees HIP shifted most [6.7 +/- 0.3, 5.9 +/- 0.5, and 3.6 +/- 0.3 (SE) cm caudal to right atrium on days 1, 3, and 6, respectively]. HIP for negative tilts (3.0 +/- 0.2 cm caudal to right atrium) did not shift with postnatal age. Euthanasia on day 6 caused 2.1 +/- 0.3-cm caudal displacement of HIP for positive and negative tilts (P < 0.05). HIP proximity to right atrium was not altered by alpha-, beta-adrenoceptor and cholinoceptor blockade on day 5. It is concluded that early HIP migration reflects enhancement of venous pressure control to head-up orthostatic strain. The effect is independent of baroreflex-mediated adrenoceptor and cholinoceptor mechanisms.  (+info)

Blockage of mouse muscle nicotinic receptors by serotonergic compounds. (7/496)

Xenopus laevis oocytes were used to analyse the effects of serotonin (5-hydroxytryptamine, 5-HT) and serotonergic agents on ionic currents elicited by the activation of mammalian muscle nicotinic acetylcholine receptors (AChRs). 5-HT as well as other serotonergic agents, such as ketanserin, 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), methysergide, spiperone, or fluoxetine alone (up to 1 mM), did not elicit membrane currents in Xenopus oocytes expressing AChRs, but they reversibly reduced the current elicited by acetylcholine (ACh-current). Serotonin was applied before, together with or after ACh application, and its effects were examined on desensitizing and non-desensitizing ACh-currents. 5-HT reduced the amplitude and accelerated the desensitization of the desensitizing currents. In contrast, non-desensitizing currents were reduced in amplitude but their time course was not significantly affected. With the same concentration of 5-HT the inhibition was stronger on desensitizing than on non-desensitizing ACh-currents. For example, 100 microM 5-HT reduced the peak of a desensitizing ACh-current to 0. 48 +/- 0.06 (peak current ratio) and after 40 s the current was reduced to a ratio of 0.25 +/- 0.04, whereas a non-desensitizing ACh-current was reduced to a ratio of 0.66 +/- 0.01. All the serotonergic agents tested inhibited the ACh-currents rapidly and reversibly, suggesting that they are acting directly on the AChRs. The half-inhibitory concentration, IC50, of 5-HT acting on non-desensitizing currents elicited by 250 nM ACh was 247 +/- 26 microM and the Hill coefficient was 0.88, suggesting a single site for the interaction of 5-HT with the receptor. It appears that 5-HT inhibits AChRs non-competitively because neither the half-effective concentration of ACh, EC50, for ACh-current nor the Hill coefficient were affected by 5-HT. Furthermore, the extent of inhibition of 5-HT on AChRs did not depend on the nicotinic agonist (suberyldicholine, ACh or nicotine). The inhibition of AChRs by serotonergic agents was voltage-dependent. The electrical distance of the binding site for 5-HT was 0.75, whereas for the other serotonergic agents tested it was 0.22, suggesting that ketanserin, 8-OH-DPAT, methysergide, spiperone and fluoxetine act within the ion channel, but at a site more external than that for 5-HT. These substances inhibited the ACh-current more potently than 5-HT. We conclude that 5-HT and serotonergic agents inhibit, in a non-competitive manner, the ACh-current in muscle AChRs by blocking the open receptor-channel complex. Moreover, 5-HT appears to promote the desensitized state of the receptor when the current is elicited by high ACh concentrations.  (+info)

Acute effect of pretreatment with single conventional dose of salmeterol on dose-response curve to oxitropium bromide in chronic obstructive pulmonary disease. (8/496)

BACKGROUND: An earlier study documented that, in patients with chronic obstructive pulmonary disease (COPD), addition of ipratropium bromide at the clinically recommended dose (40 microg) does not produce any further bronchodilation than that achieved with salmeterol 50 microg alone. However, the dose of ipratropium bromide needed to produce near maximal bronchodilation is several times higher than the customary dosage. The full therapeutic potential of combined salmeterol plus an anticholinergic drug can therefore only be established using doses higher than those currently recommended in the marketing of these agents. A study was undertaken to examine the possible acute effects of higher than conventional doses of an anticholinergic agent on the single dose salmeterol induced bronchodilation in patients with stable and partially reversible COPD. METHODS: Thirty two outpatients received 50 microg salmeterol or placebo. Two hours after inhalation a dose-response curve to inhaled oxitropium bromide (100 microg/puff) or placebo was constructed using one puff, one puff, two puffs, and two puffs-that is, a total cumulative dose of 600 microg oxitropium bromide. Dose increments were given at 20 minute intervals with measurements being made 15 minutes after each dose. On four separate days all patients received one of the following: (1) 50 microg salmeterol + 600 microg oxitropium bromide; (2) 50 microg salmeterol + placebo; (3) placebo + 600 microg oxitropium bromide; (4) placebo + placebo. RESULTS: Salmeterol induced a good bronchodilation (mean increase 0.272 l; 95% CI 0.207 to 0.337) two hours after its inhalation. Oxitropium bromide elicited an evident dose-dependent increase in forced expiratory volume in one second (FEV(1)) and this occurred also after pretreatment with salmeterol with a further mean maximum increase of 0.152 l (95% CI of differences 0.124 to 0.180). CONCLUSIONS: This study shows that acute pretreatment with 50 microg salmeterol does not block the possibility of inducing more bronchodilation with an anticholinergic agent when a higher than normal dosage of the muscarinic antagonist is used.  (+info)

Delirium increases morbidity, mortality and healthcare costs especially in the elderly. Serum anticholinergic activity (SAA) is a suggested biomarker for anticholinergic burden and delirium risk, but the association with cerebral cholinergic function remains unclear. To clarify this relationship, we prospectively assessed the correlation of SAA with quantitative electroencephalography (qEEG) power, delirium occurrence, functional and cognitive measures in a cross-sectional sample of acutely hospitalized elderly (| 80 y) with high dementia and delirium prevalence. 61 consecutively admitted patients over 80 years underwent an extensive clinical and neuropsychological evaluation. SAA was determined by using radio receptor assay as developed by Tune, and standard as well as quantitative EEGs were obtained. 15 patients had dementia with additional delirium (DD) according to expert consensus using DSM-IV criteria, 31 suffered from dementia without delirium (D), 15 were cognitively unimpaired (CU). SAA was
Older people are particularly vulnerable to adverse cognitive effects and risk of dementia following exposure to medicines with anticholinergic activity;1 however, the biological basis for these effects remains unclear.2 The risk of anticholinergic adverse effects increases with age, polypharmacy, comorbidities, pre-existing cognitive impairment, cholinergic neuronal degeneration and changes in pharmacokinetic and pharmacodynamic properties. This study examined whether medicines with anticholinergic activity alter brain glucose metabolism, and the impact this has on brain structure, function and cognitive decline. ...

Recent evidence has shown a greater risk of dementia, in particular Alzheimers disease (AD), in individuals using anticholinergic medications regularly. These drugs are widely used by older adults to treat bladder dysfunction, mood, and pain, and many of them are available without prescription. Since these drugs are often used to treat both motor symptoms and non-motor symptoms in patients with Parkinsons Disease (PD), there is concern for increased risk of dementia. Contrary to expectations, a study in the current issue of the Journal of Parkinsons Disease determined that the cognitive performance of PD patients taking anticholinergic medications did not differ from those who did not.. Principal investigator David J. Burn, Director of the Institute of Neuroscience and Professor of Movement Disorder Neurology at Newcastle University, UK, explained, This is the first study to explore an association between anticholinergic burden and mild cognitive impairment (MCI) in PD participants, and is ...
Background Cognitive decline is common in Parkinsons disease (PD). Although some of the aetiological factors are known, it is not yet known whether drugs with anticholinergic activity (AA) contribute to this cognitive decline. Such knowledge would provide opportunities to prevent acceleration of cognitive decline in PD.. Objective To study whether the use of agents with anticholinergic properties is an independent risk factor for cognitive decline in patients with PD.. Methods A community-based cohort of patients with PD (n=235) were included and assessed at baseline. They were reassessed 4 and 8 years later. Cognition was assessed using the Mini-Mental State Examination (MMSE). A detailed assessment of the AA of all drugs prescribed was made, and AA was classified according to a standardised scale. Relationships between cognitive decline and AA load and duration of treatment were assessed using bivariate and multivariate statistical analyses.. Results More than 40% used drugs with AA at ...

A case report in the December 5 issue of the New England Journal of Medicine presents an example of the potential dangers of anticholinergic drugs in some patients: short-term memory loss and hallucinations.. Anecdotally, many specialists are aware that drugs with anticholinergic properties can cause neuropsychological deficits. There is even evidence from a study by Elaine Perry and colleagues (Perry et al., 2003) that these drugs-including common drugs for incontinence, hypertension, psychosis, mood disorders, even allergies-might contribute to the pathology of Alzheimers disease (see ARF related news story). Still, physicians have to help their patients balance quality-of-life issues, and for many people, these drugs are of great benefit..

It is important to differentiate transient, fluctuating disturbances in consciousness due to a delirium from an underlying memory disorder. Many medications can induce confusion or even delirium in the elderly; for example, the greater the number of anticholinergic medications a patient is taking, the greater the risk of hospitalisation for confusion or dementia. [3] Kalisch Ellett LM, Pratt NL, Ramsay EN, et al. Multiple anticholinergic medication use and risk of hospital admission for confusion or dementia. J Am Geriatr Soc. 2014;62:1916-1922. http://www.ncbi.nlm.nih.gov/pubmed/25284144?tool=bestpractice.com The history, examination, and neuropsychological testing can all be helpful in distinguishing a primary memory disorder from a delirium or impairment in retrieval.

on a cognitive test and 1.1-percent on a measure of routine activities one can perform for themselves (another measure of intact cognition). Unfortunately, cognitive decline that is due to anticholinergic medications is often overlooked because most medications listed in the accompanying Table would not necessarily, alone, account for a striking decline in memory or other cognitive function. But, the cumulative impact of consuming multiple medications with anticholinergic effects may be significant, resulting in unnecessary distress among patients, families and physicians alike. While these findings are only preliminary, they permit physicians and patients to semi-quantitatively account for the anticholinergic effects of a patients medications when the patient complains of memory and other cognitive problems. If you are suffering from a troubling decline in one of your cognitive functions, the first thing you and your physician should do is take a look at your medication list. The answer may be ...

An anticholinergic agent is a substance that blocks the neurotransmitter acetylcholine in the central and the peripheral nervous system. These agents inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells. The nerve fibers of the parasympathetic system are responsible for the involuntary movement of smooth muscles present in the gastrointestinal tract, urinary tract, lungs, and many other parts of the body. Anticholinergics are divided into three categories in accordance with their specific targets in the central and peripheral nervous system: antimuscarinic agents, ganglionic blockers, and neuromuscular blockers. Anticholinergic drugs are used to treat a variety of conditions: Dizziness (including vertigo and motion sickness-related symptoms) Extrapyramidal symptoms, a potential side-effect of antipsychotic medications. Gastrointestinal disorders (e.g., peptic ulcers, diarrhea, pylorospasm, diverticulitis, ...

Anticholinergic ( anticholinergic agent) is a group of substances that blocks the action of the neurotransmitter acetylcholine (ACh) at synapses in the central and the peripheral nervous system, and, in broad terms, neuromuscular junction.[1][2] These agents inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells. The nerve fibers of the parasympathetic system are responsible for the involuntary movement of smooth muscles present in the gastrointestinal tract, urinary tract, lungs, and many other parts of the body;[3] cholinergic process otherwise by enhancing ACh function.[3] In broad terms, anticholinergics are divided into two categories in accordance with their specific targets in the central, peripheral nervous system and neuromuscular junction:[3] antimuscarinic agents, and antinicotinic agents (ganglionic blockers, neuromuscular blockers).[4] In strict terms, anticholinergic only comprises ...
Fezolamine [N,N-dimethyl-3,4-diphenyl-1H-pyrazole-1-propanamine-(E)-2- butenedioate] is a new, nontricyclic agent under investigation as a potential antidepressant. In vitro, it was 3 to 4 times more selective in blocking synaptosomal uptake of [3H]norepinephrine than uptake of [3H]serotonin or [3H]dopamine. In classical behavioral tests using monoamine-depleted animals, it prevented the depressant effects of reserpine and tetrabenzine. In addition, it was active in the behavioral despair procedure. Its potency in three of these models was similar to that of standard tricyclics (e.g., imipramine, amitriptyline) or newer nontricyclic antidepressants (e.g., bupropion). In the mouse mydriasis and oxotremorine antagonism models, anticholinergic properties of fezolamine were weak or absent compared with imipramine and amitriptyline. Locomotor activity in mice was not increased by fezolamine at doses 2 to 16 times greater than effective antidepressant doses, suggesting the absence of central nervous ...

Many commonly used drugs have anticholinergic effects, meaning the drugs block the action of acetylcholine. Nerve cells release acetylcholine to transmit impulses to other nerves in the brain and throughout the body. Previous research has shown a link between these drugs and dementia. Now a study has found a similar link with mild cognitive impairment (MCI), especially if you take larger doses. Th

COPD is a major cause of morbidity and mortality with a rising incidence worldwide. Large RCTs and meta-analyses show that currently available pharmacotherapy may improve symptoms and perhaps even survival. Appleton and colleagues provided an in-depth systematic review of the role of LABAs in the management of stable COPD. LABAs led to small statistically significant increases in lung function (FEV1) and improvement in some measures of health status compared with placebo. These findings further support current guideline recommendations for use of LABAs in stable moderate-to-severe COPD. However, the story does not end here. In light of recent concerns and the continued debate about LABAs and increased asthma-related deaths (1), is it possible that LABAs also increase deaths in patients with COPD? The meta-analysis by Salpeter and colleagues shows the effectiveness of anticholinergics in reducing COPD exacerbations and hospitalizations. Interestingly, compared with placebo, anticholinergics ...

This observational case control study has demonstrated no relationship between anticholinergic burden and polypharmacy, with delirium in older people admitted to an acute hospital. Increasing age is actually associated with reduced number of drugs taken, and only taking anticholinesterase inhibitor drugs are associated with delirium. As expected the majority of older patients in this study were taking a large number of medications, median 7 drugs, and 73 % were exposed to at least one medication with anticholinergic effects. We found no relationship between either of the anticholinergic drug scales used in this study, ACB and ADS, and prevalent delirium on admission to hospital. We also found no association between the number of drugs patients were prescribed, or the presence of polypharmacy and prevalent delirium. Use of Acetylcholinesterase inhibitors was associated with delirium. Delirium is more common in patients with dementia [3] and this likely explains the correlation. However, ...

The effects of Tiotropium Bromide last for 24 hours. This type of anticholinergic bronchodilator medication that is popularly used to help patients manage their COPD condition including emphysema. The main use of Tiotropium Bromide is to control and prevent the known symptoms of COPD including shortness of breath and wheezing. Since this offers 24-hour relief, the muscles get to relax and breathing becomes normal or at least close to it.. Emphysema makes breathing more difficult for the patients and thus, this strains the muscles that are responsible for breathing. With the aid of Tiotropium Bromide, these muscles are put into relaxation mode, so that the airways open up. This results to more comfortable and easier breathing. When Tiotropium Bromide is used regularly, the effects of this medication become even more effective. Remember that this will not work right away and doctors as well as medical organizations agree that this should not be used to remedy sudden problems with breathing. The ...

Anticholinergic drugs reduce the bladder detrusor muscle contractions and are used to treat urgency incontinence and symptoms of overactive bladder. Due to sex differences in etiology of these symptoms, drug therapy differs as urinary retention must be ruled out before starting treatment with anticholinergic drugs. In women,anticholinergic drugs are commonly used when non-pharmacological treatments such as bladder training are insufficient. In men, benign prostate hyperplasia is a common cause of urgency symptoms. Non-anticholinergic drugs, primarily alpha-1 blockers, are therefore often used as first-line treatment in men even though anticholinergic drugs are used in addition or as monotherapy [1-3].. The baseline symptoms described in studies differ between men and women regarding prevalence of incontinence episodes and frequency of urgency episodes [4, 5]. Treatment effects on these parameters are common outcomes in clinical studies and differences in treatment effect between men and women ...
Research from the Regenstrief Institute, the Indiana University Center for Aging Research and Wishard-Eskenazi Health on medications commonly taken by older adults has found that drugs with strong anticholinergic effects cause cognitive impairment when taken continuously for as few as 60 days. A similar impact can be seen with 90 days of continuous use when taking multiple drugs with weak anticholinergic effect.
Natural News) If youre looking to reduce your risk of dementia, you might be increasing your intake of blueberries and omega-3 rich foods, but a new study shows another very important step you should take: avoid anticholinergic medication.. Anticholinergic drugs are given to people for symptoms such as bladder problems, gastrointestinal disorders, Parkinsons disease, allergies and chronic obstructive pulmonary disease. They contract and relax muscles and work by blocking acetylcholine, which transmits messages through the nervous system.. Although these drugs are already known to cause confusion and memory loss among their short-term side effects, researchers wanted to find out if long-term use could raise peoples risk of developing dementia.. Scientists from the University of Nottingham looked at nearly 59,000 patients to explore the link. The people they studied were 82 years old on average, and 63 percent of them were women. They matched each dementia patient with five control patients who ...

Asthma, the most common chronic condition among children, is operationally defined as recurrent wheezing and/or persistent coughing in a setting where asthma is likely and other rare conditions have been excluded. Other definitions describe airway inflammation with eosinophilic and mast cell predominance, bronchial hyperresponsiveness, and reversible airflow limitation resulting in recurrent cough and wheeze. Wide mismatches still exist among children between disease severity and adequacy of treatment. Morris and Mellis used an evidence-based technique to answer three major questions about the management of childhood asthma.. First, they looked at the usefulness of adding a nebulized anticholinergic agent (ipratropium bromide) to nebulized beta-agonist therapy in the treatment of acute asthma in children. The main results showed that a single dose of a nebulized anticholinergic agent did not reduce the incidence of hospital admissions. In children with moderate to severe asthma, multiple ...
In 2009 the U.S. Food and Drug Administration (FDA) placed a black box warning on metoclopramide (MCP) due to the increased risks and prevalence of tardive dyskinesia (TD). In this study, we developed a multi-step biomedical informatics screening (MSBIS) approach leveraging publicly available bioactivity and drug safety data to identify concomitant drugs that mitigate the risks of MCP-induced TD. MSBIS includes (1) TargetSearch (http://dxulab.org/software) bioinformatics scoring for drug anticholinergic activity using CHEMBL bioactivity data; (2) unadjusted odds ratio (UOR) scoring for indications of TD-mitigating effects using the FDA Adverse Event Reporting System (FAERS); (3) adjusted odds ratio (AOR) re-scoring by removing the effect of cofounding factors (age, gender, reporting year); (4) logistic regression (LR) coefficient scoring for confirming the best TD-mitigating drug candidates ...
Basic substituted benzilic esters with distinctive anticholinergic effects are potential drugs for the treatment of urinary incontinence, duodenal and gastric ulcers and Parkinson disease. Derivatives of benzilic esters, exhibiting a combination of anticholinergic and dopaminergic effects, are of special interest because, as a consequence of their dualistic effect, they are in a position to form a new class of Antiparkinson drugs. As muscarinic receptor subtypes possess a large variety of functional properties, drugs which show less selectivity on muscarinic receptors exhibit atropine-like side effects. A reduction of these side effects may be achieved by the development of more selective anticholinergic compounds. The objective was to optimise the effect of N-Methyl-4-piperidyl benzilates through a variation of sterical parameters and the introduction of electronically differentiated substituents within the aromatic rings. The effect of sterical and structural variations was investigated in ...

  • The present studies examined the possibility that an antagonist action at a particular receptor subtype might be responsible for the interaction between PCP and the clozapine-like antipsychotics by testing whether a selective antagonist at alpha -1, alpha -2, M1 or GABA-A receptors would prevent the PCP-induced deficit in PPI in rats. (aspetjournals.org)
  • The antagonists for alpha -2, for M1 and for GABA-A receptors had no effect on base-line PPI or on PCP-induced disruptions in PPI. (aspetjournals.org)
  • Autonomic receptors are broadly divided into those for ACh (cholinergic receptors) and those for catecholamines such as NE or EPI (adrenergic receptors or adrenoceptors). (washington.edu)
  • As we shall see later, subdivisions of each of these families of receptors are based on sensitivity to various agonist and antagonist drugs. (washington.edu)
  • Cholinergic receptors were originally divided and named on the basis of sensitivity to alkaloids that mimicked some, but not all, of the actions of ACh. (washington.edu)
  • Thus, cholinergic receptors are broadly classified as muscarinic (mAChR) or nicotinic (nAChR). (washington.edu)
  • Although these muscarinic receptors are not innervated by cholinergic nerve fibers, they are sensitive to circulating molecules. (washington.edu)
  • Cholinergic, receptors mediate the actions of acetylcholine (ACh). (washington.edu)
  • Pirenzepine is a relatively selective antagonist of M1 receptors. (washington.edu)
  • However, muscarinic receptors also exist on effectors cells, even in the absence of cholinergic innervation. (washington.edu)
