Cholinergic Antagonists
Scopolamine Hydrobromide
An alkaloid from SOLANACEAE, especially DATURA and SCOPOLIA. Scopolamine and its quaternary derivatives act as antimuscarinics like ATROPINE, but may have more central nervous system effects. Among the many uses are as an anesthetic premedication, in URINARY INCONTINENCE, in MOTION SICKNESS, as an antispasmodic, and as a mydriatic and cycloplegic.
Muscarinic Antagonists
Drugs that bind to but do not activate MUSCARINIC RECEPTORS, thereby blocking the actions of endogenous ACETYLCHOLINE or exogenous agonists. Muscarinic antagonists have widespread effects including actions on the iris and ciliary muscle of the eye, the heart and blood vessels, secretions of the respiratory tract, GI system, and salivary glands, GI motility, urinary bladder tone, and the central nervous system.
Parasympathomimetics
Drugs that mimic the effects of parasympathetic nervous system activity. Included here are drugs that directly stimulate muscarinic receptors and drugs that potentiate cholinergic activity, usually by slowing the breakdown of acetylcholine (CHOLINESTERASE INHIBITORS). Drugs that stimulate both sympathetic and parasympathetic postganglionic neurons (GANGLIONIC STIMULANTS) are not included here.
Atropine
Mecamylamine
Parasympatholytics
Quinuclidinyl Benzilate
Receptors, Cholinergic
Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.

Hormone Antagonists
Dopamine Antagonists
Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.
Excitatory Amino Acid Antagonists
Neurokinin-1 Receptor Antagonists
Histamine H2 Antagonists
Drugs that selectively bind to but do not activate histamine H2 receptors, thereby blocking the actions of histamine. Their clinically most important action is the inhibition of acid secretion in the treatment of gastrointestinal ulcers. Smooth muscle may also be affected. Some drugs in this class have strong effects in the central nervous system, but these actions are not well understood.
Interleukin 1 Receptor Antagonist Protein
GABA Antagonists
Histamine H1 Antagonists
Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood.

Receptors, N-Methyl-D-Aspartate
A class of ionotropic glutamate receptors characterized by affinity for N-methyl-D-aspartate. NMDA receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity.

Dizocilpine Maleate
A potent noncompetitive antagonist of the NMDA receptor (RECEPTORS, N-METHYL-D-ASPARTATE) used mainly as a research tool. The drug has been considered for the wide variety of neurodegenerative conditions or disorders in which NMDA receptors may play an important role. Its use has been primarily limited to animal and tissue experiments because of its psychotropic effects.

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.
