Antihistamines, among the most commonly prescribed drugs in the world, have evolved considerably since the first generation was introduced >50 years ago. The first generation antihistamines (e.g., chlorpheniramine, diphenhydramine, promethazine and hydroxyzine) are still widely available and in use today. These drugs have considerable sedative effects caused by their ability to cross the blood-brain barrier. The next generation of antihistamines to emerge in the market were devoid of these sedative effects; however, two (terfenadine and astemizole) have shown rare but lethal cardiotoxic side effects. The third generation antihistamines, metabolites of the earlier drugs, have demonstrated no cardiac effects of the parent drugs and are at least as potent. Many have exhibited superior pharmacokinetic and pharmacological profiles, including an improved onset of action and duration of effect. The clinical benefit of these newer oral antihistamines will clearly help improve the quality of life of patients with chronic allergies.

Eosinophils are well known to play essential roles in the development and maintenance of allergic diseases. However, the influence of histamine H1 receptor antagonists on eosinophil functions, especially chemokine production, are not well-defined. Therefore, in the present study, we examined the influence of histamine H1 receptor antagonist on chemokine production by eosinophils through the use of levocetirizine in vitro and in vivo. Eosinophils prepared from mice were stimulated with specific antigens in the presence of different concentrations of levocetirizine. After 24 h, regulated on activation normal T cell expressed and secreted (RANTES) and eotaxin levels in culture supernatants were measured by enzyme-linked immunosorbent assay (ELISA). Patients with Japanese cedar pollinosis were treated with 5 mg levocetirizine once a day for four weeks during the pollen season (February 2012 to April 2012). RANTES and eotaxin levels in nasal secretions were also examined by ELISA. The addition of levocetirizine to eosinophil cultures caused a dose-dependent decrease in the ability of cells to produce RANTES and eotaxin in response to antigen stimulation, and the minimum concentration that caused a significant decrease was 0.05 μM. Although cetirizine also exerted suppressive effects on the production of RANTES and eotaxin by eosinophils, the minimum concentration that caused significant suppression was 0.15 μM, which was three-times higher than that of levocetirizine. Oral administration of levocetirizine for four weeks also reduced RANTES and eotaxin levels in nasal secretions from patients with pollinosis, along with attenuation of clinical symptoms. The ability of levocetirizine to reduce RANTES and eotaxin levels may account, at least in part, for the clinical efficacy of the agent for allergic disorders, including allergic rhinitis.

The included studies did not report on all the outcomes that were pre-specified in the protocol for this review. Even though more effective than placebo, due to the high risk of bias of the included studies, the small number of studies and the overall small sample size, it is not possible to recommend hydroxyzine as a reliable first-line treatment in GAD.

We previously reported that streptozotocin-induced diabetic mice showed depressive-like behavior in the tail suspension test. It is well known that the central histaminergic system regulates many physiological functions including emotional behaviors. In this study, we examined the role of the central histaminergic system in the diabetes-induced depressive-like behavior in the mouse tail suspension test. The histamine contents in the hypothalamus were significantly higher in diabetic mice than in non-diabetic mice. The histamine H(1) receptor antagonist chlorpheniramine (1-10 mg/kg, s.c.) dose-dependently and significantly reduced the duration of immobility in both non-diabetic and diabetic mice. In contrast, the selective histamine H(1) receptor antagonists epinastine (0.03-0.3 microg/mouse, i.c.v.) and cetirizine (0.01-0.1 microg/mouse, i.c.v.) dose-dependently and significantly suppressed the duration of immobility in diabetic mice, but not in non-diabetic mice. Spontaneous locomotor activity was not affected by histamine H(1) receptor antagonists in either non-diabetic or diabetic mice. In addition, the number and affinity of histamine H(1) receptors in the frontal cortex were not affected by diabetes. In conclusion, we suggest that the altered neuronal system mediated by the activation of histamine H(1) receptors is involved, at least in part, in the depressive-like behavior seen in diabetic mice.

A 46-year-old woman with a history of severe allergies, including food allergies, and angioedema was evaluated at the emergency department (ED) for an acute episode of angioedema. Upon arrival at the ED, the patient had severe jaw tightness, facial numbness, uncontrollable cheek lifting, swollen eyes, and a swollen protruding tongue and was unable to catch her breath. Her dyspnea was apparent, and she was unable to talk and instead used hand and face gestures for affirmative and negative responses. The patient was treated with 0.3 mg epinephrine intramuscularly into the right thigh. After treatment, she had a temperature of 37 degrees C, a pulse of 90 beats/ min, a blood pressure value of 100/59 mm Hg, a respiratory rate of 16 breaths/min, and 100% oxygen saturation on room air. After stabilization, she reported that her allergies had been adequately controlled with ebastine 10 mg daily, montelukast 10 mg daily, and vitamins (unspecified). The patient reported that since she started montelukast one month prior, she experienced three similar episodes, the first occurring five days after starting the drug. She mentioned being diagnosed and adequately treated these three times in the ED for angioedema. The patient denied any changes in eating habits or in her medications except for starting montelukast. She was observed at the ED for an hour and then discharged after stabilization on hydroxyzine hydrochloride 25 mg orally daily and fexofenadine hydrochloride 180 mg orally daily. Montelukast was discontinued.

We chose five sedatives for premedication and investigated the effect of these drugs on the induction doses of propofol. One hundred patients were allocated into one of five groups of 20. These groups consisted of control group (C) given only atropine 0.5 mg i.m.; CL group (plus clonidine 0.15 mg orally); H group (plus hydroxyzine 25 mg i.m.); M group (plus midazolam 3 mg i.m.) and D group (plus diazepam 10 mg orally). The induction dose was measured using loss of count technique. Arterial pressure and heart rate were measured, before and after propofol induction as well as after intubation. We also calculated rate pressure products (RPP) at each point. The induction doses were significantly lower in M-group than those in C-group. On the other hand, in hemodynamic responses, RPP was unchanged in any groups after propofol induction and after the intubation. Both propofol and midazolam have been known to have a depressive effect on the central nervous system via GABA-A receptor-mediated inhibition, although the exact receptor for propofol is unknown. We thought, therefore, that when the interaction occurred, both midazolam and propofol had the same effect on the GABA-A receptor and increased chloride ion flux through the channels. Hydroxyzine and clonidine, however, do not share a common receptor or exert effect on the GABA-A receptor. We consider that this was one of the reasons why induction doses of both H and CL group could not decrease significantly. We concluded that midazolam 3 mg decreased propofol induction dose significantly. Both midazolam 3 mg and clonidine 0.15 mg decreased RPP before induction and hemodynamic responses to induction and intubation were stable.

The pharmacokinetics and pharmacodynamics of medications may differ between children and adults, necessitating different dose regimens for different age groups. Levocetirizine, the active enantiomer of cetirizine, is used in the treatment of allergic rhinitis and chronic urticaria in Europe. Its pharmacokinetics and pharmacodynamics have not yet been studied prospectively in school-age children.

Sixteen children, aged 2 to 5 years and ranked ASA 1, were included in this study assessing gastro-oesophageal reflux occurring under halothane anaesthesia, before and during, caudal anaesthesia. They were scheduled for surgery below the umbilicus lasting 1 to 5 h. After premedication with oral hydroxyzine (2 mg.kg-1) and intravenous atropine (10 micrograms.kg-1), induction was carried out with 3% halothane. A gastro-oesophageal pH probe was inserted via the nose after calibration at 37 degrees C. A neutral pH for the oesophageal electrode and an acid pH for the gastric one demonstrated the correct position of the probe. The pH was then registered every 4 s. The probe was left in situ until the patient left the recovery room. The caudal anaesthesia catheter was then inserted with the patient lying on his left side. Caudal anaesthesia was began with 2.5 mg.kg-1 of plain bupivacaine and 5 mg.kg-1 of plain lidocaine. When the patient was lying supine again, narcosis was maintained with 0.5% halothane and 50% nitrous oxide. A dose of 1.5 mg.kg-1 of bupivacaine was injected every 30 to 45 min. None of the children displayed any respiratory signs (coughing, dyspnoea, bronchospasm, cyanosis) during the combined anaesthetic. Two episodes of asymptomatic gastro-oesophageal reflux were revealed by this method, one lasting 7 minutes and occurring during insertion of the caudal catheter, and the other, lasting 4 minutes, during recovery. There were no pulmonary sequels. There was excellent respiratory and haemodynamic stability throughout. The two episodes seemed to have been triggered off by rapid displacement of the patient and too deep an anaesthetic.(ABSTRACT TRUNCATED AT 250 WORDS)

Hydroxyzine is an antihistaminic with sedative properties used in the control of anxiety and emesis. Peripheral blood hydroxyzine concentrations are compared to central blood and liver concentrations in 10 medical examiner cases. Specimens were initially screened for alcohol and simple volatiles by GC-FID headspace analysis, ELISA for drugs of abuse, and alkaline drugs by GC/MS. Hydroxyzine, when detected by the alkaline drug screen, was subsequently confirmed and quantified by a specific GC-NPD procedure. Data suggest that postmortem peripheral blood hydroxyzine concentrations may be considered therapeutic to at least 0.24 mg/L and corresponding liver concentrations to at least 4.9 mg/kg. Hydroxyzine concentrations ranged 0.07-3.0mg/L in peripheral blood, 0.04-3.8 mg/L in central blood, and 0.88-55 mg/kg in liver. Hydroxyzine central blood to peripheral blood ratios averaged 0.92±0.25 (±standard deviation; N=6). Liver to peripheral blood ratios, on the other hand, were higher and averaged 13.8±6.2 (±standard deviation; N=10). Given that a liver to peripheral blood ratio less than 5 is consistent with little to no postmortem redistribution while exceeding 20-30 is indicative of propensity for significant postmortem redistribution, these data suggest that hydroxyzine is prone to a moderate degree of postmortem redistribution.

The diagnosis of cutaneous drug eruption as non pigmenting fixed drug eruption related to cetirizine and hydroxyzine was retained. Allergy to both H1 antihistamines can be explained by the fact that they've got the same chemical node that is piperazine, and by the fact that cetirizine is the main metabolite of hydroxyzine. Oral test provocation was omitted because the patient had already reexposed himself to the drugs. To identify the drug responsible for fixed drug eruption, peroral provocation tests are the most valuable method, but carry the risk of a strong reaction. Some authors use patch tests, but their positivity is inconstant. Their interest in fixed drug eruption is undergoing assessment.

A total of 510 atopic children (mean +/- SEM age, 19.4 +/- 0.2 months) composed the intention-to-treat population. During the subsequent 18 months, 27.5% (70/255) of the children taking levocetirizine and 41.6% (106/255) of the children taking placebo experienced urticaria (P < .001). The mean +/- SEM number of urticaria episodes was 0.71 +/- 0.11 in those receiving levocetirizine and 1.71 +/- 0.25 in those receiving placebo (P < .001). The mean +/- SEM duration of urticaria episodes was 4.43 +/- 1.57 days in those receiving levocetirizine and 5.36 +/- 1.27 days in those receiving placebo (P < .001).

It has been reported that chiral dual system is able to improve the enantioseparation of enantiomers in many cases. Currently, the dual systems involved in CE chiral separation are mostly dual CDs systems, and the polysaccharides-based chiral dual system was reported in only one paper. To the best of our knowledge, the use of chondroitin sulfate C (CSC)-based dual system for enantiomeric separation has not been reported previously. Herein, four CSC-based chiral dual systems, namely CSC/glycogen, CSC/chondroitin sulfate A buy atarax (CSA), CSC/hydroxypropyl-β-CD (HP-β-CD), as well as CSC/β-CD (β-CD), were evaluated for the first time for their enantioseparation capability by CE in this paper. During the course of the work, the influences of chiral selector concentration and buffer pH values on enantioseparation in dual systems were systematically investigated. Under the optimized conditions, the dual system consisting of CSC and glycogen exhibited better separations toward nefopam, duloxetine, sulconazole, atenolol, laudanosine, and cetirizine enantiomers compared to the single CSC or glycogen system. The combination of CSC and HP-β-CD improved the separation of amlodipine and chlorphenamine enantiomers. However, no synergistic effect was observed in the CSC/CSA and CSC/β-CD systems.

Increased numbers of activated mast cells have been documented close to substance P ( buy atarax SP) containing nerve endings in the bladders of patients with interstitial cystitis (IC), a painful, sterile bladder disorder occurring primarily in females. Many of these patients also suffer from allergies, but common antihistamines do not help. In line with the fact that IC symptoms worsen under stress, we recently showed that bladder mast cells could be activated by the stable acetylcholine (Ach) analogue carbachol and by immobilization stress. Preliminary data from open label studies indicated that the heterocyclic histamine-1 receptor antagonist (H-1r alpha) hydroxyzine reduces IC symptoms. We, therefore, investigated whether hydroxyzine could inhibit carbachol-induced bladder mast cell activation.

The neutral form of hydroxyzine interacted mainly via hydrophobic interactions with the bilayer lipid core of the membrane, whereas for the cationic form both hydrophobic and electrostatic interactions were involved. Zwitterionic and anionic cetirizine were less lipophilic than its cation, buy atarax which behaved like the corresponding species of hydroxyzine. Zwitterionic cetirizine interacted more by weak electrostatic interactions with the polar headgroups of phospholipids than by hydrophobic interactions with the membrane interior. The lipophilicity of its anion reflected the balance of repulsive electrostatic interactions between the carboxylate and phosphate groups and the hydrophobic interactions with the lipid core.

This double-blind randomized crossover placebo-controlled study was designed to assess objectively the nasal antihistamine effect of cetirizine in patients with allergic rhinitis and control subjects. Nasal challenge was performed by nebulization of increasing doubling doses of histamine (0; 0.04 to 1.28 mg/nostril) in six patients with allergic rhinitis and six control subjects on cetirizine (2 x 10 mg daily for 3 days) or placebo. Sneezings were counted and nasal obstruction was assessed by subjective scoring and by objective measurement of nasal airway resistance by posterior rhinomanometry. Histamine induced sneezing and a dose-dependent increase in nasal airway resistance buy atarax and in perceived sensation of obstruction. Responses were greater in patients with allergic rhinitis compared with controls, although of borderline significance for nasal obstruction. Cetirizine totally abolished sneezing and significantly reduced increase in nasal airway resistance and perceived sensation of nasal obstruction both in normal and rhinitic subjects. Our results demonstrate by an objective measurement the nasal antihistamine effect of cetirizine. We propose this simple provocation test to assess the time-course of the effect of antihistamines and to compare the relative potency of related compounds.

To control the release rate and mask the bitter taste, cetirizine dihydrochloride (CedH) was entrapped within chitosan nanoparticles (CS-NPs) using an ionotropic gelation process, followed by microencapsulation to produce CS matrix microparticles using a spray-drying method. The aqueous colloidal CS-NPs dispersions with a drug encapsulation efficiency (EE) of <15%, were then spray dried to produce a powdered nanoparticles-in-microparticles system with an EE of >70%. The resultant spherical CS microparticles had a smooth surface, were free of organic solvent residue and showed a diameter range of 0.5~5 μm. The in vitro drug release properties of CedH encapsulated microparticles showed an initial burst effect during the first 2 h. Drug release from the matrix CS microparticles could be retarded by the crosslinking agent pentasodium tripolyphosphate or the wall material. The technique of 'ionotropic gelation' combined with 'spray-drying' could be applicable for preparation of CS nanoparticlesin-microparticles drug delivery buy atarax systems. CS-NPs based microparticles might provide a potential micro-carrier for oral administration of the freely water-soluble drug--CedH.

Histamine released from dermal mast cells plays a central role in the increased vascular permeability in acute urticaria, and administration of anti-histamines usually suppresses development of wheals. Acute idiopathic urticaria, particularly a severe case, occasionally presents with acute inflammatory reactions such as low-grade fever and leukocytosis and is resistant to anti-histamines. Considering the wide spectrum of proinflammatory cytokines and chemokines that can be released from activated mast cells, some of them might be involved in the pathogenesis of urticaria. We measured plasma levels of interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-alpha) in 16 cases of severe acute urticaria. None of them showed elevated plasma levels of IL-8 or TNF-alpha. Nine out of 16 acute urticaria patients showed elevated circulating IL-6 with concomitant increases in serum CRP levels. All such patients were resistant to conventional anti-histamine treatment and required systemic steroids for complete suppression of wheal development. After subsidence of the urticaria, their elevated IL-6 and CRP levels dropped to their Vasotec Dosage Iv normal ranges. In contrast, all but one patient without elevated circulating IL-6 was successfully treated with a H1 receptor antagonist, cetirizine. The data suggest involvement of IL-6 in the pathogenesis of severe acute urticaria that is resistant to anti-histamines.

This was a double blind, placebo-controlled, 4-way cross-over study in 12 healthy volunteer subjects of the acute effects of three drugs each of which are used in the clinic to treat some forms of anxiety: propranolol 40 mg, hydroxyzine 25 mg, flupentixol 0.5 mg and placebo. Each test session consisted of inhalation of air for 20 min, 10-min rest, inhalation of CO2 7.5% for 20 min, 10-min rest, followed by a single vital capacity inhalation of 35% CO2. The CO2 7.5% was administered at peak drug effect. Subjective effects were measured using Visual Analogue Vasotec Generic Drug Scales (VAS), the Panic Symptom Inventory and the Generalised Anxiety Disorder Assessment inventory. Twelve subjects participated (eight men), with a mean age of 25.9 years. The expected subjective effects of CO2 were seen and these were significantly different from effects of peak air. However, there were no statistically significant differences between the drugs or between drugs and placebo, indeed there was a trend for some VAS anxiety scores to be higher than placebo in the drug groups. There were some significant differences in cardiovascular responses to CO2, with propranolol significantly decreasing heart rate and flupentixol increasing blood pressure when compared with placebo. The lack of subjective anxiolytic actions of the three drugs contrasts with our previous findings with acute benzodiazepines and chronic selective serotonin reuptake inhibitor administration. It may be that prolonged treatment with these agents would be required to show anxiolytic effects, although it may also be that their efficacy is insufficient to be demonstrated in this model. The lack of anxiolytic actions of propranolol, despite a significant reduction in heart rate, is a further support for a central action of CO2 to produce anxiety.

Allergic rhinitis (AR) affects a large percentage of paediatric patients. With the wide array of available agents, it has become a challenge to choose the most appropriate treatment for patients. Second-generation antihistamines have become increasingly popular because of their comparable efficacy and lower incidence of adverse effects relative to their first-generation counterparts, and the safety and efficacy of this drug class are established in the adult population. Data on the use of the second-generation antihistamines oral cetirizine, levocetirizine, loratadine, desloratadine and fexofenadine, and the leukotriene receptor antagonist montelukast as well as azelastine nasal spray in infants and children are evaluated in this review. These agents have been found to be relatively safe and effective in reducing symptoms associated with AR in children. Alternative dosage forms such as liquids or oral disintegrating tablets are available for most agents, allowing ease of administration to most young children and infants; however, limited data are available regarding use in infants for most agents, except desloratadine, cetirizine and montelukast. Unlike their predecessors, such as astemizole and terfenadine, the newer second-generation antihistamines and montelukast appear to be well tolerated, with absence of cardiotoxicities. Comparative studies are limited to cetirizine versus ketotifen Deltasone Generic Name , oxatomide and/or montelukast. Although second-generation antihistamines and montelukast are deemed relatively safe for use in paediatric patients, there are some noteworthy drug interactions to consider when selecting an agent. Given the wide variety of available agents for treatment of AR in paediatric patients, the safety and efficacy data available for specific age groups, type of AR, dosage form availability and cost should be considered when selecting treatment for AR in infants and children.

Allergic rhinitis (AR) and acute urticaria are common childhood maladies. Hytrin Tab Typically, the firstline treatment options for both include non-sedating antihistamines. First-generation antihistamines, such as diphenhydramine and hydroxyzine, although useful, cause sedation. Desloratadine, an oral non-sedating antihistamine, has been shown in multiple studies to be safe and effective in relieving the symptoms of AR and chronic idiopathic urticaria (CIU) in adults and adolescents.

We performed a placebo-controlled study, with 120 persistent, moderate to severe allergic rhinitis patients randomly selected to receive the different treatments for 4 weeks: no treatment, 10 mg of cetirizine once per day, 20 mg of zafirlukast once per day Sinequan 50 Mg , 20 mg of cafirlukast twice per day, a combination of 20 mg of zafirlukast and 10 mg of cetirizine once per day, or a combination of 20 mg of zafirlukast twice per day and 10 mg cetirizine once per day. The nasal secretion nitric oxide (NO) concentration, nasal symptom score, and nasal resistance were measured before and after treatment.

The ability of cetirizine, a novel antihistamine agent, to inhibit the in vivo activation of human eosinophils, neutrophils and monocytes has been investigated using C3b- and IgG-dependent rosette formation, cytotoxicity against opsonised parasitic larvae and adherence to plasma-coated glass (PCG). The drug inhibited platelet Buspar Positive Reviews -activating factor (PAF)-induced enhancement of eosinophil and neutrophil IgG (Fc) and complement (C3b) rosettes with an IC50 of 2 x 10(-5) M. There was also comparable inhibition of PAF-dependent enhancement of eosinophil cytotoxicity (for complement-coated schistosomula of Schistosoma mansoni). Cetirizine inhibited PAF-induced eosinophil, but not neutrophil, hyperadherence to PCG. These data support the view that cetirizine may exert some of its anti-allergic effects by inhibiting the activation of human granulocytes and that it may also selectively inhibit PAF-induced eosinophil hyperadherence.

We evaluated the efficacy of midazolam-famotidine suppository (M-F suppository) for premedication in children. After obtaining informed parental consent, we studied children aged 5m-7y, ASA I status, scheduled for minor elective surgery. The suppository group (n = 26) was given suppository of both midazolam 0.5 mg.kg-1 and famotidine 2 mg.kg-1, and the intramuscular injection group (n = 19) was given hydroxyzine 1 mg.kg-1. In the suppository group, gastric pH (3.90 +/- 0.34) was significantly higher, and gastric volume (1.88 +/- 0.54 ml) was significantly less than in the intramuscular injection group (1.82 +/- 0.15, 8.42 +/- 1.76 ml). The M-F suppository may offer similar sedative effect as an intramuscular injection of hydroxyzine. We concluded that the M-F suppository is an effective premedicant for pediatric patients.

Skin tests are the most useful single modality for demonstrating an IgE-mediated mechanism underlying clinical symptoms. Skin reactivity to an allergen depends on person's exposure and genetic factors influencing the IgE response. However, the reproducibility of allergy skin tests has been shown to be variable depending, among other things, on the allergen extract employed and the kind of technique used. These variations have led to controversy regarding clinical relevancy of allergy skin testing [1-7]. We examined the relationship of skin-prick test and serum allergen-specific IgE in pollen susceptible adult persons. We estimated changes in the immediate skin reactivity to pollen-allergens by testing patients on more than one occasion: a) during and out of pollen season; b) before and after completing specific immunotherapy, and c) who had been tested with diverse concentrations of the same pollen-allergen. We correlated the degree of skin reactivity at the initial and subsequent testings with the aim of estimate diagnostic relevancy of such performed allergy skin testings.
