The drugs proposed are considered according to their site of action. Synthetic anti-cortisol drugs (Op'DDD in particular and aminoglutethimide) appear to be the drugs of choice at present. They act on the adrenals, but research is now being carried out on drugs which act on ACTH secretion, E.g; cyproheptadine and bromocriptine.

A 9-month-old female Labrador retriever was evaluated after ingestion of a 5-HTP supplement. Signs of agitation developed within 1 h of ingestion, and emesis was attempted by the owner with  3% hydrogen peroxide (H2O2) orally. On presentation, the dog was obtunded, bilaterally mydriatic and salivating. Physical exam revealed tachypnea, tachycardia, hyperthermia, and hypertension. Eighteen hours post presentation, the dog developed melena, hematemesis, and pigmenturia. A hemogram revealed mild anemia with evidence of oxidative erythrocyte damage (eccentrocytes, Heinz bodies, and siderocytes). A chemistry panel revealed markedly elevated creatine kinase and hyperbilirubinemia, supporting hemolytic anemia. A urinalysis revealed pigmenturia. Hemolytic anemia was presumed to be caused by oxidative damage secondary to gastrointestinal ulceration and circulatory embolism of H2O2. Treatment included fluid therapy, a mannitol constant rate infusion, antiemetics, gastroprotectants, and cyproheptadine as a serotonin antagonist. The patient responded well to treatment and was discharged within 48 h of presentation.

1 The intravenous injection of pethidine in rabbits pretreated with furazolidone administered orally but not systemically resulted in severe interaction and fatal hyperpyrexia. 2 Treatment with rho-chlorophenylalanine, chloropromazine of cyproheptadine protected the rabbits against the furazolidone-pethidine interaction, while alpha-methyl-rho-tyrosine was ineffective. 3 5-Hydroxytryptophan produced a fatal hyperpyrexia in furazolidone pretreated rabbits. 4 Pretreatment of rabbits with 1,1,1-trichloro-2, 2-bis(rho-chlorophenyl)ethane (DDT) accelerated and enhanced the furazolidone-pethidine interaction, while oxytetracycline pretreatment completely prevented the interaction. 5 It is concluded that furazolidone-pethidine interaction might depend mainly on potentiation of the effects of 5-hydroxytryptamine in the CNS and that the transformation of furazolidone into an active monoamine oxidase inhibitor metabolite might occur mainly in the gut microflora in the gut lumen.

Pituitary adenomas may produce local endocrine and neurological effects, as well as systemic metabolic complications due to hormonal hypersecretion. Medical therapy with pharmacological agents has been developed and is based on the neurotransmitter regulation of normal pituitary hormonal secretion. 189 patients with secretory pituitary adenomas underwent medical therapy for the hypersecretory state. 156 of these were prolactin-secreting adenomas, 16 of which were in males. The response of bromocriptine was almost universal with lowering of serum prolactin and reversal of the clinical symptoms, as well as tumor shrinkage of most large adenomas with suprasellar extension. 23 patients with acromegaly were treated with bromocriptine, with 11 noting clinical improvement, and decreased tumor size in two. Five patients with Cushing's disease were treated with cyproheptadine, with only one showing a biochemical and clinical improvement. Two patients with Nelson's syndrome each had progressive tumor growth stabilized with cyproheptadine and bromocriptine in one, and sodium valproate in the other. There appears to be a role for medical therapy in the majority of prolactin-secreting pituitary tumors, some growth hormone secreting pituitary tumors, and selected adrenocorticotropin secreting-pituitary tumors.

Less than Glu-His-Pro-OH or 'acid' TRH, until now considered to be an inactive metabolite of TRH, induces in rats when administered intracerebroventricularly (i.c.v.), stereotyped behavior and, from 12.5 micrograms, wet-dog shakes (WDS). WDS induced by 200 micrograms less than Glu-His-Pro-OH are antagonized by apomorphine, haloperidol and cyproheptadine while phentolamine and naloxone are without effect. For this action 'acid' TRH appears as effective as TRH itself and might have the same mechanism.

Various drugs acting on brain serotonin or catecholamines were administered concurrently with morphine during the development of dependence or before naloxone-precipitated withdrawal syndrome. Of the various drugs only cyproheptadine, a serotonin antagonist, and piribedil, a dopamine agonist, reduced the frequency of jumping (but not of diarrhea or ptosis) when administered with morphine during development of dependence. When administered before naloxone, d-fenfluramine, a serotonin releaser, markedly reduced jumping, but not diarrhea and ptosis, and clonidine blocked these latter signs without affecting the frequency of jumping. Of the other drugs examined only phenoxybenzamine reduced diarrhea in morphine-abstinent rats. It is suggested that serotonin is involved in the mechanisms which lead to compulsive jumping during naloxone-precipitated withdrawal, whereas adrenergic sites on which clonidine acts are mainly involved in the expression of signs, such as ptosis and diarrhea. No clear evidence was obtained of a role for dopamine in the withdrawal signs studied.

Head-twitches have been regarded as an experimental model of hallucination, and we have recently observed that p-hydroxyamphetamine (p-OHA) markedly induced head-twitches in mice. The present work was undertaken to study possible participation of a serotonergic system in the mechanism of head-twitches induced by p-OHA. Head-twitches induced by p-OHA continued for 20-80 min, and the peak time of this effect was approximately 30-40 min after the administration. The i.c.v. administration of p-OHA (20, 40, 80 and 160 micrograms/mouse) produced characteristic head-twitches in a dose-dependent manner. Simultaneous injection of serotonin (10 micrograms/mouse, i.c.v.) and p-OHA caused a 2-2.5-fold increase in the number of head-twitches compared with non-serotonin controls. Pretreatment with p-chlorophenylalanine (200 mg/kg, i.p. and 500 micrograms/mouse, i.c.v.), in contrast, reduced head-twitches as did the pretreatment with cyproheptadine or dimethothiazine. These results suggest that p-OHA-induced head-twitches may involve the central serotonergic system which may exert an excitatory effect on head-twitches.

Arachidonic Acid (AA) injected into a hindpaw of Lewis rats produces high levels of tissue myeloperoxidase (MPO), a biochemical marker for PMN leukocytes. Treatment with a corticosteroid (prednisolone) or dual 5-LO/CO inhibitors of AA metabolism (phenidone, SKF 86002) produced dose-related inhibition of AA-induced elevations in paw tissue MPO levels. In contrast, administration of high pharmacologic doses of selective cyclooxygenase inhibitors (indomethacin, ibuprofen, naproxen), anti-histamine/serotonin agents (cyproheptadine, chlorpheniramine) or an anti-arthritic gold compound (auranofin) produced only slight or moderate effects. Thus, AA-induced hindpaw inflammation is a useful method for determining pharmacologic effects of 5-LO/CO inhibitors on PMN leukocyte infiltration in vivo.

Neurotransmitters and neuropeptides interact in several ways. We studied a new type of interaction: the effect of neurotransmitters on the saturable system that transports Tyr-MIF-1 and the enkephalins out of the central nervous system (CNS). The neurotransmitters were introduced into the lateral ventricle of the brain with radioiodinated peptide, using an established method previously shown to accurately quantify the amount of peptide being transported from the CNS to the blood. Serotonin inhibited transport, histamine stimulated transport, and dopamine, acetylcholine, epinephrine, GABA, kainic acid, cAMP and cGMP were without effect. Cyproheptadine, a serotonin antagonist, stimulated transport. Of several psychotropic agents tested, only tranylcypromine had a statistically significant effect and stimulated transport. Of the serotonin receptor specific agents tested, those with 5HT1 activity most consistently affected transport. We conclude that serotonin, and perhaps histamine, are important modulators of the system that transports Tyr-MIF-1 and the enkephalins out of the CNS.

Biological activities of C3 beta c, which is a C-terminal fragment of the beta-chain of rat complement C3, have been studied by in vivo and in vitro experiments. C3 beta c was purified as a novel neutrophil chemoattractant from the exudate of the chronic phase of rat carrageenin-induced inflammation. The purified C3 beta c induced neutrophil chemotaxis in vivo when C3 beta c was injected into the preformed air-pouch on the back of rats. C3 beta c transiently increased the intracellular free Ca2+ concentration of neutrophils and enhanced the adhesion of neutrophils to fibrinogen in vitro, suggesting that C3 beta c has the ability to express an adhesion molecule of rat neutrophils. In addition, C3 beta c at low concentrations (10(-10)-10(-11) M) stimulated rat macrophages to produce cytokine-induced neutrophil chemoattractant-2, a member of the interleukin-8 family. Furthermore, C3 beta c enhanced vascular permeability in vivo, which is suppressed by cyproheptadine, suggesting that C3 beta c may have the characteristics of an anaphylatoxin. Our results suggest that C3 beta c contributes to oedema formation and neutrophil accumulation at inflammatory sites in rats.

Levocetirizine (5 mg), loratadine (10 mg), or placebo was taken orally 4 h before the intradermal injection of histamine (20 microl, 100 microM) or the control vehicle into the forearm skin of healthy volunteers. Flare areas were assessed by scanning laser Doppler imaging before and at 30-s intervals for a period of 9 min. Wheal areas were measured by planimetry at 10 min. Itch was scored every 30 s with a visual analogue scale.

Gas-liquid chromatographic and mass, nuclear magnetic resonance, and infrared spectrometric techniques were utilized to identify some of the metabolites of cyproheptadine in the urine of human subjects who had ingested radiolabeled drug. Aromatic ring hydroxylation (followed by glucuronide conjugation), N-demethylation, and heterocyclic ring oxidation were shown to occur in man. The principal metabolite, however, was identified tentatively as a quaternary ammonium, glucuronide-like conjugate of cyproheptadine. No evidence was found for metabolic changes at the tricyclic ethylene bridge in this species.

The basophil activation test (BAT) is a widely validated and reliable tool especially for the diagnosis of hymenoptera venom allergy. Nevertheless, several pitfalls have to be considered and outcomes may differ because of diverse in-house protocols and commercially available kits. We aimed to identify the factors that may influence results of the CD63-based BAT.

Eighteen healthy young subjects of both sexes took part in a crossover, randomised, double-blind, placebo-controlled study. Treatments tested were: RU 10, 20, 40 and 80 mg and hydroxyzine 25 mg, as a positive standard. Before and several times after drug intake, peripheral anti-H1 activity was appraised by the skin reactivity to intradermal injection of histamine. CNS effects were also obtained by objective tests of psychomotor performance and subjective mood scales.

1. The inflammatory response induced by poly-L-arginine in the rat hind-paw was studied both by measuring paw oedema and histologically. 2. The paw volume was measured with a hydroplethysmometer at 0.5, 1, 2, 4, 6 and 18 h after the subplantar injection of the polycation. Protein extravasation was evaluated with Evans' blue and the histology studied by light microscopy. 3. Poly-L-arginine (12, 24, 43 and 115kD) caused dose- and molecular weight-dependent oedema which had a rapid onset and long duration. Evans' blue extravasation paralleled the oedema induced by poly-L-arginine. Microscopic examination of the paws at early stages of oedema formation showed exuberant liquid exudate with no inflammatory cells. After 18 h, a cellular infiltrate was present, consisting mainly of mononuclear cells. 4. Indomethacin, dexamethasone, BW755c or the PAF-antagonist WEB 2086 caused no significant inhibition of the poly-L-arginine-induced oedema. Cyproheptadine had inhibitory effects only on the early stages of the polycation-induced oedema. Similar results were observed with rats depleted of histamine and 5-hydroxytryptamine. 5. Heparin, a polyanion, injected in the rat paw caused a marked inhibition of the polycation-induced oedema. NG-monomethyl-L-arginine (LNMMA), an inhibitor of EDRF synthesis, injected locally also produced a marked inhibition, but this inhibition was reversed by iloprost. 6. These results suggest that the oedema induced by polycations was due to their cationic charge. The inhibitory effect of LNMMA is probably due to a decrease in vascular flow rather than a decrease in vascular permeability.

Cytotoxic properties of plant extracts and drugs being developed for cancer treatment are usually evaluated by a variety of in vivo and in vitro tests carried out in animal or plant based models. In the present study we have evaluated the possibility of using the germinating mung beans (Vigna radiata), for rapid and inexpensive screening of drugs exhibiting cytotoxic properties. Mung beans were allowed to germinate either in tap water or in different drug solutions, and parameters like percent germination, increase in radicle length, change in seedling weight and mitotic index of apical root meristems were determined at two time intervals coinciding with the time at which the radicle length in control group was 1.0 to 1.5 cm (time 0, T0) and 48 h later (T48). Methanol extract of Calotropis procera latex as well as drugs like podophyllotoxin, cyclophosphamide, cyproheptadine and aspirin produced a dose-dependent inhibitory effect on seed germination, seed weight gain, radicle growth and mitotic index in the radicle meristems. The inhibitory effect of some of the drugs tested was associated with reduction in water imbibition. Some of the drugs at higher concentrations allowed seed germination to take place but produced radicle decay and seedling weight loss. Our study shows that germinating V radiata beans could be used as a convenient model for the preliminary screening of drugs exhibiting cytotoxic properties.

It was concluded that four common treatment modalities could effectively release symptom scores, but decrease of airway inflammation as determined by decrease of eNO might be only achieved by nasal budesonide and montelukast, but not nasal sodium cromoglycate and loratadine. Children with perennial allergic rhinitis with high eNO levels may require oral montelukast or nasal budesonide treatment to prevent airway hyperresponsiveness.

There was no significant overall diurnal variation of basophil numbers in healthy controls or chronic urticaria patients. Mean (SE) manually counted basophil were higher in healthy controls than chronic urticaria (43.4/ microL (2.1) vs. 4.4 (0.8), P < 0.001). Basophil counts were reduced in healthy controls on steroids (19.2 (1.9), P < 0.001) but increased in chronic urticaria (8.9 (1.9), P < 0.001). Loratadine did not influence them. UAS fell on treatment (3.3 (0.4) baseline, 1.4 (0.5) on loratadine and 0.5 (0.2) on prednisolone with loratadine, P < 0.001). There was a negative linear correlation between basophil numbers and UAS in untreated chronic urticaria patients (P = 0.001, Spearman rank correlation). Manual and automated basophil counts showed poor agreement. Lymphocyte numbers were lower in chronic urticaria than healthy controls. Neutrophils increased whereas lymphocytes and eosinophils decreased in all subjects on prednisolone. They were unaffected by loratadine.

The central serotonergic system was manipulated using a serotonin receptor antagonist (cyproheptadine), electrolytic lesioning of the raphe nuclei and neurochemical destruction of the serotonergic terminals in the hypothalamus. The effects of these interventions on ether-induced ACTH secretion were studied in adrenalectomized rats. Serotonin, norepinephrine and dopamine concentrations were measured in the medial basal hypothalamus (MBH) or in individual nuclei of the hypothalamus and of certain midbrain regions. Cyproheptadine pretreatment inhibited ether-induced ACTH hypersecretion in adrenalectomized animals. Neither buy periactin the electrolytic lesions of the midbrain raphe nuclei, nor the neurotoxic destruction of the hypothalamic serotonergic terminals (by intraventricular administration of 5,6-dihydroxytryptamine) caused any alteration of stimulated ACTH secretion after ether inhalation and/or long-term corticoid deficiency. These results suggest a lack of correlation between the activity of the central serotonergic system and the ACTH releasing effect of ether-stress in adrenalectomized rats.

Cyanoguanidine derivatives of loratadine (3a-i) were synthesized and screened for antitumor and anti-inflammatory activity. The most promising compound 3c (R=n-C(8)H(17)) possessed at least twofold higher in vitro cytotoxicity than 5-fluorouracil against mammary (MCF-7 and MDA-MB 231) as well as colon (HT-29) carcinoma cells. The mode of action, however, is so far unclear. The buy periactin participation of the COX-1/2 enzymes on the cytotoxicity, however, is very unlikely. Nevertheless all compounds showed stronger in vivo anti-inflammatory activity than ibuprofen in the xylene-induced ear swelling assay in mice.

After bilateral adrenalectomy in adult male rats a triphasic change occurs in the plasma concentration of radioimmunoassayable ACTH. Plasma ACTH is markedly elevated at 2 h, returns almost to normal at 20 h, and is again markedly elevated 92 h after adrenalectomy. We have examined brain serotonin (5HT) turnover during this period using two nonsteady state methods: accumulation of 5HT after monoamine oxidase inhibition with pargyline and decline of 5-hydroxyindoleacetic acid (5HIAA) after pargyline. Both endpoints demonstrated decreases in hypothalamic and brain stem 5HT turnover 2 and 92 h after adrenalectomy, but normal 5HT turnover 20 h after adrenalectomy. Thus, we demonstrated inverse relationships between 5HT turnover in both the hypothalamus and brain stem and the plasma ACTH concentration throughout the period of triphasic change after adrenalectomy. The adrenalectomy-induced increases in plasma ACTH and decreases in brain 5HT turnover both 2 and 92 h after adrenalectomy are inhibited by treatment with small doses of corticosterone. The data strongly suggest that the activity of some brain 5HT neurons changes after adrenalectomy in a triphasic pattern and, further, that these changes are related in part to glucocorticoid withdrawal. 5HT receptor antagonists blunted corticosterone inhibition of the adrenalectomy-induced decreases in brain 5HT buy periactin turnover, providing further evidence for an interaction between glucocorticoids and brain 5HT neurons. The data are consistent with a role of brain 5HT neurons in the adrenalectomy-induced triphasic changes in ACTH secretion.

A series of cyproheptadine related compounds was synthesized and tested pharmacologically. In comparison with cyproheptadine, these compounds do not have a central ring and some contain groups other than N-methyl. Synthesis was carried out with low-valent titanium to generate the exocyclic double bond. The serotoninergic activity of the compounds was determined by standard determination of pA2 (-log of the motor concentration of antagonist required to maintain a constant response when concentration of agonist is doubled) for the inhibition of serotonin-induced contractions in rat stomach fundus. Two of the nitrogen-containing compounds were active, but their activities were lower than that of cyproheptadine. Structure-activity relationships were studied by Mulliken net charges, molecular electrostatic potentials, and conformational analysis; activities are better correlated with electrostatic potentials than with net charges. The decrease in potency of the open cyproheptadine analogues may be due to "dilution" of the active conformer as the result of their conformational buy periactin flexibility.

Serum prolactin level (SPL) of anesthetized rats was measured in response to electroconvulsive shock (ECS). This measurement served as an indicator of dopaminergic and serotonergic activity. Such neurotransmitter activity was modulated by pretreatment with cyproheptadine, parachlorophenylalanine (PCPA), pimozide, bromocriptine or L-dopa. A statistically significant lowered SPL was found in rats given ECS plus antiserotonergic agents, in comparison with animals receiving antiserotonergic agent or ECS alone. When ECS was administered to rats pretreated with the dopaminergic blocker, pimozide, there was a significant decrease in SPL, compared with animals receiving pimozide alone. When the dopaminergic system was stimulated by dopamine agonists, there was no elevation of SPL in response to ECS. Thus, there may be a balance between serotonergic and dopaminergic systems. The agents used buy periactin in the experiment may upset this balance and produce a change in prolactin response to a given ECT stimulus.

Eyestalk-intact, but not de-eyestalked, crabs (Cancer antennarius) given five injections of 5-hydroxytryptamine (5HT, 750 micrograms per injection) in 48 hr showed significant reductions in hemolymph ecdysteroid titers within the first 12 hr which continued through Hour 72; the effect was reversible (Hours 72-144). The 5HT synthesis inhibitor p-chlorophenylalanine (PCPA; 60 micrograms) or the 5HT receptor antagonist cyproheptadine (CPH; 100 micrograms) caused significant rises in serum ecdysteroids in intact, but not in de-eyestalked, crabs; with buy periactin four injections over 48 hr, a rise was evident at 12 hr, continued through 72 hr, and returned to control levels within 4 days post-treatment. Stress due to handling depressed ecdysteroid levels, an effect that was reversed by PCPA and CPH; values in the treated groups returned to prestress levels within 24 hr and were significantly greater than prestress levels within 48 hr. 5HT treatment did not further decrease stress-reduced ecdysteroid titers. Normal behaviors are described in posturing and in defensive responses to stress; these were changed in both intact and de-eyestalked crabs by 5HT treatment (but not by PCPA or CPH). These findings support the hypothesis that release of molt-inhibiting hormone (MIH) from crab eyestalks is mediated by 5HT and suggest that stress induces 5HT-mediated MIH release.

Of 593 patients randomized to treatment, 592 were included in efficacy analysis. Acrivastine-pseudoephedrine and loratadine-pseudoephedrine demonstrated a mean onset-of-action by 45 and 30 minutes respectively for total symptom and rhinitis symptom scores for the five sites. Onset-of-action for nasal congestion scores was 45 minutes for both medications. Sites having higher pollen exposure (>100 pollen grains over 6 hours) demonstrated a difference between the antihistamine combinations: acrivastine-pseudoephedrine had an onset of action at 45 minutes for total symptom and rhinitis symptom scores, and 15 minutes for nasal congestion scores whereas loratadine-pseudoephedrine had onset-of-action for nasal congestion score of 105 minutes but failed to reach significance at buy periactin any timepoint for total symptom and rhinitis symptom scores.

The induction of lower lip retraction (LLR) by serotonergic (5HT) compounds and antagonism of LLR by compounds acting via a variety of receptor systems was investigated. LLR could be induced by subcutaneous injection of 8-hydroxy-2-(di-n-propylamino)-tetralin (8-OH-DPAT), buspirone, ipsapirone or RU 24969. Inactive were the putative 5HT1B,1C agonist 1-(3'chlorophenyl)-piperazine (mCCP), the 5HT2,1C agonist (dl)-1-(2,5 dimethoxy-4-iodophenyl)-2-aminopropane (DOI), the 5HT reuptake inhibitors citalopram and paroxetine and the 5HT-releasing compounds parachloroamphetamine (PCA) and fenfluramine. 5-Methoxy-N,N-dimethyltryptamine (5-MeODMT) induced lower lip retraction after pretreatment with metergoline, cyproheptadine or ritanserin but not by itself. 8-OH-DPAT-induced LLR could be antagonised by the direct and indirect 5HT agonists mCPP, DOI, 5- buy periactin MeODMT, PCA, fenfluramine and high doses of paroxetine, but not by the 5HT antagonists metergoline, methysergide, mesulergine, GR38032F, xylamidine or pirenperone. The dopamine agonists apomorphine and pergolide antagonised 8-OH-DPAT-induced LLR, whereas SKF 38393 was weakly active. No significant antagonism was found with the dopamine antagonists haloperidol and spiperone, the alpha 2 agonist clonidine and the alpha 1 antagonist prazosin and the alpha 2 antagonist idazoxan. Also inactive were the antihistaminic mepyramine, the anticholinergic atropine, the opiate antagonist naloxone and the anxiolytic chlordiazepoxide. The results suggest that, in vivo, functional interactions take place between the various 5HT receptors. The hypothesis that lower lip retraction is induced by compounds directly and selectively stimulating 5HT1A receptors is discussed.

The protective effects of two antihistamines and two anti-allergic drugs against anaphylactic paw edema were studied in immunized animals that had or had not received a booster injection of antigen. The injection of 1 or 10 micrograms/paw ovalbumin induced acute paw edema of similar intensity in both groups. The antihistamine meclizine and the mixed anti histamine/anti-5-HT antagonist cyproheptadine reduced the anaphylactic reaction by 55 and 84% respectively, in non-boosted animals and were less effective against edema induced by 1 microgram antigen in boosted animals buy periactin . The effectiveness of these drugs was also reduced when boosted mice were challenged with 10 micrograms antigen, where meclizine and cyproheptadine inhibited edema by 31 and 59%, respectively. The anti-allergic compounds ketotifen and azelastine, although effective against allergic inflammation in non-boosted mice, had a reduced or no effect in boosted mice. Our results suggest that allergic edema is less sensitive to antihistamine and anti-allergic drugs in boosted mice, which may be accounted for by an increased role of other mediators.

Intrathecal baclofen withdrawal syndrome is a known complication of intrathecal baclofen pumps. Its origin is postulated as an independent form of a serotonergic syndrome occurring from loss of gamma-aminobutyric acid B receptor-mediated inhibition of serotonin. Prodromal symptoms include pruritus, a return of deep tendon reflexes, and increased spastic hypertonia. Previous reports have documented use of cyproheptadine in treatment of this syndrome in adults with positive results. We present the case of a 14-yr-old child with cerebral palsy who developed pruritus and worsening spastic hypertonia 18 mos after pump implantation. She had been previously treated with 520 microg/day of intrathecal baclofen. Progression of her symptoms was successfully arrested by the administration of both oral and intrathecal baclofen and 6 mg of oral cyproheptadine every 6 hrs for 1 day. We postulate that cyproheptadine should be considered a valuable adjuvant therapy for buy periactin treatment of suspected intrathecal baclofen withdrawal syndrome.

The unexpected observation of a hyperglycemic effect of some tricycle-based delta opioid receptor (DOR) agonists led to a series of studies to better understand the finding. Single administration of two novel tricyclic DOR agonists dose dependently elevated rat plasma glucose levels; 4-week toxicology studies confirmed the hyperglycemic finding and further revealed pancreatic β-cell hypertrophy, including vacuole formation, as well as bone dysplasia and Harderian gland degeneration with regeneration. Similar diabetogenic effects were observed in dog. A review of the literature on the antiserotonergic and antihistaminergic drug cyproheptadine (CPH) and its metabolites revealed shared structural features as well as similar hyperglycemic effects to the present series of DOR agonists. To further evaluate these effects, we established an assay measuring insulin levels in the rat pancreatic β-cell-derived RINm5F cell line, extensively used to study CPH and its metabolites. Like CPH, the initial DOR agonists studied reduced RINm5F cell insulin levels in a concentration-dependent manner. Importantly, compound DOR potency did not correlate with the insulin-reducing potency. Furthermore, the RINm5F cell insulin results correlated with the diabetogenic effect of the compounds in a 5-day mouse study. The RINm5F cell insulin assay enabled the identification of aryl-aryl-amine DOR agonists that lacked an insulin-reducing effect and did not elevate blood glucose in repeated dosing studies conducted over a suprapharmacologic dose range. Thus, not only did the buy periactin RINm5F cell assay open a path for the further discovery of DOR agonists lacking diabetogenic potential but also it established a reliable, economical, and high-throughput screen for such potential, regardless of chemotype or target pharmacology. The present findings also suggest a mechanistic link between the toxicity observed here and that underlying Wolcott-Rallison Syndrome.

Onset of action for relief of allergic rhinitis symptoms is of clinical significance to both the physician and the patient. Using either subjective or objective methods, the onset of action after buy periactin a single, oral dose of an antihistamine can be measured. Multicenter studies, outdoor studies, and pollen challenge systems have been used to measure the onset of action. A literature search from 1985 to May 2002 was performed. All published, randomized, placebo-controlled clinical studies pertaining to the onset of action for relief of allergic rhinitis symptoms after a single, oral dose of a second-generation antihistamine (not combined with a decongestant) including cetirizine, desloratadine, fexofenadine, and loratadine, were reviewed. The onset of action for cetirizine ranged from 59 minutes to 2 hours and 6 minutes and for loratadine onset of action ranged from 1 hour and 42 minutes to none identified during the duration of the study. Cetirizine had a shorter onset of action than loratadine for all comparisons. Fexofenadine had an onset of action within 60 minutes. The literature search did not reveal any published onset of action studies for desloratadine. The onset of action for a given second-generation antihistamine depends on how it is defined and subsequently measured.

The effects of viloxazine on the flexor reflex of the hind limb of the spinal rat and the blood pressure in the pithed rat were studied. Viloxazine (1--16 mg/kg) stimulated the hind limb flexor reflex in the dose-dependent manner. This effect of viloxazine was inhibited by serotonin receptor blockers, cyproheptadine, danitracen and metergoline, and by serotonin uptake blocking agents imipramine and clomipramine. H22/54, an inhibitor of serotonin synthesis, was much less active in this respect. Desipramine, a noradrenaline uptake inhibitor, had no effect on the stimulatory action of viloxazine. Viloxazine (similarly as serotonin) elevated blood buy periactin pressure in the pithed rat. This action of viloxazine was abolished by cyproheptadine but potentiated by pargyline, an inhibitor of MAO. It is suggested that viloxazine may facilitate the serotonergic transmission in the central nervous system.

Electrical stimulation (2 Hz for 2 min) of dog isolated saphenous vein strips pre-incubated with tritiated noradrenaline increased the overflow of tritium of which about 80% was noradrenaline. 5-Hydroxytryptamine (5-HT; 1.0 x 10-9-1.0 x 10-7 mol litre-1) and methysergide (3.0 x 10-8-3.0 x 10-6 mol litre-1) inhibited the induced overflow of total tritium by a maximum of 78 +/- 4% and 47 +/- 7% respectively (mean +/- s.e. mean, n=6 for each). Methysergide was about 30 times less potent than 5-HT and the maximum inhibition obtained was less than with 5-HT. Both compounds inhibited electrically-induced contractions and overflow of tritiated noradrenaline. Their inhibitory actions on tritium overflow were little affected by phentolamine (1.0 x 10-6 mol litre-1) or cyproheptadine (1.0 x 10-6 mol litre-1), nor was the inhibitory effect of methysergide on electrically induced contractions antagonized by atropine, mepyramine, cimetidine or propranolol. The findings suggest Protonix 30 Mg that the prejunctional inhibitory effect of methysergide may be mediated via stimulation of a 5-HT receptor which, unlike the D-receptor, is not blocked by cyproheptadine. The possibility that the pre-junctional 5-HT receptor in the dog saphenous vein is the same as the post-junctional receptor in this preparation is discussed.

The susceptibility of fetal endocrine pancreas to the diabetogenic action of cyproheptadine was investigated. Cyproheptadine (5 or 11 mg/kg) or water (control) was given orally once daily to pregnant rats on Days 13.5-20.5 or on Days 19.5-20.5 of gestation. Fetuses were obtained by cesarean section 24 hr after the last dose. Serum and pancreatic immunoreactive insulin and serum glucose from maternal and fetal animals were measured. Differences in maternal pancreatic insulin, serum insulin, and glucose between control and treated groups were not detected. In contrast, fetal pancreatic and serum insulin concentrations in animals exposed to 2 or 8 doses of cyproheptadine were less than 50% those of control. Drug treatment did not alter fetal Protonix Yellow Pill pancreatic glucagon, pancreatic somatostatin, serum glucose, pancreas weight, or body weight. The drug-related depletion of fetal pancreatic insulin was reversible; the level returned to normal 3 days after cessation of the drug treatment. A similar depletion of fetal insulin was observed after 8 oral doses (11 mg/kg) of desmethylcyproheptadine, a metabolite which lacks the antiserotonin-antihistaminic properties of the parent compound. In vitro experiments showed that cyproheptadine inhibited the biosynthesis and release of insulin in fetal rat pancreas. These results indicate that cyproheptadine, when given to pregnant rats using a dose which produces no apparent effects in the maternal endocrine pancreas, causes abnormalities in the function of the insulin-secreting B cells in the fetal endocrine pancreas.

A high-performance liquid chromatography-tandem mass spectrometric (LC-MS/MS) method has been developed and validated for the quantitative analysis of loratadine, an H1 histamine antagonist, in human dried blood spot (DBS) samples following a single self-administered 10 or 20mg oral dose. The samples were produced by spotting approximately 30μl of whole blood onto PE-226 cards. Two 3-mm discs were cut from the DBS samples and extracted using aqueous methanol containing the internal standard. After transfer and drying of the resulting sample extract, the reconstituted residues were chromatographed using a Waters XSelect C18 column and isocratic elution for MS/MS detection. The possible impact due to hematocrit, volume of blood sample spotted, storage temperature, and humidity, on the accuracy of measured DBS results were investigated. The results showed that only spotted blood volume might have an impact; a small volume (10μl) tended Calan Reviews to give a larger negative bias in the measured value than the large volume ones (≥20μl). The current method was fully validated over a dynamic range of 0.200-20.0ng/ml with correlation coefficients (r(2)) for three validation batches equal to or better than 0.990. The intra-day accuracy and precision at the LLOQ were -11.5 to 0.0% bias and 6.4 to 8.9% CV, respectively. For the other QC samples (0.600, 3.00, 10.0 and 15.0ng/ml), the precision ranged from 4.2 to 9.8% CV and from 6.3 to 8.1% CV, respectively, in the intra-day and inter-day evaluations; the accuracy ranged from -1.7 to 10.0% and 2.7 to 5.3% bias, respectively, in the intra-day and inter-day batches. Loratadine is stable in the DBS samples for at least 271 days at ambient temperature in a desiccator, for at least 24h at 60°C and under 80% relative humidity, followed by re-conditioning at ambient temperature in a desiccator. The current methodology has been applied to determine the loratadine levels in DBS samples collected by subjects in a clinical research study to evaluate pharmacokinetic sampling in point-of-care setting.

Desloratadine is a biologically active Persantine Medication Classification metabolite of the second-generation antihistamine loratadine. Desloratadine is a highly selective peripheral H1 receptor antagonist that is significantly more potent than loratadine. Results of in vitro and in vivo studies have suggested that desloratadine has anti-allergic effects that are unrelated to its ability to antagonise the effects of histamine. Desloratadine inhibits the expression of cell adhesion molecules, inhibits the generation and release of inflammatory mediators and cytokines, attenuates eosinophil chemotaxis, adhesion and superoxide generation. Studies in animals indicate that desloratadine does not cross the blood-brain barrier and therefore does not cause sedation and does not impair cognition or psychomotor performance. Desloratadine has an excellent overall safety profile. It has no effect on QRS and QTc intervals and does not cause arrhythmias. Desloratadine is not associated with any significant changes in gastrointestinal function. In clinical studies, oral desloratadine is rapidly absorbed and bioavailability is not affected by ingestion with food or grapefruit juice. The half-life of desloratadine in humans is 27 h; the linear kinetic profile is unaltered by race or gender. Desloratadine is not a substrate for P-glycoprotein or organic anion transport polypeptide and the drug does not appear to be metabolised to a significant extent by the cytochrome P450 CYP3A4 pathway. It therefore may be safely administered with ketoconazole, erythromycin, fluoxetine, or azithromycin. Clinically, desloratadine effectively controls both nasal and non-nasal symptoms of seasonal allergic rhinitis (SAR), including nasal congestion. Desloratadine also provides significant relief of SAR symptoms in patients with co-existing asthma and is effective in the treatment of chronic idiopathic urticaria. Desloratadine improves quality of life and is well-tolerated.

Pituitary adenomas were obtained from eight of nine patients with Cushing's disease, and the surrounding tissues as well were obtained from six of nine patients. ACTH, beta-lipotropin (beta-LPH), beta-endorphin, GH, TSH, LH, and PRL concentrations in these tissues were determined by RIA. Immunoreactive ACTH and beta-endorphin (beta-endorphin + beta-LPH) were present in high concentrations in all adenomas, and low concentrations were found in the surrounding tissues, except for one patient. As compared to levels seen in normal pituitary tissue, the GH concentration in the surrounding tissues was suppressed in five of six cases. TSH and LH concentrations were suppressed in four and three cases, respectively. The PRL concentration was not suppressed in any of the six patients studied. These four hormones were not detected in any adenoma. Plasma GH, TSH, and LH responses to various stimuli which were suppressed preoperatively returned to normal in most of the patients after adenomectomy. Basal plasma cortisol concentrations were normal or subnormal and were suppressed by the administration of 1 mg dexamethasone after adenomectomy, in contrast to the lack of such suppression preoperatively. ACTH and beta-endorphin secretion were stimulated by lysine-8-vasopressin and suppressed by dexamethasone and cyproheptadine in vitro.
