Pheochromocytoma crisis caused by contemporary ergotamine, caffeine, and nimesulide administration.

Pheochromocytoma is a rare tumor that secretes excess catecholamines. Pheochromocytoma crises may be precipitated by the use of several drugs. This article describes the case of a patient affected by pheochromocytoma in whom multiple organ failure developed after contemporary administration of ergotamine, caffeine, and nimesulide. The patient recovered completely long after surgical intervention.

Abortive migraine therapy with oral naproxen sodium plus metoclopramide plus ergotamine tartrate with caffeine.

The oral tablet combination, (550 mgs. of naproxen sodium plus 10 mgs. of metoclopramide plus 1 mg. of ergotamine tartrate plus 100 mgs. of caffeine), was retrospectively studied in 63 patients who used it to abort migraine headaches. On the average, 84% of the headaches were totally aborted; minor side effects occurred in 40% of the patients, and 87% of the patients considered the combination superior to all prior treatments.

Naproxen sodium versus ergotamine tartrate in the treatment of acute migraine attacks.

A double-blind parallel study compared the efficacy and safety of naproxen sodium (NPX) and ergotamine tartrate (ERG) as abortive therapy for acute headache in 79 patients with classical or common migraine. The design study was of the double-blind design. Forty-two patients completed the study. Discontinuation of treatment was generally due to lack of efficacy or adverse reactions. NPX was significantly better than ERG in the overall efficacy of treatment rated by the patients (p less than 004). NPX was comparable to ERG in reducing the severity and duration of the headache and its associated symptoms. In classical migraine, NPX was better than ERG in alleviating the severity of headache. Patients in the NPX group tended to use less rescue medication. There was no significant difference in the frequency of side-effects reported by the patients under NPX or ERG. This study demonstrates that NPX is as safe as ERG, and somewhat more effective in acute migraine attacks (although the difference is not statistically significant) and that migrainous patients tend to prefer NPX to ERG in treating their acute migraine headaches.

Cervicogenic headache: responses to nitroglycerin, oxygen, ergotamine and morphine.

The responses in cervicogenic headache to four different agents have been studied. Nitroglycerin was given sublingually to 27 patients. Eighteen patients got more than 20% increase of their headache. Of those with any headache increase at all, 12 got bilateral and 12 unilateral pain. The typical late cluster headache response to nitroglycerin was not seen in cervicogenic headache. The provocative effect of nitroglycerin seemed less marked in cervicogenic than in cluster headache. Oxygen inhalation, a frequently used treatment for cluster headache, was given to 14 patients with cervicogenic headache. In general, the effect seemed uncertain and probably clearly inferior to the effect in cluster headache. Ergotamine treatment (given to 13 patients) also seemed to be of little avail in cervicogenic headache. Morphine injections given to 11 cervicogenic headache patients resulted in "marked" improvement in 4, but complete pain freedom was only seen in 2 cases. In our opinion, the present results add further evidence to the view that different etiologic and pathogenetic factors underlie cervicogenic headache and cluster headache.

Comparative efficacy and safety of calcium carbasalate plus metoclopramide versus ergotamine tartrate plus caffeine in the treatment of acute migraine attacks.

This randomized, double-blind, double-dummy, multicenter, parallel-group study aimed at comparing the efficacy and safety of calcium carbasalate (equivalent to 900 mg aspirin) plus metoclopramide 10 mg (CM) with ergotamine tartrate 1 mg plus caffeine 100 mg (EC) administered in the treatment of 2 acute migraine attacks. A total of 296 patients fulfilling the International Headache Society diagnostic criteria for migraine were enrolled. In total, one or two migraine attacks were treated in 268 and 235 patients, respectively. The primary endpoint for the first treated attack was headache relief, with intensity decreasing from moderate or severe to mild or absent 2 h after drug intake. Usual secondary efficacy endpoints were assessed. A superiority of CM over EC was observed for both treated attacks for the main endpoint: success in 54 versus 36%, p = 0.003 for the first attack and 60 versus 44%, p = 0.02 for the second attack. CM was also significantly superior to EC during the first attack for complete headache relief (20 vs. 8%, p = 0.006), nausea (42 vs. 63%, p = 0. 007) and willingness to take the drug again (90 vs. 80%, p = 0.043). The global efficacy evaluation, rated by the investigators, was significantly more favorable to CM for both attacks (p = 0.001 for the first attack and p = 0.02 for the second). The patients' evaluation was significant for the first attack (p = 0.002). The global incidence of adverse events was 45% higher with EC, though not significant (32 vs. 22%, p = 0.075). They were most often unspecific and mild to moderate in intensity. Gastrointestinal side effects were significantly less frequent with CM than EC (7 vs. 21%, p = 0.001). Thus, CM is more effective and has a better gastrointestinal safety than EC in the acute treatment of migraine attacks.

Efficacy, tolerability and safety of oral eletriptan and ergotamine plus caffeine (Cafergot) in the acute treatment of migraine: a multicentre, randomised, double-blind, placebo-controlled comparison.

The 5-HT(1B/1D/1F) agonist eletriptan, at an oral dose of 80 mg, has been shown to be more efficacious than sumatriptan 100 mg and placebo in the treatment of migraine attacks with or without aura. Another commonly prescribed oral treatment for migraine attacks is Cafergot (1 mg ergotamine tartrate with 100 mg caffeine per tablet). The efficacy, tolerability and safety of 40- and 80-mg doses of eletriptan and 2 tablets of Cafergot were compared in a double-blind, randomised, placebo-controlled, parallel-group trial involving 733 migraine patients. Patients recorded symptoms at baseline (before treatment) and 1, 2, 4 and 24 h after dosing. Headache intensity was assessed on a 4-point scale (3 = severe pain, 2 = moderate pain, 1 = mild pain, 0 = no pain). Significantly more eletriptan-treated patients (80 mg, 68%; 40 mg, 54%) than Cafergot-treated patients (33%; p < 0.001) reported headache response (improvement from moderate-to-severe to mild or no pain) at 2 h. Substantially more eletriptan recipients reported no pain (80 mg, 38%; 40 mg, 28%; Cafergot, 10%; placebo, 5%; p < 0.001). Eletriptan headache response rates at 1 h were significantly higher (80 mg, 39%; 40 mg, 29%; Cafergot, 13%; placebo, 13%; p < 0.002 for each comparison). Both doses of eletriptan were significantly more effective than Cafergot in reducing nausea (p < 0.0001), photophobia (80 mg, p < 0.0001; 40 mg, p < 0.002), phonophobia (80 mg, p < 0.0001; 40 mg, p < 0.003) and functional impairment (p < or = 0.001) at 2 h. Adverse events were generally mild or moderate and transient. This randomised trial shows that oral eletriptan is more efficacious in the acute treatment of migraine than oral Cafergot and is well tolerated.

Failure of ergotamine to alter the lipolytic effect of somatotropin in dogs.

Hypophysectomized dogs were injected intravenously with bovine somatotropin (GH), and plasma free fatty acid (FFA) concentrations were measured over a period of 2 h. The response consisted of an initial reduction in the concentration of plasma FFA followed by a rebound and a delayed rise above baseline values. When the animals were given a single intravenous injection of ergotamine tartrate 30 min prior to the administration of GH, the biphasic pattern with the sluggish rise in plasma FFA was retained. This finding is contrary to the results of identical experiments conducted by us with dihydroergotamine, which proved to be a potent amplifier of the lipolytic effect of GH. Since the only difference between these two compounds is the presence or absence of the double bond at C9 and C10 of the lysergic acid moiety, it appears that unless this bond is saturated the alkaloid is not capable of functioning as a biological amplifier.

Microneurographic evidence of sudden sympathetic withdrawal in carotid sinus syncope; treatment with ergotamine.

A proportion of patients with carotid sinus syncope (CSS) remain symptomatic even after pacemaker implantation because of persistence of a vasodepressor component. We report a patient with CSS whose syncopal episodes could be reproduced by carotid sinus massage and were due to profound hypotension associated with sudden sympathetic withdrawal, based on direct measurements of sympathetic nerve traffic. A double-blind trial with inhaled ergotamine provided significant symptomatic relief.

Effect of consuming fungus-infected and fungus-free tall fescue and ergotamine tartrate on selected physiological variables of cattle in environmentally controlled conditions.

Two experiments were conducted to determine the physiological responses of consuming a fungus-free (FF) or fungus-infected (INF) tall fescue diet (Exp. 1) or the FF diet plus ergotamine tartrate at 30 ppm (FF/ET, Exp. 2) in a thermoneutral (21 degrees C) or heat-stressed environment (32 degrees C, dry bulb; 10 degrees C dew point). Treatment periods lasted 28 d after a 10-d adaptation period. Experiment 1 was replicated three times, and Exp. 2 was replicated twice, with eight Holstein steers in each replicate (mean BW = 185 kg). Feed intake (FI), rectal temperature (RT), and respiration rate (RR) were recorded daily, and heart rate (HR) and infrared temperatures at the ear canal (ECT), ear tip (ETT), pastern (PT), coronary band (CBT), and tail tip (TTT) were recorded weekly. Consumption of INF and FF/ET compared with FF diets decreased (P less than .10) FI, HR, ECT, PT, CBT, and TTT and elevated (P less than .10) RT and RR by 2.8, 2.77 kg/d; 17, 23 beats/min; .8, 1.1 degrees C; .9, 1.1 degrees C; .8, .9 degrees C; 1.1, 2.6 degrees C; .3, .5 degrees C; and 8, 8 breaths/min; respectively. Ear-tip temperature was reduced (P less than .10) 1.6 degrees C by consumption of INF but not by consumption of FF/ET. Reduction of peripheral temperatures is indicative of reduced blood flow to peripheral areas as a result of vasoconstriction.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of ergotamine and ergonovine on thermal regulation and cardiovascular function in cattle.

Research was conducted to determine whether individual ergot alkaloids could induce signs of fescue toxicosis. Nine Angus heifers received single i.v. injections of ergotamine tartrate, ergonovine maleate, and saline vehicle in a simple cross-over design. Each heifer received a different compound each week and all treatments during the study. Physiological traits measured 15 min before and 30, 60, and 90 min after treatment were respiration rate, rectal and skin temperatures, systolic and diastolic pressures, and heart rate. Blood samples were collected 5 min before and 105 min after treatments to assess plasma prolactin concentrations. Heifers were on a fescue-free diet in drylot. Ambient temperature averaged 35 degrees C during data collection. A treatment x time interaction existed (P < .05) for respiration rate and prolactin concentrations. Ergot alkaloids altered (P < .05) all traits across time, except rectal temperature. Heifers under the influence of ergot alkaloids exhibited significantly lower skin temperature, heart rate, and prolactin and had higher respiration rate and blood pressure. Results indicated that individual ergot alkaloids administered i.v. induced signs of fescue toxicosis in cattle.

Effect of ergotamine and ergonovine on plasma concentrations of thyroid hormones and cortisol in cattle.

Plasma samples from two experiments were processed to determine whether ergot alkaloids associated with endophyte-infected tall fescue altered peripheral thyroxine (T4), triiodothyronine (T3), or cortisol concentrations in cattle. In Exp. 1, seven Angus steers (294 kg) received i.v. bolus injections of saline (SAL), ergonovine maleate (7 mg; EM), or ergotamine tartrate (7 mg; ET) at weekly intervals, and they received all treatments during the study. Blood was sampled every 15 min for 5 h, and treatments were given after h 1. Mean ambient temperature was 34 degrees C. Treatment x time affected plasma concentrations of T3 (P < .05) and of cortisol (P < .001) but not that of T4 (P > .2). Plasma T3 concentrations were not affected by SAL, whereas concentrations increased (P < .01) after either EM or ET treatment. Plasma cortisol concentrations were not altered by SAL or EM, but they were increased (P < .001) by ET treatment. In Exp. 2, six Holstein cows (499 kg) nursing calves received a bolus i.v. injection of SAL, EM (9.5 mg), or ET (9.5 mg) per estrous cycle, and all treatments were given over three cycles. Blood was sampled every 20 min for 5 h; treatments were given after h 1. Mean ambient temperature was 26 degrees C. Treatment x time affected T3 (P = .08) and cortisol (P < .001) and tended to influence (P = .16) T4 concentrations. Plasma T3, T4, and cortisol concentrations were not influenced by SAL treatment. Plasma T3 was higher (P < or = .01) after EM or ET treatment compared with pretreatment concentrations. Concentrations of T4 during the 4 h after EM and ET were increased (P < .001) compared with pretreatment. Plasma cortisol concentrations were not altered by EM but were increased (P < .001) by ET. Ergot alkaloids implicated as contributing agents to fescue toxicosis alter plasma concentrations of hormones important to metabolic and thermoregulatory functions in cattle.

Effect of cod-liver oil extract on the buccal permeation of ergotamine tartrate.

Ergotamine tartrate (ET) is used clinically in the treatment of migraines. However, the bioavailability of ET is rather poor following oral administration. Therefore, we tried to improve ET delivery using buccal administration. The purpose of this study was to investigate the characteristics of the permeation of ET through the hamster cheek pouch in vitro using a two-chamber diffusion cell, and to evaluate the effect of permeation enhancers on the transbuccal delivery of ET. Cod-liver oil extract (CLOE), polyoxyethylene hydrogenated castor oil (HCO 60), sodium glycocholate (GC), and sodium caprate (CA) were selected as premeation enhancers considering their low irritancy of the mucosa. When the enhancers were added to the donor cell at a 5% concentration each, the ET permeation rate markedly increased compared with that in a control not containing enhancer. Among these enhancers, CLOE exhibited the greatest effect. Because CLOE is composed of 16 kinds of fatty acids, the enhancement action of each of the major components was separately determined. As major fatty acids, palmitic acid, oleic acid, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) were selected and their enhancing effects were studied. The enhancing effect of each fatty acid was significantly lower than that of CLOE.

Ergotamine-induced upper extremity ischemia: a case report.

Ergotamine-induced limb ischemia is an extremely rare case. We present a case of a 64-year-old man, who developed ischemia on the right upper extremity due to long-term use of Ergot for migraine headache. Angiography revealed diffused, smooth, and tapered narrowing of the brachial artery. The patient was successfully treated with intravenous nitroprusside.

Successful treatment of ergotamine poisoning with sodium nitroprusside.

A case of ergotamine overdosage which produced vascular insufficiency in a 26-year-old female is described. She was treated successfully with the intravenous infusions of sodium nitroprusside and low molecular weight dextran, and anticoagulation with heparin. It is suggested that sodium nitroprusside may represent the drug of first choice in this condition.

[Systemic arterial spasms. Ergotamine tartrate].

The problem of the toxic effects of ergotism is raised by two cases of acute lower limb ischaemia observed in young patients. Although commonly encountered up to the 20th century, the problem is now reappearing sporadically from iatrogenic causes. The clinical features and treatment of ergotism are discussed. Prophylaxis is based on two main principles: the respect of contraindications, the most important being hypertension, coronary insufficiency, arteriopathies, acrocyanosis and thrombophlebitis, and less importantly, the association of tetracycline type antimicrobials, triacetyloleandomycin and phenothiazine; on the other hand, attention must also be paid to the instructions on its use, particularly with respect to the maximum dosage, 4 mg/day per os, 10 mg/week per os. The treatment should be given intermittently and not continuously. Full knowledge of the composition of composite drugs is required as many drugs are commercialised with their ergotamine content masked. This justifies, if there is still need, constant pharmacovigilance.

[Is triacetyl oleandomycin-ergotamine tartrate combination dangerous?].

The authors report a case of ischaemia of all four limbs in an adolescent following the simultaneous ingestion of triacetyl oleandomycin and ergotamine tartrate in low dosage. Two cases involving this same association of medications have appeared in the literature and attention is therefore drawn to the possible danger of use of these two drugs together.
