/BOXED WARNING/ Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of ergotamine tartrate with potent CYP 3A4 inhibitors including protease inhibitors and macrolide antibiotics. Because CYP 3A4 inhibition elevates the serum levels of ergotamine tartrate, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Hence, concomitant use of these medications is contraindicated.

On February 26, 2007, FDA warned 20 firms that manufacture or distribute unapproved drug preparations containing ergotamine tartrate of the agency's intention to take enforcement action (e.g., seizure, injunction, other judicial proceeding) against all firms attempting to manufacture or distribute such preparations after April 25, 2007, or August 25, 2007, respectively, without an approved new drug application (NDA). Manufacturers' labelings for most of these unapproved preparations omitted critical drug interaction warnings, and the preparations did not undergo FDA review of safety, efficacy, quality, and labeling. There currently are FDA-approved ergotamine-containing preparations on the US market, which are not affected by these actions.

The most common adverse effects of ergotamine tartrate are nausea and vomiting occurring in about 10% of patients receiving the drug. Abdominal pain; weakness in the legs; muscle pain or stiffness in the extremities, neck, or shoulders; and numbness and tingling of fingers and toes are common and usually do not require discontinuance of the drug. However, if these symptoms are persistent, ergotamine should be stopped.

There is a wide variation in sensitivity to the vasoconstrictor effects of ergotamine and, although adverse effects are most common with long-term therapy using higher than usual doses, vasospasm also has occurred rarely with short-term therapy or usual doses of the drug. Vasoconstriction may cause coronary insufficiency with precipitation or aggravation of angina pectoris and possibly myocardial infarction and death. Cold, numb, painful extremities with or without paresthesia have occurred; pulses of the affected extremity are often diminished or absent. Claudication of the legs may occur. When the drug is discontinued, symptoms of impaired peripheral circulation are usually reversible. Gangrene of extremities may develop but is rare with usual doses in patients without peripheral vascular disease or other contraindications.

For use as therapy to abort or prevent vascular headache, e.g., migraine, migraine variants, or so called "histaminic cephalalgia".
Ergotamine is a vasoconstrictor and alpha adrenoreceptor antagonist. The pharmacological properties of ergotamine are extremely complex; some of its actions are unrelated to each other, and even mutually antagonistic. The drug has partial agonist and/or antagonist activity against tryptaminergic, dopaminergic and alpha adrenergic receptors depending upon their site, and it is a highly active uterine stimulant. It causes constriction of peripheral and cranial blood vessels and produces depression of central vasomotor centers. The pain of a migraine attack is believed to be due to greatly increased amplitude of pulsations in the cranial arteries, especially the meningeal branches of the external carotid artery. Ergotamine reduces extracranial blood flow, causes a decline in the amplitude of pulsation in the cranial arteries, and decreases hyperperfusion of the territory of the basilar artery. It does not reduce cerebral hemispheric blood flow.

This study investigated if genetic differences exhibited in endophyte-resistant and -susceptible mouse lines had persisted after 13 generations in which the integrity of lines was maintained yet selection ceased. Experimental groups were mouse lines fed an endophyte-free (E-) or -infected (E+) diet. The in vitro metabolism of the ergot alkaloid ergotamine in mouse liver microsomes was characterized by LC-MS/MS and compared between both lines before and after exposure to E+ feed. ... Microsomal incubations produced nine predominate peaks in the HPLC assay. The peaks were confirmed by LC-MS/MS to be ergotamine, ergotamine epimer, monohydroxylated metabolites (M1, M2, M1e, M2e) and dihydroxylated metabolites (M3--5). A gender difference for metabolite formation was observed on the E- diet, in that females produced a greater amount of M1, M1e and M3--5 than males. When challenged with the E+ diet, mice showed differences in concentration of M3 for line (resistant > susceptible) and gender (female > male) and of M4 and M5 for gender (female > male). Gender differences in the metabolism of ergotamine have not been shown before in these lines of mice or other species used to study ergot alkaloid metabolism. ...

Ergotamine acts on migraine by one of two proposed mechanisms: 1) activation of 5-HT1D receptors located on intracranial blood vessels, including those on arterio-venous anastomoses, leads to vasoconstriction, which correlates with the relief of migraine headache, and 2) activation of 5-HT1D receptors on sensory nerve endings of the trigeminal system results in the inhibition of pro-inflammatory neuropeptide release.
Ergotamine has complex pharmacologic effects. In therapeutic doses, ergotamine causes peripheral vasoconstriction (if the vascular tone is low) primarily by stimulating alpha-adrenergic receptors; however, the drug causes vasodilation in very hypertonic vessels. With higher doses, ergotamine is also a competitive alpha-adrenergic blocker, but this effect is somewhat masked by the drug's alpha-adrenergic agonist activity. With therapeutic doses, ergotamine also inhibits reuptake of norepinephrine, thereby maintaining a high concentration of circulating norepinephrine and increasing ergotamine's vasoconstrictor action. Ergotamine has greater vasoconstrictor activity than the other ergot alkaloids but less alpha-adrenergic blocking activity than dihydroergotamine. Ergotamine is a weaker antagonist of serotonin (5-hydroxytryptamine) than is methysergide, but ergotamine does reduce the increased rate of platelet aggregation induced by serotonin. The mechanism by which ergotamine aborts vascular headaches is probably direct vasoconstriction of the dilated carotid artery bed with a concomitant decrease in the amplitude of pulsations; the drug's effects on catecholamines and serotonin are also at least partly involved.

Sumatriptan, dihydroergotamine and methysergide inhibit 1% formalin-induced nociception by activation of peripheral 5-HT1B/1D receptors. This study set out to investigate the pharmacological profile of the antinociception produced by intrathecal and intraplantar administration of ergotamine (a 5-HT1B/1D and 5-HT5A/5B receptor agonist) and valerenic acid (a partial agonist at 5-HT5A receptors). Intraplantar injection of 1% formalin in the right hind paw resulted in spontaneous flinching behavior of the injected hindpaw of female Wistar rats. Intrathecal ergotamine (15 nmol) or valerenic acid (1 nmol) blocked in a dose dependent manner formalin-induced nociception. The antinociception by intrathecal ergotamine (15 nmol) or valerenic acid (1 nmol) was partly or completely blocked by intrathecal administration of the antagonists: (i) methiothepin (non-selective 5-HT5A/5B; 0.01-0.1 nmol); (ii) SB-699551 (selective 5-HT5A; up to 10 nmol); (iii) anti-5-HT5A antibody; (iv) SB-224289 (selective 5-HT1B; 0.1-1 nmol); or (v) BRL-15572 (selective 5-HT1D; 0.1-1 nmol). Likewise, antinociception by intraplantar ergotamine (15 nmol) and valerenic acid (10 nmol) was: (i) partially blocked by methiothepin (1 nmol), SB-699551 (10 nmol) or SB-224289 (1 nmol); and (ii) abolished by BRL-15572 (1 nmol). The above doses of antagonists (which did not affect per se the formalin-induced nociception) were high enough to completely block their respective receptors. Our results suggest that ergotamine and valerenic acid produce antinociception via 5-HT5A and 5-HT1B/1D receptors located at both spinal and peripheral sites. This provides new evidence for understanding the modulation of nociceptive pathways in inflammatory pain.

It has previously been suggested that ergotamine produces external carotid vasoconstriction in vagosympathectomised dogs via 5-HT1B/1D receptors and alpha2-adrenoceptors. The present study has reanalyzed this suggestion by using more selective antagonists alone and in combination. Fifty-two anesthetized dogs were prepared for ultrasonic measurements of external carotid blood flow. The animals were divided into thirteen groups (n=4 each) receiving an i.v. bolus injection of, either physiological saline (0.3 mL/kg; control), or the antagonists SB224289 (300 ug/kg; 5-HT1B), BRL15572 (300 ug /kg; 5-HT1D), rauwolscine (300 ug /kg; alpha2), SB224289 + BRL15572 (300 ug /kg each), SB224289 + rauwolscine (300 ug /kg each), BRL15572 + rauwolscine (300 ug/kg each), rauwolscine (300 ug/kg) + prazosin (100 ug/kg; alpha1), SB224289 (300 ug /kg) + prazosin (100 ug /kg), SB224289 (300 ug/kg) + rauwolscine (300 ug/kg) + prazosin (100 ug/kg), SB224289 (300 ug/kg) + prazosin (100 ug/kg) + BRL44408 (1,000 ug/kg; alpha2A), SB224289 (300 ug /kg) + prazosin (100 ug/kg)+ imiloxan (1,000 ug/kg; alpha2B), or SB224289 (300 ug /kg) + prazosin (100 ug/kg) + MK912 (300 ug/kg; alpha2C). Each group received consecutive 1-min intracarotid infusions of ergotamine (0.56, 1, 1.8, 3.1, 5.6, 10 and 18 ug/min), following a cumulative schedule. In saline-pretreated animals, ergotamine induced dose-dependent decreases in external carotid blood flow without affecting arterial blood pressure or heart rate. These control responses were: unaffected by SB224289, BRL15572, rauwolscine or the combinations of SB224289 + BRL15572, BRL15572 + rauwolscine, rauwolscine + prazosin, SB224289 + prazosin, or SB224289 + prazosin + imiloxan; slightly blocked by SB224289 + rauwolscine; and markedly blocked by SB224289 + rauwolscine + prazosin, SB224289 + prazosin + BRL44408 or SB224289 + prazosin + MK912. Thus, the cranio-selective vasoconstriction elicited by ergotamine in dogs is predominantly mediated by 5-HT1B receptors as well as alpha2A/2C-adrenoceptor subtypes and, to a lesser extent, by alpha1-adrenoceptors.

Changes in the diameter of extracranial and intracranial arteries resulting in changes in cerebral blood flow have previously been assumed to be the most important pathophysiological factor in migraine. 20 normal subjects, and three groups of patients (n = 29) with migraine were investigated by means of transcranial Doppler sonography. Blood flow velocities in the middle cerebral (MCA) and in basilar (BA) arteries were measured. Data from patients were obtained in the interval between migraine attacks, during migraine attacks and following treatment with either ergotamine (0.5 mg im; n = 1O); frunarizine, a calcium overload blocker (20 mg iv; n =13); or a 5-HTl-like agonist (sumatriptan, 4 mg sc; n = 6). Ergotamine and sumatriptan are constrictors of cerebral arteries in animal experiments. The arithmetic mean of flow velocity in the BA was reduced in normal subjects (45 cm/s) as compared with patients with migraine measured in between attacks (53 cm/s). Mean flow velocity in MCA was not different in normals (72.5 cm/s) as compared with migraineurs (75 cm/s). Neither ergotamine nor the 5-HTl agonist and flunarizine resulted in a significant change in blood flow velocity in MCA and BA. This was true irrespective of whether the drugs were given in the headache-free period, during a migraine attack or during the withdrawal phase of drug-induced headache. Ergotamine was effective in improving headache during migraine attacks and sumatriptan attenuated headache during drug withdrawal from chronic analgesic intake. These results indicate that the action of ergotamine and the 5-HTl-receptor agonist is probably not mediated by their vasoconstrictor action on cerebral arteries.
