DOSAGE AND ADMINISTRATION Procedure For best results, dosage should start at the first sign of an attack. Early Administration Gives Maximum Effectiveness. At the first sign of an attack or to relieve symptoms after onset of an attack, one 2 mg tablet is placed under the tongue. Another tablet should be taken at half-hour intervals thereafter, if necessary, but dosage must not exceed three tablets in any 24 hour period. Total weekly dosage should not exceed five tablets (10 mg) in any one week. Ergomar ® Sublingual Tablets should not be used for chronic daily administration.

Side Effects Overview

ADVERSE REACTIONS Cardiovascular: Vasoconstrictive complications of a serious nature may occur at times. These include ischemia, cyanosis, absence of pulse, cold extremities, gangrene, precordial distress and pain, EKG changes and muscle pains. Although these effects occur most commonly with long-term therapy at relatively high doses, they have also been reported with short-term or normal doses. Other cardiovascular adverse effects include transient tachycardia or bradycardia and hypertension. Gastrointestinal: Nausea and vomiting. Neurological: paresthesias, numbness, weakness, and vertigo. Allergic: Localized edema and itching. Fibrotic Complications: ( See WARNINGS ).

Cảnh báo & Thận trọng

WARNINGS CYP 3A4 Inhibitors (e.g., Macrolide Antibiotics and Protease Inhibitors) Coadministration of ergotamine with potent CYP 3A4 inhibitors such as protease inhibitors or macrolide antibiotics has been associated with serious adverse events; for this reason, these drugs should not be given concomitantly with ergotamine ( See CONTRAINDICATIONS ). While these reactions have not been reported with less potent CYP 3A4 inhibitors, there is a potential risk for serious toxicity including vasospasm when these drugs are used with ergotamine. Examples of less potent CYP 3A4 inhibitors include: saquinavir, nefazodone, fluconazole, fluoxetine, grapefruit juice, fluvoxamine, zileuton, metronidazole, and clotrimazole. These lists are not exhaustive, and the prescriber should consider the effects on CYP 3A4 of other agents being considered for concomitant use with ergotamine. Fibrotic Complications There have been a few reports of patients on ergotamine tartrate and caffeine therapy developing retroperitoneal and/or pleuropulmonary fibrosis. There have also been rare reports of fibrotic thickening of the aortic, mitral, tricuspid, and/or pulmonary valves with long-term continuous use of ergotamine tartrate and caffeine. Ergomar ® Sublingual Tablets should not be used for chronic daily administration (See DOSAGE AND ADMINISTRATION ).

Chống chỉ định

CONTRAINDICATIONS Coadministration of ergotamine with potent CYP 3A4 inhibitors (ritonavir, nelfinavir, indinavir, erythromycin, clarithromycin and troleandomycin) has been associated with acute ergot toxicity (ergotism) characterized by vasospasm and ischemia of the extremities ( See PRECAUTIONS: Drug Interactions ), with some cases resulting in amputation. There have been rare reports of cerebral ischemia in patients on protease inhibitor therapy when ergotamine was coadministered, at least one resulting in death. Because of the increased risk for ergotism and other serious vasospastic adverse events, ergotamine use is contraindicated with these drugs and other potent inhibitors of CYP 3A4 (e.g., ketoconazole, itraconazole) (See WARNINGS: CYP 3A4 Inhibitors ). Ergomar ® Sublingual Tablets may cause fetal harm when administered to pregnant women. Ergomar ® Sublingual Tablets are contraindicated in women who are or may become pregnant. If this drug is used during pregnancy or if the patient becomes pregnant while taking this product, the patient should be apprised of the potential hazard to the fetus. Peripheral vascular disease, coronary heart disease, hypertension, impaired hepatic or renal function and sepsis. Hypersensitivity to any of the components.

Dược động học

Pharmacokinetics: Interactions Pharmacokinetic interactions (increased blood levels of ergotamine) have been reported in patients treated orally with ergotamine and macrolide antibiotics (e.g., troleandomycin, clarithromycin, erythromycin), and in patients treated orally with ergotamine and protease inhibitors (e.g., ritonavir) presumably due to inhibition of cytochrome P450 3A metabolism of ergotamine ( See CONTRAINDICATIONS ). Ergotamine has also been shown to be an inhibitor of cytochrome P450 3A catalyzed reactions. No pharmacokinetic interactions involving other cytochrome P450 isoenzymes are known.
