Almotriptan: uses, dosing, side effects & brands

Serious cardiac reactions, including myocardial infarction, have occurred following the use of almotriptan (almotriptan malate) tablets. These reactions are extremely rare and most have been reported in patients with risk factors predictive of CAD. Reactions reported in association with triptans have included coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, and ventricular fibrillation [see Contraindications (4.1) and Warnings and Precautions (5.1) ] . The following adverse reactions are discussed in more detail in other sections of the labeling: • Risk of Myocardial Ischemia and Infarction and Other Adverse Cardiac Events [see Warnings and Precautions (5.1) ] • Sensations of Pain, Tightness, Pressure in the Chest and/or Throat, Neck, and Jaw [see Warnings and Precautions (5.2) ] • Cerebrovascular Events and Fatalities [see Warnings and Precautions (5.3) ] • Other Vasospasm-Related Events, Including Peripheral Vascular Ischemia and Colonic Ischemia [see Warnings and Precautions (5.4) ] • Serotonin Syndrome [see Warnings and Precautions (5.5) ] • Increases in Blood Pressure [see Warnings and Precautions (5.7) ] Adverse events were assessed in controlled clinical trials that included 1840 adult patients who received one or two doses of almotriptan tablets and 386 adult patients who received placebo. The most common adverse…

Ischemic heart disease, coronary artery vasospasm, or other significant underlying cardiovascular disease ( 4.1 ) • Cerebrovascular syndromes (e.g., history of stroke or TIA) ( 4.2 ) • Peripheral vascular disease (including ischemic bowel disease) ( 4.3 ) • Uncontrolled hypertension ( 4.4 ) • Do not use almotriptan tablets within 24 hours of an ergotamine-containing, or ergot-type medication, or of another 5-HT 1 agonist, e.g., another triptan ( 4.5 , 4.6 ) • Hemiplegic or basilar migraine ( 4.7 ) • Known hypersensitivity to almotriptan tablets ( 4.8 ) 4.1 Ischemic or Vasospastic Coronary Artery Disease, or Other Significant Underlying Cardiovascular Disease Do not use almotriptan tablets (almotriptan malate) in patients with ischemic heart disease (angina pectoris, history of myocardial infarction, or documented silent ischemia), or in patients who have symptoms or findings consistent with ischemic heart disease, coronary artery vasospasm, including Prinzmetal’s variant angina, or other significant underlying cardiovascular disease [see Warnings and Precautions (5.1) ] . 4.2 Cerebrovascular Syndromes Do not use almotriptan tablets in patients with cerebrovascular syndromes including (but not limited to) stroke of any type as well as transient ischemic attacks [see Warnings and Precautions (5.3) ] . 4.3 Peripheral Vascular Disease Do not use almotriptan tablets in patients with peripheral vascular disease including (but not limited to) ischemic bowel disease [see Warnings and Precautions (5.4) ] . 4.4 Uncontrolled Hypertension Because almotriptan may increase blood pressure, do not use almotriptan tablets in patients with uncontrolled hypertension [see Warnings and Precautions (5.7) ] . 4.5 Ergotamine-Containing and Ergot-Type Medications Do not use almotriptan tablets and ergotamine-containing or ergot-derived medications like dihydroergotamine, ergotamine tartrate, or methysergide within 24 hours of each other [see Drug Interactions (7.1) ] . 4.6 Concomitant Use with 5-HT 1 Agonists (e.g., Triptans) Almotriptan tablets and other 5-HT 1 agonists (e.g., triptans) should not be administered within 24 hours of each other [see Warnings and Precautions (5.1) and (5.2) ]. 4.7 Hemiplegic or Basilar Migraine Do not use almotriptan tablets in patients with hemiplegic or basilar migraine. 4.8 Hypersensitivity Almotriptan tablets are contraindicated in patients with known hypersensitivity to almotriptan or any of their inactive ingredients.

Do not use almotriptan tablets and ergotamine-containing or ergot-type medications within 24 hours of each other ( 4.5 , 7.1 ) • Do not use almotriptan tablets and other 5-HT 1 agonist (e.g., triptans) within 24 hours of each other ( 4.6 , 7.2 ) • SSRI or SNRI: life-threatening serotonin syndrome reported during combined use with triptans ( 5.5 , 7.3 ) • Ketoconazole: use single dose of almotriptan tablets 6.25 mg; maximum almotriptan tablets daily dose 12.5 mg ( 7.4 ) 7.1 Ergot-Containing Drugs These drugs have been reported to cause prolonged vasospastic reactions. Because, in theory, vasospastic effects may be additive, ergotamine-containing or ergot-type medications (like dihydroergotamine, ergotamine tartrate, or methysergide) and almotriptan tablets (almotriptan malate) should not be used within 24 hours of each other [see Contraindications (4.5) ] . 7.2 5-HT 1 Agonists (e.g., Triptans) Concomitant use of other 5-HT 1 agonists (e.g., triptans) within 24 hours of treatment with almotriptan tablets is contraindicated [see Contraindications (4.6) ] . 7.3 Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors Cases of life-threatening serotonin syndrome have been reported during combined use of triptans and selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.5) , Clinical Pharmacology (12.3) ] . 7.4 Ketoconazole and Other Potent CYP3A4 Inhibitors Co-administration of almotriptan and oral ketoconazole, a potent CYP3A4 inhibitor, resulted in an approximately 60% increase in exposure of almotriptan. Increased exposures to almotriptan may be expected when almotriptan is used concomitantly with other potent CYP3A4 inhibitors [see Clinical Pharmacology (12.3) ] . In patients concomitantly using potent CYP3A4 inhibitors, the recommended starting dose of almotriptan tablets is 6.25 mg. The maximum daily dose should not exceed 12.5 mg within a 24-hour period. Concomitant use of almotriptan tablets and potent CYP3A4 inhibitors should be avoided in patients with renal or hepatic impairment [see Clinical Pharmacology (12.3) ] .
