Abrupt cessation my precipitate angina, MI, arrhythmias, or rebound HTN; discontinue by tapering over 1-2 weeks. Immediate-release form is metoprolol tartrate; extended-release form is metoprolol succinate. When switching from immediate release to extended-release product, use same total daily dose. The immediate and extended release products may not give same clinical response on mg:mg basis; monitor response and side effects when interchanging between metoprolol products. Concomitant amiodarone, digoxin, disopyramide, or non-dihydropyridine calcium channel blockers may increase the risk of bradycardia. Monitor closely for HF exacerbation and hypotension when titrating dose. Switching from immediate-release to extended-release: Use same total daily dose of metoprolol Switching between oral and IV dosage forms: Equivalent beta-blocking effect is achieved in 2.5:1 (oral-to-IV) ratio Dizziness (10%) Headache (10%) Tiredness (10%) Depression (5%) Diarrhea (5%) Pruritus (5%) Bradycardia (9%) Rash (5%) Dyspnea (1-3%) Cold extremities (1%) Constipation (1%) Dyspepsia (1%) Heart failure (1%) Hypotension (1%) Nausea (1%) Flatulence (1%) Heartburn (1%) Xerostomia (1%) Wheezing (1%) Bronchospasm (1%) Anxiety/nervousness Hallusinations Paresthesia Hepatitis Vomiting Arthralgia Male impotence Reversible alopecia Agranulocytosis Dry eyes Worsening of psoriasis Pyronie’s disease Sweating Photosensitivity Taste disturbance Lopressor and Toprol XL only Ischemic heart disease may be exacerbated after abrupt withdrawal Hypersensitivity to catecholamines has been observed during withdrawal Exacerbation of angina and, in some cases, myocardial infarction (MI) may occur after abrupt discontinuance When long-term beta blocker therapy (particularly with ischemic heart disease) is discontinued, dosage should be gradually reduced over 1-2 weeks with careful monitoring If angina worsens markedly or acute coronary insufficiency develops, beta-blocker administration should be promptly reinitiated, at least temporarily (in addition to other measures appropriate for unstable angina) Patients should be warned against interruption or discontinuance of beta-blocker therapy without physician advice Because coronary artery disease (CAD) is common and may be unrecognized, beta-blocker therapy must be discontinued slowly, even in patients treated only for hypertension Use with caution in cerebrovascular insufficiency, CHF, cardiomegaly, myasthenia gravis, hyperthyroidism or thyrotoxicosis (may mask signs or symptoms), liver disease, renal impairment, peripheral vascular disease, psoriasis (may cause exacerbation of psoriasis) May exacerbate bronchospastic disease; monitor closely Beta blockers can cause myocardial depression and may precipitate heart failure and cardiogenic shock Sudden discontinuance can exacerbate angina and lead to MI and ventricular arrhythmias in patients with CAD Worsening cardiac failure may occur during up-titration of metoprolol succinate; if such symptoms occur, increase diuretics and restore clinical stability before advancing the dose of metoprolol succinate; it may be necessary to lower the dose of metoprolol succinate or temporarily discontinue it Bradycardia, including sinus pause, heart block, and cardiac arrest, has been reported; patients with 1° atrioventricular block, sinus node dysfunction, or conduction disorders may be at increased risk Increased risk of stroke after surgery May potentiate hypoglycemia in patients with diabetes mellitus and may mask signs and symptoms Avoid starting high-dose regimen of extended-release metoprolol in patients undergoing noncardiac surgery; use in patients with cardiovascular risk factors is associated with bradycardia, hypotension, stroke, and death Long-term beta blockers should not be routinely withdrawn before major surgery; however, impaired ability of the heart to respond to reflex adrenergic stimuli may augment risks of general anesthesia and surgical procedures Metoprolol loses beta-receptor selectivity at high doses and in poor metabolizers If drug is administered for tachycardia secondary to pheochromocytoma, it should be given in combination with an alpha blocker (which should be started before metoprolol is started) While taking beta blockers, patients with history of severe anaphylactic reaction to variety of allergens may be more reactive to repeated challenge Extended release tablet should not be withdrawn routinely prior to major surgery Hydrochlorothiazide, can cause an idiosyncratic reaction, resulting in acute transient myopia and acute angle-closure glaucoma, which can lead to permanent vision loss if not treated; discontinue hydrochlorothiazide as rapidly as possible if symptoms occur; prompt medical or surgical treatments may need to be considered if intraocular pressure remains uncontrolled; risk factors for developing acute angle-closure glaucoma may include history of sulfonamide or penicillin allergy Caution in patients with history of psychiatric illness; may cause or exacerbate CNS depression Beta-blockers can precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease There are no adequate and well-controlled studies in pregnant women Limited data on the use of metoprolol in pregnant women Risk to fetus/mother is unknown; because animal reproduction studies are not always predictive of human response, use if clearly needed Bioavailability: 40-50% (immediate-release) ; 65-77% (extended-release) relative to immediate release Onset: 20 min (IV), when infused over 10 min;

Popularity: 16th most commonly prescribed drug between 2002 – 2008 (U. S.) Classes: Beta-adrenergic blocker, antianginal, antiarrhythmic, antihypertensive, antimigraine. Treatment Uses — Angina pectoris, heart failure, mild to moderate high blood pressure, and to improve survival after heart attacks. Also effective in treating arrhythmias, pheochrocytoma, essential tremor and neuroleptic drug induced movement disorders, preventing migraine headaches, reducing eye pressures in glaucoma, and reducing the frequency of vasovagal syncopal episodes. May have a role in treatment of aggressive behavior, panic attacks, and reducing atherosclerosis. Widely used (off-label) by performers to reduce symptoms of stage fright. We performed a post hoc analysis of the METOCARD-CNIC (effect of METOprolol of CARDioprote Ctio N during an acute myocardial Infar Ction) trial, which randomized anterior STEMI patients to IV metoprolol or control before mechanical reperfusion. Treated patients were divided into short- and long-interval groups, split by the median time from 15 mg metoprolol bolus to reperfusion. We also performed a controlled validation study in 51 pigs subjected to 45 min ischemia/reperfusion. Pigs were allocated to IV metoprolol with a long (−25 min) or short (−5 min) pre-perfusion interval, IV metoprolol post-reperfusion ( 60 min), or IV vehicle. Cardiac magnetic resonance (CMR) was performed in the acute and chronic phases in both clinical and experimental settings. For 218 patients (105 receiving IV metoprolol), the median time from 15 mg metoprolol bolus to reperfusion was 53 min. Compared with patients in the short-interval group, those with longer metoprolol exposure had smaller infarcts (22.9 g vs. Metoprolol iv administration Metoprolol, Sudden death after IV metoprolol administration in a patient with.
