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; onset may be immediate, depending on clinical setting; 1-2 hr (PO) Duration: 3-6 hr (PO); duration is dose-related; 24 hr (ER); 5-8 hr (IV) Peak plasma time: 1.5-2 hr (immediate-release); 3.3 hr (extended-release) Therapeutic range: 35-212 ng/m L The above information is provided for general informational and educational purposes only.

Two weeks if no change to ineffective use of metoprolol succinate sustained-release tablets, 95 mg was given orally once a day, 4 weeks a course of treatment; the control group, amlodipine besylate tablets 2.5–5 mg once a day, one time follow-up a week, 4 weeks a course of treatment. Results In the treatment group patients, metoprolol succinate sustained-release tablets in the treatment 4 weeks before and after treatment, blood pressure and heart rate were compared, there was a significant difference (p If you wish to reuse any or all of this article please use the link below which will take you to the Copyright Clearance Center’s Rights Link service.

Includes dosages for Hypertension, Congestive Heart Failure, Myocardial. However, these trials mainly tested the non-vasodilating β1 selective BBs atenolol and metoprolol which are still the most commonly prescribed BBs in the USA. METOPROLOL TARTRATE IMMEDIATE RELEASE TABLETS: Initial dose: 100 mg orally per day in single or divided doses Maintenance dose: 100 to 450 mg orally per day Comments: -May increase dose at weekly, or longer, intervals. -Lower once-daily doses may not maintain full effect at the end of the 24-hour period; larger or more frequent daily doses may be required. Beta-1 selectivity diminishes as the dose is increased. METOPROLOL SUCCINATE EXTENDED RELEASE TABLETS: Initial dose: 25 to 100 mg orally once a day Maintenance dose: 100 to 400 mg orally once a day Comments: -May increase dose at weekly, or longer, intervals. Initial dose: -Metoprolol tartrate immediate release tablets: 50 mg orally twice a day -Metoprolol succinate extended release tablets: 100 mg orally once a day Maintenance dose: 100 to 400 mg per day Comments: -Increase dose at weekly intervals until optimum clinical response has been obtained or pronounced slowing of heart rate occurs. METOPROLOL TARTRATE: Early Treatment: Initial dose: 5 mg IV every 2 minutes as tolerated for 3 doses -Patients tolerant of full IV dose (15 mg): 50 mg orally every 6 hours starting 15 minutes after the last IV dose and continued for 48 hours -Patients intolerant of full IV dose (15 mg): 25 or 50 mg orally every 6 hours depending on the degree of intolerance starting 15 minutes after the last IV dose or as soon as their clinical condition allows Late Treatment: Maintenance dose: 100 mg orally twice a day Comments: -Patients with contraindications to treatment during the early phase of suspected or definite myocardial infarction, patients who appear not to tolerate the full early treatment, and patients in whom the physician wishes to delay therapy for any other reason should be started on 100 mg orally twice a day as soon as their clinical condition allows. -Continue therapy for at least 3 months; efficacy beyond 3 months has not been conclusively established; data from studies with other beta blockers suggest a treatment duration of 1 to 3 years. Use: Treatment of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality. Treatment with the IV formulation can be initiated as soon as the patient's clinical condition allows. Alternatively, treatment can begin within 3 to 10 days of the acute event. Β-Blockers (BBs) are an essential class of cardiovascular medications for reducing morbidity and mortality in patients with heart failure (HF). However, a large body of data indicates that BBs should not be used as first-line therapy for hypertension (HTN). Additionally, new data have questioned the role of BBs in the treatment of stable coronary heart disease (CHD). However, these trials mainly tested the non-vasodilating β selective BBs (atenolol and metoprolol) which are still the most commonly prescribed BBs in the USA. Newer generation BBs, such as the vasodilating BBs carvedilol and nebivolol, have been shown not only to be better tolerated than non-vasodilating BBs, but also these agents do not increase the risk of diabetes mellitus (DM), atherogenic dyslipidaemia or weight gain. Moreover, carvedilol has the most evidence for reducing morbidity and mortality in patients with HF and those who have experienced an acute myocardial infarction (AMI). This review discusses the cornerstone clinical trials that have tested BBs in the settings of HTN, HF and AMI.
