There is no direct conversion from Tenormin (atenolol) to Toprol XL (metoprolol succinate). Generally, when switching between the two, your doctor will pick a similar "potency range" for the specific medication. In addition, there are published guidelines and dosage recommendations based on the indication the drug is being used for. Atenolol comes in the following dosages: As mentioned, there is no direct conversion between atenolol and metoprolol succinate. However, if you were taking 25 mg of atenolol, it makes sense that you would be initiated on a low dose of metoprolol succinate, around 25 to 50 mg. In addition, the appropriate dosage depends on the specific indication being treated (e.g. Below are some common indications and appropriate dosages based on those indications. Metoprolol belongs to the calss of medications know as beta-blockers. It has many functions, including lowering pulse and blood pressure. Are you getting low blood pressure and/or dizziness when you take Cialis with your blood pressure drug regimen? It can also be used in people who have weak heart muscles to stop/slow the progression of the disease and perhaps even Toprol xl (specifically that formulation, not metoprolol tartrate) and Carvedilol (generic or Coreg (carvedilol) brand name) have been shown in large, well controlled clinical trials to slow and sometimes reverse the damage of heart failure. I would think the hydrazine and the clonidine would be the most likely offenders based on mechanism of action. They operate by blocking a malfunctioning feedback loop of hormones and signaling molecules, ultimately by blocking the effect of adrenaline on the heart. Generally losartan, Coreg, (carvedilol) and amlodipine are well tolerated with the Cialis family of drugs. But that's quite a BP combo; take my prediction with a grain of salt! Read more Ace inhibitors are great medications for BP and diabetes and scledoderma hypertensive crisis. Read more In patients with COPD or asthma , cardioselective beta blockers like atenolol are felt to be superior to Inderal (propranolol) which also has possible harmful effects on the bronchial tree and could produce wheezing(bronchospasm). However, in some patientds they may adversely affect the kidneys, specially if there is underlying renovascular disease. This may be a concern in someone like you who has copd. Your physician is best to advise you, however especially if you're doing well on inderal (propranolol). Read more See 1 more doctor answer Generic toprol xl is metoprolol succinate. Toprol is the long acting formulation of same medication.
If you have a heart attack, your doctor may give you metoprolol tartrate (Lopressor). This drug can prevent another heart attack from occurring. However, you should be careful not to confuse it with metoprolol succinate (Toprol-XL). While the two drugs share the same first word and both treat heart-related issues, metoprolol succinate doesn’t prevent or treat a heart attack in people who’ve already had a heart attack. Learn more about the similarities and differences between these two drugs. Metoprolol tartrate and metoprolol succinate contain the same active medication: metoprolol. These salt forms, tartrate and succinate, are approved by the U. Food and Drug Administration (FDA) for different conditions. Both medications belong to a class of drugs called beta-blockers, which work by relaxing your blood vessels and slowing down your heart rate. 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;
