Control of tachyarrhythmias, especially supraventricular tachyarrhythmias. The injection can be repeated at 5 minute intervals until a satisfactory response has been obtained. Injection to patients with a systolic blood pressure below 100 mm Hg should only be given with special care. The same dosage can also be used to control arrhythmias developing during anaesthesia. Injection should be initiated in a coronary care or similar unit when the patient's haemodynamic condition has stabilised. The second or third dose should not be given if the systolic blood pressure is 0.26 seconds, or if there is any aggravation of dyspnoea or cold sweating. Pain relief may also decrease the need for opiate analgesics. Initially up to 5 mg injected intravenously at a rate of 1-2 mg per minute. at induction is usually sufficient to prevent the development of arrhythmias during anaesthesia. every 2 minutes to a maximum of 15 mg total as determined by blood pressure and heart rate. Injection in acute myocardial infarction reduces infarct size and the incidence of ventricular fibrillation. Injection has been shown to reduce mortality when administered to patients with acute myocardial infarction. A total dose of 10-15 mg generally proves sufficient. Further injections of 2 mg may be given as required to a maximum overall dose of 10 mg. Oral therapy should commence 15 minutes after the last injection with 50 mg every 6 hours for 48 hours. Because of the risk of a pronounced drop of blood pressure, the I. Patients who fail to tolerate the full intravenous dose should be given half the suggested oral dose. Dose adjustment is normally not needed in patients suffering from liver cirrhosis because metoprolol has a low protein binding (5 – 10 %). However, in patients with severe hepatic dysfunction a reduction in dosage may be necessary. • Decompensated cardiac failure (pulmonary oedema, hypoperfusion or hypotension). nolvadex 20mg By Mike Mc Evoy Generic Name: Metoprolol (multiple manufacturers) Common Brand Name: Lopressor (Novartis Pharmaceuticals – U.

By Najm Haque, PGY2 Atrial fibrillation with rapid ventricular response is a common emergency room problem. Patient with stable blood pressure who present in Afib with RVR need medications to control their heart rate (unstable patients require more cardioversion). Traditionally, these patients receive beta blockers or calcium channel blockers in IV form for rate control. The most common medications used in the US are metoprolol and diltiazem, but it is unclear which is superior. Fromm et al This study was published in the Journal of Emergency Medicine in April 2015 and compared how fast rate control was achieved in diltiazem vs metoprolol. This was a prospective, double-blind study which compared the effects of both medications at 30 minutes, as well as looking at mean decrease in heart rate, and adverse effects. Patients were randomized and either received Diltiazem 0.25 mg/kg IVP (maximum dose of 30mg) or Metoprolol 0.15mg/kg IVP (maximum dose of 10mg). Metoprolol is used for a number of conditions, including hypertension, angina, acute myocardial infarction, supraventricular tachycardia, ventricular tachycardia, congestive heart failure, and prevention of migraine headaches. receptors in the heart, metoprolol is also prescribed for off-label use in performance anxiety, social anxiety disorder, and other anxiety disorders. Metoprolol is sold in formulations that can be taken by mouth or given intravenously. Side effects, especially with higher doses, include dizziness, drowsiness, fatigue, diarrhea, unusual dreams, trouble sleeping, depression, and vision problems. Metoprolol may also reduce blood flow to the hands or feet, causing them to feel numb and cold; smoking may worsen this effect. Due to the high penetration across the blood-brain barrier, lipophilic beta blockers such as propranolol and metoprolol are more likely than other less lipophilic beta blockers to cause sleep disturbances such as insomnia and vivid dreams and nightmares. Serious side effects that are advised to be reported immediately include symptoms of bradycardia (resting heart rate slower than 60 beats per minute), persistent symptoms of dizziness, fainting and unusual fatigue, bluish discoloration of the fingers and toes, numbness/tingling/swelling of the hands or feet, sexual dysfunction, erectile dysfunction, hair loss, mental/mood changes, depression, breathing difficulty, cough, dyslipidemia and increased thirst.
