Metoprolol is indicated for the treatment of angina, heart failure, myocardial infarction, atrial fibrillation, atrial flutter and hypertension. Some off-label uses of metoprolol include supraventricular tachycardia and thyroid storm. All the indications of metoprolol are part of cardiovascular diseases.
What is the role of metoprolol in the body?
It has a role as a beta-adrenergic antagonist, an antihypertensive agent, a xenobiotic and an environmental contaminant. It is a propanolamine, an aromatic ether, a secondary alcohol and a secondary amino compound.
How long does it take for metoprolol to be absorbed?
When metoprolol is administered orally, it is almost completely absorbed in the gastrointestinal tract. The maximum serum concentration is achieved 20 min after intravenous administration and 1-2 hours after oral administration. The bioavailability of metoprolol is of 100% when administered intravenously and when administered orally it presents about 50% for the tartrate derivative and 40% for the succinate derivative. The absorption of metoprolol in the form of the tartrate derivative is increased by the concomitant administration of food.
How long does metoprolol stay in the atmosphere?
Vapor-phase metoprolol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 0.22 days. Particulate-phase metoprolol will be removed from the atmosphere by wet and dry deposition.
What is the rate constant for the vapor phase reaction of metoprolol with photochemically produced hydroxy?
The rate constant for the vapor-phase reaction of metoprolol with photochemically-produced hydroxyl radicals has been estimated as 1.5X10-10 cu cm/molecule-sec at 25 °C (SRC) using a structure estimation method (1). This corresponds to an atmospheric half-life of about 0.22 dayss at an atmospheric concentration of 5.5X10+5 hydroxyl radicals per cu cm (1). Metoprolol is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups (3) nor to directly photolyze due to the lack of absorption in the environmental UV spectrum (>290 nm) (SRC).
How is metoprolol released into the atmosphere?
Metoprolol's production and use as an antihypertensive , antianginal, and antiarrhythmic drug may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 2.8X10-7 mm Hg at 25 °C indicates metoprolol will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase metoprolol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 0.22 days. Particulate-phase metoprolol will be removed from the atmosphere by wet and dry deposition. If released to soil, metoprolol is expected to have high mobility based upon an estimated Koc of 62. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.1X10-11 atm-cu m/mole. An estimated pKa of metoprolol is 9.6, indicating that this compound will primarily exist in the protonated form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts. Metoprolol is not expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, metoprolol is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon metoprolol's estimated Henry's Law constant. An estimated BCF of 1.3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to metoprolol may occur through inhalation and dermal contact with this compound at workplaces where metoprolol is produced or used. Monitoring data indicate that the general population may be exposed to metoprolol by ingestion of this compound as a drug or by contact with wastewater or surface water contaminated with metoprolol. (SRC)

How to treat metoprolol?
Consult poison control/toxicology early in the course. Treatment choices include volume resuscitation, activated charcoal, whole bowel irrigation, nasogastric lavage, atropine, glucagon, calcium gluconate/calcium chloride, high-dose insulin, vasopressors, Intralipid, transcutaneous, or transvenous pacemaker. Cardiac status and a current fluid balance will guide volume resuscitation. Activated charcoal is typically given 1 g/kg and usually only has efficacy if dosed within 1 to 2 hours of ingestion.[15] If the patient has any altered mentation, caution is necessary to the possibility of aspiration. Whole bowel irrigation should be a consideration for extended-release preparations or large quantity ingestion.
How long does metoprolol take to work?
The extended-release preparation has a similar onset of action and a duration of up to 24 hours. Metabolism of metoprolol is hepatic with excretion in the urine. If there is renal impairment, there is no dosage adjustment necessary. If there is a history of hepatic impairment, slowly increasing titrated doses to effect should be used. With the use of intravenous (IV) administration, cardiac monitor, including ECG heart rate and blood pressure, should be constant. Oral administration heart rate rhythm and blood pressure require monitoring. [14]
How long does metoprolol succinate stay in the system?
It is 11% bound to serum albumin. The half-life of metoprolol is about 3 to 4 hours in most patients for non-extended release tabs. Metoprolol excretion principally occurs via the kidneys.[10] Metoprolol succinate produces more level drug concentrations as compared to metoprolol tartrate, which has more peak-to-trough variation. However, despite these differences in pharmacokinetics, studies have concluded that both agents produce similar clinical effects, both acute and chronic. [11]
Does metoprolol cause tinnitus?
The primary adverse effects of metoprolol include heart failure exacerbation, fatigue, depression, bradycardia or heart block, hypotension, bronchospasm, cold extremities, dizziness, decreased libido, diarrhea, tinnitus, decreased exercise tolerance, glucose intolerance, and may mask hypoglycemia. Abrupt cessation of the drug may lead to a withdrawal syndrome that could cause angina or myocardial infarction. Tachycardia and hypertension are both common in withdrawal syndrome. [13]
Is metoprolol FDA approved?
Metoprolol is FDA-approved to treat angina, heart failure, myocardial infarction, atrial fibrillation/flutter, and hypertension. Off-label uses include supraventricular tachycardia and thyroid storm. Both oral and intravenous preparations are available. There are immediate and extended-release preparations available orally. There is controversy regarding the selection of beta-blockers in the management of the above conditions. There is also conflicting evidence regarding the optimal choice of a particular beta-blocker in treating each specific disease. This activity will highlight the mechanism of action, adverse event profile, pharmacology, monitoring, and relevant interactions of metoprolol, pertinent for members of the interprofessional team in the treatment of patients with conditions where it is of clinical value.
Is metoprolol contraindicated for heart failure?
Metoprolol is contraindicated in patients with sick sinus syndrome, second or third-degree heart block (in the absence of pacemaker), decompensated heart failure, hypotension, and documented hypersensitivity to the drug or components. Also, caution is necessary for patients with a history of noncompliance as the abrupt cessation of the drug can lead to withdrawal syndromes, including angina and myocardial infarction. Patients who have ingested cocaine or methamphetamine have traditionally had a contraindication to the use of selective beta-blocker such as metoprolol. This observation has its basis on case reports, and there is no strong evidence that they cause any deleterious effects. Regardless, agents such as labetalol, which have alpha and beta activity, or calcium channel blockers should be used in these cases. Metoprolol is a pregnancy risk factor Category C drug. [14]
Does beta blocker help with myocardial infarction?
Several randomized trials in the 1980s showed a mortality benefit for beta-blockers in acute myocardial infarction. [4][5][6] The Metoprolol Atherosclerosis Prevention in Hypertensives (MAPHY) trial specifically showed a benefit of metoprolol over diuretics regarding sudden cardiac death as well as myocardial infarction. [7] A large randomized trial of over 50,000 patients in the 1990s showed metoprolol to reduce mortality and re-infarction when used chronically after myocardial infarction.[8] Beta-blockers have demonstrated prognostic benefit and reduce mortality in the treatment of chronic heart failure. The carvedilol or metoprolol European trial (COMET) enrolled patients with stable heart failure and compared each drug head-to-head. Carvedilol was associated with a statistically significantly lower risk of all-cause death.[9] However, recent trials have had conflicting evidence on whether selective beta-1 blockers such as metoprolol have any benefit over other beta-blockers like carvedilol.
