Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat high blood pressure, angina, and a number of conditions involving an abnormally fast heart rate.[4] It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines.[4] It is a selective β1 receptor blocker medication.[4] It is taken by mouth or is given intravenously.[4]
Common side effects include trouble sleeping, feeling tired, feeling faint, and abdominal discomfort.[4] Large doses may cause serious toxicity.[5][6] Risk in pregnancy has not been ruled out.[4][7] It appears to be safe in breastfeeding.[8] The metabolism of metoprolol can vary widely among patients, often as a result of hepatic impairment[9] or CYP2D6 polymorphism.[10]
Metoprolol was first made in 1969, patented in 1970, and approved for medical use in 1978.[11][12][13] It is on the World Health Organization's List of Essential Medicines.[14] It is available as a generic medication.[4] In 2021, it was the sixth most commonly prescribed medication in the United States, with more than 65 million prescriptions.[15][16]
