Were you looking for information on Metaproterenol? Metatproteronol is a common misspelling of metaproterenol.
Metaproterenol is no longer available in the United States. The manufacturer of this medication decided to stop making it in order to comply with regulations concerning chlorofluorocarbons (CFCs), chemicals that may deplete the ozone layer. The product was rarely used anymore; had it been more popular, the manufacturer probably would have chosen to reformulate it without CFCs, instead of just discontinuing it.
Available only by prescription, metaproterenol (Alupent®) is a drug used to treat bronchospasms caused by asthma or chronic obstructive pulmonary disease (COPD). The drug works by opening up the airways so that more air can get into and through the lungs. It's important to note that the drug is usually taken only when needed for an asthma attack. It is generally not taken on a regular basis. Prior to taking metaproterenol, tell your healthcare provider if you have high blood pressure, a fast heart rate, or any allergies.
