* Umeclidinium and vilanterol inhalation powder (Anoro Ellipta) is a new drug for treating chronic obstructive pulmonary disease.
* It's used once daily for long-term maintenance and cannot be used to treat acute bronchospasm or asthma.
* As a combination of an anticholinergic and a long-acting b2-agonist, Anoro Ellipta carries the same warnings regarding drug–drug interactions and adverse effects as other drugs in those classes.
