Which of the following is Symbicort?

Symbicort is a combination medication that contains budesonide, which is an inhaled corticosteroid, and formoterol, a long-acting beta-agonist. This combination works synergistically to improve asthma control by reducing inflammation (through budesonide) and providing bronchial dilation (through formoterol). This dual action helps to manage symptoms such as wheezing and shortness of breath, making it effective for patients with chronic asthma or chronic obstructive pulmonary disease (COPD).

The other options listed are different combinations or medications altogether. Fluticasone and salmeterol are components of a different combination inhaler, Advair. Ipratropium bromide and albuterol refer to a rescue inhaler often used for acute symptoms and not a long-term control medication like Symbicort. Methylprednisolone is an oral corticosteroid, and racemic epinephrine is typically used for severe asthmatic episodes, and neither is part of the Symbicort formulation.
