Answer
Bronchodilators
Epinephrine causes vasoconstriction, bronchodilation, and increased cardiac output. The effects of albuterol and theophylline are more focused on bronchodilation.
Albuterol (Proventil HFA, Ventolin HFA, ProAir HFA, VoSpire ER)
Albuterol is an adjunctive treatment for bronchospasm given by nebulization, and it is a beta-agonist useful to treat bronchospasm refractory to epinephrine. It relaxes bronchial smooth muscle by action on beta2-receptors and has little effect on cardiac muscle contractility.
