Facts (generated by robot; please edit if you find it inaccurate)

• The reversibility of airway obstruction to an inhaled beta 2-adrenergic agent is less satisfactory after methacholine testing in asthmatic subjects.
• We previously showed in a retrospective study that the acute response to an inhaled beta-2-adrenergic agent is marked in late asthmatic reactions (J Allergy Clin Immunology 1990;85:834).
• If the physical exam suggests Cardiogenic Shock then a continuous infusion of an adrenergic agent is required to augment contractility.
• However, there is a wide individual variation in the dose required to produce a- effects in the shocked patient (up to 20g/kg/min) hence the use of dopamine as a primary adrenergic agent is being re-examined.
• A preferred beta-blocking adrenergic agent is metoprolol or a pharmaceutically acceptable salt thereof.
