Sympathomimetics (adrenergics) form a class of drugs which mimic the autonomic nervous system.
Sympathomimetic drugs are used primarily for bronchodilation. They relieve bronchospasm by relaxing the smooth muscles of the bronchioles. They are used in the treatment of asthma, bronchitis, and emphysema. Some of these drugs also have other uses, for example as vasopressors and in the treatment of glaucoma. Isoproterenol is an example of a sympathomimetic, it dilates constricted bronchial tubes, stimulates the heart muscle, and dilates blood vessels. (Facts and Comparisons 1999)
Can cause hyperglycemia (Smith 1992). Limit sugar and monitor diabetics (see under diabetes).
Electrolytes should be maintained (especially potassium) (Pronsky 1999).
Albuterol may affect vitamin B6 absorption (Martinez 1996).
Avoid caffeine. (Pronsky 1999)
Ephedra (Ma Huang) has approval status by the German Commission E regarding its sympathomimetic action. However, this action may be potentiated if taken in combination with MAO inhibitors. (Blumenthal 1998)
