Chronic Obstructive Pulmonary Disease »
Chronic obstructive pulmonary disease (COPD) is comprised primarily of three related conditions - chronic bronchitis, chronic asthma, and emphysema. In each condition there is chronic obstruction of the flow of air through the airways and out of the lungs, and the obstruction generally is permanent and may be progressive over time.
While asthma features obstruction to the flow of air out of the lungs, usually, the obstruction is reversible. Between "attacks" of asthma the flow of air through the airways typically is normal. These patients do not have COPD. However, if asthma is left untreated, the chronic inflammation associated with this disease can cause the airway obstruction to become fixed. That is, between attacks, the asthmatic patient may then have abnormal air flow. This process is referred to as lung remodeling. These asthma patients with a fixed component of airway obstruction are also considered to have COPD.

Metaproterenol is in the FDA pregnancy category C. This means that it is not known whether metaproterenol will be harmful to an unborn baby. Do not take this medication without first talking to your doctor if you are pregnant or could become pregnant during treatment.
It is not known whether metaproterenol passes into breast milk. Do not take metaproterenol without first talking to your doctor if you are breast-feeding a baby.
Take metaproterenol exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.
Take the metaproterenol tablets with a full glass of water.

It is important to take metaproterenol regularly to get the most benefit.
Seek medical attention if you notice that you require more than your usual or more than the maximum amount of any asthma medication in a 24-hour period. An increased need for medication could be an early sign of a serious asthma attack.
Your doctor may want you to have lung function tests or other medical evaluations during treatment with metaproterenol to monitor progress and side effects.
Store metaproterenol at room temperature away from moisture and heat.
