Metaproterenol Sulfate Pharmacology

Metaproterenol, a synthetic amine, is structurally and pharmacologically similar to isoproterenol. Metaproterenol is used exclusively as a bronchodilator. The pharmacologic effects of beta adrenergic agonist drugs, such as Metaproterenol, are at least in part attributable to stimulation through beta adrenergic receptors of intracellular adenyl cyclase, the enzyme which catalyzes the conversion of adenosine triphosphate (ATP) to cyclic- 3',5'- adenosine monophosphate (c-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.

Metaproterenol Sulfate Patient Information

Patient’s Instructions for Use Alupent®

(metaproterenol sulfate USP) Inhalation Aerosol

1. Insert metal canister into clear end of mouthpiece.

2. Remove protective cap, invert canister and shake well before each use.

3. Avoid spraying in eyes.

4. Enclose mouthpiece with the lips. The base of the canister should be held vertically. The Alupent® canister is to be used only with the white Alupent® Inhalation Aerosol mouthpiece. This mouthpiece should not be used with other aerosol medications.

5. Exhale deeply, then inhale slowly through the mouth and at the same time firmly press once on the upended canister base; continue to inhale deeply. Hold your breath for a few seconds and then remove the mouthpiece from the mouth and exhale slowly.

One inhalation is often enough to obtain relief. The inhalation can be repeated once or twice, if necessary, or as your physician directs. Wait at least two minutes before repeating the inhalation. In most cases, the dose should not be repeated more often than every 3 to 4 hours. No more than 12 inhalations should be taken in one day.

6. Replace protective cap after use.

Do not exceed the dose prescribed by your physician. If difficulty in breathing persists, contact your physician immediately.

Note: When full, the container holds enough medication for at least 200 inhalations: at least 100 inhalations are in the sample unit. Check regularly, by shaking the cylinder or container, to determine whether it contains any medication. When it first seems empty, there are still about ten doses left. Refill containers for the plastic mouthpiece are available when prescribed by your physician.

Keep the mouthpiece clean. Wash with hot water. If soap is used, rinse thoroughly with plain water.

Never open the container holding the medication. Opening it is dangerous and renders the contents useless.

Caution: Contents Under Pressure. Do not puncture or incinerate container. Do not expose to heat or store at temperatures above 120°F. Keep out of reach of small children
