-
- BRAND NAMES (Manufacturers)
-
- Alupent (Boehringer Ingelheim)
- Metaprel (Dorsey)
-
- TYPE OF DRUG
-
- Bronchodilator
-
- INGREDIENT
-
- metaproterenol
-
- DOSAGE FORMS
-
- Tablets (10 mg and 20 mg)
- Oral syrup (10 mg per 5-ml spoonful)
- Inhalation aerosol (each spray delivers 0.65 mg)
- Solution for nebulization (0.6% and 5%)
-
- STORAGE
-
- Metaproterenol tablets and oral syrup should be stored at room
- temperature in tightly closed, light-resistant containers. The solution for
- nebulization should be stored in the refrigerator. The inhalation aerosol
- should be stored at room temperature away from excessive heat--the contents
- are pressurized, and the container can explode if heated. Metaproterenol
- syrup and solution should not be used if they turn brown or contain particles.
-
- USES
-
- Metaproterenol is used to relieve wheezing and shortness of breath caused
- by lung diseases such as asthma, bronchitis, and emphysema. This drug acts
- directly on the muscles of the bronchi (breathing tubes) to relieve
- bronchospasm (muscle contractions of the bronchi), thereby allowing air to
- move to and from the lungs.
-
- TREATMENT
-
- In order to lessen stomach upset, you can take metaproterenol tablets or
- oral syrup with food (unless your doctor directs you to do otherwise).
- The oral syrup form of this medication should be measured carefully with
- a specially designed 5-ml measuring spoon. An ordinary kitchen teaspoon is
- not accurate enough.
- The inhalation aerosol form of this medication is usually packaged with
- an instruction sheet. Read the directions carefully before using this
- medication. The container should be shaken well just before each use. The
- contents tend to settle on the bottom, so it is necessary to shake the
- container to distribute the ingredients evenly and equalize the doses. If
- more than one inhalation is necessary, wait at least one full minute between
- doses, so that you receive the full benefit of the first dose.
- If you miss a dose of this medication and remember within an hour, take
- it; then follow your regular schedule for the next dose. If you miss the dose
- by more than an hour or so, just wait until the next scheduled dose. Do not
- double the dose.
- If you are also using an aerosol corticosteroid (such as beclomethasone,
- dexamethasone, or triamcinolone), use the metaproterenol inhalation first and
- wait about five minutes before using the corticosteroid inhalation, unless
- otherwise directed by your doctor. This will allow the corticosteroid
- inhalation to better reach your lungs.
-
- SIDE EFFECTS
-
- Minor.
-
- Anxiety, dizziness, headache, flushing, irritability, insomnia, loss of
- appetite, muscle cramps, nausea, nervousness, restlessness, sweating,
- vomiting, weakness, or dryness or irritation of the mouth or throat (from the
- inhalation aerosol). These side effects should disappear as your body adjusts
- to the medication.
- To help prevent dryness and irritation of the mouth or throat, rinse your
- mouth with water after each dose of the inhalation aerosol.
- In order to avoid difficulty in falling asleep, check with your doctor to
- see if you can take the last dose of this medication several hours before
- bedtime each day.
- If you feel dizzy, sit or lie down for a while; get up from a sitting or
- lying position slowly.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- chest pain, difficult breathing, difficult or painful urination, palpitations,
- rash, or tremors.
-
- INTERACTIONS
-
- Metaproterenol interacts with several other types of medications:
- 1. Beta blockers (acebutolol, atenolol, betaxolol, carteolol, esmolol,
- labetalol, metoprolol, nadolol, penbutolol, pindolol, propranolol, timolol)
- antagonize (act against) this medication, decreasing its effectiveness.
- 2. Monoamine oxidase (MAO) inhibitors, tricyclic antidepressants,
- antihistamines, levothyroxine, and over-the-counter (nonprescription) cough,
- cold, allergy, asthma, diet, and sinus medications may increase the side
- effects of metaproterenol. At least 14 days should separate the use of this
- drug and the use of an MAO inhibitor.
- 3. There may be a change in the dosage requirements of insulin or oral
- antidiabetic medications when metaproterenol is started.
- 4. The blood-pressure-lowering effects of guanethidine may be decreased
- by this medication.
- 5. The use of metaproterenol with other bronchodilator drugs (either oral
- or inhaled) can have additive side effects. Discuss this with your doctor.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of the medications that are listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had,
- especially to metaproterenol or any related drug (such as albuterol,
- amphetamines, ephedrine, epinephrine, isoproterenol, norepinephrine,
- phenylephrine, phenylpropanolamine, pseudoephedrine, and terbutaline).
- * Tell your doctor if you now have or if you have ever had diabetes,
- glaucoma, high blood pressure, epilepsy, heart disease, enlarged prostate
- gland, or thyroid disease.
- * This medication can cause dizziness. Your ability to perform tasks
- that require alertness, such as driving a car or operating potentially
- dangerous machinery, may be decreased. Appropriate caution should, therefore,
- be taken.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking this medication.
- * Do not exceed the recommended dosage of this medication. Excessive use
- may lead to an increase in side effects or a loss of effectiveness.
- * Try to avoid contact of the aerosol with your eyes.
- * Do not puncture, break, or burn the aerosol container. The contents
- are under pressure and may explode.
- * Contact your doctor if you do not respond to the usual dose of this
- medication. It may be a sign of worsening asthma, which may require
- additional therapy.
- * Be sure to tell your doctor if you are pregnant. The effects of this
- medication during pregnancy have not been thoroughly studied in humans. Also,
- tell your doctor if you are breast-feeding an infant. It is not known whether
- this drug passes into breast milk.
