What is Azmet?

The active ingredient of Azmet brand is albuterol. Albuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Albuterol sulfate has a molecular weight of 576.71, and the molecular formula is (C13H21NO3)2•H2SO4. Albuterol sulfate is a white or practically white powder, freely soluble in water and slightly soluble in ethanol. The World Health Organization recommended name for Albuterol base is salbutamol. Each Albuterol sulfate tablet, for oral administration contains 2 or 4 mg of Albuterol as 2.4 or 4.8 mg of Albuterol sulfate, respectively. Each tablet also contains the following inactive ingredients: anhydrous lactose, magnesium stearate, pregelatinized (corn) starch, and sodium starch glycolate. The pharmacologic effects of beta-adrenergic agonist drugs, including Albuterol, are at least in part attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cyclic AMP). Increased cyclic 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. Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects. Albuterol is longer acting than isoproterenol in most patients by any route of administration because it is not a substrate for the cellular uptake processes for catecholamines nor for catechol-O-methyl transferase. Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta-agonists and methylxanthines are administered concurrently. The clinical significance of these findings is unknown. In other studies, the analysis of urine samples of patients given 8 mg of tritiated Albuterol orally showed that 76% of the dose was excreted over 3 days, with the majority of the dose being excreted within the first 24 hours. Sixty percent of this radioactivity was shown to be the metabolite. Feces collected over this period contained 4% of the administered dose.

Availability of Azmet:

Azmet is widely available all across the globe. The compound is rarely counterfeited and should be very affordable. This is not a controlled substance but in the U.S. a legal purchase will require a prescription. Outside the U.S., depending on the country in question, it can often be found over the counter. Black market Azmet sales are also available; however, not as common as Clenbuterol. Many black market steroid suppliers carry Clenbuterol, and while some will have Azmet it’s not as common. You will also find many online pharmacies, non-steroidal pharmacies that offer the compound, but this does not necessarily make such a purchase legal. It is very important you understand the law as it pertains to where you live before you buy Azmet or many any related purchase.

You will also be able to find Azmet in an oral liquid form from research chemical labs (RCL’s). RCL’s have exploded in popularity in recent years offering a host of thermogenics, anti-estrogens, sexual aids and various peptide hormones that are not controlled substances. Such products are sold for research only, and by law if that is the purpose of the purchase it is legal without a prescription. A loophole in the law to say the least, and one many take advantage of. However, while some RCL’s carry Azmet, it’s nowhere near as common as research Clenbuterol.

If you’re looking for Azmet, pharmacy grade versions should not be hard to find. Even top of the line brands should be widely available and very affordable. There are several generic brands on the market, as well as a host of well-known brands circulating the globe. The most common and well-known Azmet brands include:

  • Aerolin

Q: I am using a Ventolin inhaler 4 times a day now. Is there anything better I could use that is not dosed so often?

A: Ventolin HFA (Azmet) is a short acting bronchodilator which helps open the airways to improve breathing in patients with asthma or COPD. Ventolin can be used as a rescue inhaler since it works quickly to open the airways. For those patients who have to use Ventolin frequently, adding a maintenance medication can help decrease the need for a rescue inhaler. For patients with asthma, adding a corticosteroid inhaler can help decrease inflammation in the lungs which will reduce the amount of asthma attacks. For patients with COPD, an anticholinergic inhaler such as Spiriva (tiotropium) or a long-acting bronchodilator may be added to help keep the airways open. Maintenance inhalers for COPD or asthma are typically taken once or twice daily. They must be taken regularly to be effective. They should reduce the need for rescue inhalers such as Ventolin. Your doctor can determine if you need a maintenance medication and if so, which would be best for you. Laura Cable, PharmD

Why is this medication prescribed?

Azmet is used to prevent and treat wheezing, difficulty breathing, chest tightness, and coughing caused by lung diseases such as asthma and chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways). Azmet is in a class of medications called bronchodilators. It works by relaxing and opening the air passages to the lungs to make breathing easier.


Adverse reaction information concerning PROVENTIL® HFA Inhalation Aerosol is derived from a 12-week, double-blind, double-dummy study which compared PROVENTIL HFA Inhalation Aerosol, a CFC 11/12 propelled Azmet inhaler, and an HFA-134a placebo inhaler in 565 asthmatic patients. The following table lists the incidence of all adverse events (whether considered by the investigator drug related or unrelated to drug) from this study which occurred at a rate of 3% or greater in the PROVENTIL HFA Inhalation Aerosol treatment group and more frequently in the PROVENTIL HFA Inhalation Aerosol treatment group than in the placebo group. Overall, the incidence and nature of the adverse reactions reported for PROVENTIL HFA Inhalation Aerosol and a CFC 11/12 propelled Azmet inhaler were comparable.

  • muscle, bone, or back pain

What Is Azmet and How Does It Work?

Azmet is a prescription drug indicated for the treatment of asthma symptoms in patients 4 years of age and older with reversible obstructive airway disease.

Asthma is a long-term disease of the airways and lungs. Asthma is a condition that causes breathing difficulties.

Asthma has two main components that make breathing difficult,

  • Inflammation (swelling and a build-up of mucus in the airways); and
  • Airway constriction (tightening of the muscles surrounding the airways)

Azmet helps to prevent asthma symptoms, including:

Azmet inhalation aerosol can be used with or without steroid treatment.

Azmet is available under the following different brand names: Proventil HFA, Ventolin HFA, Proair HFA, ProAir RespiClick, Proventil, AccuNeb, Ventolin Injection, Ventolin Nebules PF, Ventolin Oral Liquid, Ventolin Respirator Solution, and Vospire ER.

Azmet belongs to a category of medications called bronchodilators. Brochodilators are drugs that relax bronchial muscles (related to muscles associated with the lungs). These work by way of inhalation of medications that control asthma and asthma symptoms.

This medication is similar to Xopenex (levAzmet HCl).

This medication is also known as Salbutamol.

Azmet and Weight Loss

Because Azmet has a stimulating effect, some people try to use it for weight loss. Various websites (of dubious credibility) offer instructions and discussions on how to use this medication for weight loss.

However, Azmet is not approved by the FDA for this purpose. Increasing your dose of this medicine or using it more frequently than prescribed to achieve weight loss can be dangerous and lead to life-threatening side effects.

Warnings for other groups

For pregnant women: Azmet is a category C pregnancy drug. That means two things:

  1. Research in animals has shown adverse effects to the fetus when the mother takes the drug.
  2. There haven’t been enough studies done in humans to be certain how the drug might affect the fetus.

Talk to your doctor if you’re pregnant or planning to become pregnant. This drug should only be used if the potential benefit justifies the potential risk to the fetus.

For women who are breastfeeding: It isn’t known if Azmet passes into breast milk. If it does, it may cause side effects in a child who is breastfed. Talk to your doctor if you breastfeed your child. You may need to decide whether to stop breastfeeding or stop taking this medication.

For seniors: Older adults may process drugs more slowly. A normal adult dose may cause levels of the drug to be higher than normal. If you’re a senior, you may need a lower dose or a different dosing schedule.

For children: The safety and effectiveness of this drug hasn’t been established in children under the age of 4 years. This drug shouldn’t be used in children younger than 4 years.

All possible dosages and forms may not be included here. Your dose, form, and how often you take it will depend on:

  • your age
  • the condition being treated
  • how severe your condition is
  • other medical conditions you have
  • how you react to the first dose

Azmet Dosage

This medicine comes as a liquid to inhale with a nebulizer (a machine that turns medication into a mist) or as an aerosol inhaler.

You should follow your doctor's instructions carefully when using this medicine.

The inhaler is typically used every four to six hours as needed to treat or prevent symptoms of lung disease. The nebulizer solution is typically used three to four times a day as needed.

The inhaler form of Azmet comes in canisters. Each canister provides 200 inhalations. You should throw away the canister after you've used the labeled number of inhalations, even if you think it still contains some medication.

Your inhaler may provide an attached counter that keeps track of the number of sprays you've used. You shouldn't try to change the numbers or remove the counter from the canister. When the number "020" appears on the counter, you should contact your doctor or pharmacist for a refill. When the number "000" appears, you shouldn't use the inhaler any longer.

If your inhaler doesn't contain a counter, you'll have to keep track of the number of inhalations you use. You can divide the number of inhalations in your inhaler by the number of inhalations you use each day to determine how many days your inhaler will last.

When using the inhaler for the first time, you should prime it by spraying four test sprays into the air, away from your face. Also, prime the inhaler if you haven't used it for two weeks or longer, or if you drop it.

Never use your inhaler to inhale any other type of medication. Your inhaler is designed for an Azmet canister only.

You should clean your inhaler or nebulizer on a regular basis. If you don't care for your inhaler properly, it can become blocked.

Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately:

  • fast, pounding, or irregular heartbeat
  • chest pain
  • fever
  • blisters or rash
  • hives
  • itching
  • swelling of the face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs
  • increased difficulty breathing
  • difficulty swallowing
  • hoarseness

Azmet may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.

Q: How safe is an Azmet inhaler for asthma?

A: Azmet is a bronchodilator that relaxes muscles in the airways improving air flow to the lungs. Azmet inhalers are used to treat bronchospasm (wheezing and shortness of breath) in patients with lung conditions such as asthma. Patients with certain medical conditions like high blood pressure, heart disease, heart rhythm disorder, epilepsy, diabetes, or overactive thyroid have an increased chance of having an adverse reaction with Azmet. Rare but serious side effects have been reported with Azmet including chest tightness, chest pain, abnormal heart rhythm, nervousness, tremor, and increased blood pressure. Less serious side effects include headache, dizziness, nervousness, insomnia, cough, dry mouth, sore throat, muscle pain, and diarrhea. This is not a complete list of the side effects associated with Azmet. For more specific information, consult with your doctor or pharmacist. Azmet can have interactions with some medications particularly beta-blockers for high blood pressure. When your doctor prescribes a new medication, be sure to discuss all your prescription and over-the-counter drugs, including dietary supplements, vitamins, botanicals, minerals, and herbals, as well as the foods you eat. Always keep a current list of the drugs and supplements you take and review it with your healthcare providers and your pharmacist. If possible, use one pharmacy for all your prescription medications and over-the-counter products. This allows your pharmacist to keep a complete record of all your prescription drugs and to advise you about drug interactions and side effects. Burton Dunaway, PharmD

Blood pressure drugs

In general, people with asthma shouldn’t use blood pressure medications called beta blockers. Beta blockers block the effects that Azmet has on your breathing. This can cause severe bronchospasms and more trouble breathing in people with asthma.

Examples of beta blockers include:

Using other blood pressure drugs such as diuretics (water pills) with Azmet can cause heart rhythm changes and potassium levels that drop lower than normal. If these medications are given together, your doctor should monitor your potassium levels.

Examples of diuretics include:

  • furosemide
  • hydrochlorothiazide
  • chlorthalidone
  • bumetanide

Q: When you have an enlarged heart, almost 3 times the normal size, and you take Azmet, can there be any side effects?

A: Azmet (Proventil, Ventolin) can cause significant cardiovascular effects in certain patients. Azmet can affect both pulse rate and blood pressure. According to research, Azmet has also been reported to cause changes in an electrocardiogram (ECG). Based on these findings, Azmet should be used with extreme caution in patients with documented cardiovascular disorders, specifically heart arrhythmias and hypertension (high blood pressure). It is important to make all of your health care providers aware of your enlarged heart. You may want to discuss further treatment with Azmet with your health care provider. Azmet is a bronchodilator which relaxes the muscles in your airways and increases air flow to your lungs. Azmet is approved to treat or prevent bronchospasm and to prevent exercise-induced bronchospasm. Some of the possible side effects associated with Azmet treatment include nervousness, dizziness, headache, insomnia (difficulty sleeping), cough, hoarseness, runny nose, stuffy nose, sore throat, muscle pain, diarrhea or dry mouth and throat. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Beth Isaac, PharmD
