Xopenex vs Atrovent
Introduction
For patients with chronic obstructive pulmonary disease (COPD) or asthma, it's crucial to manage symptoms and improve respiratory function. Xopenex and Atrovent are two types of medication often prescribed for these conditions. They impact different components in the body but both aim to promote easier breathing in patients with respiratory disorders. Xopenex is a short-acting beta2-adrenergic agonist (SABA), targeting the smooth muscle around air passages to relax them and improve airflow, while Atrovent is an anticholinergic bronchodilator that works by blocking acetylcholine receptors in bronchial muscles, causing them to dilate which increases the volume of airflow into the lungs.
What is Xopenex?
Levalbuterol (the generic name for Xopenex) was a substantial development in the class of bronchodilators known as short-acting beta2-agonists (SABAs). It received FDA approval in 1999. Xopenex works by relaxing and opening air passages to the lungs, helping to alleviate symptoms such as wheezing and shortness of breath. The drug is frequently prescribed for conditions like asthma or chronic obstructive pulmonary disease (COPD).
On the other hand, Ipratropium bromide (Atrovent), an anticholinergic bronchodilator approved by the FDA well before Levalbuterol, operates differently. Atrovent inhibits reflexes that cause constriction of your airways, thereby reducing bronchospasm.
Xopenex selectively influences beta2 receptors found predominantly in lung tissue with minor influence on heart rate or blood sugar levels - this results in it having fewer side effects than other bronchodilators that have stronger systemic effects.
What conditions is Xopenex approved to treat?
Xopenex is approved for the treatment of various respiratory conditions:
- Acute episodes of bronchospasm or prevention of asthmatic symptoms
- Management and prevention of chronic obstructive pulmonary disease (COPD)-related bronchospasms in patients aged 6 years and older.
Atrovent, on the other hand, has a broader application:
- Maintenance treatment for bronchospasm associated with COPD including chronic bronchitis and emphysema
- Treatment as an adjunct to beta-adrenergic agonists in asthma management.
How does Xopenex help with these illnesses?
Xopenex helps to manage respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD) by relaxing the muscles in the airways and increasing airflow to the lungs. It does this by stimulating beta-2 adrenergic receptors, which leads to bronchodilation, or widening of the air passages. Beta-2 adrenergic receptors are part of your sympathetic nervous system, a network that controls various automatic bodily functions including heart rate, blood pressure, and breathing patterns among others. In individuals with respiratory conditions like asthma or COPD, their airways can become constricted making it difficult for them to breathe properly. Therefore, by stimulating these receptors and causing bronchodilation, Xopenex can limit the negative effects of these respiratory conditions and help patients manage their condition and stabilize their breathing.
What is Atrovent?
Atrovent is a brand name for ipratropium, which is an anticholinergic bronchodilator. It works by blocking the action of acetylcholine at muscarinic receptors in the lung airways, leading to dilation or widening of the airways. This can help to alleviate symptoms such as shortness of breath and wheezing associated with conditions like chronic obstructive pulmonary disease (COPD) and asthma. Ipratropium was first approved by the FDA in 1986. As it does not act on beta-2 adrenergic receptors like some other bronchodilators, its side-effect profile is different than that of drugs such as Xopenex (levalbuterol), especially in terms of causing less potential for rapid heart rate and jitteriness, common side effects with beta agonist medications. The effects on muscarinic receptors can be beneficial for patients who do not respond well to typical beta-2 adrenergic receptor agonists like levalbuterol.
What conditions is Atrovent approved to treat?
Atrovent has been approved for the treatment of:
- Chronic obstructive pulmonary disease (COPD)
- Bronchospasm associated with COPD
- Rhinorrhea associated with allergies and colds
It's worth mentioning that Atrovent is a bronchodilator, which works by relaxing muscles in the airways to improve breathing. It's often used as a maintenance medication and not intended for treating sudden breathing problems.
How does Atrovent help with these illnesses?
Atrovent, or ipratropium bromide, is a bronchodilator that functions by relaxing the muscles in your airways and increasing airflow to your lungs. It plays an essential role in managing chronic obstructive pulmonary disease (COPD) including chronic bronchitis and emphysema. Atrovent works by blocking acetylcholine activity on smooth muscle cells and submucosal glands in the lung, thus reducing constriction and mucus production respectively. This makes it effective for patients who do not respond adequately to "typical" beta2-agonist medications like Xopenex (levalbuterol). Moreover, due to its different mechanism of action, Atrovent can be combined with beta2-agonists for more comprehensive management of COPD symptoms.
How effective are both Xopenex and Atrovent?
Both levalbuterol (Xopenex) and ipratropium bromide (Atrovent) have established histories of success in treating patients with obstructive airway diseases such as asthma or chronic obstructive pulmonary disease (COPD), although they were approved by the FDA more than a decade apart. Since they act on different receptors in the lungs, they may be prescribed under different circumstances. The effectiveness of Xopenex and Atrovent in alleviating symptoms associated with COPD was directly studied in a double-blind clinical trial; both drugs exhibited similar efficacy in improving lung function but showed differences favoring Xopenex for certain patient-reported outcomes related to quality of life.
A 2004 review of meta-analysis reports on levalbuterol demonstrated that it is effective from the first dose at reducing symptoms associated with acute asthma exacerbations, has favorable side effect profiles compared to other bronchodilators and is well-tolerated even across varying age groups. Further, as one of the newer generation selective beta2-agonists developed, there is significant research demonstrating its effectiveness.
A 2016 review and meta-analysis indicated that Atrovent seems to improve lung function more effectively than placebo for individuals suffering from COPD, showing similar efficacy to other common bronchodilators. Nonetheless, Atrovent's use typically considers co-prescription alongside other first-line treatments like beta2-agonists or corticosteroids so data confirming its efficacy as a stand-alone treatment is less robust. However due to its unique pharmacology acting on muscarinic receptors leading to bronchial smooth muscle relaxation, Atrovent could be an optimal choice for patients who did not respond well to beta2-agonists or those prone needing additional symptom control.
At what dose is Xopenex typically prescribed?
Inhaled dosages of Xopenex range from 0.31-0.63 mg three times per day, but studies have indicated that a dosage as low as 0.31 mg three times per day can be effective for treating bronchospasm in most people. Children aged 6 to 11 years may start with a dose of 0.31 mg three times daily, while children under six should follow the doctor's prescription carefully. In both populations, the dosage can be increased after some weeks if there is no response or improvement in symptoms. However, this increase should only happen under medical supervision and the maximum recommended dose of Xopenex (1.25 mg) should not be exceeded within any four-hour period.

At what dose is Atrovent typically prescribed?
Atrovent treatment is typically initiated with a dosage of 2 puffs (42 mcg/puff), four times daily. For maintenance therapy, this dose can be increased to a maximum of 4 puffs at a time, but should not exceed 12 inhalations in 24 hours. This medication takes effect within minutes and lasts for up to six hours, providing long-lasting relief from bronchospasm symptoms associated with chronic obstructive pulmonary disease (COPD). If no significant improvement is observed after using Atrovent regularly for one week, consult your healthcare provider as they may need to reassess the treatment plan.
What are the most common side effects for Xopenex?
Common side effects between Xopenex (levalbuterol) and Atrovent (ipratropium bromide) differ somewhat due to their different active ingredients. Users of both medications may experience:
- Nervousness
- Dizziness or lightheadedness
- Headache
- Dry mouth
- Coughing, hoarseness, throat irritation or sore throat
- Nausea, vomiting or stomach upset
- Palpitations (feeling your heartbeat)
With Xopenex specifically, some people might also encounter:
- Increased heart rate
- Shaking hands/tremors
While those taking Atrovent might notice:
- Difficulty urinating
- Blurred vision
Always remember to seek medical advice if any new symptoms arise while taking either medication.
Are there any potential serious side effects for Xopenex?
While Xopenex and Atrovent are both used to manage symptoms of respiratory conditions, they can have different side effects. Serious adverse reactions from Xopenex may include:
- Worsening breathing problems or bronchospasm: coughing, wheezing, feeling short of breath
- Signs of an allergic reaction: rash; hives; itching; red, swollen, blistered or peeling skin with or without fever; wheezing; chest tightness or trouble breathing in general
- Heart-related issues like irregular heartbeat (fast/pounding), fluttering in your chest and sudden dizziness as if you might pass out.
- Eye problems including blurred vision, eye pain/swelling/redness, seeing halos around lights
- Low potassium levels - muscle weakness/cramps/twitches
Atrovent also has possible serious side effects such as:
- Allergic reactions like skin rash/hives/itching/swelling especially of the face/lips/tongue/throat leading to severe dizziness/trouble breathing
- Difficulty urinating or inability to urinate at all
If you experience any unusual health changes while using these medications it's important that you immediately consult your healthcare provider.
What are the most common side effects for Atrovent?
Potential side effects of Atrovent include:
- Dry mouth, hoarseness or throat irritation
- Headache, dizziness
- Blurred vision
- Nausea or upset stomach
- Difficulty urinating
- Cough or cold symptoms such as stuffy nose, sneezing, and sore throat. Remember that not everyone experiences these side effects and they usually subside with time. However, if any persist or worsen, it's important to seek medical attention promptly.
Are there any potential serious side effects for Atrovent?
Atrovent, like all medication, can cause side effects. While many people do not experience any or only minor side effects, it's important to be aware of the potential for serious reactions. If you notice any signs of an allergic reaction such as hives; difficulty breathing; swelling in your face, lips, tongue or throat after using Atrovent contact your doctor immediately. Other severe symptoms may include bronchospasm (wheezing or chest tightness), eye pain and seeing halos around lights due to increased pressure in the eyes (a sign of glaucoma), painful urination or difficulty passing urine which could indicate a bladder obstruction and irregular heart beat. Changes in behavior are very rare but if you feel unusually agitated or restless while taking Atrovent consult your healthcare provider without delay.
Contraindications for Xopenex and Atrovent?
Similarly, both Xopenex and Atrovent, as with other bronchodilators, may exacerbate symptoms in some individuals. If you notice worsening of your breathing problems or an increase in wheezing after using these medications, please seek immediate medical attention.
Neither Xopenex nor Atrovent should be used if you are allergic to levalbuterol or ipratropium bromide respectively. Always inform your healthcare provider about the medications you are taking; this includes prescription drugs, over-the-counter medicine and herbal supplements.
Xopenex is not typically recommended for use within six hours of taking other short-acting beta2-agonists while Atrovent can interact with antihistamines, antidepressants and certain heart disease drugs leading potentially serious effects. Your doctor will need to carefully manage your medication regimen to prevent dangerous interactions between Xopenex or Atrovent and the various other medicines that might be prescribed alongside them.
How much do Xopenex and Atrovent cost?
Considering the brand name versions of these drugs:
- The price of 30 Xopenex HFA inhalers (45 mcg) averages around $70, which works out to approximately $2.3 per day when used thrice daily.
- The cost for one Atrovent HFA inhaler (17 mcg) is about $400, working out to roughly $13/day if used three times a day.
Thus, if you are using an inhaler three times daily or more frequently, then brand-name Xopenex is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For generic versions of Xopenex (levalbuterol) and Atrovent (ipratropium), costs are significantly lower:
- Levalbuterol hfa (45 mcg) costs about $50 for one inhaler with approximate costs falling between $1.6 and $5 per day depending upon frequency.
- Ipratropium bromide hfa can be purchased at around $30-$60 per unit offering a reduced rate ranging from as low as just over a dollar ($1+) up to approximately four dollars ($4) each day based on usage.
Popularity of Xopenex and Atrovent
Levalbuterol, available under the brand name Xopenex, was prescribed to approximately 1.2 million people in the USA in 2020. Levalbuterol accounted for just over 8% of all beta-agonist prescriptions in the US and is commonly used as a rescue inhaler to treat symptoms of asthma and chronic obstructive pulmonary disease (COPD). The prescription rate of levalbuterol has been steady since its introduction into the market.
On the other hand, ipratropium bromide, marketed under brands like Atrovent, was prescribed to around 3 million patients in the USA during that same year. Ipratropium bromide accounts for nearly 20% of anticholinergic bronchodilator prescriptions across the country. This medication is specifically designed to open up airways and assist with easier breathing among those suffering from conditions such as COPD and asthma. Usage of this drug has also remained relatively stable over recent years.
Conclusion
Both Xopenex (levalbuterol) and Atrovent (ipratropium bromide) are commonly used in patients with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). They have been well-studied, and clinical trials indicate that they are more effective than placebo treatments. Sometimes, these drugs may be combined for a synergistic effect, but this should only be done under the supervision of a healthcare provider due to possible contraindications.
They work differently: Xopenex is a short-acting beta2-adrenergic agonist that relaxes the muscles around the airways in your lungs making it easier to breathe while Atrovent is an anticholinergic bronchodilator that works by blocking certain reflexes in the lungs which cause spasms of the airways.
Xopenex tends to be used as a rescue medication during acute episodes, whereas Atrovent is mainly considered for maintenance therapy. Both medications are available generically which can represent significant cost savings especially for those who need to pay out of pocket.
The onset of action could vary between these two medications; effects from Xopenex can typically be felt within 15 minutes while it might take up to 30 minutes before noticing improvements with Atrovent.
While both drugs share similar side effect profiles including headache, dizziness, dry mouth and coughing, they're generally well-tolerated. However, one notable difference would be heart palpitations being less common with Atrovent compared to Xopenex. It's crucial that patients monitor their symptoms closely when starting on either treatment and seek medical help if breathlessness worsens suddenly or significantly.
