Spiriva vs Advair
Introduction
For patients with chronic obstructive pulmonary disease (COPD) or asthma, certain medications that target and relax the muscles around the airways can help in reducing symptoms and improving lung function. Spiriva and Advair are two such drugs frequently prescribed for these conditions. They each impact different aspects of respiratory physiology, but both have effects that improve breathing in patients with COPD or asthma. Spiriva is an anticholinergic bronchodilator which works by relaxing and opening up the airways to the lungs, making it easier to breathe. On the other hand, Advair is a combination medication consisting of fluticasone propionate (a corticosteroid) and salmeterol (a long-acting beta-2 agonist). These components work together to reduce inflammation within the lungs while also keeping your air passages open.
What is Spiriva?
Tiotropium (the generic name for Spiriva) is an anticholinergic bronchodilator, a different class of drugs than the LABA/ICS combination found in fluticasone/salmeterol (Advair). Tiotropium was first approved by the FDA in 2004. Similar to Prozac's function with serotonin, Spiriva works by blocking acetylcholine on smooth muscles surrounding the bronchi, preventing these muscles from constricting and allowing for more open airways in patients with chronic obstructive pulmonary disease (COPD) or asthma. Its primary effect is on muscarinic receptors without having significant effects on other types of receptors which results in fewer side effects. On the other hand, Advair combines two medications: fluticasone propionate, a corticosteroid that reduces inflammation; and salmeterol xinafoate, a long-acting beta2-adrenergic receptor agonist which relaxes the smooth muscle around airways to prevent sudden breathing problems.
What conditions is Spiriva approved to treat?
Spiriva is approved for the treatment of different respiratory conditions:
- Chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema
- Asthma in adults and adolescents aged 12 years and older
- Reduction of COPD exacerbations, or worsening symptoms.
How does Spiriva help with these illnesses?
Spiriva works to manage chronic obstructive pulmonary disease (COPD) and asthma by increasing the amount of bronchodilation in the lungs. It does this by blocking a type of receptor called muscarinic receptors, which when activated can cause airway constriction and mucus production. By inhibiting these receptors, Spiriva ensures that the airways remain relaxed and open for longer periods of time. This not only alleviates symptoms such as shortness of breath, but also makes it easier for patients to breathe normally throughout their day-to-day activities.
Acetylcholine is a neurotransmitter that binds to muscarinic receptors, causing contraction of smooth muscle tissues found within the lung’s airways leading to narrowing or obstruction. Individuals with COPD or asthma have chronically narrow or obstructed airways due to inflammation. Therefore, by inhibiting acetylcholine's effects on these muscles via its actions on muscarinic receptors, Spiriva helps alleviate respiratory distress associated with these conditions while promoting improved respiration.
What is Advair?
Advair is a brand name for a combination of fluticasone and salmeterol. Fluticasone is a corticosteroid that reduces inflammation, while salmeterol works as a long-acting beta agonist (LABA) which helps to relax muscles in the airways and enhance breathing. This duo-action contributes to its efficacy in managing both asthma and chronic obstructive pulmonary disease (COPD). It was first approved by the FDA in 2000. Unlike Spiriva, which is an anticholinergic bronchodilator acting mainly on muscarinic acetylcholine receptors to maintain open airways, Advair's dual action offers both anti-inflammatory properties and prolonged bronchodilation effects. Its side-effect profile differs from Spiriva with more common occurrences of throat irritation, hoarseness or voice changes due to its steroid component; however, it tends not to cause dry mouth frequently associated with anticholinergics like Spiriva. The combined effects of fluticasone and salmeterol may prove particularly beneficial for patients who require consistent control over their respiratory conditions where single-agent therapy such as Spiriva might be insufficient.
What conditions is Advair approved to treat?
Advair is a popular medication that has been approved for use in the treatment of:
- Chronic Obstructive Pulmonary Disease (COPD), which includes chronic bronchitis, emphysema, or both
- Asthma in patients aged 12 years and older. Remember that Advair won't replace a rescue inhaler for sudden symptoms and should not be used more than twice daily.
How does Advair help with these illnesses?
Advair is a combination medication used in the management of asthma and chronic obstructive pulmonary disease (COPD). It contains fluticasone, a corticosteroid that reduces inflammation, and salmeterol, a long-acting beta agonist (LABA) that relaxes muscles in the airways to improve breathing. This dual action helps control and prevent symptoms such as wheezing and shortness of breath. Unlike Spiriva which primarily works by relaxing muscles in the airways to help keep them open, Advair not only relaxes these muscles but also decreases inflammation in the lungs. Its action on both fronts may play roles in its effectiveness for patients with persistent or severe respiratory conditions. Hence it might be prescribed when a patient does not respond well to 'typical' bronchodilators such as Spiriva, or it can be combined with other medications for better efficacy.
How effective are both Spiriva and Advair?
Both tiotropium (Spiriva) and fluticasone/salmeterol (Advair) have demonstrated effectiveness in managing symptoms of chronic obstructive pulmonary disease (COPD), and they received FDA approval within a few years of each other. Since they act on different aspects of the disease, their prescriptions may depend on specific patient needs. The efficacy of Spiriva and Advair was directly compared in several double-blind clinical trials; both drugs showed similar capabilities in controlling COPD symptoms with promising safety profiles.
In terms of usage, a 2010 review indicated that Spiriva starts showing noticeable improvements from the first week onwards, reducing exacerbations and improving lung function more effectively than most bronchodilators alone. It has been well-tolerated across age groups including elderly populations who often have comorbid conditions. As it is an anticholinergic agent, there are significant studies supporting its effectiveness in treating COPD, with an optimal dose considered to be 18 mcg/day.
A meta-analysis conducted in 2017 revealed that Advair seems to reduce exacerbations more efficiently than placebos or single-agent long-acting bronchodilators due to its dual-action mechanism – fluticasone as a corticosteroid reduces inflammation while salmeterol opens airways making breathing easier for patients with COPD. However, it's usually reserved for severe cases or when initial treatments don't yield desired results due to higher risk associated with side effects such as pneumonia. Substantial research involves using Advair alongside other first-line treatments rather than standalone therapy leading to less robust data confirming its independent efficacy compared to that for Spiriva.
At what dose is Spiriva typically prescribed?
Inhaled doses of Spiriva (Tiotropium bromide) range from 2.5–5 mcg/day, delivered via Respimat inhaler once daily. Studies have indicated that this is effective for managing chronic obstructive pulmonary disease (COPD) and asthma in most people above the age of six years old. With Advair (Fluticasone propionate/Salmeterol), dosages vary depending on the condition being treated, but can range from 100-500 mcg Fluticasone with 50 mcg Salmeterol twice a day for adults and children over four years old for asthma management; or 250/50 mcg dose twice per day approximately 12 hours apart for adults with COPD. Dosage adjustments may be made based on individual response to treatment, but should not exceed recommended amounts under any circumstances.

At what dose is Advair typically prescribed?
Advair treatment typically begins with one inhalation (either 100/50, 250/50, or 500/50 micrograms of fluticasone propionate/salmeterol) twice a day, spaced approximately 12 hours apart. The specific initial dosage depends on the severity of the patient's asthma or COPD. If symptoms do not improve after a few weeks at this level, your doctor may increase your dose to two inhalations twice daily. The maximum recommended dose is two inhalations of Advair Diskus 500/50 mcg twice daily. As always, it's important to follow your healthcare provider’s instructions and not exceed their prescribed dosage.

It's important to understand that these medications can affect individuals differently. Always consult a healthcare provider before deciding on medication.
Are there any potential serious side effects for Spiriva?
While both Spiriva and Advair are used to manage chronic obstructive pulmonary disease (COPD), they may cause different side effects. Not everyone will experience these, but it's important to be aware of potential issues:
- With Spiriva, some people may have an allergic reaction that could include hives, difficulty breathing or swallowing, swelling in the face or throat.
- There is a possibility of experiencing blurred vision or eye pain. If this occurs suddenly or persists for an extended period of time, seek immediate medical attention.
- Both medications can potentially affect heart rate — leading to fast or pounding heartbeats and feelings like you might pass out — although this is rarer with Spiriva than with Advair.
- Some people using these medications have reported feeling unsteady due to lower sodium levels in their body; symptoms include headache, confusion and severe weakness among others.
- A very serious side effect that has been associated particularly with Advair use includes muscle stiffness and twitching which should prompt immediate medical care.
Always remember if any unusual symptoms occur after starting either medication contact your healthcare provider immediately. They can help determine whether the symptom is a side effect of the drug or something else.
What are the most common side effects for Advair?
The use of Advair can result in the following side effects:
- Throat irritation and hoarseness
- Headaches
- Muscle and bone pain
- Nausea and vomiting
- Respiratory tract infections, such as bronchitis or sinusitis
- Rapid heart rate (tachycardia)
- Sleep problems due to restlessness or nervousness
- Blurred vision, which could indicate an eye condition called glaucoma
- Tremors or shakiness
- Skin rash or hives.
Remember that it's always important to discuss any concerning symptoms with your healthcare provider while on medication.
Are there any potential serious side effects for Advair?
Although Advair is generally well-tolerated, it may cause some serious side effects in rare cases. These could include:
- Signs of an allergic reaction such as skin rash, severe itching, facial or throat swelling and difficulty breathing
- An unexpected increase in wheezing right after using the medication
- Chest pain or irregular heartbeats
- Nervousness and trembling
- Vision problems like blurred vision, eye pain or red eyes
- High blood sugar levels which can lead to increased thirst, urination and hunger
- Behavioral changes including restlessness, depression or suicidal thoughts
Should you experience any of these symptoms while on Advair therapy, consult your healthcare provider immediately for further advice.
Contraindications for Spiriva and Advair?
Both Spiriva and Advair, along with most other medications for chronic obstructive pulmonary disease (COPD), may worsen symptoms in some people. If you notice an aggravation of your COPD symptoms or experience difficulty breathing, chest tightness, or wheezing, please seek immediate medical attention.
Spiriva and Advair should not be taken if you are currently taking certain types of medications such as beta-blockers. Always tell your physician which medications you're on; beta-blockers will require a period to clear from the system to prevent dangerous interactions with Spiriva and Advair. Beta-blockers can cause bronchospasm in patients with asthma or COPD so these medicines should ideally not be used together unless directed by a healthcare professional.
How much do Spiriva and Advair cost?
For the brand name versions of these drugs:
- The price of 30 capsules of Spiriva (18 mcg) averages around $470, which works out to approximately $15/day.
- The price for a pack of Advair Diskus (100/50 mcg) is about $400, and this works out to roughly $13/day given that one pack typically lasts for 30 days.
Thus, if you are considering both options for maintaining control over COPD or asthma symptoms, then brand-name Advair Diskus may be less expensive on a per-day treatment basis. It's essential to remember that cost should not be your primary consideration when determining which medication is right for you – effectiveness and side effects matter too.
As far as generic versions go:
- Currently in the U.S., there isn't an FDA-approved generic equivalent available for either Spiriva (tiotropium bromide) or Advair (fluticasone propionate/salmeterol), so costs remain relatively high compared with other medications where generics are available.
Popularity of Spiriva and Advair
Tiotropium, sold under the brand name Spiriva among others, was estimated to have been prescribed to around 4.2 million people in the US in 2020. This long-acting bronchodilator is used for maintenance treatment of chronic obstructive pulmonary disease (COPD), including bronchitis and emphysema. It accounted for just over 10% of COPD prescriptions in the US but has been generally increasing in prevalence since its introduction.
Fluticasone/Salmeterol, known by the brand name Advair among others, was prescribed to approximately 3.5 million people in the USA during that same period. In terms of asthma and COPD medication prescriptions within the US, it holds a significant share at around 8%. The use of this combination therapy which includes an inhaled corticosteroid and a long-acting beta agonist has remained relatively steady over recent years.
Conclusion
Both Spiriva (tiotropium) and Advair (fluticasone/salmeterol) have been widely used in the management of chronic obstructive pulmonary disease (COPD), with numerous clinical studies supporting their efficacy over placebo treatments. Sometimes, they can be combined to provide additional bronchodilation and anti-inflammatory effects, subject to careful consideration by a physician due to potential drug-drug interactions. Their mechanisms of action differ; Spiriva is an anticholinergic that prevents bronchoconstriction while Advair combines a corticosteroid (fluticasone), which reduces inflammation, and a long-acting beta agonist (salmeterol), which relaxes muscle airways.
Both medications are available as generics, providing cost savings for patients paying out of pocket. The adjustment period may apply for both drugs; noticeable improvement may not occur immediately after starting treatment.
Their side effect profiles are somewhat similar although different types of side effects dominate each medication. Both are generally well-tolerated but Spiriva might cause dry mouth more often while Advair could lead to thrush or pneumonia due to its immunosuppressive component fluticasone. Patients must monitor any changes in symptoms when beginning these treatments and seek immediate medical help if conditions like sudden breathing problems or worsening COPD symptoms occur.
