Spiriva vs Spiriva Respimat
Introduction
For patients with chronic obstructive pulmonary disease (COPD), including conditions like emphysema and chronic bronchitis, there are certain medications that can aid in managing symptoms and improving the quality of life. Spiriva and Spiriva Respimat are two such drugs often prescribed for COPD. They are both anticholinergics which work by relaxing the muscles around the airways to allow easier breathing but they differ in their delivery mechanisms.
Spiriva, known generically as tiotropium bromide, is traditionally delivered via a HandiHaler device where it's breathed in as a dry powder. On the other hand, Spiriva Respimat delivers tiotropium bromide through a slow-moving mist that helps more medicine get into your lungs. The choice between these two largely depends on personal comfort and ease of use for each individual patient.
What is Spiriva?
Tiotropium (the generic name for Spiriva) was a significant advancement in the field of bronchodilator medicines used to treat chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis. Tiotropium got its first approval by the FDA in 2004. Spiriva works by relaxing muscles in the airway, thus increasing airflow to your lungs over extended periods. It is usually prescribed for long-term maintenance treatment of COPD symptoms.
Spiriva Respimat is essentially an improved inhaler device delivering the same active ingredient as traditional Spiriva but in a mist form that's easier to inhale, especially for patients who might have difficulty with other inhalers. Both versions are designed to be used once daily; however, while regular Spiriva delivers this dose from one capsule via the HandiHaler device, Spiriva Respimat delivers it through two puffs from an inhaler. The side effects between both delivery methods are similar due to them containing the same medicine.
What conditions is Spiriva approved to treat?
Spiriva and Spiriva Respimat are both approved for the treatment of different respiratory conditions:
- Chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema
- Asthma in patients 6 years of age and older with a history of exacerbations, specifically using Spiriva Respimat Both forms serve to make breathing easier by relaxing muscles in the airways.
How does Spiriva help with these illnesses?
Spiriva and Spiriva Respimat both manage chronic obstructive pulmonary disease (COPD) by increasing the amount of tiotropium available in the lungs. Tiotropium is a bronchodilator that works by relaxing muscles in the airways to improve breathing. By blocking acetylcholine receptors, it prevents contraction of smooth muscle in airway walls, therefore widening the airways.
These medications differ primarily in their delivery mechanism. While Spiriva comes as a capsule taken using an inhalation device known as HandiHaler, Spiriva Respimat is delivered via a propellant-based soft-mist inhaler which produces slow-moving aerosol clouds lasting 1.5 seconds longer than standard inhalers and allowing patients more time to inhale their medication.
It's important for individuals with COPD to have efficient lung function so they can breathe easier and manage their condition better. Therefore, whether through SpiRiva or SpiRiva RespiMat, increasing titroprium levels can limit the negative effects of COPD and help patients maintain better control over their symptoms.
What is Spiriva Respimat?
Spiriva Respimat, also known as tiotropium bromide, is a long-acting bronchodilator. It works by relaxing the muscles in the airways and increasing airflow to the lungs. This medication comes in an innovative inhaler device that uses slow-moving mist to deliver the medicine into your lungs. The soft mist generated by Spiriva Respimat has been shown to penetrate deeper into the lung tissues compared to other traditional inhalers.
First approved by FDA in 2014, Spiriva Respimat is not a steroid; it does not inhibit any specific neurotransmitter reuptake or act as a receptor antagonist like certain antidepressants do. Its mechanism of action focuses on easing breathing problems associated with conditions such as chronic obstructive pulmonary disease (COPD), including bronchitis and emphysema.
Its side-effect profile differs from medications such as Prozac; instead of causing sedation or sexual dysfunction, common side effects can include dry mouth and upper respiratory tract infection. However, its effect on enhancing lung function can be beneficial especially for patients who struggle with typical COPD treatments.
What conditions is Spiriva Respimat approved to treat?
Spiriva Respimat is approved for the use in treating:
- Chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema
- Asthma in adults and adolescents aged 12 years or older
It's important to note that, unlike Spiriva HandiHaler, which delivers the medication through a dry powder inhaler, Spiriva Respimat delivers it as a slow-moving mist that makes it easier for some patients to inhale.
How does Spiriva Respimat help with these illnesses?
Spiriva Respimat, similar to Spiriva, is a type of medication known as an anticholinergic bronchodilator. It functions by blocking the action of acetylcholine in the body, which can reduce airway muscle contractions and thus improve respiratory function for patients suffering from conditions like chronic obstructive pulmonary disease (COPD). In contrast to standard Spiriva inhalers that deliver medications in dry powder form, Spiriva Respimat disperses medication as a slow-moving mist. This slower release offers an extended window for inhaling the drug and makes it easier for more of the medicine to reach smaller airways deep within the lungs. Therefore, while both forms are effective at treating COPD symptoms such as shortness of breath or wheezing, some may find using Spiriva Respimat easier than traditional Spiriva due to its unique delivery mechanism.
How effective are both Spiriva and Spiriva Respimat?
Both Spiriva HandiHaler (tiotropium bromide) and Spiriva Respimat, are established medications used in the management of chronic obstructive pulmonary disease (COPD), with Spiriva Respimat being approved by the FDA a few years after the HandiHaler. Both forms contain tiotropium bromide as their active ingredient and function by acting on muscarinic receptors in bronchial smooth muscle to promote airway dilation.
In direct comparisons between these two delivery systems for tiotropium, it was found that both exhibited similar efficacy in managing symptoms associated with COPD such as shortness of breath and wheezing. A 2014 study comparing these two products noted there were no significant differences in patient-reported outcomes or lung function tests [1].
A review published in 2013 reported that Spiriva has shown consistent effectiveness from the onset of treatment, demonstrating an ability to improve breathing capacity while also reducing exacerbations and hospitalizations due to COPD. The same study highlighted its favorable safety profile compared to other bronchodilators.
More recent studies suggest that Spiriva Respimat may provide some benefits over the HandiHaler device including delivering a more consistent dose regardless of inspiratory flow rates which can vary among patients with different degrees of airway obstruction [2]. However, each form may be preferred under different circumstances depending on factors such as patient's preference and ability to use each inhaler correctly.

At what dose is Spiriva typically prescribed?
Inhalation dosages of Spiriva and Spiriva Respimat are prescribed differently. For the treatment of COPD including chronic bronchitis and emphysema, adults should inhale the contents of one Spiriva capsule (18 mcg) once a day using the HandiHaler device. On the other hand, with Spiriva Respimat, adults are recommended to inhale two puffs (5 mcg each puff for a total dose of 10 mcg) once daily. The medication should not be used more than once in 24 hours. This treatment is typically suitable for adolescents aged over 18 years old; however, usage and dosage in children or adolescents should always be determined by a doctor.

At what dose is Spiriva Respimat typically prescribed?
Spiriva Respimat treatment is usually initiated at a dosage of 2.5 mcg per actuation, inhaled orally once daily. The maintenance dose remains consistent; there's no requirement to increase the dosage over time. Each Spiriva Respimat cartridge delivers 60 or 120 doses of 2.5 mcg each. It should be noted that, unlike other drugs where an increased dosage might be tested if there's no response after a few weeks, with Spiriva Respimat it is important not to exceed the recommended daily dose as this can lead to side effects such as dry mouth and urinary retention.
What are the most common side effects for Spiriva?
Common side effects of both Spiriva and Spiriva Respimat include:
- Dry mouth
- Sinusitis (inflammation of the sinus cavities in the head)
- Pharyngitis (inflammation in the back of the throat)
- Upper respiratory tract infection
- Urinary tract infection
- Bladder obstruction
- Cough and hoarseness
- Indigestion, constipation or diarrhea

Are there any potential serious side effects for Spiriva Respimat?
While both Spiriva and Spiriva Respimat are effective medications for COPD, the Respimat version may cause certain side effects that you should be aware of. These include:
- An allergic reaction, which may present as hives; difficulty breathing; swelling in your face, lips, tongue or throat
- Eye pain or discomfort, blurred vision, red eyes and seeing halos around lights (signs of a new or worsening eye condition called narrow-angle glaucoma)
- Problems with urination (painful urination, difficulty passing urine)
- Pounding heartbeats or fluttering in your chest
- Sores or white patches on your mouth and lips (oral thrush)
- Severe constipation
If you experience any such signs while using Spiriva Respimat contact your healthcare professional immediately.
Contraindications for Spiriva and Spiriva Respimat?
Both Spiriva and Spiriva Respimat are bronchodilators used to treat chronic obstructive pulmonary disease (COPD) including emphysema and chronic bronchitis. If you notice your symptoms worsening, such as increased shortness of breath or wheezing, please seek immediate medical attention.
Neither Spiriva nor Spiriva Respimat should be taken if you are allergic to tiotropium or ipratropium (Atrovent). Always tell your physician which medications you are taking; there may be possible drug interactions with other anticholinergic drugs.
Spiriva Handihaler and Spiriva Respimat deliver the same medication but in different ways. The HandiHaler device uses a powder form while the Respimat delivers it in mist form using a cartridge system. It is important that patients understand how to use their specific device correctly for maximum treatment benefits.
How much do Spiriva and Spiriva Respimat cost?
For the brand name versions of these drugs:
- The price for a month's supply (30 capsules) of Spiriva HandiHaler (18 mcg) averages around $460, which works out to roughly $15/day.
- Meanwhile, Spiriva Respimat (2.5 mcg), also comes in a 30 days' supply but costs about $540 per inhaler, averaging at approximately $18/day.
Thus, if you are using the recommended dosage for either medication (one puff daily), then brand-name Spiriva Respimat is more expensive on a per-day treatment basis. It's important to note that cost should not be your primary consideration when determining which drug is right for you - effectiveness and side effects should be given equal or greater weight.
Currently there are no generic versions available for either of these two forms of tiotropium bromide in the United States due to patent protection laws. So, unfortunately patients do not have cheaper alternatives yet.
Popularity of Spiriva and Spiriva Respimat
Tiotropium, marketed under the brand names Spiriva and Spiriva Respimat, is a bronchodilator used to manage chronic obstructive pulmonary disease (COPD) and asthma.
Spiriva HandiHaler was estimated to have been prescribed to about 5.1 million people in the US in 2020. It accounted for just over 15% of COPD prescriptions in the country. However, it seems to be one of the most commonly prescribed anticholinergic inhalers (not classified as a beta-2 agonist or other broad class of bronchodilators). The prevalence of Spiriva has been generally increasing since its introduction.
On the other hand, Tiotropium Bromide (Spiriva Respimat), although similar in function and chemical composition, was prescribed to approximately 2.3 million people in the USA during that same year. In terms of COPD prescriptions within America, this drug accounts for roughly about 7%. Despite having less overall prescription numbers compared with its counterpart, Spiriva Respimat's use has also increased steadily over recent years due to advantages such as ease of use and better drug delivery.
Conclusion
Both Spiriva (tiotropium bromide) and Spiriva Respimat are well-established in the management of chronic obstructive pulmonary disease (COPD), including bronchitis and emphysema. Numerous clinical studies and meta-analyses have shown both to be more effective than placebo treatments at improving lung function, reducing flare-ups, and enhancing overall quality of life for COPD patients.
The main difference lies in their delivery mechanisms: while Spiriva is delivered via a dry powder inhaler called HandiHaler, Spiriva Respimat delivers the medication as a slow-moving mist that makes it easier to inhale. Although they contain the same active ingredient, these two products cannot be substituted for each other without doctor's approval due to differences in dosing.
In terms of cost considerations, both medications may present financial challenges for some individuals as there are currently no generic options available on the market.
Regarding side effects profiles, both drugs generally exhibit similar side effects such as dry mouth or throat irritation. However, because Spiriva Respimat has a softer spray pattern that can result in higher deposition of medicine into lungs with less waste compared to traditional inhalers like HandiHaler used with original Spiriva capsules, it might lead to fewer systemic adverse reactions.
Patients using either form must monitor their breathing regularly when initiating treatment or adjusting dosage levels under the guidance of healthcare professionals; immediate medical help should be sought if symptoms worsen significantly or suddenly.
