Tiotropium bromide, sold under the brand name Spiriva among others, is a long-acting bronchodilator (LAMA: long acting muscarinic antagonist) used in the management of chronic obstructive pulmonary disease (COPD) and asthma. [10] [11] Specifically it is used during periods of breathing difficulty to prevent them from getting worse, rather than to prevent them from happening. [10] It is used by inhalation through the mouth. [10] Onset typically begins within half an hour and lasts for 24 hours. [10]
Common side effects include a dry mouth, runny nose, upper respiratory tract infection, shortness of breath and headache. [10] Severe side effects may include angioedema, worsening bronchospasm, and QT prolongation. [10] Tentative evidence has not found harm during pregnancy, however, such use has not been well studied. [1] It is an anticholinergic medication and works by blocking acetylcholine action on smooth muscle. [10]
Tiotropium was patented in 1989, and approved for medical use in 2002. [12] It is on the World Health Organization's List of Essential Medicines. [13] In 2020, it was the 110th most commonly prescribed medication in the United States, with more than 5 million prescriptions. [14] [15]
Tiotropium is used as maintenance treatment of chronic obstructive pulmonary disease (COPD). [16] [17] It may also be used as an add-on therapy in people with moderate-to-severe asthma on medium to high dose inhaled corticosteroids (ICS). [18] [19] It is not however approved for acute exacerbations of COPD or acute worsening of asthma. [10]
Tiotropium is also used in a combination inhaler with olodaterol, a long-acting beta-agonist, for the treatment of COPD, under the brand names Stiolto and Spiolto among others. [20] [21] [22]
Adverse effects are mainly related to its antimuscarinic effects. Common adverse drug reactions (≥1% of people) include: dry mouth and/or throat irritation. Rarely (<0.1% of patients) treatment is associated with: urinary retention, constipation, acute angle closure glaucoma, palpitations (notably supraventricular tachycardia and atrial fibrillation) and allergy (rash, angioedema, anaphylaxis). [23] A 2006 review found the increase in bronchospasm was small and did not reach statistical significance. [24]
Data regarding some serious side effects is mixed as of 2020. [10] In September 2008 a review found that tiotropium and another member of its class ipratropium may be linked to increased risk of heart attacks, stroke and cardiovascular death. [25] The US FDA reviewed the concern and concluded in 2010 that this association was not supported. [16] [26] A 2011 review of the tiotropium mist inhaler (Respimat); however, still found an associated with an increase in all cause mortality in people with COPD. [27]
Tiotropium is a muscarinic receptor antagonist, often referred to as an antimuscarinic or anticholinergic agent. Although it does not display selectivity for specific muscarinic receptors, when topically applied it acts mainly on M3 muscarinic receptors [28] located on smooth muscle cells and submucosal glands. This leads to a reduction in smooth muscle contraction and mucus secretion and thus produces a bronchodilatory effect.[ citation needed ]
Tiotroprium is available in two inhaler formats: a soft mist inhaler (Respimat) and a dry powder inhaler (HandiHaler). [29] The safety and efficacy profiles of both devices are comparable and people's preference should play a role in determining inhaler choice. [29] There is no significant difference in all-cause mortality between tiotropium soft mist inhalers compared to dry powder inhalers, however caution needs to be taken in people with severe heart or kidney problems. [30]
A bronchodilator or broncholytic is a substance that dilates the bronchi and bronchioles, decreasing resistance in the respiratory airway and increasing airflow to the lungs. Bronchodilators may be originating naturally within the body, or they may be medications administered for the treatment of breathing difficulties, usually in the form of inhalers. They are most useful in obstructive lung diseases, of which asthma and chronic obstructive pulmonary disease are the most common conditions. Although this remains somewhat controversial, they might be useful in bronchiolitis and bronchiectasis. They are often prescribed but of unproven significance in restrictive lung diseases.
Ipratropium bromide, sold under the trade name Atrovent among others, is a type of anticholinergic medication which opens up the medium and large airways in the lungs. It is used to treat the symptoms of chronic obstructive pulmonary disease and asthma. It is used by inhaler or nebulizer. Onset of action is typically within 15 to 30 minutes and lasts for three to five hours.
Budesonide/formoterol, sold under the brand name Symbicort among others, is a fixed-dose combination medication used in the management of asthma or chronic obstructive pulmonary disease (COPD). It contains budesonide, a steroid and formoterol, a long-acting β2-agonist (LABA). The product monograph does not support its use for sudden worsening or treatment of active bronchospasm. However, a 2020 review of the literature does support such use. It is used by breathing in the medication.
Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle and liver, relaxation of uterine muscle, and release of insulin. They are primarily used to treat asthma and other pulmonary disorders, such as Chronic obstructive pulmonary disease (COPD).
Bronchoconstriction is the constriction of the airways in the lungs due to the tightening of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath.
Long-acting β adrenoceptor agonists are usually prescribed for moderate-to-severe persistent asthma patients or patients with chronic obstructive pulmonary disease (COPD). They are designed to reduce the need for shorter-acting β2 agonists such as salbutamol (albuterol), as they have a duration of action of approximately 12 hours in comparison with the 4-to-6-hour duration of salbutamol, making them candidates for sparing high doses of corticosteroids or treating nocturnal asthma and providing symptomatic improvement in patients with COPD. With the exception of formoterol, long-acting β2 agonists are not recommended for the treatment of acute asthma exacerbations because of their slower onset of action compared to salbutamol. Their long duration of action is due to the addition of a long, lipophilic side-chain that binds to an exosite on adrenergic receptors. This allows the active portion of the molecule to continuously bind and unbind at β2 receptors in the smooth muscle in the lungs.
Indacaterol is an ultra-long-acting beta-adrenoceptor agonist developed by Novartis. It needs to be taken only once a day, unlike the related drugs formoterol and salmeterol. It is licensed only for the treatment of chronic obstructive pulmonary disease (COPD). It is delivered as an aerosol formulation through a dry powder inhaler.
Roflumilast, sold under the trade name Daxas among others, is a drug that acts as a selective, long-acting inhibitor of the enzyme phosphodiesterase-4 (PDE-4). It has anti-inflammatory effects and is used as an orally administered drug for the treatment of inflammatory conditions of the lungs such as chronic obstructive pulmonary disease (COPD).
Fluticasone furoate, sold under the brand name Flonase Sensimist among others, is a corticosteroid for the treatment of non-allergic and allergic rhinitis administered by a nasal spray. It is also available as an inhaled corticosteroid to help prevent and control symptoms of asthma. It is derived from cortisol. Unlike fluticasone propionate, which is only approved for children four years and older, fluticasone furoate is approved in children as young as two years of age when used for allergies.
