Tiova Inhaler (Tiotropium Bromide) is a long-acting muscarinic antagonist (LAMA) inhaler designed for the maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. It offers sustained 24-hour bronchodilation with a single daily dose, improving lung function, reducing exacerbations, and enhancing exercise tolerance. Its dry powder formulation ensures consistent drug delivery, making it a cornerstone in the long-term management of airflow obstruction.
Features
- Active ingredient: Tiotropium Bromide (18 mcg per inhalation)
- Delivery system: Breath-activated dry powder inhaler (DPI)
- Dosage form: Hard gelatin capsules containing a powder blend for inhalation
- Mechanism: Long-acting muscarinic antagonist (LAMA)
- Duration of action: 24 hours
- Packaging: Blister strips of 10 capsules; 30 capsules per pack
Benefits
- Provides sustained 24-hour bronchodilation, reducing the need for frequent dosing.
- Significantly improves lung function (FEV1) and exercise capacity in COPD patients.
- Reduces the frequency and severity of COPD exacerbations.
- Enhances quality of life by decreasing breathlessness and nighttime symptoms.
- Low systemic absorption minimizes the risk of systemic anticholinergic side effects.
- Convenient once-daily dosing supports adherence to long-term therapy.
Common use
Tiova Inhaler is indicated for the long-term, once-daily maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD). It is not intended for use as a rescue medication for acute bronchospasm. It is commonly prescribed for patients with moderate to severe COPD who require regular bronchodilator therapy to control symptoms and prevent exacerbations.
Dosage and direction
The recommended dosage is the inhalation of the contents of one Tiova capsule (18 mcg tiotropium) once daily, at the same time each day, using the Tiova Inhaler device. The capsule must only be used with the designated inhaler and must not be swallowed. Instructions for use:
- Open the dust cap and mouthpiece.
- Place the capsule in the chamber; close the mouthpiece until a click is heard.
- Hold the inhaler upright and press the piercing button fully once.
- Breathe out fully, place mouthpiece between lips, and inhale deeply and steadily.
- Hold breath for 10 seconds, then exhale slowly away from the device.
- Repeat inhalation to ensure full dose delivery if needed.
- Open and discard the empty capsule; close the device.
Precautions
- Not for use in the treatment of acute bronchospasm; always have a rescue inhaler (e.g., SABA) available.
- Use with caution in patients with narrow-angle glaucoma, prostatic hyperplasia, or bladder neck obstruction due to anticholinergic effects.
- Monitor for signs of paradoxical bronchospasm; discontinue immediately if it occurs.
- Avoid getting powder in the eyes, as it may cause blurring of vision or pupil dilation.
- Not recommended for use in patients with severe hypersensitivity to milk proteins (contains lactose).
- Renal impairment: Use with caution in patients with moderate to severe renal impairment (creatinine clearance ≤50 mL/min).
Contraindications
- Hypersensitivity to tiotropium bromide, atropine or its derivatives, or any component of the formulation (including lactose).
- Not indicated for the treatment of asthma; safety and efficacy not established in asthmatic patients.
Possible side effects
Common side effects (≥1/100 to <1/10):
- Dry mouth
- Constipation
- Pharyngitis
- Sinusitis
- Dyspepsia
- Abdominal pain
- Upper respiratory tract infection
- Cough
Less common side effects (≥1/1000 to <1/100):
- Tachycardia
- Palpitations
- Urinary retention
- Glaucoma (angle-closure)
- Skin rash
- Hoarseness
- Oral candidiasis
Rare side effects (<1/1000):
- Allergic reactions (angioedema, urticaria)
- Paradoxical bronchospasm
- Dizziness
Drug interaction
- Concomitant use with other anticholinergic-containing drugs (e.g., ipratropium, aclidinium) may potentiate anticholinergic adverse effects and is not recommended.
- No clinically significant pharmacokinetic interactions observed with commonly co-administered drugs such as sympathomimetic bronchodilators, methylxanthines, or oral or inhaled corticosteroids.
- Caution advised when used with drugs that are excreted renally or affect renal function.
Missed dose
If a dose is missed, it should be taken as soon as remembered on the same day. However, if it is almost time for the next dose, the missed dose should be skipped and the regular dosing schedule resumed. Do not double the dose to make up for a missed one.
Overdose
Overdose may lead to exaggerated anticholinergic effects such as dry mouth, visual disturbances, tachycardia, urinary retention, and constipation. Severe overdose could result in cardiac arrhythmias or central nervous system effects. Treatment is symptomatic and supportive; there is no specific antidote. Dialysis is not effective due to high protein binding and extensive tissue distribution.
Storage
Store below 25°C in a dry place. Protect from moisture and direct light. Keep capsules in the blister until immediately before use. Do not store the inhaler device with a capsule inside. Keep out of reach of children and pets. Do not use after the expiration date.

Reviews
Clinical studies and patient reports consistently highlight the efficacy of Tiova Inhaler in improving lung function and reducing exacerbations in COPD. Patients often report better symptom control and increased ability to perform daily activities. Dry mouth is a frequently mentioned side effect but is generally manageable. Healthcare providers appreciate its once-daily dosing, which supports long-term adherence. As with any medication, individual experiences may vary.
