⚡ Quick Answer — What is Duolin Rotacaps?
Duolin Rotacaps περιέχει ipratropium bromide + levosalbutamol, used as a reliever for acute bronchospasm in asthma και COPD. The combination delivers two complementary bronchodilators in one dose: levosalbutamol (a short-acting β2 agonist with rapid 1–5 min onset) and ipratropium (a short-acting muscarinic antagonist with onset by 15 min). Combined, they provide more complete bronchodilation than either alone — particularly in COPD where parasympathetic tone is the dominant reversible component. Manufactured by Cipla. Each rotacaps delivers ipratropium 40 mcg + levosalbutamol 100 mcg per rotacap.

What Is Duolin Rotacaps?
Duolin Rotacaps is a fixed-dose combination of ipratropium and levosalbutamol manufactured by Cipla at WHO-GMP certified facilities. Internationally the same combination is sold as Combivent (DuoNeb).
How Does Duolin Rotacaps Work?
- Ipratropium blocks M1, M2, and M3 muscarinic receptors on airway smooth muscle, neutralising parasympathetic tone — onset 15 min, duration 4–6 hours.
- Λεβοσαλβουταμόλη (active R-isomer of salbutamol) activates β2 receptors, raising cyclic AMP and producing rapid bronchodilation — onset 1–5 min, duration 4–6 hours.
- Synergy: the two pathways act in parallel, giving deeper bronchodilation than either alone — particularly useful in COPD and acute severe asthma.
Χρήσεις και ενδείξεις
- Acute COPD exacerbations — first-line bronchodilator alongside or instead of a SABA
- Acute severe asthma — added to high-dose SABA in moderate-to-severe attacks (paediatric and adult)
- Chronic COPD symptomatic relief — when LAMA is unavailable or short-acting cover is preferred
- Bronchospasm secondary to viral wheeze, bronchiolitis in young children (case-by-case)
Duolin Rotacaps Dosage
| Patient | Δόση | Συχνότητα |
|---|---|---|
| Adults | 1 rotacap | Three to four times daily |
| Children >6 yr | 1 rotacap | Three times daily |
How to Use Duolin Rotacaps Properly
- Insert one rotacap into the Rotahaler with the coloured end down.
- Twist the base sharply — listen for the click.
- Breathe out fully away from device.
- Seal lips around mouthpiece.
- Inhale forcefully and deeply; you should hear the rotacap whir.
- Hold breath 10 seconds; breathe out slowly.
- Check the rotacap is empty; repeat the inhalation if powder remains.
Side Effects of Duolin Rotacaps
- Dry mouth (anticholinergic)
- Throat irritation, cough
- Mild headache
- Mild tremor and palpitations (β2 effects from levosalbutamol)
- Bitter or metallic taste
- Eye irritation if mist contacts eyes
Less common but serious:
- Acute angle-closure glaucoma (avoid mist near eyes; use mouthpiece preferred over mask)
- Acute urinary retention in patients with prostatic obstruction
- Σοβαρή αλλεργική αντίδραση
- Paradoxical bronchospasm
Προειδοποιήσεις και προφυλάξεις
- Avoid mist near eyes — risk of acute glaucoma in predisposed patients (narrow anterior chamber, family history). Use mouthpiece rather than mask where possible.
- Prostatic obstruction: caution in older men; risk of urinary retention.
- Cardiovascular disease: caution with arrhythmias and severe coronary disease (β2 component)
- Pregnancy: low-risk; uncontrolled asthma is more dangerous than the medication.
- Carry a SABA reliever for asthma rescue — ipratropium has slower onset.
Αντενδείξεις
- Hypersensitivity to ipratropium, atropine derivatives, levosalbutamol, or excipients
- Severe lactose / milk-protein hypersensitivity (DPI)
Αλληλεπιδράσεις Φαρμάκων
| Interacting drug | Αποτέλεσμα | Τι να κάνετε |
|---|---|---|
| Non-selective beta-blockers (propranolol, timolol drops) | Block β2 effect — can precipitate severe bronchospasm | Avoid; switch to cardioselective beta-blocker if essential |
| Loop or thiazide diuretics | Additive hypokalaemia | Monitor serum potassium with high doses |
| Systemic corticosteroids | Additive hypokalaemia + hyperglycaemia | Monitor electrolytes and glucose |
| Theophylline / aminophylline | Additive tachycardia and hypokalaemia | Monitor heart rate and potassium |
| MAOIs and tricyclic antidepressants | Potentiate cardiovascular effects | Caution — monitor BP/HR |
| Ντιγκοξίνη | Hypokalaemia increases digoxin toxicity risk | Monitor potassium; check digoxin level if symptomatic |
Αποθήκευση
- Store below 25°C in a dry place. Keep desiccant in the bottle.
- Do not store in the bathroom — humidity makes the powder clump and reduces dose delivery.
- Once the strip/blister is opened, use within the period stated on the leaflet (typically 2–3 months).
- Keep out of reach of children.

Συχνές Ερωτήσεις
Is Duolin the same as Combivent?
Combivent (Boehringer Ingelheim) contains ipratropium + albuterol (salbutamol). Duolin (Cipla) contains ipratropium + levosalbutamol — the active R-isomer. Clinically equivalent at half the levosalbutamol milligram dose, with potentially less tremor.
When is a SAMA + SABA combination used?
Most commonly in acute COPD exacerbations and moderate-to-severe acute asthma. In stable disease, the combination is sometimes used as an as-needed reliever, though modern guidelines favour ICS-formoterol SMART/MART for asthma.
How fast does Duolin work?
Levosalbutamol begins bronchodilation in 1–5 minutes; ipratropium adds in 15–30 minutes. Total combined duration 4–6 hours.
How often can I use Duolin?
Up to 4× daily routinely; back-to-back every 20 minutes ×3 in severe attacks under supervision.
Can children use Duolin?
Yes in age-appropriate strength under medical supervision. Often used in paediatric A&E for moderate-severe asthma attacks.
Is Duolin safe in pregnancy?
Both molecules have reassuring pregnancy data. Uncontrolled asthma is more dangerous than the combination.
Why dry mouth on Duolin?
Anticholinergic effect from ipratropium. Sips of water, gum, oral hygiene help.
Can I use Duolin Respules with budesonide?
Yes — co-nebulising Duolin with Budecort Respules in the same cup is common in moderate-to-severe acute attacks. Empty all respules into the cup; nebulise as one session.
Is Duolin a maintenance therapy?
It can be used regularly in COPD as 4× daily maintenance, though modern guidelines prefer once-daily LAMA (Tiova, Airz) ± LABA. For asthma, regular use of SABA-containing relievers is no longer recommended — switch to ICS-LABA.
