1. What is Stiolto Respimat®?

Component	Drug	MOA	Typical Use
Umeclidinium bromide	Long‑acting muscarinic antagonist (LAMA)	Blocks M3 receptors → bronchodilation, reduced airway resistance	Maintenance bronchodilation in COPD
Vilanterol	Long‑acting β2‑agonist (LABA)	β2‑adrenergic agonist → smooth‑muscle relaxation	Maintenance bronchodilation in COPD and asthma

• Device: Respimat® soft‑mist inhaler – delivers a fine mist for efficient lung deposition.
• Dose per puff: 2.5 µg umeclidinium + 2.5 µg vilanterol (≈ 5 µg total).
• Cartridge weight: ~4 g (the “4 g” in the package refers to the total mass of the inhaler cartridge, not the drug dose).

2. Indications

Condition	Patient group	Frequency of use
COPD (emphysema, chronic bronchitis)	Adults ≥18 y	Twice daily (morning & evening)
Asthma (maintenance therapy)	Adults & adolescents ≥12 y	Twice daily

Note: It’s not a rescue inhaler. Use it only as prescribed for regular, long‑term control.

3. How to Use

1. Shake the inhaler 10‑15 times before each use.
2. Prime the device if it’s the first dose or hasn’t been used in >2 days (usually 2–3 puffs).
3. Inhale slowly and deeply while pressing the inhaler.
4. Hold breath for ~5 s (if possible) before exhaling.
5. Repeat for the second puff.
6. Rinse mouth after use (especially with LABAs) to reduce oral thrush risk.

Tip: Use a spacer only if you have difficulty coordinating inhalation with actuation; the Respimat is designed for direct inhalation, so a spacer isn’t typically needed.

4. Dosage

Condition	Dose	Frequency
COPD (maintenance)	2.5 µg / 2.5 µg twice daily	Twice daily
Asthma (maintenance)	2.5 µg / 2.5 µg twice daily	Twice daily

Adjustments:

• CYP2D6 poor metabolizers: may have higher vilanterol exposure; monitor for bronchospasm or tremor.
• Severe renal/hepatic impairment: not formally studied; use with caution.

5. Common Adverse Effects

Symptom	Frequency	How to manage
Dry mouth, throat irritation	~10–20 %	Rinse mouth, drink water
Upper‑respiratory infections	~5–10 %	Treat with antibiotics if bacterial
Tremor, palpitations	~5 %	Consider dose reduction or switch to LAMA alone
Nasal congestion	<5 %	Decongestants (short‑term)
Increased intraocular pressure (rare)	<1 %	Ophthalmologic monitoring in glaucoma pts

Serious but rare: bronchospasm, paradoxical bronchoconstriction, chest pain, heart failure exacerbation.

6. Contraindications & Precautions

• Contraindications:
  • Known hypersensitivity to umeclidinium, vilanterol, or any inhaler excipients.
  • Severe asthma attack or acute exacerbation (use rescue inhaler).
• Precautions:
  • Cardiovascular disease: Vilanterol can increase heart rate & blood pressure; monitor.
  • Diabetes: β‑agonist can raise blood glucose; monitor HbA1c.
  • Pregnancy & lactation: Limited data; use only if benefits outweigh risks.
  • Pediatric (<12 y): Not approved for asthma in children <12 y; for COPD in younger adults, evidence is limited.

7. Drug Interactions

Drug	Effect	Management
β‑blockers (non‑selective)	May blunt bronchodilation	Use cardioselective β1‑blocker if necessary
CYP2D6 inhibitors (e.g., fluoxetine)	↑ Vilanterol plasma levels	Monitor for β‑agonist toxicity; consider dose adjustment
MAO‑I inhibitors	↑ β‑agonist risk	Avoid combination
Other bronchodilators (e.g., salmeterol)	Additive effects	Avoid duplication; adjust therapy accordingly

General rule: If starting a new drug that may affect β‑agonist activity, monitor for tachycardia, tremor, or palpitations.

8. Storage & Expiry

• Temperature: Store below 30 °C (86 °F).
• Humidity: Keep dry.
• Expiry: Check the “best before” date on the cartridge. Do not use past expiry.

9. Misconceptions & FAQ

Question	Answer
Is Stiolto a rescue inhaler?	No. It’s a maintenance therapy. Use only as prescribed; for acute wheeze, use a short‑acting β2‑agonist.
Can I use it for asthma?	Yes, as maintenance therapy for adults and adolescents ≥12 y, but not for acute attacks.
How many puffs per day?	Two puffs twice daily (total four puffs/day).
Why is it called “4 g”?	The inhaler cartridge weighs about 4 g; the drug dose per puff is only 5 µg total.
What if I miss a dose?	Take the missed dose as soon as you remember. Skip if it’s close to the next scheduled dose.

10. When to Seek Medical Attention

• Sudden worsening of breathing (dyspnea, wheeze).
• Chest pain or palpitations.

Bottom line

Stiolto Respimat® (2.5 µg / 2.5 µg) is a once‑daily inhaled combination of a LAMA and a LABA used for long‑term bronchodilation in COPD and asthma. Use it as prescribed, keep the cartridge dry and below 30 °C, and monitor for side effects, especially in patients with cardiovascular disease or on interacting medications. If you have any doubts about dosing, interactions, or side effects, always consult your healthcare provider.
