Salmeterol + Fluticasone

Fixed-dose combination: long-acting beta-2 agonist (LABA) plus inhaled corticosteroid (ICS)

ATC code: R03AK06(Salmeterol and fluticasone)

Updated 24 Sep 2026 · Methodology

Indications

Asthma

First line

Asthma at step 3 and above – patients not controlled on low-to-medium ICS monotherapy. Per GINA 2024, fixed ICS-LABA is the backbone of steps 3–5 controller therapy. Salmeterol/fluticasone dose: 50/100, 50/250, 50/500 µg twice daily (Accuhaler/Diskus) or 25/50, 25/125, 25/250 µg as 2 inhalations twice daily (HFA inhaler). Reassess at 4–12 weeks; if stable for 3 months, step down to lower dose or drop LABA while keeping ICS.

Chronic obstructive pulmonary disease

Second line

COPD with frequent exacerbations (≥2/year or ≥1 with hospitalization) and eosinophils ≥300 cells/µL. Per 2024, ICS-LABA is added to LAMA or used as part of triple therapy LAMA+LABA+ICS. Dose: 50/500 µg twice daily. Before starting, discuss increased pneumonia risk (NNH ~14 per year). Reassess at 12 months.

How to read tiers A–F

AStrong evidence – first or second line in international guidelines
BRecommended in selected cases
CStudy data contradict each other
DBenefit not proven, no documented harm
FDocumented harm, or risk without benefit

Mechanism of action

Salmeterol selectively stimulates bronchial beta-2 adrenoceptors with a 12-hour duration – relaxes smooth muscle and dilates bronchi. Fluticasone suppresses mucosal inflammation through glucocorticoid receptors. The LABA + ICS combination outperforms doubling the ICS dose and reduces exacerbations. Never use LABA as monotherapy in asthma – risk of fatal exacerbations (SMART 2006).

Safety

Contraindications

Hypersensitivity to components
History of paradoxical bronchospasm with LABA
Active tuberculosis without antitubercular therapy
LABA monotherapy in asthma (ICS component required)

Serious adverse effects

Pneumonia in COPD patients
Paradoxical bronchospasm immediately after inhalation
Arrhythmias (atrial fibrillation, tachycardia)
Hypokalemia at high doses
Systemic glucocorticoid effects at high cumulative doses

Common adverse effects

Oral candidiasis
Hoarseness
Tremor
Palpitations
Headache
Throat irritation

Pregnancy: can you take Salmeterol + Fluticasone?

Use when clearly needed. Asthma control outweighs theoretical risk. In women of reproductive age, budesonide + formoterol is preferred (more pregnancy data).

Breastfeeding: can you take Salmeterol + Fluticasone?

Compatible. Hale L2. Systemic absorption of inhaled ICS and LABA is minimal.

Practical notes

Timing and administration

Rinse and spit after each inhalation. Do not use as a rescue inhaler – LABA does not act fast enough. For acute symptoms – short-acting beta-2 agonist (salbutamol).
