Relvar: optimal size for absorption1,2

Asthma control is influenced by many factors and one often overlooked aspect is particle size.

Relvar’s particle size of 2.3–4.0 μm1 falls well within the optimal range for absorption of 1.0–5.0 μm.2

There is no evidence that extra fine particles offer any additional clinically relevant benefits compared with standard ICS/LABA particle sizes.3

Relvar – molecules selected for their longer duration of action vs beclomethasone*4,5

Molecule Icon

Relvar is longer acting and more targeted to the appropriate receptors, compared with beclomethasone dipropionate (BDP)/formoterol (Form) (in vitro data)*4–6

Lungs Icon

Relvar provides significantly greater improvement in lung function vs BDP/Form at 12 months (99% vs 92% FEV1 predicted, p<0.01)7
