Without much fanfare (yet), we now have a combination steroid + bronchodilator treatment licensed for use as needed in "mild" asthma. No maintenance therapy, just as needed, so it's not MART.
This has been part of GINA guidelines for some time, and widely recognised as a better way of treating asthma, but so far we've not had any licensed products.

The emerging popular name for this type of treatment is AIR, anti-inflammatory reliever therapy. It's important not just because it simplifies therapy for patients, reduces severe exacerbations, and is a cost-effective strategy. It also reduces carbon footprint massively (perhaps 30-fold) compared to the traditional blue + brown puffers, which the large majority of UK asthma patients are given.

The license is for Symbicort 200/6 in patients over 12 with mild asthma.

Dunno if you would step up from PRN to MART.
Maybe PRN if the patient is only using ONE inhaler. Start on ICS then ICS/LABA fixed, then MART if appropriate.
MART is the future though
