Active ingredient(s)

Cromoglycates (Cromolyn sodium, Nedocromil sodium)

Inhaled anti-asthmatic — chromone

Guidance notes

Acceptable. An alternative when starting regular controller therapy in mild asthma, with a lower side-effect profile than inhaled corticosteroids, although ICS remain preferred.

Category rules that also apply

Topical preparations — 10% body surface area rule

Topical preparations are treated as acceptable only while applied to no more than 10% of body surface area (roughly one arm, or the palm-size rule ×10). Above that, systemic absorption becomes significant and the preparation is assessed as if taken systemically — including topical corticosteroids, NSAID gels and antihistamine creams. Broken or inflamed skin increases absorption further.
