amboss has “Preventive treatment prior to exercise” for them under https://next.amboss.com/us/article/Ph0WVf?q=nedocromil+sodium#Zccfbd9034a4206efbc4b7a368c25937f
their reference is https://www.accessdata.fda.gov/drugsatfda_docs/label/2004/18596slr030_intal_lbl.pdf
AMBOSS source is from 2004… don’t love that. UpToDate says cromoglycate for EIB refractory to SABA or pt intolerant to SABA and further clarifies choice between levalbuterol, LTRA, ipratropium, and cromoglycate is based on drug availability and patient/clinician preference - UpToDate
the actual answer to this card is SABA. updating accordingly
