I have checked and am happy with the code list. I would be inclined to exclude Zafirlukast, as prescribing is minimal as there is no licensed products, and patients may not be similar cohort to montelukast patients.

Discussed with @ianjdouglas . Final decision to leave zafirlukast as it is being used as descriptive.
