The study of milk-related excipient prevalence in 165 antiasthmatic medicines, based on the information included in the Summary of Product Characteristics, revealed the presence of lactose in more than one third of these medicines. Since lactose may suffer cross-contamination with cow’s milk protein, these results are an alert to health professionals.engExcipientsLactoseCow’s milk protein allergyother10.3390/msf2021005032
