Prospective,multi-center,and large-scale hospital centralized monitoring of clinical safety of Reduning Injection in 100 249 children cases
This study utilized a prospective,large-sample,multi-center,and registered key specialty approach of hospitals to monitor the application of Reduning Injection.A total of 100 249 adolescent patients aged 14 years and below who received Reduning Injection were monitored,resulting in 83 cases of adverse events,with 76 of them being classified as adverse drug reaction(ADR).The calculated incidence rate of ADR for Reduning Injection was 0.076%,indicating a very rare ADR.The main symptoms of ADR were pruritus,diarrhea,abdominal pain,vomiting,high fever,dyspnea,convulsion,and chills.All ADR cases were reported for the first time,including three new ADR cases and 73 known ADR cases.The categories of ADR was general ADR.All ADR was mild in severity.There were more males than females in ADR patients.One patient had a history of ADR,and the drug causing ADR was buprofen.The largest number of ADR cases occurred when the dosage of Reduning injection was 5-10 mL.The dropping speed was 30 drops or less per min,and the solvent type was 5%glucose injection.The most common manifestation of ADR patients was pruritus,followed by diarrhea,abdominal pain,vomiting,high fever,dyspnea,convulsions,and chills.72 patients(94.74%of ADR patients)discontinued the drug,and three patients(3.95%of ADR patients)were given oxygen inhalation.47 cases(61.84%of ADR patients)were treated with medication,of which dexamethasone was the most used(24 cases,46.15%of ADR patients).76 ADR patients were cured or improved.ADRs are more likely to occur when diagnosed with acute bronchitis by western medicine and cough by traditional Chinese medicine(TCM),TCM syndrome type is wind heat syndrome,and the combination medicine is ambroxol hydrochloride and bromhexine hydrochloride injection,ascorbic acid/vitamin C injection.This result provides an evidence-based safety basis for active pharmacovigilance of Reduning Injection in adolescents aged 14 years and below.
