Analysis of clarithromycin potential adverse drug interactions and establishment of refined prescription pre-review rules
To analyze the potential adverse drug interactions (pADIs) of clarithromycin, and establish refined prescription pre-review rules.
METHODS
2
Outpatient prescriptions of clarithromycin in combination with other drugs were collected from January 1, 2024 to June 30, 2024 through hospital information system of the Third People’s Hospital of Bengbu. pADIs were identified and their risk severities were graded according to Lexicomp and Micromedex databases. Then, refined prescription pre-review rules for clarithromycin pADIs-related drugs were established according to the identification and risk level results.
RESULTS
2
Among 3 046 clarithromycin combined drug prescriptions, 946 cases of pADIs occurred in 812 prescriptions. There were 6, 415 and 525 cases classified as “contraindicated”, “major” and “moderate”, respectively. The combination drugs with “contraindicated” levels were tamsulosin, rupatadine, domperidone and ticagrelor, while those with “major” levels were mainly theophylline, dexamethasone and amlodipine. Accordingly, 26 refined rules were established, including 4 items of “warning information→prescription interception”, 11 items of “warning information→prescription double signature” and 11 items of “attention information→prescription approval”.
CONCLUSIONS
2
There are “contraindicated” and “major” risks associated with clarithromycin and its combination drugs in the hospital, and refined prescription pre-review rules for clarithromycin combined drug prescription have been established successfully.
