Medscape Drug Interaction Checker vs PrecisePK
A clinician checking two drugs, an herb or a food can use Medscape's checker, a WebMD property. A 2016 comparison of five interaction software programs, run on an older version, scored it 202 of 400 against 250 for Lexi-Interact and Epocrates. A transplant interaction study found it rating cyclosporine with lercanidipine as no interaction while Lexicomp and Micromedex rated it severe. In a herb-oncology drug screening, Lexicomp did best and Medscape was the best free tool.
A hospital pharmacist targeting busulfan exposure from a serum level is PrecisePK's customer. The vendor names the U.S. Department of Veterans Affairs and Stony Brook University Hospital among its customers and states SOC 2, ISO 27001, HIPAA and GDPR. Flagging a clash between two drugs and turning a busulfan level into a dose are different tasks on different inputs, a drug list in one case and a measured concentration in the other.
