In epiben/promedreadr: Read Select Pharmacovigilance Information from pro.medicin.dk

promedreadr

The goal of promedreadr is to provide a simple tool for collecting information from https://pro.medicin.dk, a key reference on medicines marketed in Denmark.

Note that the package is not yet “production ready”, especially it doesn’t yet honour robots.txt (improvement is underway and will be up shortly.)

Just because you can doesn’t mean you should

Please use this package thoughtfully as web-scraping can lead to e.g. copyright infringement. If in doubt, please contact the team behind medicin.dk.

Features

• Simple interface for querying based on ATC codes
• Marshals information from all products containing drugs with the queried ATC code(s)
• Reconciles side effects reported across products and rolls them up to the ATC code(s)
• Can produce handy, single-line lists of side effects, by frequencies

Example

library(promedreadr)

atc_codes <- c(Quetiapine = "N05AH04",
               Lithium = "N05AN01")

product_urls <- extract_product_urls(atc_codes)
all_ade_tables <- fetch_ade_tables(product_urls)
combined_ade_tables <- reconcile_ade_tables(all_ade_tables)
