Whatever you want to know about your medications, DrugBank can tell you. Seriously. Each of the nearly 4,100 drugs on the site has 80 data fields covering names and chemical structures to how and why the drug works to patient information and helpful websites.
The information on Topamax, ibuprofen and Imitrex, which are some common headache drugs, is impressive. DrugBank also links to popular drug sites, including Drugs.com and RX List, when readers want more information.
