In 2017 we added 17 new injectable drugs, new compatibility information for 263 drugs, and new stability information for 44 drugs. IV compatibility modules included in other products do not specify what is included in their updates, and are prepared by staff pharmacists. At King Guide, we list every drug that is updated each quarter on our website so you can be aware of new and updated information and our editor is the only remaining authority that has done this work exclusively for the last 25 years.
