The Structured Product Labels (SPLs) are all as supplied from the drug packager. That means none of them is suitable for displaying general information about the generic drug, like "ibuprofen" rather than "Advil" - even the generic listings you find will be for something like "Some-Company Ibuprofen". So, if I search for gabapentin I will find hundreds of results, but each of them makes reference to the company that makes the particular product. For instance, this is one of the gabapentin medication guides found by that search, and it includes the name and phone number of the company that makes it, and further it only has information about capsule, not other forms. (By contrast, this other manufacturer's product label talks about capsules, tablets and suspensions, since they make all those forms.)
I know you can find similar company-specific information on OpenFDA, such as this JSON document describing the same product as the first medication guide I linked to above; that has the same issues as the data straight from DailyMed.
So, is there a way through DailyMed or some other source to get information for a generic drug, without packager/manufacturer-specific information? To use an RxNorm term, I'm looking for information about a "concept" rather than a "brand".
