The database that the API refers to, doesn't seem to be insync with what the UI shows on the website. And it seems to have happened recently.
I would query for : Human Prescription drugs NDA/BLA "obesity" under "Usage and Indications".
Previously it would return 14 or so results as in the UI (20 in the UI, but the API doesn't return the old versions of the Label) . Now it does not? it only returns 10!
