I am trying to look up data on the ingredient milbemycin oxime, and I want results that contain only milbemycin oxime as the active ingredient.
returns 0 results. This cannot be the case as there are several pet medicines with milbemycin oxime as the sole active ingredient for which I know adverse reaction events have been reported.
I also tried "spinosad" (Comfortis single active ingredient) and again 0 results.
However, there are many results when a query allows for multiple active ingredients.
Thanks in advance!
