This is really more of a programming question than bioinformatics....

Your callback function already has a bunch of statements for checking the data. The variable drugNames is an array of drug Names. You can just loop through drugNames and see if the items in the array match items in your ignoredDrugName array.

Here is a rough way to do it:(untested)

var ignore = false;
for (var x = 0, countX = drugNames.length ; i < countX ; x ++ ) {
   for (var y = 0, countY = ignoredDrugName.length ; i < countY ; y++) {
      if (drugNames[x] == ignoredDrugName[y]) {
         ignore = true;

if (ignore) continue;
