 +==== Notes ====
 +
 +There is a problem that NDC can update the vocabulary using the same concepts for a different drug concepts:
 +in the 18/12/17 release we found out that:
 +
 +44865343 "​Aminophylline 200 MG Oral Tablet"​ changed to  "​Cephalexin 500 MG Oral Capsule" ​
 +
 +45092451 "​Aluminum Hydroxide 200 MG / Magnesium Hydroxide 200 MG Oral Tablet [Rulox #​1]" ​ changed to "​Allopurinol 100 MG Oral Tablet"​
 +
 +45084807 "​GLIMEPIRIDE 4 MG TABLET"​ changed to "​Naproxen sodium 550 MG Oral Tablet"​
 +(number provided is the concept_id)
 +
 +so these concepts totally changed their meaning during the update
