Andin2 is a 32-bit Windows computer program for drug information services; it is equally suited to a service being operated from a formal drug information centre as to one from a small pharmacy or department with part-time staffing.

The original ANDIN was a DOS program, its purpose being to allow you to create your own database. Andin2 extends ANDIN with new features and all the benefits of working in the Windows environment. A new installation of ANDIN or Andin2 is an 'empty database' waiting for you to enter your own data. An upgrade installation migrates all of your data from the old program into the new one.
