Medical applications

Hi, i'm looking for Free Drug dictionary(OFFLINE) that has some features that will not only to define the drug for its indications but also show Contraindications for the drug. Just like a real Drug Handbook Guide that will show everything about the drug. In addition, I'm also looking for a BEST free Medical encyclopedia(OFFLINE) that includes some photos and videos.

I'm a nursing student and this will sure help me on my studies.

Thanks in advance..
