Hello Aspirant,

As am a pharmD intern , I mostly prefer LEXICOM book for the quick review,
But sometimes when I will be during Ward rounds I prefer Medacape and drugs.com because time won't be sufficient to go or refer a book .

Some of the good books are given below :

1:Philip D Hansten
2: Stockley's drug interactions.
3: Drug interaction facts 2019 or 2018

I hope the above information is useful to you ,
Prepare well ,

All the best !
